Google Analytics was a flop for me. I could never get the required code installed in WordPress. Google got overwhelmed with requests for this service and quit accepting new accounts. I think they grossly underestimated demand for this service.
I got frustrated trying to install the code in the version of WP that I refuse to upgrade to any of the new theme based releases, I like my current css. So I went and checked out statcounter.com. It automatically emails me all of the stats I need each week. The free version is limited to analyzing the last 100 visitations in the log but I don’t foresee needing to gather any information about any more than my last 100 visitors. So analyze this google – I’ll come back when Analytics tracking code is easier to integrate into WP 1.2.1 and you can track the stats of current subscribers a little faster.
