Nielsen Digital Ad Ratings

Industry-leading third-party digital ad measurement solution with widespread adoption among major advertisers, agencies, and publishers

Nielsen Digital Ad Ratings (DAR) is a measurement and analytics product from Nielsen, the global measurement and data analytics company. Launched in 2010, Digital Ad Ratings provides independent, third-party verification of digital advertising campaign audience metrics across desktop, mobile, and connected TV platforms. The product measures who actually saw digital ads, comparing campaign delivery against intended target audiences using Nielsen's proprietary panel data and census-level measurement capabilities. DAR has become an industry standard for digital ad measurement, helping advertisers, agencies, and publishers verify that campaigns reach their intended audiences with accurate demographic information. The product addresses a critical need in the digital advertising ecosystem for independent verification of ad delivery and audience composition, moving beyond basic impressions to provide person-level measurement that mirrors Nielsen's traditional TV ratings methodology. Nielsen DAR integrates with major digital platforms including Facebook, Google, Twitter, Snapchat, and numerous ad servers and DSPs, making it a ubiquitous measurement solution across the digital advertising landscape.
