The first serious question about a new advertising channel is not whether it can generate clicks. It is whether marketers can connect those clicks to qualified actions and revenue. Branch says its ChatGPT Ads integration now attributes activity across app installs, mobile web, desktop and offline events through OpenAI's Conversions API.

The workflow uses a Branch Ad Link as the campaign destination, captures the OpenAI click identifier and forwards advertiser-selected conversion events. Branch also combines paid ChatGPT activity with organic AI discovery, while work on cost API integration is intended to bring return on ad spend into the same view.

What marketers should verify

An attribution platform can connect events, but it cannot prove incrementality by itself. Teams still need consistent conversion definitions, deduplication between browser and server events, consent controls and revenue reconciliation. A click attributed to ChatGPT Ads should be followed through to qualified lead, appointment, purchase and retained customer where possible.

Karim's strategic takeaway

Treat ChatGPT Ads as a measurable customer journey, not a novelty placement. Start with one high-intent service, send visitors to the most relevant page, and compare paid AI traffic with organic AI referrals and existing search campaigns. For healthcare campaigns, combine the measurement plan with the trust and compliance principles in my Healthcare Marketing approach.
