ANA issues retail media measurement standards so brands can compare RMNs
The ANA's Retail Media Measurement Standardization report gives brands a checklist for comparing retail media networks: third-party validation, transparency into methods, a fixed 14-day attribution window, and one shared definition of "outcomes." Built with 40+ marketers and feedback from Walmart, Target, CVS and more — but not Amazon — it aims to end "purple to bananas" comparisons.
