Google is now making Google Analytics available free to AdWords users as well as anyone that serves up less than 5 million pages a month (like me). Google Analytics used to be the Urchin statistics package before it was bought out by Google.
Just for fun, I decided to sign up to use it on my yahoo store, since Yahoo! has such shitty statistics tracking. The first thing that became painfully obvious is that Google didn't plan for the popularity of their offer! Just signing up was painfully slow. The pages containing the forms that you have to fill out aere taking several minutes each to get served up.
Once it is working for that site, I'll try adding my other sites as well. Currently I prefer to use awstats to keep track of my stats, but it would be nice if it gave more information about where specific searches are coming from, and which pages they are going to. I'm hoping that GA will help solve that problem for me.
I'm sure there will be plenty of people that are going to have all sorts of conspiracy theories about what Google is going to do with all the information that they collect from this. Personally, I just don't care. If it helps them to see how many people access my sites and actually spend some time looking around, it can't help but to be good for me.
UPDATE: I'm now at 23 hours since I installed it, and it is still giving me the message that I should be getting results within 12 hours. I'm thinking that they REALLY underestimated the response to their offer.
