Pixalate uses its proprietary algorithms to measure quality metrics, including invalid traffic (IVT or ad fraud), made for advertising (MFA) risk, brand safety, ad density, viewability, reach, and more. The Publisher Trust Index spans rankings for 235+ countries across all four global regions: North America, EMEA, APAC, and LATAM, and provides breakdowns by 20+ different IAB taxonomy website categories.
