Microsoft adCenter Bug Makes Advertisers Pay Thousands

Posted by @ 7:25 pm

If you have a Microsoft adCenter account, you may have seen a major spike in your cost-per-click prices over the weekend, with the system suffering from a major bug. First reports emerged on SEroundtable with close attention to a thread on WebmasterWorld.

The post includes quotes from different users reporting on how the bug has affected them. One user reports:

“They charged me $5.10/click on something that is clearly set at $0.44/click! My daily spend increased almost 10-fold from $140 to over $1350 yesterday!”

The post also shows screenshots of a customers account, showing a dramatic increase in the average CPC (cost-per-click) even though the bid is set to only 50c.

The hive of activity online was quickly picked up by Microsoft who were swift to act on a solution to the problem. From the Microsoft adCenter blog:

“Some of our adCenter advertisers are seeing high cost-per-click (CPC) and spend amounts in their accounts. I will update this post with more information as soon as I have it, but I wanted to let you know that this issue is now resolved and those of you who were overcharged, we’re working on a plan to credit your accounts for over-charges as soon as possible.”

To Microsoft’s credit, they were quick to act and have now automatically refunded all accounts that were overcharged. If you were affected by this bug, let us know what happened!
