As the digital advertising landscape continues to evolve, the Interactive Advertising Bureau’s (IAB) “2025 Outlook: A Snapshot into Ad Spend, Opportunities, and Strategies for Growth” provides critical insights into what’s ahead for audio advertising and podcasts. Here’s what you need to know about the trends and projections shaping the industry.

The podcast ad market remains robust, with the IAB’s slower growth forecast reflecting a maturing industry where smaller percentage increases translate to larger dollar gains. Even CTV, the fastest-growing medium, won’t match last year’s growth rates.

While the IAB anticipates growth across all digital channels, traditional media is projected to see a 1.5% decline in ad revenue this year, impacted by the absence of major cyclical events like the election.

Steady Growth for Digital Audio and Podcast Advertising

Despite a maturing market, podcast advertising is expected to grow by 7.4% in 2025, outpacing the 4.8% increase projected for digital audio (excluding podcasts). While these rates are more modest compared to previous years, they reflect a sector that is solidifying its value.

With a projected 3.6% share of total media spending for podcasts and 3.3% for digital audio, advertisers recognize the potential of audio formats to engage audiences.

The Role of Creativity and Performance in Audio Advertising

Marketers are increasingly prioritizing performance advertising to demonstrate ROI, with six in ten buyers feeling the pressure to show returns on media spending. Audio advertising’s ability to create emotionally resonant and memorable experiences makes it a critical tool for both brand-building and performance marketing.

As David Cohen, CEO of IAB, notes, “Budgets are being focused where consumers, commerce, and video converge, driving meaningful business results.”

Challenges and Opportunities

While the audio ad market is growing, challenges remain. Buyers are grappling with issues like cross-channel media measurement (a concern for 44% of respondents) and managing reach and frequency (36%). However, advancements in leveraging first-party data and sell-side partnerships are easing some hurdles, enabling better targeting and personalization in campaigns.

Audio’s Competitive Edge in the Media Mix

Podcasts and digital audio offer unique opportunities to connect with audiences in a personal, immersive way. These formats are particularly effective at:

  • Building Brand Equity: Creative and consistent messaging strengthens brand recall and affinity.
  • Driving Consumer Engagement: Audio ads can deliver personalized and contextually relevant experiences.
  • Showcasing Performance: Real-time metrics and actionable insights support data-driven decision-making.

Podcast Advertising: Maturity Meets Momentum

The IAB’s outlook highlights podcasting’s journey from a high-growth channel to a more stable yet lucrative part of the media mix. As publishers continue to innovate with dynamic ad insertion and programmatic capabilities, the value of podcast advertising will remain strong, even as growth rates level out.

Looking Ahead: Key Takeaways for Advertisers

  • Invest in Creativity: Engaging, memorable audio ads drive performance and build lasting connections.
  • Embrace Technology: Utilize advancements in AI and first-party data for targeted, efficient campaigns.
  • Adapt to Trends: Monitor changes in consumer behavior and ad channel innovations to stay competitive.
