CESP has just released its audit report of Nielsen’s Digital Ad Ratings (DAR) solution

CESP has sent Nielsen and Médiamétrie its audit report on the Digital Ad Ratings (DAR) solution. This audit was carried out at the request of CESP’s internet, television and press committees. It covers the period from March 2024 to March 2025, solely within the scope of the Open Web.

CESP considers that DAR offers the indistry an industrialised solution based on relevant methodological principles such as the use of an ID Graph and the integration of local third-party data. However, further developments are needed to take full advantage of the integration of local data providers and to enhance the robustness and accuracy of the results.
