'''Google Search''' (also known simply as '''Google''' or '''Google.com''') is a [[search engine]] operated by [[Google]]. It allows users to search for information on the [[Internet]] by entering keywords or phrases. Google Search uses [[algorithm]]s to analyze and rank [[website]]s based on their relevance to the search query. It is the most popular search engine worldwide.
'''Google''' is the most popular [[search engine]] on the [[World Wide Web]]. Through its [[website]] and client websites, such as [[AOL]], Google receives at least 200 million search requests per day. Google has its headquarters (called the "Googleplex") in [[Mountain View, Santa Clara County, California|Mountain View]], [[California]], [[United States|USA]].


As of 2020, Google Search has a 92% share of the global search engine market.<ref>{{Cite web |title=Search Engine Market Share Worldwide {{!}} StatCounter Global Stats |url=http://gs.statcounter.com/search-engine-market-share |access-date=April 9, 2021 |website=StatCounter Global Stats |archive-date=December 10, 2020 |archive-url=https://web.archive.org/web/20201210182621/https://gs.statcounter.com/search-engine-market-share |url-status=live }}</ref> By 2012, it handled more than 3.5 billion searches per day.<ref>{{Cite web |title=Google Search Statistics - Internet Live Stats |url=http://www.internetlivestats.com/google-search-statistics/ |access-date=April 9, 2021 |website=www.internetlivestats.com |language=en |archive-date=February 4, 2015 |archive-url=https://web.archive.org/web/20150204095944/http://www.internetlivestats.com/google-search-statistics/ |url-status=live }}</ref>
In addition to web pages, Google also provides services for searching images, [[Usenet]] [[newsgroup]]s, news sites, and items for sale online. [[As of June 2004]], Google contained 4.28 billion web pages, 880 million images and 845 million Usenet messages in its index; a total of 6 billion items. It also [[cache]]s much of the content that it indexes.


Google Search is the [[List of most visited websites|most-visited website in the world]]. Approximately 26.75% of Google's monthly global traffic comes from the [[United States]], 4.44% from [[India]], 4.4% from [[Brazil]], 3.92% from the [[United Kingdom]] and 3.84% from [[Japan]] according to data provided by [[Similarweb]].<ref>{{cite web|url=https://www.similarweb.com/website/google.com/#geography|title=google.com|website=similarweb.com}}</ref>
"[[Google (verb)|To google]]", as a verb, has come to mean "to search for something on Google;" because of Google's popularity (80% of all web users, perhaps) it has also generically come to mean "to search the web." Google officials have expressed discouragement for this usage of their company name, as it could lead to their name becoming a [[genericized trademark]].


The order of search results returned by Google is based, in part, on a priority rank system called "[[PageRank]]". Google Search also provides many different options for customized searches, using symbols to include, exclude, specify or require certain search behavior, and offers specialized interactive experiences, such as flight status and package tracking, weather forecasts, currency, unit, and time conversions, word definitions, and more.
==The company==


The main purpose of Google Search is to search for text in publicly accessible documents offered by web servers, as opposed to other data, such as [[Image search|images]] or [[Database search engine|data contained in databases]]. It was originally developed in 1996 by [[Larry Page]], [[Sergey Brin]], and [[Scott Hassan]].<ref name="vanityfair">{{Cite web |last=Fisher |first=Adam |date=July 10, 2018 |title=Brin, Page, and Mayer on the Accidental Birth of the Company that Changed Everything |url=https://www.vanityfair.com/news/2018/07/valley-of-genius-excerpt-google |access-date=August 23, 2019 |website=[[Vanity Fair (magazine)|Vanity Fair]] |archive-date=July 4, 2019 |archive-url=https://web.archive.org/web/20190704184309/https://www.vanityfair.com/news/2018/07/valley-of-genius-excerpt-google |url-status=live }}</ref><ref>{{Cite magazine |last=McHugh |first=Josh |date=January 1, 2003 |title=Google vs. Evil |url=https://www.wired.com/2003/01/google-10/ |magazine=[[Wired (magazine)|Wired]] |access-date=August 24, 2019}}</ref><ref>{{Cite news |last=D'Onfro |first=Jillian |date=February 13, 2016 |title=How a billionaire who wrote Google's original code created a robot revolution |work=[[Business Insider]] |url=https://www.businessinsider.com/a-look-back-at-willow-garage-2016-2 |access-date=August 24, 2019 |archive-date=August 24, 2019 |archive-url=https://web.archive.org/web/20190824075346/https://www.businessinsider.com/a-look-back-at-willow-garage-2016-2 |url-status=live }}</ref> In 2011, Google introduced "[[Google Voice Search]]" to search for spoken, rather than typed, words.<ref name="Official announcement">Google (Tue June 14, 2011) [https://www.google.com/insidesearch/press.html#blog Official announcement] {{Webarchive|url=https://web.archive.org/web/20200731120836/https://www.google.com/search/about/#blog |date=July 31, 2020 }}</ref> In 2012, Google introduced a [[semantic search]] feature named [[Knowledge Graph]].

===History===


== Search indexing ==
Google began as a research project in early [[1996]] by [[Larry Page]] and [[Sergey Brin]], two [[Stanford University|Stanford]] [[Ph.D.]] students who developed the theory that a search engine based on a mathematical analysis of the relationships between websites would produce better results than the basic techniques then in use. It was originally nicknamed '''BackRub''' because the system checked [[backlinks]] to estimate a site's importance.

Despite Google search's immense index, sources generally assume that Google is only indexing less than 5% of the total Internet, with the rest belonging to the [[deep web]], inaccessible through its search tools.<ref name="Seeker indexing" /><ref>{{Cite web |last=Rosen |first=JJ |date=May 3, 2014 |title=The Internet you can't Google |url=http://www.tennessean.com/story/money/tech/2014/05/02/jj-rosen-popular-search-engines-skim-surface/8636081/ |access-date=December 9, 2017 |website=[[The Tennessean]] |publisher=[[Gannett Company]]}}</ref><ref>{{Cite journal |last1=Sherman |first1=Chris |last2=Price |first2=Gary |date=May 22, 2008 |title=The Invisible Web: Uncovering Sources Search Engines Can't See |publisher=[[University of Illinois at Urbana–Champaign]] |website=Illinois Digital Environment for Access to Learning and Scholarship |hdl=2142/8528}}</ref>
Convinced that the pages with the most links to them from other highly relevant webpages must be the most relevant ones, Page and Brin decided to test their thesis as part of their studies, and laid the foundation for their search engine. They formally founded their company, '''Google Inc.''', on [[September 7]], [[1998]] in [[Menlo Park, California]] in a friend's garage. The company moved to more spacious headquarters in February 1999 in [[Palo Alto, California|Palo Alto]] before finally moving to the "Googleplex" later that year.


In 2012, Google changed its search indexing tools to demote sites that had been accused of [[Online piracy|piracy]].<ref>{{Cite magazine |last=Albanesius |first=Chloe |date=August 10, 2012 |title=Google to Demote Sites With 'High Number' of Copyright Complaints |url=http://uk.pcmag.com/search-products/61328/news/google-to-demote-sites-with-high-number-of-copyright-complai |access-date=December 9, 2017 |magazine=[[PC Magazine]] |publisher=[[Ziff Davis]]}}</ref> In October 2016, Gary Illyes, a webmaster trends analyst with Google, announced that the search engine would be making a separate, primary web index dedicated for mobile devices, with a secondary, less up-to-date index for desktop use. The change was a response to the continued growth in mobile usage, and a push for web developers to adopt a mobile-friendly version of their websites.<ref>{{Cite news |last=Schwartz |first=Barry |date=October 13, 2016 |title=Within months, Google to divide its index, giving mobile users better & fresher content |work=Search Engine Land |url=https://searchengineland.com/google-divide-index-giving-mobile-users-better-fresher-content-261037 |access-date=December 9, 2017 |archive-date=December 9, 2017 |archive-url=https://web.archive.org/web/20171209204052/https://searchengineland.com/google-divide-index-giving-mobile-users-better-fresher-content-261037 |url-status=live }}</ref><ref>{{Cite web |last=Roberts |first=Hannah |date=October 27, 2016 |title=Google is splitting its search index to target 'stripped down' mobile websites |url=http://nordic.businessinsider.com/google-changing-index-splitting-into-desktop-and-mobile-2016-10 |access-date=December 9, 2017 |website=[[Business Insider]] |publisher=[[Axel Springer SE]] |archive-date=December 9, 2017 |archive-url=https://web.archive.org/web/20171209204115/http://nordic.businessinsider.com/google-changing-index-splitting-into-desktop-and-mobile-2016-10 |url-status=live }}</ref> In December 2017, Google began rolling out the change, having already done so for multiple websites.<ref>{{Cite web |last=Perez |first=Sarah |date=December 20, 2017 |title=Google's mobile-first search index has rolled out to a handful of sites |url=https://techcrunch.com/2017/12/20/googles-mobile-first-search-index-has-rolled-out-to-a-handful-of-sites/ |access-date=December 21, 2017 |website=[[TechCrunch]] |publisher=[[Oath Inc.]] |archive-date=December 20, 2017 |archive-url=https://web.archive.org/web/20171220160026/https://techcrunch.com/2017/12/20/googles-mobile-first-search-index-has-rolled-out-to-a-handful-of-sites/ |url-status=live }}</ref>
Google gained a following among [[Internet]] users for its simple, clean design and relevant search results. [[Advertisement]]s were sold by the [[keyword]] so that they would be more relevant to the end user, and the ads were text-based in order to keep page design uncluttered and fast-loading. The concept of selling Keyword advertising was originally pioneered by [http://www.content.overture.com/d/USm/about/news/mile.jhtml Overture], formally Goto.com. While many of its [[dot-com]] siblings went under, Google quietly rose in stature while turning a profit.


=== "Caffeine" search architecture upgrade ===
In February [[2003]], Google acquired [[Pyra Labs]], owner of [[Blogger]], a pioneering and leading [[weblog]]-hosting website. The acquisition seemed inconsistent with the general mission of Google. However, the move secured the company's ability to utilize information gleaned from [[blog]] postings to improve the speed and relevance of articles contained in Google News.
In August 2009, Google invited web developers to test a new search architecture, codenamed "Caffeine", and give their feedback. The new architecture provided no visual differences in the user interface, but added significant speed improvements and a new "under-the-hood" indexing infrastructure. The move was interpreted in some quarters as a response to [[Microsoft]]'s recent release of an upgraded version of its own search service, renamed [[Bing (search engine)|Bing]], as well as the launch of [[Wolfram Alpha]], a new search engine based on "computational knowledge".<ref>{{Cite news |last=Barnett |first=Emma |date=August 11, 2009 |title=Google reveals caffeine: a new faster search engine |work=[[The Daily Telegraph]] |url=https://www.telegraph.co.uk/technology/google/6009176/Google-reveals-caffeine-a-new-faster-search-engine.html |url-status=live |url-access=subscription |access-date=December 9, 2017 |archive-url=https://ghostarchive.org/archive/20220110/https://www.telegraph.co.uk/technology/google/6009176/Google-reveals-caffeine-a-new-faster-search-engine.html |archive-date=January 10, 2022}}{{cbignore}}</ref><ref>{{Cite web |last=Fox |first=Vanessa |date=August 10, 2009 |title=Google Caffeine: Google's New Search Engine Index |url=https://searchengineland.com/caffeine-googles-new-search-index-23823 |access-date=December 9, 2017 |website=[[Search Engine Land]] |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210071617/https://searchengineland.com/caffeine-googles-new-search-index-23823 |url-status=live }}</ref> Google announced completion of "Caffeine" on June 8, 2010, claiming 50% fresher results due to continuous updating of its index.<ref>{{Cite web |last=Fox |first=Vanessa |date=June 8, 2010 |title=Google's New Indexing Infrastructure "Caffeine" Now Live |url=https://searchengineland.com/googles-new-indexing-infrastructure-caffeine-now-live-43891 |access-date=December 9, 2017 |website=[[Search Engine Land]] |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210071639/https://searchengineland.com/googles-new-indexing-infrastructure-caffeine-now-live-43891 |url-status=live }}</ref>


With "Caffeine", Google moved its back-end indexing system away from [[MapReduce]] and onto [[Bigtable]], the company's distributed database platform.<ref>{{Cite web |last=Metz |first=Cade |date=September 9, 2010 |title=Google search index splits with MapReduce |url=https://www.theregister.co.uk/2010/09/09/google_caffeine_explained |access-date=December 9, 2017 |website=[[The Register]] |publisher=Situation Publishing |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210020001/https://www.theregister.co.uk/2010/09/09/google_caffeine_explained |url-status=live }}</ref><ref>{{Cite web |last=Metz |first=Cade |date=August 14, 2009 |title=Google Caffeine: What it really is |url=https://www.theregister.co.uk/2009/08/14/google_caffeine_truth/ |access-date=December 9, 2017 |website=[[The Register]] |publisher=Situation Publishing |archive-date=December 23, 2017 |archive-url=https://web.archive.org/web/20171223224328/http://www.theregister.co.uk/2009/08/14/google_caffeine_truth |url-status=live }}</ref>
At its peak in early 2004, Google handled upwards of 80% of all search requests on the world wide web through its website and clients like [[Yahoo!]], [[AOL]], and [[CNN]]. [http://www.onestat.com/html/aboutus_pressbox21.html] Google's share fell in [[February 2004]] when Yahoo! dropped Google's search technology in order to deliver independent results.


=== "Medic" search algorithm update ===
Google's [[code of conduct]] is ''Don't be evil.'' Their site includes humorous features such as [http://www.google.com/holidaylogos.html cartoon modifications] of their logo for special occasions, the option to display the site in fictional or humorous languages such as [[klingon]], and [[April Fool's]] jokes about the company.
In August 2018, [[Danny Sullivan (technologist)|Danny Sullivan]] from Google announced a broad core algorithm update. As per current analysis done by the industry leaders Search Engine Watch and Search Engine Land, the update was to drop down the medical and health-related websites that were not user friendly and were not providing good user experience. This is why the industry experts named it "Medic".<ref>{{Cite web |last=Schwartz |first=Barry |date=August 9, 2018 |title=Google's Aug. 1 core algorithm update: Who did it impact, and how much |url=https://searchengineland.com/googles-august-first-core-algorithm-update-who-did-it-impact-and-how-much-303538 |website=[[Search Engine Land]] |access-date=August 23, 2018 |archive-date=August 23, 2018 |archive-url=https://web.archive.org/web/20180823174248/https://searchengineland.com/googles-august-first-core-algorithm-update-who-did-it-impact-and-how-much-303538 |url-status=live }}</ref>


Google reserves very high standards for YMYL (Your Money or Your Life) pages. This is because misinformation can affect users financially, physically, or emotionally. Therefore, the update targeted particularly those YMYL pages that have low-quality content and misinformation. This resulted in the algorithm targeting health and medical-related websites more than others. However, many other websites from other industries were also negatively affected.<ref>{{Cite web |title=Google Medic Update: Google's Core Search Update Had Big Impact On Health/Medical Sites |url=https://www.seroundtable.com/google-medic-update-26177.html |access-date=March 11, 2019 |website=seroundtable.com |date=August 8, 2018 |archive-date=March 21, 2019 |archive-url=https://web.archive.org/web/20190321033704/https://www.seroundtable.com/google-medic-update-26177.html |url-status=live }}</ref>
===Financing and IPO===


== Search results ==
Google's major investors are the venture capital firms [[Kleiner Perkins Caufield & Byers]] and [[Sequoia Capital]]. In [[October 2003]], while discussing a possible [[IPO]] (Initial Public Offering of shares), the company was approached by [[Microsoft]] about a possible partnership or [[merger]]; no such deal ever materialized.


=== Ranking of results ===
In [[January 2004]], Google announced the hiring of [[Morgan Stanley]] and [[Goldman Sachs Group]] to arrange an IPO. That IPO (one of the most anticipated in history) might raise as much as $4 billion. According to a banker involved in the transaction, the deal would produce for Google a [[market capitalization]] of as much as $12 billion.


In 2013 the [[European Commission]] found that Google Search favored Google's own products, instead of the best result for consumers' needs.<ref>{{Cite web |last1=Barker |first1=Alex |last2=McCarthy |first2=Bede |date=April 9, 2013 |title=Google favours 'in-house' search results |url=http://www.ft.com/intl/cms/s/0/c308b656-a124-11e2-bae1-00144feabdc0.html |archive-url=https://ghostarchive.org/archive/20221210/http://www.ft.com/intl/cms/s/0/c308b656-a124-11e2-bae1-00144feabdc0.html |archive-date=December 10, 2022 |url-access=subscription |url-status=live |access-date=January 26, 2014 |website=Financial Times}}</ref> In February 2015 Google announced a major change to its mobile search [[algorithm]] which would favor mobile friendly over other [[websites]]. Nearly 60% of Google [[online traffic|searches]] come from mobile phones. Google says it wants users to have access to premium quality [[websites]]. Those websites which lack a mobile-friendly [[Interface (computing)|interface]] would be ranked lower and it is expected that this update will cause a shake-up of [[Page rank|ranks]]. Businesses who fail to update their [[websites]] accordingly could see a dip in their regular websites traffic.<ref>{{Cite web |last=D'Onfro |first=Jillian |date=April 19, 2015 |title=Google is making a giant change this week that could crush millions of small businesses |url=http://www.businessinsider.com/google-mobilegeddon-2015-4 |website=Business Insider |access-date=November 5, 2016 |archive-date=October 7, 2016 |archive-url=https://web.archive.org/web/20161007045504/http://www.businessinsider.com/google-mobilegeddon-2015-4 |url-status=live }}</ref>
On [[April 29]], [[2004]], Google filed an [[S-1 form]] with the [[Securities and Exchange Commission]] for an [[IPO]] to raise as much as [[United States dollar|USD]] $2,718,281,828 (with a touch of [[e (mathematical constant)#Humorous_use_of_e|mathematical humor]] in the exact amount). The filing revealed that Google turned a profit every year since 2001 and earned a profit of $105.6 million on revenues of $961.8 million during 2003.


=== PageRank ===
Although the offer has been reported to be open to the public, a simple search of google's website, such as [http://www.google.com/search?num=100&hl=en&lr=&ie=UTF-8&q=buying+shares+in+google+site%3Agoogle.com&btnG=Search buying shares in google site:google.com] does not reveal any information.
{{Main|PageRank}}
<!-- If you can formulate a search that does, please put it here. -->


Google's rise was largely due to a patented [[algorithm]] called PageRank which helps rank web pages that match a given search string.<ref>{{Cite journal |last1=Brin |first1=S. |author-link=Sergey Brin |last2=Page |first2=L. |author-link2=Larry Page |year=1998 |title=The anatomy of a large-scale hypertextual Web search engine |url=http://infolab.stanford.edu/pub/papers/google.pdf |archive-url=https://web.archive.org/web/20061108120131/http://infolab.stanford.edu/pub/papers/google.pdf |archive-date=2006-11-08 |url-status=live |journal=Computer Networks and ISDN Systems |volume=30 |issue=1–7 |pages=107–117 |citeseerx=10.1.1.115.5930 |doi=10.1016/S0169-7552(98)00110-X |s2cid=7587743 |issn=0169-7552}}</ref> When Google was a Stanford research project, it was nicknamed [[BackRub]] because the technology checks [[backlinks]] to determine a site's importance. Other keyword-based methods to rank search results, used by many search engines that were once more popular than Google, would check how often the search terms occurred in a page, or how strongly associated the search terms were within each resulting page. The PageRank algorithm instead analyzes human-generated [[hyperlink|links]] assuming that web pages linked from many important pages are also important. The algorithm computes a [[recursion|recursive]] score for pages, based on the weighted sum of other pages linking to them. PageRank is thought to [[correlation|correlate]] well with human concepts of importance. In addition to PageRank, Google, over the years, has added many other secret criteria for determining the ranking of resulting pages. This is reported to comprise over 250 different indicators,<ref>{{Cite web |title=Corporate Information: Technology Overview |url=https://www.google.com/corporate/tech.html |access-date=November 15, 2009 |archive-date=February 10, 2010 |archive-url=https://web.archive.org/web/20100210175913/http://www.google.com/corporate/tech.html |url-status=live }}</ref><ref>{{Cite magazine |last=Levy |first=Steven |date=February 22, 2010 |title=Exclusive: How Google's Algorithm Rules the Web |url=https://www.wired.com/magazine/2010/02/ff_google_algorithm/ |magazine=Wired |publisher=Wired.com |volume=17 |issue=12 |archive-url=https://web.archive.org/web/20110416062117/http://www.wired.com/magazine/2010/02/ff_google_algorithm/ |archive-date=April 16, 2011}}</ref> the specifics of which are kept secret to avoid difficulties created by scammers and help Google maintain an edge over its competitors globally.

PageRank was influenced by a similar page-ranking and site-scoring algorithm earlier used for [[RankDex]], developed by [[Robin Li]] in 1996. Larry Page's patent for PageRank filed in 1998 includes a citation to Li's earlier patent.

===Etymology===


In a potential hint of Google's future direction of their Search algorithm, Google's then chief executive [[Eric Schmidt]], said in a 2007 interview with the ''[[Financial Times]]'': "The goal is to enable Google users to be able to ask the question such as 'What shall I do tomorrow?' and 'What job shall I take?{{'"}}.<ref>[http://www.ft.com/cms/s/2/c3e49548-088e-11dc-b11e-000b5df10621,dwp_uuid=e8477cc4-c820-11db-b0dc-000b5df10621.html "Google's goal: to organize your daily life"] {{Webarchive|url=https://web.archive.org/web/20111019004110/http://www.ft.com/cms/s/2/c3e49548-088e-11dc-b11e-000b5df10621,dwp_uuid=e8477cc4-c820-11db-b0dc-000b5df10621.html |date=October 19, 2011 }}. ''[[Financial Times]]''.</ref> Schmidt reaffirmed this during a 2010 interview with ''[[The Wall Street Journal]]'': "I actually think most people don't want Google to answer their questions, they want Google to tell them what they should be doing next."<ref>[https://www.wsj.com/articles/SB10001424052748704901104575423294099527212 "Google and the Search for the Future"] {{Webarchive|url=https://web.archive.org/web/20170730120818/https://www.wsj.com/articles/SB10001424052748704901104575423294099527212 |date=July 30, 2017 }}.

The name "Google" is a play on the word ''[[googol]]'', which was coined by [[Milton Sirotta]], nephew of [[United States|U.S.]] [[mathematician]] [[Edward Kasner]] in [[1938]], to refer to the number represented by 1 followed by a hundred zeros. Google's use of the term reflects the company's mission to organize the immense amount of information available on the Web.
It was coined by Andy Bechtolsheim who made out a check to "Google Inc."

=== Google optimization ===
{{Main|Search engine optimization}}


Because Google is the most popular [[Web search engine|search engine]], many [[webmaster]]s attempt to influence their website's Google rankings. An industry of consultants has arisen to help websites increase their rankings on Google and other search engines. This field, called search engine optimization, attempts to discern patterns in search engine listings, and then develop a methodology for improving rankings to draw more searchers to their clients' sites. Search engine optimization encompasses both "on page" factors (like body copy, title elements, H1 heading elements and image [[alt attribute]] values) and Off Page Optimization factors (like [[anchor text]] and PageRank). The general idea is to affect Google's relevance algorithm by incorporating the keywords being targeted in various places "on page", in particular the title element and the body copy (note: the higher up in the page, presumably the better its keyword prominence and thus the ranking). Too many occurrences of the keyword, however, cause the page to look suspect to Google's spam checking algorithms. Google has published guidelines for website owners who would like to raise their rankings when using legitimate optimization consultants.<ref>{{Cite web |title=Google Webmaster Guidelines |url=https://www.google.com/webmasters/guidelines.html |access-date=November 15, 2009 |archive-date=January 9, 2009 |archive-url=https://web.archive.org/web/20090109073316/http://www.google.com./webmasters/guidelines.html |url-status=live }}</ref> It has been hypothesized, and, allegedly, is the opinion of the owner of one business about which there have been numerous complaints, that negative publicity, for example, numerous consumer complaints, may serve as well to elevate page rank on Google Search as favorable comments.<ref>{{Cite news |last=Segal |first=David |date=November 26, 2010 |title=A Bully Finds a Pulpit on the Web |work=[[The New York Times]] |url=https://www.nytimes.com/2010/11/28/business/28borker.html |url-status=live |url-access=limited |access-date=November 27, 2010 |archive-url=https://ghostarchive.org/archive/20220102/https://www.nytimes.com/2010/11/28/business/28borker.html |archive-date=January 2, 2022}}{{cbignore}}</ref> The particular problem addressed in ''[[The New York Times]]'' article, which involved [[DecorMyEyes]], was addressed shortly thereafter by an undisclosed fix in the Google algorithm. According to Google, it was not the frequently published consumer complaints about DecorMyEyes which resulted in the high ranking but mentions on news websites of events which affected the firm such as legal actions against it. [[Google Search Console]] helps to check for websites that use duplicate or copyright content.<ref>{{Cite web |title=Blogspot.com |url=http://googleblog.blogspot.com/2010/12/being-bad-to-your-customers-is-bad-for.html |access-date=August 4, 2012 |publisher=Googleblog.blogspot.com |archive-date=October 19, 2012 |archive-url=https://web.archive.org/web/20121019115129/http://googleblog.blogspot.com/2010/12/being-bad-to-your-customers-is-bad-for.html |url-status=live }}</ref>
A number of organizations (most controversially the [[Church of Scientology]]) have used the [[Digital Millennium Copyright Act]] to demand that Google remove references to allegedly [[copyright|copyrighted]] material on other sites. Google typically handles this by removing the link as requested and including a link to the complaint in the search results. There have also been complaints that the "Google cache" feature violates copyright. However, the consensus seems to be that caching is a normal part of the functionality of the web, and that [[HTTP]] provides adequate mechanisms for requesting that caching be disabled (which Google respects; it also honors the [[robots.txt]] file which is a mechanism to allow the owners of a site to request that part or all of their site not be included in search engine listings).


=== "Hummingbird" search algorithm upgrade ===
In [[2002]], news reports surfaced that the Google search engine had been banned in [[China]]. A [[mirror site]] (in all respects, including mirrored text) called ''elgooG'' proved useful to get around the ban. The ban was later lifted, and reports indicated that it was not Google itself that was targeted. Rather, Google's feature of a cached version of a website would allow Chinese users to circumvent any ban of a website itself, merely by visiting the cache instead. There is also a dynamic Google mirror working as a [[proxy server]] at <nowiki>http://www.zensur.freerk.com/google/ </nowiki>.
{{Main|Google Hummingbird}}

=== Search results quality ===
Google's efforts to refine its database has led to some legal controversy, drawing a lawsuit in [[October 2002]] from a company, [[SearchKing]], that sought to sell advertisements on pages with inflated Google rankings. In its defense, Google said that its rankings are its constitutionally protected opinions of the web sites that it lists. A judge threw out SearchKing's lawsuit in mid-2003 on precisely these grounds.


In the 2020s, observers reported on a perceived declining quality of search results found in Google Search.<ref>{{cite web|first1=Dmitri|last1=Brereton|access-date=2023-11-07|title=Google Search Is Dying|url=https://dkb.blog/p/google-search-is-dying|website=dkb.blog}}</ref>
In late 2003 and early 2004, there were persistent rumors that Google would be sued by the [[SCO Group]] over its use of the [[Linux]] operating system, in conjunction with SCO's [[SCO v. IBM|lawsuit against IBM]] over the ownership of [[intellectual property]] rights relating to Linux.

Google employs [[server farm]]s of [[Linux|GNU/Linux]] computers around the world to answer search requests and to index the web. The server farms are built using a [[shared nothing architecture]]. The indexing is performed by a program ("Googlebot") which periodically requests new copies of the web pages it already knows about. The more often a page updates, the more often Googlebot will visit. The links in these pages are examined to discover new pages to be added to its [[database]]. The index database and web page cache is several [[terabyte]]s in size.


=== Universal search ===
The exact size and whereabouts of the physical machines in the google search engine is unknown, and official figures remain intentionally vague. In [[John Hennessy]] and [[David A. Patterson|David Patterson]]'s ''Computer Architecture: A Quantitative Approach'', the [[server farm]] [[cluster computing|cluster]] forming the Google "search farm" would in the year 2000 have consisted of about 6000 processors, 12000 common [[Advanced Technology Attachment|IDE]]-disks (2 per machine, and one machine per processor), at four sites: two in [[Silicon Valley]] and two in [[Virginia]].
"Universal search" was launched by Google on May 16, 2007, as an idea that merged the results from different kinds of search types into one. Prior to Universal search, a standard Google search would consist of links only to websites. Universal search, however, incorporates a wide variety of sources, including websites, news, pictures, maps, blogs, videos, and more, all shown on the same search results page.<ref>{{Cite web |last=Marshall |first=Matt |date=May 16, 2007 |title=Google's move to "universal search" |url=https://venturebeat.com/2007/05/16/googles-move-to-universal-search/ |access-date=December 9, 2017 |website=[[VentureBeat]] |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210071603/https://venturebeat.com/2007/05/16/googles-move-to-universal-search/ |url-status=live }}</ref><ref>{{Cite web |last=Sullivan |first=Danny |date=May 16, 2007 |title=Google Launches "Universal Search" & Blended Results |url=https://searchengineland.com/google-20-google-universal-search-11232 |access-date=December 9, 2017 |website=[[Search Engine Land]] |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210071528/https://searchengineland.com/google-20-google-universal-search-11232 |url-status=live }}</ref> [[Marissa Mayer]], then-vice president of search products and user experience, described the goal of Universal search as "we're attempting to break down the walls that traditionally separated our various search properties and integrate the vast amounts of information available into one simple set of search results.<ref>{{Cite web |last=Mayer |first=Marissa |author-link=Marissa Mayer |date=May 16, 2007 |title=Universal search: The best answer is still the best answer |url=https://googleblog.blogspot.no/2007/05/universal-search-best-answer-is-still.html |access-date=December 9, 2017 |website=Official Google Blog |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210071719/https://googleblog.blogspot.no/2007/05/universal-search-best-answer-is-still.html |url-status=live }}</ref>


In June 2017, Google expanded its search results to cover available job listings. The data is aggregated from various major job boards and collected by analyzing company homepages.

Each site had an OC 48 (2488 Mbps, see [[broadband Internet access]] article) connection to the Internet and an OC 12 (622 Mbps) connections to other Google sites. The connections are routed through a [[Cisco 12000]] [[network switch]] and split by two [[Foundry Networks]] [[BigIron 8000]] [[ethernet switch]]es dividing the traffic onto 4 x 1 Gbps lines connecting up to 64 racks, with 40 machines and an [[Hewlett Packard|HP]] Ethernet switch on both back and flip side, so that a rack would fit 80 machines and two HP switches.


=== Rich snippets ===
Based on the Google IPO S-1 form released in [[April 2004]], Tristan Louis, the Vice President of application development for the Internet unit of a large financial firm, estimated the current server farm to contain something like the following [http://www.tnl.net/blog/entry/How_many_Google_machines]:
In May 2009, Google announced that they would be parsing website [[microformat]]s to populate search result pages with "Rich snippets". Such snippets include additional details about results, such as displaying reviews for restaurants and social media accounts for individuals.<ref>{{Cite web |last=Fox |first=Vanessa |date=May 12, 2009 |title=Google Search Now Supports Microformats and Adds "Rich Snippets" to Search Results |url=https://searchengineland.com/google-search-now-supports-microformats-and-adds-rich-snippets-to-search-results-19055 |access-date=December 9, 2017 |website=[[Search Engine Land]] |archive-date=December 9, 2017 |archive-url=https://web.archive.org/web/20171209204028/https://searchengineland.com/google-search-now-supports-microformats-and-adds-rich-snippets-to-search-results-19055 |url-status=live }}</ref>

===PageRank and indexing===
=== Personal tab ===
In May 2017, Google enabled a new "Personal" tab in Google Search, letting users search for content in their Google accounts' various services, including email messages from [[Gmail]] and photos from [[Google Photos]].<ref>{{Cite web |last=Gartenberg |first=Chaim |date=May 26, 2017 |title=Google adds new Personal tab to search results to show Gmail and Photos content |url=https://www.theverge.com/2017/5/26/15701778/google-personal-tab-search-results-gmail-photos-images-maps-news-filter |access-date=May 27, 2017 |website=[[The Verge]] |publisher=[[Vox Media]] |archive-date=May 26, 2017 |archive-url=https://web.archive.org/web/20170526215945/https://www.theverge.com/2017/5/26/15701778/google-personal-tab-search-results-gmail-photos-images-maps-news-filter |url-status=live }}</ref><ref>{{Cite web |last=Westenberg |first=Jimmy |date=May 28, 2017 |title=New Personal tab in Google Search will show results from Photos, Gmail, and more |url=https://www.androidauthority.com/google-search-personal-results-775676/ |access-date=December 15, 2017 |website=Android Authority |archive-date=December 15, 2017 |archive-url=https://web.archive.org/web/20171215221410/https://www.androidauthority.com/google-search-personal-results-775676/ |url-status=live }}</ref>


=== Google Discover ===
Google uses an [[algorithm]] called [[PageRank]] to rank web pages that match a given search string. The PageRank algorithm computes a recursive figure of merit for web pages, based on the weighted sum of the PageRanks of the pages linking to them. The PageRank thus derives from human-generated links, and correlates well with human concepts of importance. Previous keyword-based methods of ranking search results, used by many search engines that were once more popular than Google, would rank pages by how often the search terms occurred in the page, or how strongly associated the search terms were within each resulting page. In addition to PageRank, Google also uses other secret criteria for determining the ranking of pages on result lists.
Google Discover, previously known as Google Feed, is a personalized stream of articles, videos, and other news-related content. The feed contains a "mix of cards" which show topics of interest based on users' interactions with Google, or topics they choose to follow directly.<ref name=":0">{{Cite news |last=Bell |first=Karissa |title=Google is using your entire search history to create a personalized news feed |work=Mashable |url=https://mashable.com/2017/07/19/google-search-feed/ |access-date=May 22, 2018 |archive-date=May 23, 2018 |archive-url=https://web.archive.org/web/20180523101022/https://mashable.com/2017/07/19/google-search-feed/ |url-status=live }}</ref> Cards include, "links to news stories, YouTube videos, sports scores, recipes, and other content based on what [Google] determined you're most likely to be interested in at that particular moment."<ref name=":0" /> Users can also tell Google they're not interested in certain topics to avoid seeing future updates.


Google Discover launched in December 2016<ref>{{Cite news |title=Google is putting a news feed in Android's home screen |work=The Verge |url=https://www.theverge.com/2016/12/6/13852402/google-news-feed-search-app-android |access-date=May 22, 2018 |archive-date=September 13, 2018 |archive-url=https://web.archive.org/web/20180913112717/https://www.theverge.com/2016/12/6/13852402/google-news-feed-search-app-android |url-status=live }}</ref> and received a major update in July 2017.<ref>{{Cite news |last=Larson |first=Selena |title=The Google app feed is about to get more personal |work=CNNMoney |url=https://money.cnn.com/2017/07/19/technology/business/google-feed-new-personalized-fact-check/index.html |access-date=May 22, 2018 |archive-date=May 23, 2018 |archive-url=https://web.archive.org/web/20180523095808/http://money.cnn.com/2017/07/19/technology/business/google-feed-new-personalized-fact-check/index.html |url-status=live }}</ref> Another major update was released in September 2018, which renamed the app from Google Feed to Google Discover, updated the design, and adding more features.<ref>{{Cite news |title=Introducing Google Discover |work=The Keyword Google |url=https://blog.google/products/search/introducing-google-discover/ |access-date=July 14, 2021 |archive-date=July 16, 2021 |archive-url=https://web.archive.org/web/20210716170905/http://www.blog.google/products/search/introducing-google-discover/ |url-status=live }}</ref>
Google not only indexes and caches HTML-files but also 12 other file types, including [[Portable Document Format|.PDF]], [[txt|.txt]], [[Word document|.doc]], and [[Excel spreadsheet|.xls]]. Except in the case of text files, the cached version is a conversion to HTML. Hence Google allows reading these files even without having the corresponding program such as Word or Excel.


Discover can be found on a tab in the Google app and by swiping left on the home screen of certain Android devices. As of 2019, Google will not allow [[political campaign]]s worldwide to target their advertisement to people to make them vote.<ref>{{Cite news |last=Lee |first=Dave |date=November 21, 2019 |title=Google to restrict political adverts worldwide |language=en-GB |url=https://www.bbc.com/news/technology-50498166 |access-date=November 21, 2019 |archive-date=November 21, 2019 |archive-url=https://web.archive.org/web/20191121014728/https://www.bbc.com/news/technology-50498166 |url-status=live }}</ref>
Users can customize the search engine somewhat. They can set a default language, use "SafeSearch" filtering technology, and set the number of results shown on each page. Google has been criticized for placing long-term [[HTTP cookie|cookies]] on users' machines to store these preferences, a tactic which also enables them to track a user's search terms over time. For any query (of which only the 10 first keywords are taken into account), up to the first 1000 results can be shown with a maximum of 100 displayed per page.


=== Search Generative Experience ===
Despite its immense index, there is also a considerable amount of data in databases which are accessible from websites by means of queries, but not by links. This so-called [[deep web]] is not covered by Google and contains e.g. [[catalog]]ues of [[library|libraries]], official [[legislative]] documents of governments, [[phone book]]s, etc.
At the 2023 [[Google I/O]] event in May, Google unveiled Search Generative Experience (SGE), an experimental feature in Google Search available through [[Google Labs]] which produces [[AI-generated]] summaries in response to search prompts.<ref>{{Cite web |last=Pierce |first=David |date=May 10, 2023 |title=The AI takeover of Google Search starts now |url=https://www.theverge.com/2023/5/10/23717120/google-search-ai-results-generated-experience-io |url-status=live |archive-url=https://web.archive.org/web/20230510175211/https://www.theverge.com/2023/5/10/23717120/google-search-ai-results-generated-experience-io |archive-date=May 10, 2023 |access-date=September 12, 2023 |website=[[The Verge]]}}</ref> This was part of Google's wider efforts to counter the unprecedented rise of generative AI technology, ushered by [[OpenAI]]'s launch of [[ChatGPT]], which sent Google executives to a panic due to its potential threat to Google Search.<ref>{{Cite magazine |last=Levy |first=Steven |author-link=Steven Levy |date=September 11, 2023 |title=Sundar Pichai on Google;s AI, Microsoft's AI, OpenAI, and ...

==="Google dance" and optimization===


In late June 2011, Google introduced a new look to the Google home page in order to boost the use of the Google+ social tools.<ref>{{Cite web |last=Beato |first=Augusto |title=Google Redesign Backs Social Effort |url=http://www.portlandseo.net/google-redesign-backs-social-effort/ |access-date=July 1, 2011 |website=Portland SEO |archive-date=December 1, 2017 |archive-url=https://web.archive.org/web/20171201182305/http://www.portlandseo.net/google-redesign-backs-social-effort/ |url-status=live }}</ref>
Since Google is the most popular search engine, many [[webmaster]]s have become eager to follow and to explain changes to the rankings of their websites. A new industry of consultants has arisen to help websites raise their rankings on Google and on other search engines. This field, called [[search engine optimization]], attempts to discern patterns in search engine listings, and then develop a methodology for increasing rankings.


One of the major changes was replacing the classic navigation bar with a black one. Google's digital creative director Chris Wiggins explains: "We're working on a project to bring you a new and improved Google experience, and over the next few months, you'll continue to see more updates to our look and feel."<ref>{{Cite news |date=June 29, 2011 |title=Google redesigns its homepage |work=[[Los Angeles Times]] |url=http://latimesblogs.latimes.com/technology/2011/06/google-redesigns-its-homepage-with-new-black-bar-up-top-google-social-network.html |access-date=August 4, 2012 |archive-date=January 21, 2013 |archive-url=https://web.archive.org/web/20130121022830/http://latimesblogs.latimes.com/technology/2011/06/google-redesigns-its-homepage-with-new-black-bar-up-top-google-social-network.html |url-status=live }}</ref> The new navigation bar has been negatively received by a vocal minority.<ref>{{Cite web |title=Google support forum, one of many threads on being unable to switch off the black navigation bar |url=https://www.google.com/support/forum/p/Web+Search/thread?tid=7ddbf7a4c8fa04a9&hl=en |access-date=August 4, 2012 |archive-date=December 24, 2011 |archive-url=https://web.archive.org/web/20111224132612/http://www.google.com/support/forum/p/Web+Search/thread?tid=7ddbf7a4c8fa04a9&hl=en |url-status=live }}</ref>
One technique commonly used is [[google bomb]]ing in which many sites link to another site through a particular word, in order to give the site a high ranking when the word is searched for.


In November 2013, Google started testing yellow labels for advertisements displayed in search results, to improve user experience. The new labels, highlighted in yellow color, and aligned to the left of each sponsored link help users differentiate between organic and sponsored results.<ref>{{Cite web |title=Google ads: The wolf is out of the lamb's skin |url=http://www.techmw.com/google-ads-wolf-lambs-skin/ |access-date=December 2, 2013 |publisher=www.techmw.com |archive-date=December 2, 2013 |archive-url=https://web.archive.org/web/20131202081946/http://www.techmw.com/google-ads-wolf-lambs-skin/ |url-status=live }}</ref>
Forums can be found on the web where phenomena such as the "Google dance" are discussed. The Google dance is a period of a few days towards the end of a month when Google updates its database and ranking algorithms. Changes to the database can be observed by examining the number of results to a particular page such as "link:www.yahoo.com".


On December 15, 2016, Google rolled out a new desktop search interface that mimics their modular mobile user interface. The mobile design consists of a tabular design that highlights search features in boxes. and works by imitating the desktop Knowledge Graph real estate, which appears in the right-hand rail of the search engine result page, these featured elements frequently feature Twitter carousels, People Also Search For, and Top Stories (vertical and horizontal design) modules. The Local Pack and Answer Box were two of the original features of the Google [[search engine results page|SERP]] that were primarily showcased in this manner, but this new layout creates a previously unseen level of design consistency for Google results.<ref name="ab">{{Cite news |last=Schwartz, Barry |date=December 6, 2016 |title=Google begins rolling out a new desktop search user interface |work=Search Engine Land |agency=blogspot |url=http://searchengineland.com/google-begins-rolling-new-desktop-search-user-interface-264889 |access-date=December 6, 2016 |archive-date=December 7, 2016 |archive-url=https://web.archive.org/web/20161207142651/http://searchengineland.com/google-begins-rolling-new-desktop-search-user-interface-264889 |url-status=live }}</ref>
During the dance period, a site's ranking may change dramatically over a short period of time and different Google servers (e.g., www.google.com, www2.google.com, www3.google.com, www.google.co.uk, www.google.com.au, etc.) may give different results for the same search. The dance period appears to coincide with the time at which the googlebot examines stable sites. Rapidly changing sites, highly ranked sites and news sites are examined more often, although apart from news. Only minor adjustments are made to rankings during most of the month. In some cases it may take two or three months before new pages appear in search results. The monthly searching, indexing and ranking cycle was replaced by a continuous rolling update in the summer of 2003. This change in the way Google updates significantly reduced the unstable results of the monthly update dance.


=== Smartphone apps ===
One of Google's chief challenges is that as its algorithms and results have gained the trust of web users, the profit to be gained by a commercial web site in subverting those results has increased dramatically. Some search engine optimization firms have attempted to inflate specific Google rankings by various artifices, and thereby draw more searchers to their clients' sites. Google has managed to weaken some of these attempts by reducing the ranking of sites Google knows to use them.

Google publishes a set of [http://www.google.com/webmasters/guidelines.html guidelines] for a website's owners who would like to raise their rankings when using legitimate optimization consultants.


In December 2017, Google released "Google Go", an app designed to enable use of Google Search on physically smaller and lower-spec devices in multiple languages. A Google blog post about designing "India-first" products and features explains that it is "tailor-made for the millions of people in [India and Indonesia] coming online for the first time".<ref>{{Cite web |date=December 5, 2017 |title=Google for India: Building India-first products and features |url=https://blog.google/technology/next-billion-users/building-india-first-products-and-features/ |access-date=February 5, 2022 |website=Google |language=en-us |archive-date=February 5, 2022 |archive-url=https://web.archive.org/web/20220205150826/https://blog.google/technology/next-billion-users/building-india-first-products-and-features/ |url-status=live }}</ref>
==Other Google services==
===Google Groups (Usenet) & Google Images===
Google maintains a usenet archive, called '''Google Groups''' (formerly an independent site known as [[DejaNews]]) and an image search function (called "Google Images"). The latter is based on the text on the page adjacent to the image, the image caption, etc. A small version of the images is cached to comply with [[fair use]] laws.

Google is currently testing a new version of its Groups service, which archives [[mailing list]]s in addition to usenet posts, using the same interface as Gmail (see below).

Google Search consists of a series of [[Website localization|localized websites]]. The largest of those, the [https://www.google.com/?safe=active&ssui=on google.com site], is the top most-visited website in the world.<ref name="alexarank">{{Cite web |title=Top 500 |url=https://www.alexa.com/topsites |publisher=[[Alexa Internet]] |access-date=November 8, 2020 |archive-date=February 3, 2021 |archive-url=https://web.archive.org/web/20210203120227/https://www.alexa.com/topsites |url-status=dead }}</ref> Some of its features include a definition link for most searches including dictionary words, the number of results you got on your search, links to other searches (e.g. for words that Google believes to be misspelled, it provides a link to the search results using its proposed spelling), the ability to filter results to a date range,<ref>{{Cite web |last=Perry |first=Alex |date=April 10, 2019 |title=Google makes it way easier to search by date |url=https://mashable.com/article/google-search-by-date |access-date=March 2, 2022 |website=Mashable |language=en |archive-date=March 2, 2022 |archive-url=https://web.archive.org/web/20220302195856/https://mashable.com/article/google-search-by-date |url-status=live }}</ref> and many more.
Google introduced a [[development stage|beta release]] of an automated [[news]] compilation service, "Google News" in [[April 2002]]. There are different versions of the aggregator for the languages [[English language|English]], [[German language|German]], [[French language|French]], [[Spanish language|Spanish]], and [[Italian language|Italian]]. To quell any charges of reporting bias, it is fully automated with no human editors.


=== Search syntax{{anchor|Google Advanced Search}} ===
The service covers the news articles that appeared within the past 30 days on news websites in the language concerned, from various countries; for the English language it covers about 4,500 sites, for the other languages less. It provides around the first 200 characters and links to the full article. Some of these websites require a subscription; in that case this is noted in the Google News summary of their articles.
Google search accepts queries as normal text, as well as individual keywords.<ref name="How to search">{{Cite web |title=How to search on Google |url=https://support.google.com/websearch/answer/134479 |access-date=December 9, 2017 |website=Google Search Help |archive-date=December 5, 2017 |archive-url=https://web.archive.org/web/20171205130532/https://support.google.com/websearch/answer/134479 |url-status=live }}</ref> It [[autocorrection|automatically corrects]] apparent misspellings by default (while offering to use the original spelling as a selectable alternative), and provides the same results regardless of capitalization.<ref name="How to search" /> For more customized results, one can use a wide variety of [[Operator (computer programming)|operators]], including, but not limited to:<ref>{{Cite web |title=Refine web searches |url=https://support.google.com/websearch/answer/2466433 |access-date=December 9, 2017 |website=Google Search Help |archive-date=October 11, 2017 |archive-url=https://web.archive.org/web/20171011040039/https://support.google.com/websearch/answer/2466433 |url-status=live }}</ref><ref>{{Cite web |last=Boswell |first=Wendy |date=October 5, 2017 |title=Advanced Google Search Shortcuts |url=https://www.lifewire.com/advanced-google-search-3482174 |access-date=December 9, 2017 |website=[[Lifewire]] |publisher=[[Dotdash]] |archive-date=January 7, 2018 |archive-url=https://web.archive.org/web/20180107213428/https://www.lifewire.com/advanced-google-search-3482174 |url-status=live }}</ref>
* <code>OR</code> – Search for webpages containing one of two similar queries, such as ''marathon OR race''

Google also offers a '''Google Advanced Search''' page with a web interface to access the advanced features without needing to remember the special operators.<ref>{{cite web |url=https://www.google.com/advanced_search |title=Google Advanced Search |access-date=June 9, 2022 |website=Google |archive-date=June 8, 2022 |archive-url=https://web.archive.org/web/20220608214053/https://www.google.com/advanced_search |url-status=live }}</ref>


==== Query expansion ====
Google News provides searching, and the choice of sorting the results by date and time of publishing (not to be confused with date and time of the news happening) or grouping them (and also grouping without searching). In the English version, there is an option to tailor the grouping to a selected national audience.
Google applies [[query expansion]] to submitted search queries, using techniques to deliver results that it considers "smarter" than the query users actually submitted. This technique involves several steps, including:<ref>{{Cite web |last=Smarty |first=Ann |date=October 31, 2008 |title=What is Google Query Expansion?

* Word [[stemming]] – Certain words can be reduced so other, similar terms, are also found in results, so that ''"translator"'' can also search for ''"translation"''
* Acronyms – Searching for abbreviations can also return results about the name in its full length, so that ''"[[NATO]]"'' can show results for ''"North Atlantic Treaty Organization"''
* Misspellings – Google will often suggest correct spellings for misspelled words
* Synonyms – In most cases where a word is incorrectly used in a phrase or sentence, Google search will show results based on the correct synonym
* Translations – The search engine can, in some instances, suggest results for specific words in a different language
* Ignoring words – In some search queries containing extraneous or insignificant words, Google search will simply drop those specific words from the query

Users can request Google News Alerts on various topics by subscribing while using key words. An [[email]] is sent when a news article matching the request comes online.


In 2008, Google started to give users [[autocomplete]]d [[Search suggest drop-down list|search suggestions]] in a list below the search bar while typing, originally with the approximate result count previewed for each listed search suggestion.<ref>{{Cite web |last=Sullivan |first=Danny |date=August 25, 2008 |title=Google.com Finally Gets Google Suggest Feature |url=https://searchengineland.com/googlecom-finally-gets-google-suggest-feature-14626 |access-date=December 9, 2017 |website=[[Search Engine Land]] |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210071530/https://searchengineland.com/googlecom-finally-gets-google-suggest-feature-14626 |url-status=live }}</ref>

=== "I'm Feeling Lucky" ===
{{redirect|I'm Feeling Lucky|the 2011 book by Douglas Edwards|I'm Feeling Lucky (book){{!}}''I'm Feeling Lucky'' (book)}}
In April 2002, Google launched a new service called "Google Answers". Google Answers is an extension to the conventional search &mdash; rather than doing the search themselves, users pay someone else to do the search. Customers ask questions, offer a price for an answer, and researchers answer them. Researchers are screened through an application process that tests their research and communications abilities. Prices for questions range from $2 to $200; Google keeps 25% of the payment, sends the rest to the researchers, and charges an additional $0.50 listing fee. Once a question is answered, it remains available for anyone to browse for free. This service came out of beta in [[May 2003]] and presently receives more than one hundred question postings per day.


Google's homepage includes a button labeled "I'm Feeling Lucky". This feature originally allowed users to type in their search query, click the button and be taken directly to the first result, bypassing the search results page. Clicking it while leaving the search box empty opens Google's archive of [[Google Doodle|Doodles]].<ref>{{Cite web |date=April 12, 2016 |title=What Does The I'm Feeling Lucky Button On Google Search Do? |url=https://fossbytes.com/what-does-the-im-feeling-lucky-button-on-google-search-do/ |access-date=March 2, 2022 |website=Fossbytes |language=en-US |archive-date=February 5, 2023 |archive-url=https://web.archive.org/web/20230205064253/https://fossbytes.com/what-does-the-im-feeling-lucky-button-on-google-search-do/ |url-status=live }}</ref> With the 2010 announcement of [[#Instant search|Google Instant]], an automatic feature that immediately displays relevant results as users are typing in their query, the "I'm Feeling Lucky" button disappears, requiring that users opt-out of Instant results through search settings to keep using the "I'm Feeling Lucky" functionality.<ref>{{Cite web |last=Karch |first=Marziah |date=November 25, 2017 |title=How to Use Google's "I'm Feeling Lucky" Button |url=https://www.lifewire.com/im-feeling-lucky-button-1616813 |access-date=December 9, 2017 |website=[[Lifewire]] |publisher=[[Dotdash]] |archive-date=December 10, 2017 |archive-url=https://web.archive.org/web/20171210071809/https://www.lifewire.com/im-feeling-lucky-button-1616813 |url-status=live }}</ref> In 2012, "I'm Feeling Lucky" was changed to serve as an advertisement for Google services; users hover their computer mouse over the button, it spins and shows an emotion ("I'm Feeling Puzzled" or "I'm Feeling Trendy", for instance), and, when clicked, takes users to a Google service related to that emotion.<ref>{{Cite web |last=Paul |first=Ian |date=August 24, 2012 |title=Google Changes 'I'm Feeling Lucky' Button |url=https://www.pcworld.com/article/261363/google_changes_im_feeling_lucky_button.html |access-date=December 9, 2017 |website=[[PC World]] |publisher=[[International Data Group]] |archive-date=August 31, 2017 |archive-url=https://web.archive.org/web/20170831065633/http://www.pcworld.com/article/261363/google_changes_im_feeling_lucky_button.html |url-status=live }}</ref>
===Froogle===
In [[December 2003]], Google announced [[Froogle]], a spin-off that searches catalogues for particular products. This site had been active in beta for some months. It is now offered in [[Wireless Markup Language]] (WML) form and can be accessed from phones or other wireless devices that have support for WML.


[[Tom Chavez]] of "Rapt", a firm helping to determine a website's advertising worth, estimated in 2007 that Google lost $110 million in revenue per year due to use of the button, which bypasses the advertisements found on the search results page.<ref>{{Cite web |last=Newman |first=Brendan |author-link=Brendan Francis Newnam |date=November 19, 2007 |title=Are you feeling lucky?

===Gmail===
On [[April 1]], [[2004]], Google announced its own free [[webmail]] service, [[Gmail]], which would provide users with 1000 [[Megabyte|megabytes]] of storage for their mailboxes and would generate revenue by displaying advertisements from the AdWords service based on words in users' e-mail messages. Owing to [[April Fool's Day]], however, the company's press release was greeted with much skepticism in the technology world. Jonathan Rosenberg, Google's vice-president of products, re-assured [[BBC News]] by saying "We are very serious about Gmail."


=== Special interactive features ===
The service is set to allow up to 1000 MB of storage space. When Gmail was announced, this was vastly more than that of most other free [[webmail]] providers&mdash;for example, [[Microsoft]]'s [[Hotmail]] only offered 2 MB, and [[Yahoo!]]'s Mail service offered 4 MB. In response to Gmail, these limits have been upgraded, to 250 MB for Hotmail and 100 MB for Yahoo. Other webmail providers have followed suit, some of them now offering larger storage than Gmail.

However, the service is available to [[Blogger]] users and by invitation from current [[Gmail]] users. However, the invites system has led to gmail invites being exchanged for cash and goods through websites like [http://www.gmailswap.com/ Gmail swap], making Google change its policy on invites by disallowing cash exchanges.

During Google's developer conference, [[Google I/O]], in May 2013, the company announced that users on [[Google Chrome]] and [[ChromeOS]] would be able to have the browser initiate an audio-based search by saying "OK Google", with no button presses required.

==Operations==
There has been a great deal of criticism regarding Gmail's [http://gmail.google.com/gmail/help/privacy.html privacy policy]. Much of the controversy involved the clause "residual copies of email may remain on our systems for some time, even after you have deleted messages from your mailbox or after the termination of your account." Many believed that this meant that Google would intentionally archive copies of deleted mail forever. Google later stated that they will "make reasonable efforts to remove deleted information from our systems as quickly as is practical." Most of the criticism, however, was against Google's plans to add context-sensitive advertisements to e-mails by automatically scanning them.

===Google Web API===
The Google Web [[API]] (or Google Web Services) is Google's public interface for registered developers. Using [[Simple Object Access Protocol]] (SOAP), a programmer can write services for search and data-mining that rely on Google's results. Also, websurfers can view cached pages and make suggestions for better spelling.


There are also products available from Google that are not directly search-related. [[Gmail]], for example, is a [[webmail]] application, but still includes search features; [[Google Browser Sync]] does not offer any search facilities, although it aims to organize your browsing time.
By default a developer has a limit of 1,000 requests per day. This program is still in Beta phase. Google is one of the few search engines to make its results available via a public API; [[Technorati]] is another good example. Some popular implementations of the Google Web API include the alerting service Google Alert, as well as the Google Dance Tool, which monitors when Google is spidering the Internet.

Though not mentioned on the Google homepage, [[Orkut]] is a service hosted, created and maintained by Google engineers. Orkut is a relationship database, where users can list their personal and professional information, create relationships amongst friends and join communities of mutual interest.


=== Google Doodles ===
There is some speculation saying that Orkut and Gmail are part of a Google effort to gather information about their users, with the intention of offering a better [[personalized search]] service in future. Google already has a personalized search in Google Labs.
{{Main|Google Doodle}}


On certain occasions, the [[Google logo|logo]] on Google's webpage will change to a special version, known as a "Google Doodle". This is a picture, drawing, animation, or interactive game that includes the logo. It is usually done for a special event or day although not all of them are well known.<ref>[https://www.google.com/doodles/about About Google Doodles] {{Webarchive|url=https://web.archive.org/web/20190320083151/http://www.google.com/doodles/about |date=March 20, 2019 }}.

===Blogger===
In [[2003]] the search engine Google acquired the [[Pyra Labs]] and the [[Blogger]] service. Formerly premium features that needed to be paid for were made available for free by Google.


== Criticism ==
The tool Blogger is a service to make [[weblog]] publishing easier. The user does not have to write any code or to worry about installing server software or scripts. But nevertheless the user can influence the design of his blog freely.


===Other tools===
=== Privacy ===
{{Main|Privacy concerns regarding Google}}
*Google offers a [[pay-per-click]] ad service called [[AdWords]] that allows advertisers to display their ads alongside Google search results and on web sites that participate in the [[AdSense]] program.
*AdSense allows web site owners to display Google ads on their site that generate income every time a visitor clicks. The service uses Google's relevance technology to match the ads to the content of the pages they are displayed on.
*Google provides experimental [[machine translation]] services between several languages.
*Google includes a [[calculator]] and [[units converter]], see [[Google#Google_calculator|below]].
*In [[May 2002]], Google launched the beta version of Google Glossary as a part of Google Labs. It is a search tool that, for a given word, retrieves the definitions it has been given on various web pages. After the beta test, Google now merged Google Glossary with Google search engine; the current version is called Google Definitions.
*In [[September 2003]], Google launched the beta version of Search by Location, which acts like a normal Google search, but lets users geographically restrict the search (within the U.S.) by state, city or [[zip code]]. It will also provide users with maps to the listed sites, and an estimate on the distance, and direction. This service has since been renamed Google Local.
*In [[March 2004]], Google Labs launched two more beta features. One, a version of Personalized Web Search, is a search tool that fetches search results based upon the profile/interests users specify. The other is Google Web Alerts, a tool that will send an alert by email when there is new information on the web matching the search users specify.


Google has been criticized for placing long-term [[HTTP cookie|cookies]] on users' machines to store preferences, a tactic which also enables them to track a user's search terms and retain the data for more than a year.<ref name="ac">{{Cite magazine |last=Caddy, Becca |date=March 20, 2017 |title=Google tracks everything you do: here's how to delete it |magazine=Wired |url=https://www.wired.co.uk/article/google-history-search-tracking-data-how-to-delete |access-date=March 20, 2017 |url-status=live |archive-url= https://web.archive.org/web/20170324030045/https://www.wired.co.uk/article/google-history-search-tracking-data-how-to-delete |archive-date= Mar 24, 2017 }}</ref>
==Google's software tools==
===Google Toolbar===
This addition to [[Microsoft Internet Explorer]] 5 or later adds Google's searching capabilities in a toolbar in the browser. The latest version includes [[pop-up ads blocking]], automatic filling of forms, and the ability to show the Google PageRank value for the current page being viewed. It has been criticized for being a security risk because it updates itself without user intervention.


Since 2012, Google Inc. has globally introduced encrypted connections for most of its clients, to bypass governative blockings of the commercial and IT services.<ref>{{Cite news |date=March 12, 2014 |title=Google is encrypting search globally. That's bad for the NSA and China's censors |newspaper=[[The Washington Post]] |url=https://www.washingtonpost.com/news/the-switch/wp/2014/03/12/google-is-encrypting-search-worldwide-thats-bad-for-the-nsa-and-china/?noredirect=on |url-access=subscription |author1=Craig Timberg |author2=JIa Lynn Yang |access-date=July 7, 2018 |archive-date=December 3, 2018 |archive-url=https://web.archive.org/web/20181203054419/https://www.washingtonpost.com/news/the-switch/wp/2014/03/12/google-is-encrypting-search-worldwide-thats-bad-for-the-nsa-and-china/?noredirect=on |url-status=live }}</ref>
A separately downloadable add-on for the toolbar allows participation in [[Google Compute]], a [[distributed computing]] project to help scientific research.


=== Complaints about indexing ===
Other browsers, such as [[Mozilla Firefox]] and [[Safari (browser)|Safari]], have built-in search tools that offer the same functionality. Mozilla Firefox also has its own version of the Google Toolbar, the Googlebar, which is developed independently of and is not supported by Google or the Mozilla Firefox developers. It expands upon the official google toolbar to the point that the only feature not replicated is the Google PageRank functionality. Google has also been built into [[Safari_%28browser%29|Safari]] for [[Apple Computer]]'s new [[OS X]] [[operating system]].
In 2003, ''[[The New York Times]]'' complained about Google's [[Search engine indexing|indexing]], claiming that Google's [[Web cache|caching]] of content on its site infringed its copyright for the content.<ref>{{Cite web |last=Olsen |first=Stefanie |date=July 9, 2003 |title=Google cache raises copyright concerns |url=http://news.cnet.com/2100-1038_3-1024234.html |access-date=June 13, 2010 |website=[[CNET]] |publisher=[[CBS Interactive]] |archive-date=May 10, 2011 |archive-url=https://web.archive.org/web/20110510075319/http://news.cnet.com/2100-1038_3-1024234.html |url-status=dead }}</ref> In both ''[[Field v.

===Google Deskbar===
=== Child sexual abuse ===
A 2019 ''New York Times'' article on Google Search showed that images of [[child sexual abuse]] had been found on Google and that the company had been reluctant at times to remove them.<ref>{{Cite news |last1=Keller |first1=Michael H. |last2=Dance |first2=Gabriel J.

In December 2003, Google launched the beta version of the Google Deskbar, a search tool which runs from the [[Microsoft Windows]] [[taskbar]], without a [[web browser|browser]] having to be open. It can return film reviews, stock quotes, [[dictionary]] and [[thesaurus]] definitions, plus any pre-configured search of a third-party site (e.g. [[eBay]] or [[Amazon.com|Amazon]]).


=== January 2009 malware bug ===
===Puffin===
[[File:Google Search error of January 31, 2009.png|thumb|right|A screenshot of the error of January 31, 2009]]
Google is [http://www.nytimes.com/2004/05/19/technology/19google.html?ex=1091505600&en=2c6b32d3e5c0a6d4&ei=5070 reportedly] working on a downloadable tool, code-named Puffin, for searching local files. Puffin is likely being developed in response to file and Web search capabilities that will be offered in the next major release of Microsoft Windows, currently (2004) codenamed [[Windows Longhorn|Longhorn]]--features that directly compete with Google's core Internet search business.


Google flags search results with the message "This site may harm your computer" if the site is known to install malicious software in the background or otherwise surreptitiously. For approximately 40 minutes on January 31, 2009, all search results were mistakenly classified as [[malware]] and could therefore not be clicked; instead a warning message was displayed and the user was required to enter the requested URL manually. The bug was caused by human error.<ref>{{Cite news |last=Krebs |first=Brian |date=January 31, 2009 |title=Google: This Internet May Harm Your Computer |newspaper=The Washington Post |url=http://voices.washingtonpost.com/securityfix/2009/01/google_this_internet_will_harm.html?hpid=news-col-blog |access-date=January 31, 2009 |archive-date=November 30, 2011 |archive-url=https://web.archive.org/web/20111130155700/http://voices.washingtonpost.com/securityfix/2009/01/google_this_internet_will_harm.html?hpid=news-col-blog |url-status=dead }}</ref><ref name="googleblog">{{Cite web |last=Mayer |first=Marissa |date=January 31, 2009 |title=This site may harm your computer on every search result?!?! |url=http://googleblog.blogspot.com/2009/01/this-site-may-harm-your-computer-on.html |access-date=January 31, 2009 |website=Official Google Blog |archive-date=February 2, 2009 |archive-url=https://web.archive.org/web/20090202063204/http://googleblog.blogspot.com/2009/01/this-site-may-harm-your-computer-on.html |url-status=live }}</ref><ref name="stopbadware">{{Cite web |last=Weinstein |first=Maxim |date=January 31, 2009 |title=Google glitch causes confusion |url=http://blog.stopbadware.org/2009/01/31/google-glitch-causes-confusion |url-status=dead |archive-url=https://web.archive.org/web/20100708013913/http://blog.stopbadware.org/2009/01/31/google-glitch-causes-confusion |archive-date=July 8, 2010 |access-date=May 10, 2010 |publisher=StopBadware }}</ref><ref>{{Cite web |last=Cooper |first=Russ |date=January 31, 2009 |title=Serious problems with Google search |url=http://securityblog.verizonbusiness.com/2009/01/31/serious-problems-with-google-search/ |url-status=dead |archive-url=https://web.archive.org/web/20110717193934/http://securityblog.verizonbusiness.com/2009/01/31/serious-problems-with-google-search/ |archive-date=July 17, 2011 |access-date=May 10, 2010 |publisher=Verizon Business Security Blog}}</ref>&nbsp;The [[URL]] of "/" (which expands to all URLs) was mistakenly added to the malware patterns file.<ref name="googleblog" /><ref name="stopbadware" />
==Criticism of Google==


=== Possible misuse of search results ===
While Google's apparent effectiveness has led droves of people to use it as their primary search tool, Google has managed to become the target of critics. Online journalists disliked that Google News equated press releases with news articles. In [[February 2003]], Google banned the ads of [[Oceana (non-profit group)|Oceana]], a two and a half year old non-profit group, which was protesting over a major cruise line's sewage treatment methods. [[Chris Hoofnagle]], associate director of the [[Electronic Privacy Information Center]] in [[Washington, DC]] warned that "As courts become more frequent integrators of electronic records, there is a greater risk of Google ... becoming a serious privacy threat."
In 2007, a group of researchers observed a tendency for users to rely exclusively on Google Search for finding information, writing that "With the Google interface the user gets the impression that the search results imply a kind of totality.&nbsp;... In fact, one only sees a small part of what one could see if one also integrates other research tools."<ref>{{Cite web |last1=Maurer |first1=H. |last2=Balke |first2=Tilo |last3=Kappe |first3=Frank |last4=Kulathuramaiyer |first4=Narayanan |last5=Weber |first5=Stefan |last6=Zaka |first6=Bilal |date=September 30, 2007 |title=Report on dangers and opportunities posed by large search engines, particularly Google |url=http://www.iicm.tugraz.at/iicm_papers/dangers_google.pdf |archive-url=https://web.archive.org/web/20091229105054/http://www.iicm.tugraz.at/iicm_papers/dangers_google.pdf |archive-date=December 29, 2009 |access-date=June 13, 2017 |website=[[Graz University of Technology]]}}</ref>


In 2011, Google Search query results have been shown by Internet activist [[Eli Pariser]] to be tailored to users, effectively isolating users in what he defined as a [[filter bubble]]. Pariser holds algorithms used in search engines such as Google Search responsible for catering "a personal ecosystem of information".<ref>{{Cite news |last=Parramore |first=Lynn |date=October 10, 2010 |title=The Filter Bubble |work=The Atlantic |url=https://www.theatlantic.com/daily-dish/archive/2010/10/the-filter-bubble/181427/ |access-date=April 20, 2011 |quote=Since Dec. 4, 2009, Google has been personalized for everyone.

===Claims of partiality===


=== FTC fines ===
In April 2004, Google received complaints about the way that a search for "[[Jew]]" on its site listed the anti-Jewish website [[Jew Watch]] at or towards the top of the list. Google insisted this was a result of their content-neutral algorithm responding to the high PageRank of the Jew Watch website[http://www.google.com/explanation.html]. A [[Google bomb]] was employed to place [[Wikipedia]]'s entry, [[w:Jew|Jew]], at the top. Jew Watch was also highly ranked in other search engines, such as Yahoo! and MSN, but those companies apparently received little or no criticism.
In 2012, the US [[Federal Trade Commission]] fined Google [[US$]]22.5 million for violating their agreement not to violate the privacy of users of Apple's [[Safari (web browser)|Safari web browser]].<ref>[http://www.aljazeera.com//news/americas/2012/08/201289172541616218.html "Google fined over Safari privacy violation"] {{Webarchive|url=https://web.archive.org/web/20120811210329/http://www.aljazeera.com/news/americas/2012/08/201289172541616218.html |date=August 11, 2012 }}. ''Al Jazeera'', August 10, 2012.</ref> The FTC was also continuing to investigate if Google's favoring of their own services in their search results violated antitrust regulations.<ref>Bailey, Brandon.

''Mercury News'', November 9, 2012.</ref>


===Payments to Apple===
Jew Watch's main page was dropped from Google's results at the end of April because Jew Watch's web hosting service [[EV1]] cancelled its account, and the site was inaccessible for several days. Since Google's webcrawler could not reach the site after repeated attempts, the main page was dropped from Google's index. [http://news.com.com/2100-1038_3-5200203.html] The site later found another hosting service and was re-indexed by Google during the first week of May. Google explains that "The only sites we omit are those we are legally compelled to remove," in its disclaimer "Offensive Search Results" of April 23, 2004.
In a November 2023 disclosure, during the ongoing antitrust trial against Google, an economics professor at the [[University of Chicago]] revealed that Google pays Apple 36% of all search advertising revenue generated when users access Google through the Safari browser. This revelation reportedly caused Google's lead attorney to cringe visibly. The revenue generated from Safari users has been kept confidential, but the 36% figure suggests that it is likely in the tens of billions of dollars.


Both Apple and Google have argued that disclosing the specific terms of their search default agreement would harm their competitive positions. However, the court ruled that the information was relevant to the antitrust case and ordered its disclosure. This revelation has raised concerns about the dominance of Google in the search engine market and the potential anticompetitive effects of its agreements with Apple.<ref>{{cite news |last=Nylen |first=Leah |url=https://www.bloomberg.com/news/articles/2023-11-13/apple-gets-36-of-google-revenue-from-search-deal-witness-says |title=Apple Gets 36% of Google Revenue in Search Deal, Expert Says |work=Bloomberg News |date=2023-11-13 |accessdate=2023-11-14 }}</ref>
===Claims of censorship===


=== Big data and human bias ===
Sites advocating race as a virtue or historical revisionism have been banned for years in the French and German Googles, as such speech is illegal in those countries. Other potentially controversial sites such as hardcore [[pornography|pornographic]] sites have remained unaffected, however, and [[web-filtering program]]s have no effect on searches run from Google's Image section.
Google [[Web search engine|search engine]] robots are programmed to use [[algorithm]]s that understand and predict human [[behavior]]. The book, ''Race After Technology: Abolitionist Tools for the New Jim Code''<ref name=":1">{{Cite book |last=Benjamin |first=Ruha |title=Race After Technology: Abolitionist Tools for the New Jim Code |publisher=Polity Press |year=2019 |isbn=9781509526437 |location=65 Bridge Street Cambridge CB2 1UR, UK |pages=94–95}}</ref> by [[Ruha Benjamin]] talks about human [[bias]] as a behavior that the Google search engine can recognize. In 2016, some users google searched "three Black teenagers" and images of criminal [[Mug shot|mugshots]] of young African American teenagers came up. Then, the users searched "three White teenagers" and were presented with photos of smiling, happy teenagers. They also searched for "three Asian teenagers", and very revealing photos of Asian girls and women appeared. Benjamin concluded that these results reflect human [[prejudice]] and views on different [[ethnic group]]s. A group of analysts explained the concept of a [[Racism|racist]] computer program: "The idea here is that computers, unlike people, can't be racist but we're increasingly learning that they do in fact take after their makers&nbsp;... Some experts believe that this problem might stem from the hidden biases in the massive piles of [[data]] that the algorithms process as they learn to recognize patterns&nbsp;... reproducing our worst values".<ref name=":1" />


== Trademark ==
===Claims of privacy invasion===

As people talk about "googling" rather than searching, the company has taken some steps to defend its trademark, in an effort to prevent it from becoming a [[generic trademark]].<ref>{{Cite news |last=Duffy |first=Jonathan |date=June 20, 2003 |title=Google calls in the 'language police' |work=BBC News |url=http://news.bbc.co.uk/2/hi/uk_news/3006486.stm |access-date=April 10, 2019 |archive-date=June 29, 2012 |archive-url=https://archive.today/20120629/http://news.bbc.co.uk/2/hi/uk_news/3006486.stm |url-status=live }}</ref><ref>{{Cite web |last1=Ash |first1=Karen Artz |last2=Danow |first2=Bret J. |title="Google It": The Search Engine's Trademark May Be a Verb, But It's Not Generic |url=https://www.natlawreview.com/article/google-it-search-engine-s-trademark-may-be-verb-it-s-not-generic |access-date=April 10, 2019 |website=The National Law Review |archive-date=April 10, 2019 |archive-url=https://web.archive.org/web/20190410060515/https://www.natlawreview.com/article/google-it-search-engine-s-trademark-may-be-verb-it-s-not-generic |url-status=live }}</ref> This has led to lawsuits, threats of lawsuits, and the use of euphemisms, such as calling Google Search a '''famous web search engine'''.<ref>{{Cite web |date=June 5, 2013 |title=Feedback: Weight in dollars squared |url=https://www.newscientist.com/article/mg21829202-500-feedback-weight-in-dollars-squared/ |access-date=November 8, 2020 |website=New Scientist |language=en-US |archive-date=April 26, 2021 |archive-url=https://web.archive.org/web/20210426200552/https://www.newscientist.com/article/mg21829202-500-feedback-weight-in-dollars-squared/ |url-status=live }}</ref>


== Discontinued features ==
It has been claimed that Google infringes the privacy of visitors by uniquely identifying them using [[cookies]]. It is claimed the cookies possess excessively distant expiry dates and that users' searches are recorded without permission for advertising purposes. In their defense Google claim cookies are necessary to maintain user preferences between sessions and the website otherwise functions normally if the user turns down the cookies.
=== Translate foreign pages ===
Until May 2013, Google Search had offered a feature to [[Cross-language information retrieval|translate search queries into other languages]]. A Google spokesperson told ''[[Search Engine Land]]'' that "Removing features is always tough, but we do think very hard about each decision and its implications for our users. Unfortunately, this feature never saw much pick up".<ref>{{Cite web |last=Schwartz |first=Barry |date=May 20, 2013 |title=Google Drops "Translated Foreign Pages" Search Option Due To Lack Of Use |url=https://searchengineland.com/google-drops-translated-foreign-pages-search-option-due-to-lack-of-use-160157 |access-date=December 15, 2017 |website=[[Search Engine Land]] |archive-date=October 17, 2017 |archive-url=https://web.archive.org/web/20171017042951/https://searchengineland.com/google-drops-translated-foreign-pages-search-option-due-to-lack-of-use-160157 |url-status=live }}</ref>

Some users believe the processing of email message content by Google's GMail service goes beyond proper use. The point is often made that people without GMail accounts, who have not agreed to the GMail terms of service, but send email to GMail users have their correspondence analyzed without permission. Google claims that mail sent to or from GMail is never read by a human being, and is only used to improve relevance of advertisements.
Instant search was announced in September 2010 as a feature that [[Incremental search|displayed suggested results while the user typed in their search query]], initially only in select countries or to registered users.<ref>{{Cite web |date=September 8, 2010 |title=Google Instant Search: The Complete User's Guide |url=https://searchengineland.com/google-instant-complete-users-guide-50136 |access-date=October 5, 2021 |website=Search Engine Land |language=en |quote=Google Instant only works for searchers in the US or who are logged in to a Google account in selected countries outside the US |archive-date=October 20, 2021 |archive-url=https://web.archive.org/web/20211020125043/https://searchengineland.com/google-instant-complete-users-guide-50136 |url-status=live }}</ref> The primary advantage of the new system was its ability to save time, with [[Marissa Mayer]], then-vice president of search products and user experience, proclaiming that the feature would save 2–5 seconds per search, elaborating that "That may not seem like a lot at first, but it adds up. With Google Instant, we estimate that we'll save our users 11 hours with each passing second!"<ref>{{Cite web |last=Mayer |first=Marissa |author-link=Marissa Mayer |date=September 8, 2010 |title=Search: now faster than the speed of type |url=https://googleblog.blogspot.no/2010/09/search-now-faster-than-speed-of-type.html |access-date=December 15, 2017 |website=Official Google Blog |archive-date=December 15, 2017 |archive-url=https://web.archive.org/web/20171215221553/https://googleblog.blogspot.no/2010/09/search-now-faster-than-speed-of-type.html |url-status=live }}</ref> Matt Van Wagner of ''[[Search Engine Land]]'' wrote that "Personally, I kind of like Google Instant and I think it represents a natural evolution in the way search works", and also praised Google's efforts in [[public relations]], writing that "With just a press conference and a few well-placed interviews, Google has parlayed this relatively minor speed improvement into an attention-grabbing front-page news story".<ref>{{Cite web |last=Wagner |first=Matt Van |date=September 20, 2010 |title=How Google Saved $100 Million By Launching Google Instant |url=https://searchengineland.com/how-google-saved-100-million-by-launching-google-instant-51270 |access-date=December 15, 2017 |website=[[Search Engine Land]] |archive-date=October 19, 2017 |archive-url=https://web.archive.org/web/20171019111500/https://searchengineland.com/how-google-saved-100-million-by-launching-google-instant-51270 |url-status=live }}</ref> The upgrade also became notable for the company switching Google Search's underlying technology from [[HTML]] to [[Ajax (programming)|AJAX]].<ref>{{Cite web |last=Gomes |first=Ben |date=September 9, 2010 |title=Google Instant, behind the scenes |url=https://googleblog.blogspot.no/2010/09/google-instant-behind-scenes.html |access-date=December 15, 2017 |website=Official Google Blog |archive-date=December 15, 2017 |archive-url=https://web.archive.org/web/20171215221508/https://googleblog.blogspot.no/2010/09/google-instant-behind-scenes.html |url-status=live }}</ref>

===Criticisms of PageRank system===


The publication ''[[2600: The Hacker Quarterly]]'' compiled a list of words that Google Instant did not show suggested results for, with a Google spokesperson giving the following statement to ''[[Mashable]]'':<ref>{{Cite web |last=Axon |first=Samuel |date=September 28, 2010 |title=Which Words Does Google Instant Blacklist? |url=http://mashable.com/2010/09/28/google-instant-blacklist/ |access-date=December 15, 2017 |website=[[Mashable]] |publisher=[[Ziff Davis]] |archive-date=December 15, 2017 |archive-url=https://web.archive.org/web/20171215221427/http://mashable.com/2010/09/28/google-instant-blacklist/ |url-status=live }}</ref>
Google's central PageRank system has been criticized, some calling it 'undemocratic'. Common arguments by Google's detractors are that the system is unfairly biased towards large sites, and that the criteria for a page's importance are not subject to [[peer review]].


{{Blockquote|There are several reasons you may not be seeing search queries for a particular topic. Among other things, we apply a narrow set of removal policies for pornography, violence, and hate speech. It's important to note that removing queries from Autocomplete is a hard problem, and not as simple as blacklisting particular terms and phrases.
==Books==
*''[[Google Hacks]]'' from [[O'Reilly & Associates]] is a book containing tips about using Google effectively.


In search, we get more than one billion searches each day. Because of this, we take an algorithmic approach to removals, and just like our search algorithms, these are imperfect. We will continue to work to improve our approach to removals in Autocomplete, and are listening carefully to feedback from our users.

Our algorithms look not only at specific words, but compound queries based on those words, and across all languages. So, for example, if there's a bad word in Russian, we may remove a compound word including the transliteration of the Russian word into English. We also look at the search results themselves for given queries. So, for example, if the results for a particular query seem pornographic, our algorithms may remove that query from Autocomplete, even if the query itself wouldn't otherwise violate our policies. This system is neither perfect nor instantaneous, and we will continue to work to make it better.}}

''[[PC Magazine]]'' discussed the inconsistency in how some forms of the same topic are allowed; for instance, "lesbian" was blocked, while "gay" was not, and "cocaine" was blocked, while "crack" and "heroin" were not. The report further stated that seemingly normal words were also blocked due to pornographic innuendos, most notably "scat", likely due to having two completely separate contextual meanings, one for music and one for a sexual practice.<ref>{{Cite magazine |last=Horn |first=Leslie |date=September 29, 2010 |title=Google Instant Blacklist: Which Words Are Blocked? |url=https://www.pcmag.com/article2/0,2817,2369908,00.asp |access-date=December 15, 2017 |magazine=[[PC Magazine]] |publisher=[[Ziff Davis]]}}</ref>

All of these Google sites produce nearly the same search results, though they may be in a different order. Illegal sites are censored in localized versions of Google, such as domain "whitepower.com" in Google Germany. National Google sites allow users to search on a global basis or just for sites from that country. Some countries may have different default language settings.

Google Search (also known simply as Google or Google.com) is a search engine operated by Google. It allows users to search for information on the Internet by entering keywords or phrases. Google Search uses algorithms to analyze and rank websites based on their relevance to the search query. It is the most popular search engine worldwide.

As of 2020, Google Search has a 92% share of the global search engine market.[3] By 2012, it handled more than 3.5 billion searches per day.[4]

Google Search is the most-visited website in the world. Approximately 26.75% of Google's monthly global traffic comes from the United States, 4.44% from India, 4.4% from Brazil, 3.92% from the United Kingdom and 3.84% from Japan according to data provided by Similarweb.[5]

The order of search results returned by Google is based, in part, on a priority rank system called "PageRank". Google Search also provides many different options for customized searches, using symbols to include, exclude, specify or require certain search behavior, and offers specialized interactive experiences, such as flight status and package tracking, weather forecasts, currency, unit, and time conversions, word definitions, and more.

The main purpose of Google Search is to search for text in publicly accessible documents offered by web servers, as opposed to other data, such as images or data contained in databases. It was originally developed in 1996 by Larry Page, Sergey Brin, and Scott Hassan.[6][7][8] In 2011, Google introduced "Google Voice Search" to search for spoken, rather than typed, words.[9] In 2012, Google introduced a semantic search feature named Knowledge Graph.

Analysis of the frequency of search terms may indicate economic, social and health trends.[10] Data about the frequency of use of search terms on Google can be openly inquired via Google Trends and have been shown to correlate with flu outbreaks and unemployment levels, and provide the information faster than traditional reporting methods and surveys. As of mid-2016, Google's search engine has begun to rely on deep neural networks.[11]

Search indexing

Google indexes hundreds of terabytes of information from web pages.[12] For websites that are currently down or otherwise not available, Google provides links to cached versions of the site, formed by the search engine's latest indexing of that page.[13] Additionally, Google indexes some file types, being able to show users PDFs, Word documents, Excel spreadsheets, PowerPoint presentations, certain Flash multimedia content, and plain text files.[14] Users can also activate "SafeSearch", a filtering technology aimed at preventing explicit and pornographic content from appearing in search results.[15]

Despite Google search's immense index, sources generally assume that Google is only indexing less than 5% of the total Internet, with the rest belonging to the deep web, inaccessible through its search tools.[12][16][17]

In 2012, Google changed its search indexing tools to demote sites that had been accused of piracy.[18] In October 2016, Gary Illyes, a webmaster trends analyst with Google, announced that the search engine would be making a separate, primary web index dedicated for mobile devices, with a secondary, less up-to-date index for desktop use. The change was a response to the continued growth in mobile usage, and a push for web developers to adopt a mobile-friendly version of their websites.[19][20] In December 2017, Google began rolling out the change, having already done so for multiple websites.[21]

"Caffeine" search architecture upgrade

In August 2009, Google invited web developers to test a new search architecture, codenamed "Caffeine", and give their feedback. The new architecture provided no visual differences in the user interface, but added significant speed improvements and a new "under-the-hood" indexing infrastructure. The move was interpreted in some quarters as a response to Microsoft's recent release of an upgraded version of its own search service, renamed Bing, as well as the launch of Wolfram Alpha, a new search engine based on "computational knowledge".[22][23] Google announced completion of "Caffeine" on June 8, 2010, claiming 50% fresher results due to continuous updating of its index.[24]

With "Caffeine", Google moved its back-end indexing system away from MapReduce and onto Bigtable, the company's distributed database platform.[25][26]

"Medic" search algorithm update

In August 2018, Danny Sullivan from Google announced a broad core algorithm update. As per current analysis done by the industry leaders Search Engine Watch and Search Engine Land, the update was to drop down the medical and health-related websites that were not user friendly and were not providing good user experience. This is why the industry experts named it "Medic".[27]

Google reserves very high standards for YMYL (Your Money or Your Life) pages. This is because misinformation can affect users financially, physically, or emotionally. Therefore, the update targeted particularly those YMYL pages that have low-quality content and misinformation. This resulted in the algorithm targeting health and medical-related websites more than others. However, many other websites from other industries were also negatively affected.[28]

Search results

Ranking of results

In 2013 the European Commission found that Google Search favored Google's own products, instead of the best result for consumers' needs.[29] In February 2015 Google announced a major change to its mobile search algorithm which would favor mobile friendly over other websites. Nearly 60% of Google searches come from mobile phones. Google says it wants users to have access to premium quality websites. Those websites which lack a mobile-friendly interface would be ranked lower and it is expected that this update will cause a shake-up of ranks. Businesses who fail to update their websites accordingly could see a dip in their regular websites traffic.[30]

PageRank

Google's rise was largely due to a patented algorithm called PageRank which helps rank web pages that match a given search string.[31] When Google was a Stanford research project, it was nicknamed BackRub because the technology checks backlinks to determine a site's importance. Other keyword-based methods to rank search results, used by many search engines that were once more popular than Google, would check how often the search terms occurred in a page, or how strongly associated the search terms were within each resulting page. The PageRank algorithm instead analyzes human-generated links assuming that web pages linked from many important pages are also important. The algorithm computes a recursive score for pages, based on the weighted sum of other pages linking to them. PageRank is thought to correlate well with human concepts of importance. In addition to PageRank, Google, over the years, has added many other secret criteria for determining the ranking of resulting pages. This is reported to comprise over 250 different indicators,[32][33] the specifics of which are kept secret to avoid difficulties created by scammers and help Google maintain an edge over its competitors globally.

PageRank was influenced by a similar page-ranking and site-scoring algorithm earlier used for RankDex, developed by Robin Li in 1996. Larry Page's patent for PageRank filed in 1998 includes a citation to Li's earlier patent. Li later went on to create the Chinese search engine Baidu in 2000.[34][35]

In a potential hint of Google's future direction of their Search algorithm, Google's then chief executive Eric Schmidt, said in a 2007 interview with the Financial Times: "The goal is to enable Google users to be able to ask the question such as 'What shall I do tomorrow?' and 'What job shall I take?'".[36] Schmidt reaffirmed this during a 2010 interview with The Wall Street Journal: "I actually think most people don't want Google to answer their questions, they want Google to tell them what they should be doing next."[37]

Google optimization

Because Google is the most popular search engine, many webmasters attempt to influence their website's Google rankings. An industry of consultants has arisen to help websites increase their rankings on Google and other search engines. This field, called search engine optimization, attempts to discern patterns in search engine listings, and then develop a methodology for improving rankings to draw more searchers to their clients' sites. Search engine optimization encompasses both "on page" factors (like body copy, title elements, H1 heading elements and image alt attribute values) and Off Page Optimization factors (like anchor text and PageRank). The general idea is to affect Google's relevance algorithm by incorporating the keywords being targeted in various places "on page", in particular the title element and the body copy (note: the higher up in the page, presumably the better its keyword prominence and thus the ranking). Too many occurrences of the keyword, however, cause the page to look suspect to Google's spam checking algorithms. Google has published guidelines for website owners who would like to raise their rankings when using legitimate optimization consultants.[38] It has been hypothesized, and, allegedly, is the opinion of the owner of one business about which there have been numerous complaints, that negative publicity, for example, numerous consumer complaints, may serve as well to elevate page rank on Google Search as favorable comments.[39] The particular problem addressed in The New York Times article, which involved DecorMyEyes, was addressed shortly thereafter by an undisclosed fix in the Google algorithm. According to Google, it was not the frequently published consumer complaints about DecorMyEyes which resulted in the high ranking but mentions on news websites of events which affected the firm such as legal actions against it. Google Search Console helps to check for websites that use duplicate or copyright content.[40]

"Hummingbird" search algorithm upgrade

In 2013, Google significantly upgraded its search algorithm with "Hummingbird". Its name was derived from the speed and accuracy of the hummingbird.[41] The change was announced on September 26, 2013, having already been in use for a month.[42] "Hummingbird" places greater emphasis on natural language queries, considering context and meaning over individual keywords.[41] It also looks deeper at content on individual pages of a website, with improved ability to lead users directly to the most appropriate page rather than just a website's homepage.[43] The upgrade marked the most significant change to Google search in years, with more "human" search interactions[44] and a much heavier focus on conversation and meaning.[41] Thus, web developers and writers were encouraged to optimize their sites with natural writing rather than forced keywords, and make effective use of technical web development for on-site navigation.[45]

Search results quality

In the 2020s, observers reported on a perceived declining quality of search results found in Google Search.[46]

In 2023, drawing on internal Google documents disclosed as part of the United States v. Google LLC (2020) antitrust case, technology reporters claimed that Google Search was "bloated and overmonetized"[47] and that the "semantic matching" of search queries put advertising profits before quality.[48] Wired withdrew Megan Gray's piece after Google complained about alleged inaccuracies, while the author reiterated that «As stated in court, "A goal of Project Mercury was to increase commercial queries"».[49]

In March 2024, Google announced a significant update to its core search algorithm and spam targeting, which is expected to wipe out 40 percent of all spam results.[50] On March 20th, it was confirmed that the roll out of the spam update was complete.[51]

Interface

Page layout

At the top of the search page, the approximate result count and the response time two digits behind decimal is noted. Of search results, page titles and URLs, dates, and a preview text snippet for each result appears. Along with web search results, sections with images, news, and videos may appear.[52] The length of the previewed text snipped was experimented with in 2015 and 2017.[53][54]

Universal search

"Universal search" was launched by Google on May 16, 2007, as an idea that merged the results from different kinds of search types into one. Prior to Universal search, a standard Google search would consist of links only to websites. Universal search, however, incorporates a wide variety of sources, including websites, news, pictures, maps, blogs, videos, and more, all shown on the same search results page.[55][56] Marissa Mayer, then-vice president of search products and user experience, described the goal of Universal search as "we're attempting to break down the walls that traditionally separated our various search properties and integrate the vast amounts of information available into one simple set of search results.[57]

In June 2017, Google expanded its search results to cover available job listings. The data is aggregated from various major job boards and collected by analyzing company homepages. Initially only available in English, the feature aims to simplify finding jobs suitable for each user.[58][59]

Rich snippets

In May 2009, Google announced that they would be parsing website microformats to populate search result pages with "Rich snippets". Such snippets include additional details about results, such as displaying reviews for restaurants and social media accounts for individuals.[60]

In May 2016, Google expanded on the "Rich snippets" format to offer "Rich cards", which, similarly to snippets, display more information about results, but shows them at the top of the mobile website in a swipeable carousel-like format.[61] Originally limited to movie and recipe websites in the United States only, the feature expanded to all countries globally in 2017.[62]

Knowledge Graph

The Knowledge Graph is a knowledge base used by Google to enhance its search engine's results with information gathered from a variety of sources.[63] This information is presented to users in a box to the right of search results.[64] Knowledge Graph boxes were added to Google's search engine in May 2012,[63] starting in the United States, with international expansion by the end of the year.[65] The information covered by the Knowledge Graph grew significantly after launch, tripling its original size within seven months,[66] and being able to answer "roughly one-third" of the 100 billion monthly searches Google processed in May 2016.[67] The information is often used as a spoken answer in Google Assistant[68] and Google Home searches.[69] The Knowledge Graph has been criticized for providing answers without source attribution.[67]

Personal tab

In May 2017, Google enabled a new "Personal" tab in Google Search, letting users search for content in their Google accounts' various services, including email messages from Gmail and photos from Google Photos.[70][71]

Google Discover

Google Discover, previously known as Google Feed, is a personalized stream of articles, videos, and other news-related content. The feed contains a "mix of cards" which show topics of interest based on users' interactions with Google, or topics they choose to follow directly.[72] Cards include, "links to news stories, YouTube videos, sports scores, recipes, and other content based on what [Google] determined you're most likely to be interested in at that particular moment."[72] Users can also tell Google they're not interested in certain topics to avoid seeing future updates.

Google Discover launched in December 2016[73] and received a major update in July 2017.[74] Another major update was released in September 2018, which renamed the app from Google Feed to Google Discover, updated the design, and adding more features.[75]

Discover can be found on a tab in the Google app and by swiping left on the home screen of certain Android devices. As of 2019, Google will not allow political campaigns worldwide to target their advertisement to people to make them vote.[76]

Search Generative Experience

At the 2023 Google I/O event in May, Google unveiled Search Generative Experience (SGE), an experimental feature in Google Search available through Google Labs which produces AI-generated summaries in response to search prompts.[77] This was part of Google's wider efforts to counter the unprecedented rise of generative AI technology, ushered by OpenAI's launch of ChatGPT, which sent Google executives to a panic due to its potential threat to Google Search.[78] Google added the ability to generate images in October.[79]

Redesigns

Product Sans, Google's typeface since 2015

In late June 2011, Google introduced a new look to the Google home page in order to boost the use of the Google+ social tools.[80]

One of the major changes was replacing the classic navigation bar with a black one. Google's digital creative director Chris Wiggins explains: "We're working on a project to bring you a new and improved Google experience, and over the next few months, you'll continue to see more updates to our look and feel."[81] The new navigation bar has been negatively received by a vocal minority.[82]

In November 2013, Google started testing yellow labels for advertisements displayed in search results, to improve user experience. The new labels, highlighted in yellow color, and aligned to the left of each sponsored link help users differentiate between organic and sponsored results.[83]

On December 15, 2016, Google rolled out a new desktop search interface that mimics their modular mobile user interface. The mobile design consists of a tabular design that highlights search features in boxes. and works by imitating the desktop Knowledge Graph real estate, which appears in the right-hand rail of the search engine result page, these featured elements frequently feature Twitter carousels, People Also Search For, and Top Stories (vertical and horizontal design) modules. The Local Pack and Answer Box were two of the original features of the Google SERP that were primarily showcased in this manner, but this new layout creates a previously unseen level of design consistency for Google results.[84]

Smartphone apps

Google offers a "Google Search" mobile app for Android and iOS devices.[85] The mobile apps exclusively feature Google Discover and a "Collections" feature, in which the user can save for later perusal any type of search result like images, bookmarks or map locations into groups.[86] Android devices were introduced to a preview of the feed, perceived as related to Google Now, in December 2016,[87] while it was made official on both Android and iOS in July 2017.[88][89]

In April 2016, Google updated its Search app on Android to feature "Trends"; search queries gaining popularity appeared in the autocomplete box along with normal query autocompletion.[90] The update received significant backlash, due to encouraging search queries unrelated to users' interests or intentions, prompting the company to issue an update with an opt-out option.[91] In September 2017, the Google Search app on iOS was updated to feature the same functionality.[92]

In December 2017, Google released "Google Go", an app designed to enable use of Google Search on physically smaller and lower-spec devices in multiple languages. A Google blog post about designing "India-first" products and features explains that it is "tailor-made for the millions of people in [India and Indonesia] coming online for the first time".[93]

Performing a search

A definition link is provided for many search terms.

Google Search consists of a series of localized websites. The largest of those, the google.com site, is the top most-visited website in the world.[94] Some of its features include a definition link for most searches including dictionary words, the number of results you got on your search, links to other searches (e.g. for words that Google believes to be misspelled, it provides a link to the search results using its proposed spelling), the ability to filter results to a date range,[95] and many more.

Search syntax

Google search accepts queries as normal text, as well as individual keywords.[96] It automatically corrects apparent misspellings by default (while offering to use the original spelling as a selectable alternative), and provides the same results regardless of capitalization.[96] For more customized results, one can use a wide variety of operators, including, but not limited to:[97][98]

  • OR – Search for webpages containing one of two similar queries, such as marathon OR race
  • - (minus sign) – Exclude a word or a phrase, so that "apple -tree" searches where word "tree" is not used
  • "" – Force inclusion of a word or a phrase, such as "tallest building"
  • * – Placeholder symbol allowing for any substitute words in the context of the query, such as "largest * in the world"
  • .. – Search within a range of numbers, such as "camera $50..$100"
  • site: – Search within a specific website, such as "site:youtube.com"
  • define: – Search for definitions for a word or phrase, such as "define:phrase"
  • stocks: – See the stock price of investments, such as "stocks:googl"
  • related: – Find webpages related to specific URL addresses, such as "related:www.wikipedia.org"
  • cache: – Highlights the search-words within the cached pages, so that "cache:www.google.com xxx" shows cached content with word "xxx" highlighted.
  • @ – Search for a specific word on social media networks, such as "@twitter"

Google also offers a Google Advanced Search page with a web interface to access the advanced features without needing to remember the special operators.[99]

Query expansion

Google applies query expansion to submitted search queries, using techniques to deliver results that it considers "smarter" than the query users actually submitted. This technique involves several steps, including:[100]

  • Word stemming – Certain words can be reduced so other, similar terms, are also found in results, so that "translator" can also search for "translation"
  • Acronyms – Searching for abbreviations can also return results about the name in its full length, so that "NATO" can show results for "North Atlantic Treaty Organization"
  • Misspellings – Google will often suggest correct spellings for misspelled words
  • Synonyms – In most cases where a word is incorrectly used in a phrase or sentence, Google search will show results based on the correct synonym
  • Translations – The search engine can, in some instances, suggest results for specific words in a different language
  • Ignoring words – In some search queries containing extraneous or insignificant words, Google search will simply drop those specific words from the query

In 2008, Google started to give users autocompleted search suggestions in a list below the search bar while typing, originally with the approximate result count previewed for each listed search suggestion.[101]

"I'm Feeling Lucky"

Google's homepage includes a button labeled "I'm Feeling Lucky". This feature originally allowed users to type in their search query, click the button and be taken directly to the first result, bypassing the search results page. Clicking it while leaving the search box empty opens Google's archive of Doodles.[102] With the 2010 announcement of Google Instant, an automatic feature that immediately displays relevant results as users are typing in their query, the "I'm Feeling Lucky" button disappears, requiring that users opt-out of Instant results through search settings to keep using the "I'm Feeling Lucky" functionality.[103] In 2012, "I'm Feeling Lucky" was changed to serve as an advertisement for Google services; users hover their computer mouse over the button, it spins and shows an emotion ("I'm Feeling Puzzled" or "I'm Feeling Trendy", for instance), and, when clicked, takes users to a Google service related to that emotion.[104]

Tom Chavez of "Rapt", a firm helping to determine a website's advertising worth, estimated in 2007 that Google lost $110 million in revenue per year due to use of the button, which bypasses the advertisements found on the search results page.[105]

Special interactive features

Besides the main text-based search-engine function of Google search, it also offers multiple quick, interactive features. These include, but are not limited to:[106][107][108]

  • Calculator
  • Time zone, currency, and unit conversions
  • Word translations
  • Flight status
  • Local film showings
  • Weather forecasts
  • Population and unemployment rates
  • Package tracking
  • Word definitions
  • Metronome
  • Roll a die
  • "Do a barrel roll" (search page spins)
  • "Askew" (results show up sideways)

"OK Google" conversational search

During Google's developer conference, Google I/O, in May 2013, the company announced that users on Google Chrome and ChromeOS would be able to have the browser initiate an audio-based search by saying "OK Google", with no button presses required. After having the answer presented, users can follow up with additional, contextual questions; an example include initially asking "OK Google, will it be sunny in Santa Cruz this weekend?", hearing a spoken answer, and reply with "how far is it from here?"[109][110] An update to the Chrome browser with voice-search functionality rolled out a week later, though it required a button press on a microphone icon rather than "OK Google" voice activation.[111] Google released a browser extension for the Chrome browser, named with a "beta" tag for unfinished development, shortly thereafter.[112] In May 2014, the company officially added "OK Google" into the browser itself;[113] they removed it in October 2015, citing low usage, though the microphone icon for activation remained available.[114] In May 2016, 20% of search queries on mobile devices were done through voice.[115]

In addition to its tool for searching web pages, Google also provides services for searching images, Usenet newsgroups, news websites, videos (Google Videos), searching by locality, maps, and items for sale online. Google Videos allows searching the World Wide Web for video clips.[116] The service evolved from Google Video, Google's discontinued video hosting service that also allowed to search the web for video clips.[116]

In 2012, Google has indexed over 30 trillion web pages, and received 100 billion queries per month.[117] It also caches much of the content that it indexes. Google operates other tools and services including Google News, Google Shopping, Google Maps, Google Custom Search, Google Earth, Google Docs, Picasa (discontinued), Panoramio (discontinued), YouTube, Google Translate, Google Blog Search and Google Desktop Search (discontinued[118]).

There are also products available from Google that are not directly search-related. Gmail, for example, is a webmail application, but still includes search features; Google Browser Sync does not offer any search facilities, although it aims to organize your browsing time.

Energy consumption

In 2009, Google claimed that a search query requires altogether about 1 kJ or 0.0003 kW·h,[119] which is enough to raise the temperature of one liter of water by 0.24 °C. According to green search engine Ecosia, the industry standard for search engines is estimated to be about 0.2 grams of CO2 emission per search.[120] Google's 40,000 searches per second translate to 8 kg CO2 per second or over 252 million kilos of CO2 per year.[121]

Google Doodles

On certain occasions, the logo on Google's webpage will change to a special version, known as a "Google Doodle". This is a picture, drawing, animation, or interactive game that includes the logo. It is usually done for a special event or day although not all of them are well known.[122] Clicking on the Doodle links to a string of Google search results about the topic. The first was a reference to the Burning Man Festival in 1998,[123][124] and others have been produced for the birthdays of notable people like Albert Einstein, historical events like the interlocking Lego block's 50th anniversary and holidays like Valentine's Day.[125] Some Google Doodles have interactivity beyond a simple search, such as the famous "Google Pac-Man" version that appeared on May 21, 2010.

Criticism

Privacy

Google has been criticized for placing long-term cookies on users' machines to store preferences, a tactic which also enables them to track a user's search terms and retain the data for more than a year.[126]

Since 2012, Google Inc. has globally introduced encrypted connections for most of its clients, to bypass governative blockings of the commercial and IT services.[127]

Complaints about indexing

In 2003, The New York Times complained about Google's indexing, claiming that Google's caching of content on its site infringed its copyright for the content.[128] In both Field v. Google and Parker v. Google, the United States District Court of Nevada ruled in favor of Google.[129][130]

Child sexual abuse

A 2019 New York Times article on Google Search showed that images of child sexual abuse had been found on Google and that the company had been reluctant at times to remove them.[131]

January 2009 malware bug

A screenshot of the error of January 31, 2009

Google flags search results with the message "This site may harm your computer" if the site is known to install malicious software in the background or otherwise surreptitiously. For approximately 40 minutes on January 31, 2009, all search results were mistakenly classified as malware and could therefore not be clicked; instead a warning message was displayed and the user was required to enter the requested URL manually. The bug was caused by human error.[132][133][134][135] The URL of "/" (which expands to all URLs) was mistakenly added to the malware patterns file.[133][134]

Possible misuse of search results

In 2007, a group of researchers observed a tendency for users to rely exclusively on Google Search for finding information, writing that "With the Google interface the user gets the impression that the search results imply a kind of totality. ... In fact, one only sees a small part of what one could see if one also integrates other research tools."[136]

In 2011, Google Search query results have been shown by Internet activist Eli Pariser to be tailored to users, effectively isolating users in what he defined as a filter bubble. Pariser holds algorithms used in search engines such as Google Search responsible for catering "a personal ecosystem of information".[137] Although contrasting views have mitigated the potential threat of "informational dystopia" and questioned the scientific nature of Pariser's claims,[138] filter bubbles have been mentioned to account for the surprising results of the U.S. presidential election in 2016 alongside fake news and echo chambers, suggesting that Facebook and Google have designed personalized online realities in which "we only see and hear what we like".[139]

FTC fines

In 2012, the US Federal Trade Commission fined Google US$22.5 million for violating their agreement not to violate the privacy of users of Apple's Safari web browser.[140] The FTC was also continuing to investigate if Google's favoring of their own services in their search results violated antitrust regulations.[141]

Payments to Apple

In a November 2023 disclosure, during the ongoing antitrust trial against Google, an economics professor at the University of Chicago revealed that Google pays Apple 36% of all search advertising revenue generated when users access Google through the Safari browser. This revelation reportedly caused Google's lead attorney to cringe visibly. The revenue generated from Safari users has been kept confidential, but the 36% figure suggests that it is likely in the tens of billions of dollars.

Both Apple and Google have argued that disclosing the specific terms of their search default agreement would harm their competitive positions. However, the court ruled that the information was relevant to the antitrust case and ordered its disclosure. This revelation has raised concerns about the dominance of Google in the search engine market and the potential anticompetitive effects of its agreements with Apple.[142]

Big data and human bias

Google search engine robots are programmed to use algorithms that understand and predict human behavior. The book, Race After Technology: Abolitionist Tools for the New Jim Code[143] by Ruha Benjamin talks about human bias as a behavior that the Google search engine can recognize. In 2016, some users google searched "three Black teenagers" and images of criminal mugshots of young African American teenagers came up. Then, the users searched "three White teenagers" and were presented with photos of smiling, happy teenagers. They also searched for "three Asian teenagers", and very revealing photos of Asian girls and women appeared. Benjamin concluded that these results reflect human prejudice and views on different ethnic groups. A group of analysts explained the concept of a racist computer program: "The idea here is that computers, unlike people, can't be racist but we're increasingly learning that they do in fact take after their makers ... Some experts believe that this problem might stem from the hidden biases in the massive piles of data that the algorithms process as they learn to recognize patterns ... reproducing our worst values".[143]

Trademark

As people talk about "googling" rather than searching, the company has taken some steps to defend its trademark, in an effort to prevent it from becoming a generic trademark.[144][145] This has led to lawsuits, threats of lawsuits, and the use of euphemisms, such as calling Google Search a famous web search engine.[146]

Discontinued features

Translate foreign pages

Until May 2013, Google Search had offered a feature to translate search queries into other languages. A Google spokesperson told Search Engine Land that "Removing features is always tough, but we do think very hard about each decision and its implications for our users. Unfortunately, this feature never saw much pick up".[147]

Instant search

Instant search was announced in September 2010 as a feature that displayed suggested results while the user typed in their search query, initially only in select countries or to registered users.[148] The primary advantage of the new system was its ability to save time, with Marissa Mayer, then-vice president of search products and user experience, proclaiming that the feature would save 2–5 seconds per search, elaborating that "That may not seem like a lot at first, but it adds up. With Google Instant, we estimate that we'll save our users 11 hours with each passing second!"[149] Matt Van Wagner of Search Engine Land wrote that "Personally, I kind of like Google Instant and I think it represents a natural evolution in the way search works", and also praised Google's efforts in public relations, writing that "With just a press conference and a few well-placed interviews, Google has parlayed this relatively minor speed improvement into an attention-grabbing front-page news story".[150] The upgrade also became notable for the company switching Google Search's underlying technology from HTML to AJAX.[151]

Instant Search could be disabled via Google's "preferences" menu for those who didn't want its functionality.[152]

The publication 2600: The Hacker Quarterly compiled a list of words that Google Instant did not show suggested results for, with a Google spokesperson giving the following statement to Mashable:[153]

There are several reasons you may not be seeing search queries for a particular topic. Among other things, we apply a narrow set of removal policies for pornography, violence, and hate speech. It's important to note that removing queries from Autocomplete is a hard problem, and not as simple as blacklisting particular terms and phrases.

In search, we get more than one billion searches each day. Because of this, we take an algorithmic approach to removals, and just like our search algorithms, these are imperfect. We will continue to work to improve our approach to removals in Autocomplete, and are listening carefully to feedback from our users.

Our algorithms look not only at specific words, but compound queries based on those words, and across all languages. So, for example, if there's a bad word in Russian, we may remove a compound word including the transliteration of the Russian word into English. We also look at the search results themselves for given queries. So, for example, if the results for a particular query seem pornographic, our algorithms may remove that query from Autocomplete, even if the query itself wouldn't otherwise violate our policies. This system is neither perfect nor instantaneous, and we will continue to work to make it better.

PC Magazine discussed the inconsistency in how some forms of the same topic are allowed; for instance, "lesbian" was blocked, while "gay" was not, and "cocaine" was blocked, while "crack" and "heroin" were not. The report further stated that seemingly normal words were also blocked due to pornographic innuendos, most notably "scat", likely due to having two completely separate contextual meanings, one for music and one for a sexual practice.[154]

On July 26, 2017, Google removed Instant results, due to a growing number of searches on mobile devices, where interaction with search, as well as screen sizes, differ significantly from a computer.[155][156]

Instant previews

"Instant previews" allowed previewing screenshots of search results' web pages without having to open them. The feature was introduced in November 2010 to the desktop website and removed in April 2013 citing low usage.[157][158]

Dedicated encrypted search page

Various search engines provide encrypted Web search facilities. In May 2010 Google rolled out SSL-encrypted web search.[159] The encrypted search was accessed at encrypted.google.com[160] However, the web search is encrypted via Transport Layer Security (TLS) by default today, thus every search request should be automatically encrypted if TLS is supported by the web browser.[161] On its support website, Google announced that the address encrypted.google.com would be turned off April 30, 2018, stating that all Google products and most new browsers use HTTPS connections as the reason for the discontinuation.[162]

Real-Time Search

Google Real-Time Search was a feature of Google Search in which search results also sometimes included real-time information from sources such as Twitter, Facebook, blogs, and news websites.[163] The feature was introduced on December 7, 2009[164] and went offline on July 2, 2011, after the deal with Twitter expired.[165] Real-Time Search included Facebook status updates beginning on February 24, 2010.[166] A feature similar to Real-Time Search was already available on Microsoft's Bing search engine, which showed results from Twitter and Facebook.[167] The interface for the engine showed a live, descending "river" of posts in the main region (which could be paused or resumed), while a bar chart metric of the frequency of posts containing a certain search term or hashtag was located on the right hand corner of the page above a list of most frequently reposted posts and outgoing links. Hashtag search links were also supported, as were "promoted" tweets hosted by Twitter (located persistently on top of the river) and thumbnails of retweeted image or video links.

In January 2011, geolocation links of posts were made available alongside results in Real-Time Search. In addition, posts containing syndicated or attached shortened links were made searchable by the link: query option. In July 2011 Real-Time Search became inaccessible, with the Real-Time link in the Google sidebar disappearing and a custom 404 error page generated by Google returned at its former URL. Google originally suggested that the interruption was temporary and related to the launch of Google+;[168] they subsequently announced that it was due to the expiry of a commercial arrangement with Twitter to provide access to tweets.[169]
