Google reaction

In one of Google's promotional videos for search published in the summer of 2010, the majority of the links available were reported to be produced at content farms.^[12] In late February, 2011, Google announced it was adjusting search algorithms significantly to "provide better rankings for high-quality sites—sites with original content and information such as research, in-depth reports, thoughtful analysis and so on."^[13] This was reported to be a reaction to content farms and an attempt to reduce their effectiveness in manipulating search result rankings.^[14]
