Branch Expands AI Measurement With ChatGPT Ads Attribution Across App, Web and Desktop

New support helps advertisers connect paid ChatGPT Ads campaigns with organic AI traffic and every other customer acquisition channel

MOUNTAIN VIEW, Calif., Sept. 24, 2026 /PRNewswire/ -- Branch, the linking and measurement partner for growth-focused brands, today announced support for ChatGPT Ads attribution across mobile apps, websites and desktop applications. As a measurement partner to ChatGPT Ads, advertisers can use Branch to measure customer activity generated by campaigns running in ChatGPT and connect that activity to installs, app opens, conversions and other downstream business outcomes.

As AI becomes a new channel for customers to discover brands and make purchasing decisions, marketers need to understand how paid campaigns and organic AI visibility contribute alongside search, social and the rest of their media mix. With Branch, advertisers can link mobile, web-to-app and web journeys to ChatGPT Ads campaigns, attribute down-funnel app and web activity, and pass selected conversion events back to OpenAI for optimization.

"AI discovery is becoming part of the broader customer journey, not a separate marketing category," said David Karnstedt, CEO at Branch. "Marketers should be able to see how paid ads, organic referrals, web visits, app activity and other marketing touchpoints connect to conversions. That is the measurement foundation Branch has built over the last decade."

Branch is designed to support measurement across the customer journey:

• Attribute app installs, reengagements and post-install events generated by ChatGPT Ads
• Measure web visits and conversion events originating from ChatGPT Ads campaigns
• Deep link users from ChatGPT into relevant app and web content, preserving context and creating more relevant customer journeys
• Share advertiser-selected events with OpenAI for campaign reporting and optimization
• Analyze ChatGPT Ads performance including cost and conversion data alongside other paid, owned and organic channels in Branch
• Measure paid ChatGPT Ads campaigns alongside organic traffic from ChatGPT and other AI platforms
• Understand how AI-driven touchpoints contribute across the customer journey

Branch's comprehensive channel coverage, cross-platform and cross-device architecture, and full-funnel measurement give marketers a foundation for testing ChatGPT Ads as a growth channel while connecting those experiments to real conversion and revenue outcomes. As AI reshapes how customers discover, evaluate and engage with brands, Branch gives marketers a unified way to measure performance across apps, websites, devices and emerging paid and organic channels.
