Podcast CPMs reach for new highs at year’s end: AdvertiseCast

In a very interesting set of benchmarks, podcast ad marketplace AdvertiseCast (a subsidiary of Libsyn) released its internal CPM numbers. The metrics include average cost-per-thousand podcast ad impressions for 30-second and 60-second sponsorships, as well as rates for podcasts with different numbers of listeners.

The key trendline is a CPM history for 60-second spots. The graphic below illustrates four trendlines: three show categories based on audience size, and an average. The average ad price (represented by the black line) reached a two-year high ($23.78) in December.

Across all podcasts addressing at least 1,000 listeners, AdvertiseCast’s 60-second CPM ranges from $22-26.
