Google announced that they will be changing their search algorithm in order to filter out lower quality content. It is expected that this will affect nearly 12 percent of all U.S. searches (roughly 1.4 billion searches a month) and will negatively impact content farms like Demand Media, Examiner.com and Yahoo’s Associated Content.

“Our goal is simple: to give people the most relevant answers to their queries as quickly as possible,” wrote Google Fellow Amit Singhal and principal engineer Matt Cutts. “So, we’re very excited about this new ranking improvement because we believe it s a big step in the right direction of helping people find ever higher quality in our results. We’ve been tackling these issues for more than a year and working on this specific change for the past few months. And we’re working on many more updates that we believe will substantially improve the quality of the pages in our results.”
