iHeartMedia is urging advertisers to focus on audience alignment, trusted podcast hosts and campaign measurement as they develop podcast advertising strategies, citing the medium’s growing reach and listener engagement.
Citing Edison Research’s Infinite Dial 2026 report, the company said 58% of Americans consume podcasts monthly. Additionally, iHeartMedia says podcast episodes achieve an average completion rate of 80%. The figures point to an opportunity for marketers to connect with audiences through content they actively choose to hear.
The piece outlines a process for selecting podcast advertising inventory, identifying appropriate audiences and determining which ad formats best support campaign objectives.
Podcast advertising inventory can be purchased directly through
Podcast advertising inventory can be purchased directly through publishers or through advertising networks that represent multiple shows and audiences. Working with a network can provide access to a broader range of programming without requiring advertisers to negotiate individual placements.
iHeartMedia cites its iHeart Audience Network as the largest podcast sales network in the U.S., reaching about 50% of monthly podcast listeners. Its iHeartPodcasts division generates 177 million monthly downloads in the U.S. and ranks among the leading publishers across 19 measured podcast genres, according to the company.
The breadth of podcast programming allows advertisers to reach audiences based on interests, demographics and behaviors, including sports fans, business decision-makers, parents and culture enthusiasts.
The company recommends beginning the planning process
The company recommends beginning the planning process by defining the audience rather than selecting a familiar podcast. Advertisers should evaluate demographic and behavioral alignment, the context in which a message will be heard, the relationship between a host and audience, the appropriate ad format and the reach needed to support growth.
Host credibility and audience trust are particularly important considerations. iHeartMedia cited research indicating that 75% of podcast listeners say host influence matters most to them.
The company said host-read advertisements can be effective when trust, consideration and storytelling are campaign priorities. Such ads allow podcast creators to deliver brand messages in voices listeners already recognize.
Produced advertisements, meanwhile, offer consistency and can extend
Produced advertisements, meanwhile, offer consistency and can extend a message across a broader range of podcast audiences.
iHeartMedia said combining the two formats can help advertisers build personal connections while extending reach and reinforcing a consistent message.
The article also emphasizes the importance of establishing campaign objectives and measurement plans before advertisements begin running.
Podcast campaigns can be evaluated through measures beyond
Podcast campaigns can be evaluated through measures beyond impressions, including brand awareness, consideration, website visits, attribution, conversions and sales lift.
The company cited research showing that 67% of consumers report exploring brands they hear about on podcasts.
Effective targeting, according to iHeartMedia, requires advertisers to identify the audiences most important to their businesses, develop simple and relevant messages, select content environments that fit those messages and determine how campaign performance will be measured.
The company said podcast advertising can support both
The company said podcast advertising can support both local and national campaigns, provided the media plan reflects the advertiser’s objectives, audience and required reach.
iHeartMedia says combining audience strategy, scale, relevant content, creative execution and measurement can help advertisers turn podcast listening into meaningful brand connections.
