Google Analytics is great. The *only* thing I don’t like is it only updates every 24 hours. Not a huge deal. Also, AWStats and the like are nice because they use web server logs rather than javascript bugs. Some users disable javascript (and thus are not tracked) and adding another request to every page load is a little annoying and (somewhat) user-unfriendly. But log based solutions are trickier to set up properly. I really like Sawmill (sawmill.net) a NOT free log analysis tool (free trial, though). You can download your web logs from your web server and anayze them locally, so you don’t have to figure out how to install something like AWStats — you just need to get your web admin to give you access to download your logs (and ideally, configure them to be a little more verbose than the default). I’ve heard good things about Mint (also non-free) if you have a php-based site. pphlogger is pretty good, too, for the php-capable sites, but also not free and the admin interface is atrocious.
