Despite some bad things I’ve heard about Google Analytics, my first impressions about it is that it’s an excellent tool. I’ve had used AWStats and Webalizer before, and I’ve had to say Google Analytics somewhat ate them all right from the front overview page:
You’ll immediately notice that the site still has low number of visitors, even there’s no history data since I’ve just started using it only very recently… not to mention that the site itself is also new. 😉 But the point is that Google Analytics works and the reports are very useful. Using it is also very easy, too, just sign up then copy-paste the generated code into all of your pages (or your footer HTML template), and you’re done.
