IAB Europe has launched its final Connected TV (CTV) Measurement Framework and Transparency Principles to standardize metrics across the industry. This initiative provides a common lexicon for advertising delivery, audience reach, and performance reporting.
Why it matters
The framework aims to increase consistency and accountability in CTV advertising by reducing fragmentation in measurement. By establishing unified standards, the industry seeks to provide clearer insights into campaign effectiveness for stakeholders.
The framework introduces 5 specific transparency principles and covers 3 core measurement areas including delivery, audience, and performance metrics. These standards serve as an update to the taxonomy defined in the Digital Video Framework and Glossary.
