Google Penguin

from Wikipedia, the free encyclopedia

Google Penguin (also Penguin update ') refers to a published in 2012 update of the algorithm of the search engine Google . This is aimed, among other things, against overly optimized websites, as can occur in the course of search engine optimization .

history

Penguin first became active on April 24, 2012. A small update followed on May 25, 2012, and another update was carried out in October of the same year. Google assigns version numbers for Penguin starting with 1.0. The smaller updates have sequential numbers up to Penguin 1.3 .

A major adaptation called Penguin 2.0 took place on May 22, 2013. According to Matt Cutts and Google, around 2.3% of US search queries were affected. On April 24, 2012, on which the first penguin update was carried out, it was actually approx. 3.1% of the English-language search queries and about 3% of the queries in languages ​​such as German, Chinese and Arabic. In October 2014, the third major algorithm adjustment was carried out with the Penguin 3.0, which affected around 1% of search queries.

On September 23, 2016, Google announced that the Penguin algorithm is part of the core algorithm and therefore now takes place in real time.

Effects

A search engine like Google strives to prevent the manipulation of results and especially their position. Because of this, the exact variables of the search algorithm are unknown. According to Matt Cutts, former head of the web spam team at Google, the content of the website is particularly relevant for a good ranking. Nevertheless, the ranking can be artificially improved. One possibility here is on-page optimization. The content, formatting and source code are optimized so that Google can read the website better. Another method is the generation of backlinks (backlinks), as is the case with off-page optimization.

Over-optimized websites should be punished by Google Penguin. This can be done by lowering the ranking in the search results or even completely removing the website from the search index. The exact parameters that Google Penguin works with are not known. In the statement on the update announced on April 24, 2012, keyword stuffing and unnatural link patterns were specifically mentioned as criteria for detecting web spam. According to Google, around 3% of all search queries were affected by the update.

Previous updates

In February 2011, Google released an update that later became known as Google Panda . This update was directed against websites with poor quality content. Another update appeared in November 2011. Using “Google Freshness”, the topicality of a website was to be included more in the placement. According to Google, 35 percent of all search queries were affected by this update.
