Users of the AdSense reports inside of Google Analytics may have noticed that there have been discrepancies between the AdSense reports in Google Analytics and AdSense since March 16th. We’re aware of the issue and a fix is being rolled out at this time. The cause of the issue is not related to the new version of Google Analytics.
Update: 3/22/2011 5:15pm PST - A fix for this issue was released early this morning. It will take a few more hours for the fix reach all users. AdSense reports should be working normally after that. Unfortunately, we are not able to reprocess the data that was affected by this issue.
