In case you haven’t heard you no longer need an ‘invite’ or have to wait to get a google analytics account. It’s now open and free to anyone to instantly create an account.
Google analytics is the result of Google’s purchase of urchin, a pretty decent web stats (ok, fine analytics) which previously was pretty pricey if you wanted to deploy it on your site. The downside is code has to be loaded on every page and it then calls a link out to google and stores your data there. Honestly, I enjoy it. When comparing Google’s analytics to our own Smarterstats install, I think you’ll find they both have their advantages and disadvantages, however smarterstats I think provides more in depth information where google provides a nice overview.
