#1 Panda Update: February, 2011
18 months ago you could almost hear the sound of thousands, maybe even millions, of low paid writers churning out web content for content farm like Demand Studios and eHow.
These low quality articles were dominating all kinds of keywords without providing any value; the Panda update would change all of that for good.
