Criteo Expands Ads Inside ChatGPT
Criteo is scaling its advertising integration with OpenAI’s ChatGPT, reporting over 2,000 brands buying ChatGPT inventory via Criteo (up from ~1,000 in May). The offering, bookable through Criteo’s self‑service platform, is available in the US, Australia, Canada, New Zealand, the UK, Japan and South Korea; continental Europe has no start date yet. Criteo introduced “Prompt Smart Ads,” which combine catalog and commerce signals with the user’s query to tailor ads and product descriptions; early tests show increased budget delivery and roughly fourfold higher spend after activation. The company reports ChatGPT ad traffic with 2–3x higher click‑through rates and conversion rates that beat other referral channels, with over 80% of ad-driven ChatGPT traffic coming from new customers. Criteo also highlighted a Retail Media use case with Albertsons that embeds sponsored products into a conversational, AI-driven shopping experience.

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.
