I’m very impressed with Google Analytics so far.I was thinking of buying urchin for my Ecommerce Consultancy at one point, as I thought it was pretty good. Google obviously thought so too, since they went and bought the company so its especially nice to get it for free. I really like the overlays, as shown on my site (above). I tried to do a similar thing when I was at Amazon to calculate the value of a placement on various parts of the amazon homepage – it worked well, but I did it manually and it took a while to do. This is great to have, and even better for my Ecommerce clients.
