Radio and podcast host reads — can deliver stronger brand impact than other paid creative when advertisers name themselves immediately and lean into entertaining, emotion-driven messages, according to a new global study.
The findings are in “The Creator Effectiveness Playbook: How to Build Your Brand with Creators,” from WPP Media, creative-testing firm System1, and TikTok. Cumulus Media/Westwood One Audio Active Group Chief Insights Officer Pierre Bouvard examines the research in a new blog post.
Researchers measured responses to 1,217 paid ads among 182,500 TikTok users in eight markets and linked those results to in-market brand-lift data. The campaigns represented $71 million in media spending and 23.6 billion impressions.
Creator ads — which Bouvard likens to radio and podcast host reads — produced greater brand-memory lift, combining awareness and ad recall. Two factors stood out: naming the advertiser within the first two seconds, and generating strong positive emotion through entertaining content.
For video podcasts and other audio with video, System1 recommends both saying and showing the brand in those opening two seconds. That “say it and show it” approach produced seven times greater brand recognition than ads with no brand cues at the start.
Humor amplified the effect. In System1 testing, the funniest ads scored an average 3.4-star emotional response versus 2.2 stars for the most serious ads, and they generated five times the long-term market-share growth of the least funny creative.
Dull advertising carried a measurable cost. Analysis of the IPA Effectiveness Databank found advertisers may need two to 2.6 times more media spending for dull ads to match the business results of more interesting creative. Interesting ads produced 6.1 times more share growth than dull, rational ones.
Audience size was not the deciding factor. WPP Media and System1 looked at creators from micro-influencers with 10,000 to 100,000 followers to celebrities with more than a million. Across all four audience-size groups, the most entertaining ads built strong brand memory.
Bouvard says the results also apply to AM/FM talent endorsements. Jacobs Media’s Techsurvey has found DJs and hosts are among the main reasons people listen to radio, and a MARU/Matchbox study found listeners form long-term bonds with personalities who make them laugh, think, and feel tied to their communities.
His takeaway for audio advertisers: pair “salesmanship and showmanship” — identify the brand early and often, and give personalities room to make the message entertaining, memorable, and emotionally engaging.
