ChatGPT Ads Adds Conversion Bidding and Measurement

ChatGPT Ads rolled out new performance-focused features including conversion-optimized cost-per-click (oCPC) campaigns, mobile measurement integrations with AppsFlyer and Adjust, and improved budget and campaign management tools. Budgets will be managed using a rolling seven-day average with automatic pacing, and advertisers gain Automatic Advanced Matching using hashed customer data for better website conversion attribution. The Ads API now supports asynchronous bulk creation and updates for campaigns, ad groups, and ads, and geographic exclusions and updated product cards (with pricing and star ratings) are being added. The release emphasizes foundational capabilities—conversion optimization, attribution, and scalable campaign operations—making ChatGPT Ads more competitive with established self-serve platforms like Google Ads and Meta Ads.

OpenAI Partners with LiveRamp to Measure ChatGPT Ad Conversions

OpenAI has partnered with data-matching firm LiveRamp to allow selected advertisers to send conversion (transaction) data into OpenAI’s conversion API for ChatGPT ads. The U.S.-only integration (with Europe to follow) will initially be available to mutual clients of OpenAI and LiveRamp and focuses on transaction data (product, price, date) rather than clicks; LiveRamp hashes emails (with RampID support planned) and forwards matched data to OpenAI while attribution methodology remains OpenAI’s responsibility. LiveRamp expects its first advertiser to go live the week of publication. The tie-up comes as OpenAI rapidly builds measurement and accountability into its nascent ads business and is positioned as a step toward performance attribution parity with established self-serve ad platforms. The deal’s timing and LiveRamp’s pending Publicis acquisition raise questions about vendor neutrality as the partnership scales.
