ChatGPT Ads Set New Rules for Campaign Planning via JOM
OpenAI expanded ChatGPT Ads to 31 European markets in late August, followed by self-service access via Ads Manager. The media agency JOM analyzes the channel and recommends campaigns built around specific research, comparison, and decision contexts. Key planning element: 'Context Hints' – semantic descriptors of product benefits, target users, and relevant situations, which do not require exact keyword match. JOM advises structuring tests with 5-10 distinct decision contexts per test, with matching creatives and landing pages. Relevance-weighted second-price auction considers context, hints, ad, landing page, and bid. Available campaign types: CPM, CPC, and oCPC with pixel or CAPI tracking. Reporting is aggregated, excluding prompts and chat logs. Meanwhile, Criteo offers ChatGPT Ads in Germany and 30 other European markets, reporting 2,000+ brands using its platform, with higher click and conversion rates.
Major platform (OpenAI) expansion of advertising to European markets, creating a new channel and impacting campaign planning. It signals the rise of conversational ads in the AdTech ecosystem.

ChatGPT Tests Conversational Advertising Model
OpenAI is expanding advertising across ChatGPT, rolling out a beta self-serve Ads Manager and adding features such as cost-per-click bidding, conversion tracking and location targeting. The system matches ads to the context and intent of user conversations and accepts advertiser 'context hints' rather than keyword lists. Early pilots involved major advertisers, and OpenAI reported roughly $100 million ARR by March and optimistic long-term ad revenue forecasts. Advertisers and analysts say tooling, reporting granularity and campaign controls remain more limited than Google and Meta, and privacy protections mean advertisers do not receive underlying conversations or user personal data.
German Marketers Share Mixed First Experiences with ChatGPT Ads
OpenAI's ChatGPT Ads launched in Germany in late August, allowing advertisers to book via agency partners or a self-serve tool. Early feedback from German marketers is mixed. Dentsu's Markus Caspari sees potential but notes high CPMs and limited reporting. Performance marketer Carlo Siebert reports poor results, with few clicks and conversions, and tracking discrepancies. OpenAI's VP Ads, Dave Dugan, acknowledges the beta stage and promises improvements. Criteo reports CTRs 2-3x higher and 80% new customers, especially effective for consultation-heavy categories. OpenAI is also testing 'Sponsored Agents' and partnering with Best Buy for in-Chat commerce.
Criteo Enables Direct Booking of ChatGPT Ads in Europe
Since August 24, 2026, ChatGPT Ads are available in Germany and 30 other European markets. Criteo has enabled advertisers to book ChatGPT Ads directly via its Cross‑Channel Commerce platform in the DACH region and 28 additional European markets, allowing brands to run ads without routing buys through agency partners. Criteo says more than 2,000 retailers and brands already advertise on ChatGPT via its platform and that over 80% of ad‑driven traffic comes from new customers. OpenAI has announced agency booking options and highlighted the role of ChatGPT Ads in moments of product discovery, while Google has launched related AI ad formats such as Conversational Discovery Ads for its AI Mode.
