AI Advertising Market: 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.
ChatGPT Ads represent a new, potentially significant advertising channel from a major AI platform; early rollouts and feedback shape advertiser adoption and industry dynamics.
