Google Analytics/Google Webmaster Tools

A while ago I started using Google Analytics. It was really easy to set up, and it gives you useful information, like:

1) site usage statistics
2) visitor profile information (like location)
3) browser used
4) Navigation analysis

OK, I agree this is information that you could retrieve with other commercial software. However, Google Analytics provides you with easy-to-read reports, and it's free (of course, you should be willing to share the collected information with Google). You can even build custom reports!!

In fact, I just read something about Google Webmaster Tools. I'll give it a try!
