A WebmasterWorld thread and adCenter Forum thread have reports that Microsoft adCenter is reporting that clicks are not being charged. Yes, the adCenter reports are showing a $0.00 cost per click in their reports.
Here are some of the reports from the advertisers:
Whilst I'd love this to be real, looks like a bug as clicks priced at 0.00 aren't so common!
No matter which report I call up - I'm not being charged (according to the reports) for clicks.
Yes, I'm seeing the same thing. All reports yesterday and today show $0.00.
I'm guessing we'll see this resolved Monday morning. On the other hand, it might be Microsoft's way of thanking us for our business in 2009 ;)
Many suspect this is some sort of reporting glitch. I suspect so to. But it would be nice if it was not a glitch and Microsoft gave some of their advertisers a nice New Years bonus.
Update: I guess this is a bug, @adCenter tweeted:
Update 2: Tuesday, January 5th at 11am (EST) @adCenter tweeted the issue has been resolved.
