iHeartMedia Inc. and Omnicom Media Reveal Groundbreaking Insights into Audio Advertising

According to the study, audio now constitutes approximately one-third of daily media consumption, reinforcing its integral role in marketing strategies. With more than 3,500 U.S. adults participating in the research, the study employed a controlled experimental design to evaluate the effectiveness of different audio ad formats, including standard ads, host-read messages, long-form content, and dynamic and interactive formats. These insights provide advertisers with a robust framework for aligning audio strategies with specific business goals.

Lainie Fertick, President of iHeartMedia Insights, emphasized the unique duality of audio advertising, stating, “Audio is one of the few channels that delivers both scale and intimacy.” The findings indicate that when brands leverage trusted human voices alongside innovative formats, audio can become a potent catalyst for building trust, fostering engagement, and accelerating purchase behavior.

The study revealed remarkable metrics showcasing the effectiveness of audio advertising across various stages of the consumer journey:

Furthermore, audio advertising demonstrated a “multiplier effect,” enhancing responsiveness across social and digital channels, thereby increasing engagement and branded search activity for brands utilizing audio in their marketing strategies.

The research highlighted the significance of host-read ads in fostering emotional connections and building brand trust. Messages delivered by familiar voices yielded stronger gains in brand relevance and consumer intent compared to standard ads. Notably, exposure to host-read advertisements resulted in a remarkable 20-point lift in likelihood to purchase within a week, significantly surpassing the impact of traditional ads.

Long-form host-read executions further magnified these effects, demonstrating up to 2X higher recall than shorter ads. This format allows brands to engage in deeper storytelling, making it particularly effective for consideration and conversion objectives.

Kara Manatt, Executive Vice President of Intelligence Solutions at Omnicom Media, remarked, “Listeners develop real relationships with the voices they hear every day. When brands tap into that credibility at scale, the impact is measurable—trusted voices don’t just influence perception, they drive action.”

The study also explored the potential of emerging audio formats in enhancing brand relevance and consumer engagement. Dynamic ads, tailored to the context of the listener—such as time of day or environmental factors—showed improved perceived relevance (80% vs. 73% for standard ads) and delivered stronger results in search intent.

Interactive motion-activated units, designed to prompt listener engagement, proved particularly effective among younger and in-market audiences. By transforming passive listening into active participation, these innovative formats help brands convert high-intent consumers more efficiently.

The research underscores the importance of strategically sequencing audio formats, combining trusted host-read ads with dynamic and interactive elements to guide consumers seamlessly from awareness to action within a cohesive audio strategy.

The findings from iHeartMedia and Omnicom Media underscore the vast potential of audio advertising in today’s media landscape. As brands increasingly recognize the value of audio as a powerful tool for driving brand outcomes, the insights from this study will undoubtedly shape future advertising strategies.

As the audio landscape continues to evolve, iHeartMedia remains at the forefront, leveraging its extensive reach and innovative capabilities to redefine the role of audio in marketing. With a strong commitment to enhancing consumer engagement and delivering measurable results, iHeartMedia is poised to lead the charge in the next wave of audio advertising innovation.
