Google has announced its new “Caffeine” architecture and has had testers using and reviewing. So far there have been both good and bad reviews, but one in particular stands out. Caffeine seems to be more of a changed algorithm rather than a totally new architecture. If this is true, it is really no different from the old Google.
While a final version of Caffeine has not yet been launched, some are speculating that it is more of a diversion to keep people from engines like Bing. Even so, however, placement on Caffeine is different and could affect SEO to some degree. For some searches, placement dropped several spots between the two types of Google, something that could happen with every change in algorithm on the old engine.
