Ad Stacking

Ad Stacking is a fraudulent practice where multiple ads are layered on top of each other in a single placement, with only the top ad visible. Advertisers still pay for all impressions, even though most are never seen by users. This harms advertisers by wasting budgets and lowers publisher credibility. Identifying and blocking ad stacking is crucial for maintaining trust and ensuring media quality in programmatic advertising.
