Looking at a tool called SimilarSite but it's rather expensive. In fact, it's priced for a web design or SEO firm rather than a small shop or site owner. The company collates cookie data and can give detailed analytics about who visited what site, queries used, where they come from and where they go, keywords used by site, etc. Seems to be a great webmaster tool for SEO and for market research except it's too expensive. Does anybody use this tool or know of a tool like it that is not so expensive?
