Giving itself a taste of its own medicine, Google is banning some of its own pages for inadvertently using a forbidden search engine optimization tactic. After being hounded by the search engine optimization community for alleged "cloaking," Google investigated the claims, finding that indeed some of its pages were cloaked, according to SearchEngineWatch. Technically, there are some approved uses of cloaking, but Google's reaction seems more geared to quieting the ruckus that developed on search-oriented bulletin boards. SearchEngineLowdown notes that neither of the two apparent possible scenarios - that Google did it purposefully, or that Google's own detection mechanisms failed to note the cloaking on its own site - do not reflect well on the firm.
