Unfortunately, the copyrighted content is illegaly copied all too much on the web. Any author faces the fact that his or her original texts are being stolen: the text of a newly created article can be copied on some web page over days or even hours after the article has been created. The websites stealing the content in this way usually claim that it was "taken from open sources" or "uploaded by one of the users". The stolen content can be used to attract search engine users to a web page and the resulting traffic can be converted to money. This is the main reason for such 'borrowing'. The ability to identify the original texts and rank the corresponding web pages higher than the pages containing copied materials is a crucial property of any search engine.

The analyzer of the ranking of original texts uses exact quotation queries to daily monitor the position of 100 marker articles. For these articles, the web sites of copyright holders are known. The analyzer can thus calculate the percentage of queries for which the original text is ranked higher than the copied material.

The queries in this analyzer are fragments from the original article. By default the queries are submitted to the search engines in quotation marks. This way we expect that the only responses found will be the original article and its copies. However the real users rarely rely on quotation marks, so an additional tab estimates the results based on queries submitted without quotation marks.

The search engines are sorted by their ability to rank original texts higher than the copies in the informer of this analyzer.
