The Standards
IAB EU
The IAB Europe Retail Media Measurement Standards - along with their compliance table - create a single, consistent way for Retail Media Networks and Ad Tech Providers to measure and report performance. They define core media metrics, attribution rules and shopper insights so advertisers can finally compare networks like-for-like with confidence.

IAB UK
The Retail Media requirements of the IAB UK Gold Standard are based on the IAB EU standards. They set clear requirements for on-site retail media, covering core metrics like impressions, clicks, viewability, video completion and SIVT. They too ensure networks follow consistent, transparent measurement practices so advertisers can trust the data they receive.
