IAB published the Podcast Measurement Guidelines last year. Those guidelines provided the first true industry-wide guidelines for measuring ad deliveries in podcasts. This year, IAB published the IAB Podcast Measurement Technical Guidelines Version 2.0.
The new guidelines provide a recommended process for generating audience and downloading metrics, with information on:
Filtering for uniqueness
Eliminating pre-load requests
Eliminating potential bots and bogus requests
Applying thresholds for what gets counted
And more best practices. The Version 2.0 guidelines are long and detailed and well worth reading. The document was developed by the IAB Tech Lab Podcast Technical Working Group, which was led by Steve Mulder (NPR) and Amit Shetty (IAB Tech Lab) The Group included:
