Starting next week, we will begin taking into account a new signal in our rankings: the number of <a href="//www.google.com/transparencyreport/">valid copyright removal notices</a> we receive for any given site. Sites with high numbers of removal notices may appear lower in our results. This ranking change should help users find legitimate, quality sources of content more easily—whether it’s a song previewed on <a href="http://www.npr.org/music/">NPR’s music website</a>, a TV show on <a href="http://www.hulu.com/">Hulu</a> or new music streamed from <a href="http://www.spotify.com/">Spotify</a>.<br /> <br /> Since we re-booted our copyright removals over two years ago, we’ve been given much more data by copyright owners about infringing content online. In fact, we’re now receiving and processing more copyright removal notices every day than we did in all of 2009—<a href="//www.google.com/transparencyreport/removals/copyright/">more than 4.3 million URLs in the last 30 days alone</a>. We will now be using this data as a signal in our search rankings. <br /> <br /> Only copyright holders know if something is authorized, and only courts can decide if a copyright has been infringed; Google cannot determine whether a particular webpage does or does not violate copyright law. So while this new signal will influence the ranking of some search results, we won’t be removing any pages from search results unless we <a href="http://support.google.com/bin/static.py?hl=en&ts=1114905&page=ts.cs">receive</a> a valid copyright removal notice from the rights owner. And we’ll continue to provide "<a href="http://www.chillingeffects.org/question.cgi?QuestionID=132">counter-notice</a>" tools so that those who believe their content has been wrongly removed can get it reinstated.
