Google Analytics is one of the most robust offerings by the search giant and it manages to fly under the radar a little bit. It has almost become ubiquitous for a large number of companies that are not prospects for other analytics packages like Omniture, Coremetrics, Webtrends etc. Many will even run it concurrently with these other players that have one distinct and major difference compared to Google’s offering: they cost money.
Now, many people rail against the amount of data that Google has at its disposal as a result of their analytics offering (formerly Urchin). That’s fine and is great fodder for the Google conspiracy theory set, which is a pretty active community. On the street level though it is hard (read: impossible) to find a more robust offering that is free (another bone of contention for Google haters so go ahead and let’er rip).
