Like with many of Google's popular new products, Google Analytics has to be taken back a step. Google currently is not allowing new users to subscribe to Google Analytics, plus they have removed the add site link for those who have already subscribed. In addition, I get this message when I log in;
Analytics has been successfully installed and data is being gathered now. The demand for Google Analytics surpassed even our highest expectations and as a result some customers may temporarily experience report-update delays. All data continues to be collected and no data has been lost. We are currently adding resources to ensure high-quality service. We apologize for any inconvenience.
I have been looking for the site overlay feature, you know the feature that shows graphical overlays of user clicks and goals. That has also been removed according to a post at WebmasterWorld, message # 180, which has a reply from Google to a Webmaster;
Thank you for your email. The demand for Google Analytics exceeded our expectations. As a result, we have temporarily removed the site overlay tool report. Once we have increased our capacity to process this report effectively, we will add the report back to Google Analytics. You can see link popularity statistics in other Content Optimization reports, such as the "Top Content" report or the "All Navigation" report.
