Layer ads (for "layer ads", also English Hover Ads called) are a form of Internet advertising , when ads about the actual content of a site are displayed. Parts of the underlying content are covered. In addition to text, you also use elements such as animations, images or videos.

In contrast to traditional pop- ups, layer ads are not separate browser windows, but rather layers embedded directly on the original page. This type of advertising placement is becoming increasingly widespread because it cannot be prevented by the pop-up blockers integrated in web browsers .

Strategies

Some creators try different methods to force the user to click the advertisements or to keep the user's attention for a longer period of time. One method is to graphically hide the closing control. In another variant, the buttons of the advertising window are labeled or arranged contrary to the conventions, so that the user's page opens by clicking on a control element that is confusingly similar to the one that is normally used to close a window. Another method is to trigger the control element when you point it with the mouse pointer (hover). Since it is arranged in such a way that there is a conventional advertising banner of the same advertising customer underneath, the web link of the advertising banner is activated by the click made by the user and the website of the advertising customer is opened.

Prevention of display

The display of layer ads can be prevented by deactivating the corresponding JavaScript files. Browsers generally allow all JavaScript functionality to be switched off, but partial blocking of certain scripts is only possible with browser extensions such as NoScript .

There are also extensions for some web browsers which only block the specific JavaScripts when loading a website that are required for displaying the layer advertising. Since layered advertising is usually provided by advertising companies specializing in Internet advertising, the advertising scripts can be identified using freely available filter lists and thus prevent the web browser from loading. URL filters for image and flash material from advertising companies are often included in these filter lists.

Opera contains a corresponding filter function by default, you only need the URL list. For Mozilla Firefox and Google Chrome there is an extension such as B. Adblock and uBlock , which works according to the above principle. There are similar extensions for other web browsers.
