ChatGPT Ads is here, and almost no measurement stack can see it yet. OpenAI has opened paid placements inside a product that 900 million people open every month. The brands moving first are taking placements their competitors will not notice for another year. The problem is that a click inside ChatGPT does not show up in your existing MMP reports on its own, and an install you cannot attribute is an install you cannot optimize.
This post walks through how ChatGPT Ads attribution actually works for mobile apps, how to wire up a tracking link and conversion measurement, and which metrics tell you whether the channel is working. For the channel basics, see how ChatGPT Ads work and ChatGPT Ads pricing explained.
If you want the channel run for you end to end, agencies like Focal handle creative and campaign management. This guide is about the other half of the job: measuring it.
What ChatGPT Ads Are and Why Mobile Apps Should Care
ChatGPT Ads are paid placements served inside ChatGPT conversations, shown to users while they research products, tools, and services in a chat interface rather than scrolling a feed. That difference in context is the whole point. A user asking ChatGPT to compare budgeting apps or recommend a language tutor is much closer to a decision than someone half-watching a video ad. The intent looks more like search than social.
For a mobile app, that means ChatGPT Ads can drive installs from genuinely high-intent users, often at a lower cost than Google on the same research queries, before the channel saturates and prices rise. One thing to know up front: OpenAI shows these ads to logged-in free-tier users who are 18 or older, not to Plus, Pro, or Business subscribers, so the audience skews toward adults in active research mode. The value only shows up if you can prove which installs came from ChatGPT and what those users did after they opened your app.
How ChatGPT Ads Attribution Works
The mechanic mirrors how any modern MMP attributes a paid install, adapted to the new channel:
-
A user clicks your ChatGPT Ad. Your ad's landing page is a Linkrunner tracking link, so the click is captured and the tracking parameters OpenAI passes persist on it. The link routes the user to the App Store or Play Store.
-
The user installs and opens your app. On first launch, the Linkrunner SDK reads the install referrer and matches the new device back to the exact ChatGPT Ads campaign that drove the click.
-
The install is credited and deduplicated. Linkrunner checks the claim against Meta, Google, TikTok, and your other channels so the right source gets credit instead of every platform claiming the same user.
-
Post-install events flow in. Activations, purchases, and revenue attach to that ChatGPT-attributed user, so you measure cost per paying user, not just cost per install.
This is the same install-referrer and post-install event model that already works for Google and Meta ads, which means ChatGPT Ads slots into reporting your team already understands.
Step by Step: Set Up ChatGPT Ads Attribution in Linkrunner
If you already run the Linkrunner SDK, adding ChatGPT Ads takes an afternoon, not a sprint.
-
Install or confirm the SDK. Make sure the Linkrunner SDK is live in your iOS, Android, React Native, Flutter, or Expo app and capturing installs.
-
Create a tracking link. Generate a Linkrunner tracking link for the campaign and use it as your ad's landing page. Tracking parameters persist on the click, so the install maps back to the correct campaign and creative.
-
Turn on conversion measurement. Choose which events, install, activation, purchase, and revenue, you want tied back to the ChatGPT Ads campaign, and over what window.
-
Verify with a test click. Run a test click through a real ChatGPT Ad, install on a test device, and confirm the install lands attributed to the right campaign in your dashboard.
What Metrics to Watch
Treat ChatGPT Ads like any new channel under evaluation, and compare it honestly against the channels you already trust:
-
Cost per install (CPI) by channel. Put ChatGPT Ads next to Meta, Google, and TikTok. Early ChatGPT CPI often looks favorable because competition is thin, but read it alongside quality, not in isolation.
-
Post-install events. Activation rate, first purchase, and day-7 retention tell you whether ChatGPT installs stick. A cheap install that never activates is not a win.
-
ROAS within a consistent window. Always compare return on ad spend over the same attribution window across channels, or the comparison is meaningless.
-
Blended effect. Watch whether adding ChatGPT Ads lifts total installs or just shifts credit around. Linkrunner's deduplication keeps that honest.
Set Up Conversion Measurement for ChatGPT Ads
Cost per click tells you what traffic costs, not what a customer costs. Conversion measurement closes that gap. When Linkrunner ties installs, activations, purchases, and revenue back to the ChatGPT Ads campaign that drove them, you can see true cost per paying user and ROAS for the channel, then move budget toward the creatives and campaigns that actually convert.
That is the same discipline that makes Meta and Google spend efficient, applied to ChatGPT Ads before most of your competitors even have measurement in place. For the full measurement walkthrough, including why UTM parameters alone fall short for apps, see how to measure and attribute ChatGPT Ads.
Frequently Asked Questions
What is ChatGPT Ads attribution?
ChatGPT Ads attribution credits your mobile app installs and in-app events to the ChatGPT Ads campaign that drove them, deduplicated against your other channels so the right source gets credit.
How does Linkrunner attribute a ChatGPT Ads install?
Your ad's landing page is a Linkrunner tracking link. It captures the click, routes the user to the store, and the SDK matches the install on first open, then ties post-install events back to the campaign through conversion measurement.
Does this work on both iOS and Android?
Yes. Linkrunner attributes ChatGPT Ads installs on both platforms, including SKAN 4.0 conversion-value mapping for privacy-safe iOS measurement after ATT.
How fast can I go live?
If the SDK is already in your app, ChatGPT Ads attribution turns on as soon as you point a campaign at a Linkrunner tracking link, usually the same afternoon.
