Pixalate’s data science team analysed 33B+ global open programmatic impressions across 17M+ websites, Google Play Store and Apple App Store mobile apps, and connected TV (CTV) apps across Roku, Amazon Fire TV, Samsung Smart TV, and Apple TV app stores in August 2025 to compile the global Publisher Trust Indexes.

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.
