Conversational Ads Market: Ads Enter AI Assistants: What Marketers Need
Generative AI is reshaping digital marketing, moving beyond content creation into conversational, agent-driven advertising that can use product catalogues, recommendations and agent-to-agent transactions. Platforms such as Google Ads and OpenAI’s ChatGPT offer AI-driven ad formats and buying options (CPM and CPC), while Amazon’s Alexa for Shopping (Rufus) demonstrates product-feed-driven shopping assistance. Startups like Gravity are reportedly working with retailers (Target, Best Buy) on agent-to-agent advertising. The shift raises practical challenges for marketers around attribution, CPC measurement, product-feed quality, brand safety, and auditability of AI agent decisions. Research (a May 2026 study and a 2026 paper titled “Auditable Agents”) highlights risks from unsupported AI claims and outlines requirements for auditability. The article argues organisations need AI governance, improved product data, and new measurement approaches to participate effectively in AI-led buying journeys.
AI assistants entering advertising change ad formats, measurement, attribution, product-feed requirements and governance — impacting strategy, measurement and tech across the AdTech ecosystem.
