The Audio Advantage: Memorable, Efficient, Measurable

Earlier this year, leaders from the audio industry joined the IAB Annual Leadership Meeting to highlight how audio is an efficient, memorable and measurable platform to add to a brand’s media mix.

At its core, audio hits the brain differently than visual data, capturing attention that results in higher memorability. What does that mean for your brand? 86% of podcast listeners can recall a specific ad they heard in the last week — the highest recall rate across 22 ad-supported platforms¹ — making audio a must-have in any media campaign.

The Audio Advantage

Audio drives performance for brands.

ROI: Reality vs. Perception

Marketers perceive audio as being less effective than other mediums, but the opposite is true. Radio has the fourth highest average ROI globally compared to other media types, outperforming TV, CTV and video. Podcasting even outperforms traditional television at driving brand outcomes.²

Analysis using Nielsen’s Marketing Mix Modeling (MMM) tool found shifting just 10% of a media budget to audio can increase a campaign’s total reach by over 20%.³

Measurement & Incrementality

According to Podscribe benchmark data, podcast ads result in a 28% conversion incrementality — meaning 28 out of 100 conversions are purely driven by the audio impression.⁴

As podcast audiences are typically harder to find in other channels, advertisers are rewarded by entering the audio space the right way and using the strengths of that medium to drive performance.

Authentic & Trustworthy

Audio sponsorship is rated among the most authentic, with radio and podcasting ranking #1 and #3 respectively in Sounds Profitable’s The Advertising Landscape research study.¹

Where a brand shares its message plays a role in transferring trust by association. Research from Neuro-Insight and NPM shows associating with a trusted media brand helps build trust and can lead to purchase intent and increased brand value.

How are brands using audio in their media mix?

Brands use audio to drive full-funnel results that extend beyond traditional clicks. Success in audio advertising is measured through other key performance benchmarks including brand awareness, consideration, favorability and purchase intent.

Heard and remembered: how NPR audio made Kroger's message stick

Research conducted with Neuro-Insight, which features grocer brand Kroger, reveals that NPR sponsorship audio drives both trust and memorability for brands. Kroger’s NPR audio message saw the highest “detail memory encoding” during key branding moments, meaning the most essential details were what were remembered by listeners.
