What Impression Fraud means

Impression fraud involves artificially inflating ad impression counts through techniques like bot traffic, ad stacking (layering invisible ads), pixel stuffing (rendering ads in tiny invisible frames), domain spoofing, and ad injection. This type of fraud primarily affects CPM-based campaigns where advertisers pay per thousand impressions. The Media Rating Council (MRC) and Interactive Advertising Bureau (IAB) have established standards for valid impressions, and platforms implement traffic quality filters to detect and exclude invalid impressions. Third-party verification companies like IAS, DoubleVerify, and MOAT provide additional fraud detection. Advertisers can protect themselves by monitoring viewability rates, suspicious traffic patterns, and using verified inventory sources.
