IAB Tech Lab Updates Podcast Measurement Guidelines for Video and Server-Side Logs
Event summary
- IAB Tech Lab released Podcast Technical Measurement Guidelines v2.3 on July 21, 2026, updating measurement practices for open RSS distribution, video podcasts, and server-side log analysis.
- The guidelines are available for public comment until August 19, 2026.
- Key updates include terminology changes from 'listener' to 'podcast consumer', guidance on URL prefix measurement, RSS enclosure URL changes, invalid traffic considerations, and different measurement window approaches.
- Version 3.0, focusing on streaming video podcasts, is in development for a 2027 release.
The big picture
The update reflects the podcast industry's ongoing shift towards more standardized measurement practices as consumption expands across audio and video formats. With server-side log data remaining critical due to limited client-side playback confirmation, these guidelines aim to reduce discrepancies and build trust in podcast advertising metrics. The forthcoming v3.0 guidelines will further address the growing video podcast segment, highlighting the medium's evolving landscape.
