Digital Audio Deserves Strategic Role in Media Mix
The article argues that digital audio is an underestimated but fully mature channel in the digital media mix. Technologically, audio supports ad servers, CPM pricing, IO and programmatic buying, and standard planning and optimization mechanisms (frequency capping, data-driven targeting, standardized reporting). Creative production has become faster and more testable via AI tools that generate spot variants for A/B tests. Targeting is described as resilient in a post-cookie world, relying on login data, publisher signals, market studies and adserver data plus contextual signals (genre, time of day, weather, geo, device). Audio-specific KPIs (e.g., listen-through rate, unique listeners) and HTML-based attribution pixels enable conversion measurement. Curated content, server-side delivery and publisher whitelisting support brand safety. Statista forecasts global audio ad spend reaching about $42.8B by 2029. The piece recommends treating audio as a strategic, measurable channel rather than an experimental add-on.

Amplify Your Strategy: Make Audio Advertising Essential
Audio is underrepresented in advertising relative to time spent consuming it, a gap the author calls the 'sound gap.' The piece notes Americans spend about 3 hours 50 minutes daily on audio, with roughly 64% of that time in ad-supported content, yet audio accounts for about 4.5% of US media ad spend. Advances in first-party data, privacy-safe attribution models and AI-driven creative are helping connect audio exposure to brand lift, shopping activity and even offline outcomes. The article argues audio should be a core pillar of omnichannel strategy, not a niche add-on, supported by demand-side platforms and partnerships with streaming services. Amazon Ads has partnered with Spotify, SiriusXM Media and iHeartMedia to reach audiences at scale and to measure impact. The piece closes with a call to invest in reach, measurement and cross-platform collaboration to turn listening moments into measurable customer connections.

Digital Audio Must-Have for Retail Media Plans
The article argues digital audio should be a core component of 2026 retail media strategies, citing steady audience growth, expanding inventory and improving measurement. eMarketer forecasts nearly 240 million U.S. digital audio listeners in 2026 and projects audio ad revenue of about $7–$8 billion. Podcast listening surpassed AM/FM talk radio in late 2025, and platforms including Spotify, Amazon Music, Wondery, iHeart, SiriusXM and YouTube provide programmatic and first-party audio inventory. Retail and in-store audio (e.g., Walmart’s in-store radio) broaden reach near point-of-purchase. Demand-side platforms now offer native streaming-audio buys and tools like clean rooms and Amazon Marketing Cloud enable downstream measurement and MMM/incrementality testing. The piece recommends planning audio’s funnel role, testing structured pilots, investing in audio-specific creative, and integrating audio into media-mix measurement and budgets.
AI Search Fragments Digital Experience, Says Contentsquare
MarTech published an interview (March 25, 2026) with Jean-Christophe Pitié, chief marketing and partnerships officer at Contentsquare, discussing the firm’s large-scale digital experience data. Contentsquare’s signals indicate that the transition from traditional search to AI-powered/LLM-driven search has reduced organic traffic, fragmented discovery pathways, changed visitor behavior (LLM visitors differ from search visitors) and lowered time spent on websites. The conversation frames these trends as material for marketers, affecting acquisition, retention and site UX strategy. The piece is published by MarTech (owned by Semrush) and authored by Mike Pastore of Third Door Media.
