I'm not concerned with logging for defect fixing, but more for google-like analytics. Does anyone have a killer schema that they use to make analytics easier. I'd prefer to have control over the analytics on my site and am looking for good practices/ideas/implementations.
I would first look at the properties available in the current HttpRequest class such as:
You may also want to record, if applicable:
HttpSessionState.SessionID
You could then log the information you need into a database for every request for later analysis. How you analyse the data depends on what you want to know.
