Inside Google points to VisitorVille Intelligence, a firm that sells a web log analysis product (previously covered by MarketingVOX in June), as well an aggregated data service showing how web visitation habits differ from company to company. Interestingly, some examples used in its marketing materials show that Microsoft's own workers use Google's search engine over the MSN equivalent by about a three-to-one ratio. Yahoo workers appear to use Google over their own product by a two-to-one ratio.
