IAB Europe released its Connected TV Measurement Framework and Transparency Principles to standardize metrics across digital video advertising. The framework defines requirements for delivery, exposure, and performance reporting to ensure consistency.
Why it matters
The framework aims to improve comparability and accountability in CTV markets where inconsistent metrics previously hindered cross-platform analysis. By enforcing standardized definitions, the initiative seeks to simplify reporting for buyers and sellers of digital video.
The new standard introduces 5 transparency principles across 3 distinct measurement areas. These metrics provide a new common language for industry stakeholders, including Amazon Ads, EGTA, and Samsung Ads, to report on delivery, audience exposure, and performance.
The players
IAB Europe
An industry association that develops standards and policy initiatives for the digital advertising ecosystem.
Amazon Ads
A global advertising division of the e-commerce giant that provides performance-based marketing tools for brands.
EGTA
A trade body representing television and radio sales houses in the European media market.
Samsung Ads
An advertising unit that utilizes proprietary data from connected television devices to deliver targeted marketing.
The details
The framework creates a hierarchical measurement structure where ad impressions serve as the foundation for all subsequent data points. Providers must now categorize reach data as either observed or modeled to comply with the transparency principles. The guidelines require stakeholders to disclose methodological constraints and known limitations in their reporting, aligning with the existing Digital Video Framework and Glossary taxonomy.
Timeline
October 1, 2026: IAB Europe released the final CTV measurement framework.
Market Landscape
This framework updates the definitions previously established in the Digital Video Framework and Glossary. It marks a departure from fragmented reporting practices by anchoring all new CTV metrics to this existing industry taxonomy.
Advertisers should review upcoming reporting templates to ensure they align with the new disclosure requirements regarding modeled versus observed reach. Publishers should prepare to categorize their delivery and performance data according to the three core measurement areas defined in the framework.
The takeaway
Standardization efforts in CTV metrics aim to reduce reporting friction, though success depends on broad adoption by major media platforms. Operators should monitor whether their primary ad-tech vendors update their dashboards to explicitly label reach data as observed or modeled as per these principles.
