Google announced it's making changes to its search algorithm to demote "notorious" piracy websites in search results. Additionally, Google will also make changes to its autocomplete feature to prevent piracy suggestions from showing up in the autocomplete results list:
In the place of these unofficial or illegal links — which often rank above legal, commercial sites — Google will now show direct links to Amazon, Netflix, Spotify, and other “official” sites. Furthermore, Google will more aggressively prune the results that pop up via autocomplete so that they’re in-line with DMCA takedown notices (i.e. Google will no longer prompt you with “free download” when you start typing the name of a movie).
