It's official, last week mr.pageRank himself the new ceo of the Big G launched a net wide algorithm change that supposedly started dropping content blog farms from the serp rankings in an effort for original quality site and information to rise. It has been known that sites like AOL, and others have been using their trends feed and crafting articles behind it in an effort to get high volume traffic from the heavily SEO'd content they have on their "content networks". In other words siphoning traffic from the serps with trends splogs. It is said to have been a 11.8% change, I havent noticed any negative effects on any of my sites. So far so good. Hope none of you suffered any drastic loss.
