Back in August of 2012 Google introduced the original DMCA algorithm – a policy designed to demote sites which have an unusually high number of DMCA takedown requests. On Friday of last week Google announced that they will be updating the DMCA algorithm as a global roll-out.
An improved DMCA demotion signal in Search. In August 2012 we first announced that we would downrank sites for which we received a large number of valid DMCA notices. We’ve now refined the signal in ways we expect to visibly affect the rankings of some of the most notorious sites. This update will roll out globally starting next week.
Furthermore Google has removed various terms from their autocomplete list which would return results with many DMCA demoted sites.
