Google Analytics offers a weath of possibilities when one wants to know all about a website. The only problem I see is that it is a commercial product that Google wan'ts to promote and when you use it and like it it might cause a problem of becoming dependent on the system. They made the analyses for free when your site doesn't generate too much traffic. You can monitor several sites from one console. Webdesignes and webmasters for sure will love this tool but eventually will need a subscription to have access to the data. But I must confess, the interface Google Analytics has designed is a fantastic tool for sure.
Off course I started the tracking tool from Google Analytics also on this blog. We will see what it bring and I will report on it later too.
