Self-service data access is still missing from most retail media networks

Key stat: Only 40% of US retail media networks (RMNs) offer self-service sales data, according to Q2 data from Mars United Commerce.

Beyond the chart:

  • Nearly half (48%) of US retail media buyers purchase on-site retail media via self-serve capabilities, according to March 2025 data from Koddi.
  • For networks that do offer self-service, ease of seller onboarding is crucial—over three-quarters (76%) of retail media decision makers worldwide say it's valuable to them.

Use this chart: If you're a marketer or agency leader, pressure your RMN partners to go beyond basic ROAS. Ask about incrementality testing, clean room integrations, and self-serve data access. Measurement maturity is a competitive edge—both for RMNs and advertisers.
