What is Ad Stacking?
Ad stacking is a type of mobile display and impression fraud where mobile apps or websites stack multiple ads beneath one another in a single ad placement. While only the top ad is visible with its impression actually served, multiple advertisers are billed for the impression. If a user clicks the top ad, a click will be registered for all ads on the stack. For more on addressing ad stacking fraud, see display fraud.
Identifying Ad Stacking Fraud:
Ad stacking can be identified in instances in which multiple ad click engagements are reported under the exact same time stamp for a single ad placement.
