Does anyone else believe that the "Panda algorithm updates" are bullshit and that they are just the results from the massive manual rating teams Google pays to constantly evaluate and re-evaluate search results? I think there is a small amount of input from some new algorithmic change, but that most of the downward movement you see after a "Panda update" comes from manual ratings. It's widely known that a huge percentage all searches are for a relatively small number of terms. It's more than logistically possible to manually review the first several results for all these terms. I'm sure a lot of you have seen the actual training document that Google's contractor for these ratings uses coolbubba .com/ GoogleRatingGuidelines .pdf If you really read the document, it's made clear to the reviewers that their input will directly affect a website's SERP. There are entire sections of the document dedicated to teaching the reviewers how to evaluate a website in the exact same way Google claims Panda works. Yeah, that's right, they're even instructing the raters to manually seek out duplicate content That sort of flies in the face of the idea that Google's algorithm is a master at automatically finding copied content. Obviously they don't have an algorithmic solution, otherwise they wouldn't be paying humans to perform quotation searches to check for duplicate content. What a joke! And it's obvious why Google pays a third party contractor to perform these reviews, rather than simply have an in-house team do it - they have to shield themselves from anti-trust violations! If they performed these ratings themselves, they could be sued by the government for manipulating the market! While other search engines do use these outside contractors too, I think Google is simply better at weighting and applying the results to their SERPS. Their big breakthrough was probably finding an algorithm that could confirm, weight, and incorporate manual ratings, and this is what they call "Panda".
