After almost a year since it’s launch under the Google label, former Urchin traffic analyzer, now Google Analytics runs at full capacity:

• No more invitations needed for an account
• A maximum of 50 websites to monitor

Still, this a too complex tool for the most website owners and I recommend for bloggers to use Performancing Metrics

Bonus Tip:

If you own multiple blogs, install Performancing tracking code and make the RSS feed public. Then go to Netvibes, create a new tab and add all the feeds from the websites tracked. The result will be a nice real time control panel for all of your blogs
