Host-read ads continued to be the preferred ad type, constituting nearly two-thirds of all podcast advertising. Direct response campaigns were still the most popular ad type, but are decreasing in popularity, as brand awareness and branded content ad types rose in use. Cost-per-thousand was by far the most dominant pricing method.

“Today’s technology has created an audio-first environment where audio is the preferred interaction—and consumers have put podcasts front-and-center,” said Anna Bager, Executive Vice President, Industry Initiatives, IAB. “Podcast storytelling is deeply engaging and provides marketers with a brand safe environment that enhances the appeal to advertisers.
