What is Impression Fraud?
Impression fraud is a collective term for fraudulent actions that target advertisers who buy traffic on a CPM basis. These actions aim to report impressions, although actually, no user sees an ad. In other words, the goal of impression fraud is to bill advertisers for impressions that never have been delivered.
These are typical types of impression fraud:
- Ad Stacking
- Pop Unders
Synonyms:
Mobile Display Fraud
