I have a questios,
I know for a fact that some of my banner are not up and I'm still getting impressions for them. How come this happens?
Impression events occur when the ad is served, so I don't see any way that you could have impression events for an ad that was never served. We store all of the underlying data when an ad is served including the date/time, page URL, etc. Please contact us and let us know which is the ad in question. We can then audit the underlying raw event data for you and let you know what page the ad was served to. Thanks!
