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.

AI agents threaten advertising as we know it
AI agents like Meta's Muse, OpenAI's ChatGPT, and Google's Gemini are disrupting traditional advertising by not clicking banners or sponsored results, threatening the core revenue of platforms like Meta and Amazon. New monetization models include subscriptions, transaction fees, and pay-for-results. Protocols such as Google's Universal Commerce Protocol, OpenAI/Stripe's Agentic Commerce Protocol, Visa's Trusted Agent Protocol, and Ad Context Protocol standardize agent-commerce interactions, creating new ad slots within agent workflows. Early signals include Amazon blocking Muse and declining Google traffic to news sites. Despite the threat, ad giants report growth, including ChatGPT ads reaching $1 billion annualized revenue, proving ads work in AI assistants, especially at the top of the funnel. Adoption remains early, with only 5% of US consumers using agents for fully autonomous purchases.
OpenAI Tests Ads Linking to AI Agents
OpenAI is testing a new ad format in a beta ChatGPT Ads Manager that opens business-specific ChatGPT conversations instead of sending users to landing pages. The reported workflow includes automated site crawling to build business profiles and configurable Business Agents created with custom instructions, product feeds, Model Context Protocol tools, and lead forms. Clicks are routed into agent-powered chats that can answer questions, surface and recommend products, capture leads, and potentially handle orders or bookings within the interface. The capability appears available to a limited group of advertisers in the test. The feature was publicly spotted by Juozas Kaziukėnas and reported by MarTech on 2026-08-04; other outlets (Search Engine Land, MEEDIA) have noted similar platform-driven conversational commerce trends, including Google tests of AI-generated product descriptions.
AI Agents Transform Shopping from Circulars to Automated Purchasing
This article explores how AI is reshaping the shopping journey, moving beyond traditional advertising to a future where AI agents act on behalf of consumers. It highlights that 73% of parents plan to use AI in back-to-school shopping, citing a PwC study. The evolution from static ads to predictive, adaptive creative is discussed, with comments from Priti Ohri of Advertible on dynamic creative. The piece also covers conversational AI, referencing Criteo's Prompt Smart Ads, and the transition from assistance to delegation, noting that only 11% of consumers are ready for AI to make purchase decisions. Becky Gundy of CHEQ predicts agents will soon handle purchases end-to-end, emphasizing that advertisers must appeal not only to consumers but also to their AI agents.
