9 million impressions in overdelivery
I won’t say which site this was, but one of the sites on my plan made a mistake and served impressions for a unit outside of the flight window. Usually when a site overdelivers, it’s by under 10% of contracted impressions. However, this site delivered 9 million. Their CPM is around $5, making that $45,000 worth of impressions that they gave away. The sad thing is that the advertiser probably doesn’t care, or may even be pissed off about it. Too bad I couldn’t pocket any of that.
