eRETAIL DATA TRUST
The eRetail Data Trust certification ensures transparency and consistency in eRetail end-of-campaign reports.
This interprofessional approach, requested by Union des marques and UDECAM, was developed jointly with all industry stakeholders : advertisers, media agencies, and advertising sales houses. It is based on measurement standards from Alliance Digitale and Illec, published in April 2024.
This certification ensures the transparency and consistency of the calculation method for eight main performance indicators at the end of each eRetail campaign.
| CPM-CPC-CTR | Add-to-Cart Rate |
| Return on Ad Spend (ROAS) | Incremental Return on Ad Spend (I-ROAS) |
| New buyers | On-Site Campaign Reach |
| Attribution Window | Halo Effect |
