If you’re one of the many AdSense publishers who recently received a notice from Google about rejected ad requests… well, never mind. Google says it’s a known bug that it’s working to resolve.

Several days ago, publishers began coming to forums saying they’d received a notice saying, “You have rejected ad requests, which will result in lost revenue.” After much confusion and commiseration, it turns out that the problem was a change from Google that had unexpected consequences.

According to Google: “We recently changed the way our system surfaces alerts related to rejected ad requests. This has resulted in some publishers seeing an alert in their AdSense accounts about needing to fix rejected ad requests, though no action is required on their part.”

Google estimates that upwards of 90% of those who received this notice can disregard it, but suggests they follow the link to the help center to make sure that they are in compliance with Google’s guidelines.

The most common causes for legitimate rejected ad requests come from publishers nestling AdSense code within multiple frames or using a supply side platform (ad server or yield manager) that isn’t sending site information to Google.
