RMS Studies: Audio Advertising Boosts Brand Search and ROI
RMS, a German audio advertising marketer, released two studies demonstrating the effectiveness of audio advertising in the age of generative AI. The first study, 'Audio on – Search up!', conducted with bynd, analyzed 21 brands and found that audio advertising significantly increases brand-related Google search volume, with up to 70% of the effect persisting over weeks. The second study, 'Audio On, ROI Up', based on 166 marketing-mix models, showed that radio achieves a median ROI index of 175 compared to 100 for TV, and digital audio reaches 130. The studies emphasize that audio builds mental availability, which is crucial as AI-driven search makes brands more comparable. RMS argues that audio should be weighted more heavily in media plans given its proven contribution to brand building, demand generation, and economic success.
The article presents research findings from RMS that highlight the effectiveness of audio advertising, which is relevant to the AdTech industry as it informs media planning and budget allocation. The studies provide concrete ROI data that could influence advertiser strategies.

RMS Interview: Audio Ads Impact Before Click
In an interview with ADZINE, Frank Nolte, Director Publisher & Product at RMS, discusses the evolving audio advertising market. He emphasizes that audio builds brand preference and demand before the click, requiring more sophisticated measurement. Podcast advertising is becoming more scalable through technical integration and dynamic ad insertion, complementing host-reads. Programmatic is growing in digital audio but linear radio programmatic is still nascent, with potential for audience-based buying. AI is transforming audio creation and, with agentic buying, will impact planning and purchasing, making it crucial for media to be visible and understandable to AI systems.
Digital Audio Revolutionizes Performance Marketing Success
The article reviews multiple case studies showing digital audio (streaming audio, radio and podcasts) functioning as a measurable performance channel across the marketing funnel. Regional sales‑lift tests and brand‑lift studies demonstrate audio-driven uplifts: Rama's regional audio campaign produced short‑term and persistent sales gains; Meßmer’s Cold Tea launch in NRW yielded double‑digit sales increases and a post‑campaign halo; Persil’s podcast ads improved purchase probability and brand metrics among non‑users. Additional examples (Telekom, PayPal, Etsy) show audio can boost preference, mental reach and site visits. The piece argues that modern measurement infrastructures (sales‑lift and brand‑lift analyses) by audio sellers and research partners make acoustic ads' impact traceable and justify adding digital audio to performance media mixes.
Study: Audio's Mental Availability Boosts Brand Reach
The study "Audioeffekt 2026 – Always within Reach", produced by RMS and ARD MEDIA, examines how mental availability in everyday situations contributes to media reach and brand presence. Based on an online sample of 2,878 German adults, the research measured usage across eleven media types over five days and associations with 25 Media Entry Points. Results show radio leads the surveyed media with an 18% Mental Market Share and 86% of respondents associating radio with at least one relevant everyday situation. Music streaming and radio also score highest on Network Size (7.1 and 6.8 associations respectively). The study argues that audio—particularly radio and music streaming—is strongly embedded in recurring daily contexts and therefore important for brand building and media planning.
