AI Search Ads

AI search ads are paid placements shown inside or next to an AI-generated answer, labeled as sponsored and kept separate from the organic response. They are the paid counterpart to organic AI search visibility: a brand can earn a citation in the answer, buy a placement beside it, or both. By October 2026 three major platforms sell them, and one has stopped.

Google runs ads in two AI surfaces. Ads can show above or below AI Overviews in every market where the feature is available, and inside AI Overviews in English in 12 countries, including the US, Canada, Australia and India. Google matches these ads to both the query and the content of the overview, so it steers advertisers toward broad match, AI Max, Performance Max and Shopping campaigns, and it excludes sensitive verticals such as health, finance and politics (Google Ads Help). Google Ads does not report the in-Overview placement separately. In AI Mode, Google has tested ads in the US since 2025 and showed new formats at Google Marketing Live in May 2026: Conversational Discovery ads, Highlighted Answers that place sponsored businesses inside recommendation lists, and Direct Offers, a promotions pilot that began in January 2026. There is no AI Mode campaign type; ads come from eligible existing campaigns.

OpenAI started testing ads in ChatGPT in the US on February 9, 2026. Ads appear for adult users on the Free and Go plans; Plus, Pro, Business, Enterprise and Edu accounts are ad-free. OpenAI opened a self-serve Ads Manager in May 2026, said on August 31, 2026 that ChatGPT ads had reached a $1 billion annualized revenue run rate and were sold in more than 40 countries, and on October 5, 2026 announced a visual ad format for image generation, starting with US tests (OpenAI). OpenAI says ads do not influence ChatGPT's answers. Advertisers buy on CPM or CPC in a second-price auction, and OpenAI's OAI-AdsBot crawler checks submitted landing pages.

Microsoft serves Search, Product, Multimedia and some vertical ads inside Copilot answers, and has piloted interactive Showroom ads with select advertisers. Perplexity, one of the first AI search products to test sponsored answers in 2024, phased its ads out in late 2025 and told the Financial Times in February 2026 that it had no plans to bring them back. Anthropic has said Claude will stay ad-free.

For GEO teams the main effect is on commercial prompts. An ad that sits above or inside an answer competes for the same attention as your organic citation, and it shows which competitors value that question enough to pay for it. Our ChatGPT ads over time report found no ads in tracked ChatGPT search responses until May 27, 2026, then a jump past 30% of responses on July 1, after which the daily rate mostly stayed between the low 20s and high 30s. That kind of change can cut organic click-through on a prompt even when your citation share holds steady.

Treat ads as a separate layer in reporting. For the prompts you track, record whether an ad appeared, who the advertiser was, what the creative promised and where it linked, then read that next to your organic visibility. Promptwatch's Ads Radar does this for ChatGPT, AI Overviews and AI Mode, as described in our Ads Radar announcement.
