Podcast Ads Show 4.9x ROI as Asia Inventory Expands
Podcast ads in Asia deliver, with BBC, iHeart, and Dentsu expanding inventory. CMOs can’t ignore the rising conversion power.
Podcast advertising in Asia is delivering 4.9 times return on investment and 4.2 times return on ad spend, according to recent industry benchmarks, as major media companies expand premium inventory across the region's fastest-growing markets.
Premium Inventory Opens Across Asia
BBC Studios has partnered with Audacia to offer premium podcast ad inventory across seven Asian markets, including Indonesia, Vietnam, and Malaysia. The collaboration gives advertisers access to BBC's podcast catalog in markets where weekly listenership reaches significantly into Indonesia, Thailand, and India.
iHeartMedia announced a partnership with Mammoth Media Asia to launch multilingual podcasts targeting music, wellness, and sports audiences. The expansion comes as Dentsu India launched a dedicated podcast network to meet rising advertiser demand for branded audio content.
The moves follow Acast's "Podcast Pulse 2025" study, which found that 67% of global podcast listeners have made purchases based on podcast recommendations. The research, surveying over 2,500 listeners across nine countries, revealed that 84% of listeners said podcast hosts changed their perspectives on topics.
Engagement Rates Surpass Social Platforms
Asian podcast audiences show staggering engagement rates near 85%, surpassing social media in some markets. The performance metrics come as the Asia Pacific podcast market grows at 30.2% compound annual growth rate, projected to reach US$3.1 billion by 2031 from US$373.6 million in 2024.
China's podcast advertising revenue hit RMB 3.3 billion (~US$450 million) in 2024, with Ximalaya users showing high purchase intent. Nearly 50% of users purchased paid podcast programs on the platform. Luxury brands Gucci and Giada achieved high brand recall through branded podcasts, with Giada's "Herstory" podcast reaching over 1 million subscribers on Xiaoyuzhou without celebrity endorsements.
Podcast advertising is forecast to grow at 15.5% annual rate across Asia Pacific through 2030, led by India's regional-language content expansion. Dynamic ad insertion tech enables real-time personalized advertisements, particularly in India's growing market.

BetterHelp and HelloFresh saw 60% and 50% sign-up increases, respectively, through podcast ads in Southeast Asia, where 20% of e-commerce sales are driven by creator and podcast content.
Indonesia Emerges as Audio Hub
Radiodays Asia 2025 in Jakarta highlights Indonesia's emergence as an audio innovation hub. This comes as Indonesia leads regional weekly listenership at 59%, followed by Thailand and India at 54% each.
