Feels like at least once a week, I write about how Google AdSense has reporting issues. Today, I spotted a WebmasterWorld thread that has dozens of AdSense publishers complaining that the reports seem off again.

Specifically, the issues are as follows:

Impressions are twice the normal expected amountClick through rates are about half of the normal expected amountEarnings are (obviously) on target with what is expected

In summary, many publishers are noticing high numbers in impression reporting, but lower in the actual click through rate, which leads to the same earning reports as they historically see.

AdSenseAdvisor said a few hours ago:

Forum discussion at WebmasterWorld.

Update: This is now fixed but ads were double or tripled served in some cases.
