ChatGPT Ads for app installs: the honest state, October 2026
No install objective yet, but seven MMPs now attribute ChatGPT Ads installs. What works for an app today: web to app, or store links tracked by your MMP.
the short version: ChatGPT Ads still has no app install objective. what changed in late September is measurement: installs can now be attributed through seven mobile measurement partners, and campaigns can target the ChatGPT iOS and Android apps separately. so a store campaign is now measurable. the strongest setup for most apps is still web to app, and this page explains why, and how to run either one.
What you can and cannot do today
there is no “app installs” objective. campaigns pick one of three objectives: Views (billed per thousand impressions), Clicks (billed per click) or Conversions. none of them is an install campaign in the sense Meta or TikTok mean it.
installs are measurable through your MMP. OpenAI now lists Adjust, Airbridge, AppsFlyer, Branch, Kochava, Singular and Tenjin as supported mobile measurement partners. you put the partner’s attribution link in the ad, the partner attributes the install and sends it back, and it shows up in the Conversions column in Ads Manager within 24 to 48 hours. attribution through these partners is click based, so do not expect view-through installs.
you can target where the user is. platform targeting now splits into Android app, Android web, desktop web, iOS app and iOS web. those mean where the ad is shown, inside the ChatGPT app or in a browser, not where your app gets installed. it is still useful: someone using the ChatGPT iPhone app is one tap from the App Store, so an iOS app campaign pointing at your App Store listing is a sensible pairing.
whether delivery can optimise toward the install is the open question. the Conversions objective optimises toward one standard conversion event per campaign, and custom events cannot be used for it. so it comes down to whether the install your MMP sends arrives as a standard event you can select in your account. check that before you plan around it. if it is not selectable, run the store route as a click campaign and judge it in your MMP.
What to run first: web to app
this is not a workaround. it is how most large subscription apps acquire users anyway.
you send ChatGPT Ads traffic to a web page rather than a store listing. the page does the qualifying and often the selling, and the user lands in the app already converted. three things make it the better default:
the conversion objective works fully on the web. the OpenAI pixel and Conversions API report a sign-up or purchase directly, so delivery optimises toward the thing that makes you money rather than toward a click.
the page can answer the question the person just asked. a store listing has to serve everyone. a landing page can speak to the exact problem someone was talking to ChatGPT about, which is the whole advantage of this channel.
subscription economics. taking payment on the web rather than in-app changes what you keep, which for a subscription business is not a small detail.
the mechanics of building one are in the web to app playbook, including when it is the wrong choice.
If you send traffic to the store
this is now a real option rather than a blind traffic buy, as long as your MMP is wired in.
set up the partner first. you need a Pixel ID from a web data source and a Conversions API key, both from the Conversions section of Ads Manager, entered in your measurement partner. then map the install and the in-app events you care about, and use the partner’s attribution link as the ad’s destination, with the partner’s dynamic parameters in the tracking parameters field.
target the ChatGPT iOS app or Android app. match the platform to the store you are linking to, so nobody on a desktop browser is sent to an App Store page they cannot use.
your store listing is now your landing page. it is doing work it was not designed for, and the first two screenshots carry almost all of it. match the first screenshot to the ad: someone who clicked an ad about one particular problem and lands on a generic listing has just been given a reason to hesitate. the app store conversion calculator splits your funnel into the two steps that matter and shows which one is leaking, and the app store optimization playbook covers the fixes.
expect the numbers to disagree. your MMP and Ads Manager use their own attribution windows and settings. a gap between them does not mean either is broken. decide up front which one you budget from, and the right answer is usually your MMP.
Work out what you can pay before you spend
the break-even CAC calculator gives you the most you can pay per user. for a subscription app, the free trial to paid calculator shows the multiplier most founders miss: at 20% trial conversion, a ₹300 trial actually costs you ₹1,500 per paying customer.
the tracking side, including the pixel, the Conversions API and deduplication between them, is in ChatGPT Ads conversion tracking.
FAQ
Can you run app install campaigns on ChatGPT Ads?
not as a dedicated objective. campaigns are Views, Clicks or Conversions. you can send traffic to an App Store or Google Play listing and measure installs through a supported mobile measurement partner, or send it to a web page and convert there. most subscription apps do better with the web route.
Which MMPs work with ChatGPT Ads?
OpenAI lists Adjust, Airbridge, AppsFlyer, Branch, Kochava, Singular and Tenjin as supported mobile measurement partners. each needs your ChatGPT Ads Pixel ID and Conversions API key, and attribution through them is click based. attributed events appear as Conversions in Ads Manager after 24 to 48 hours.
What does “iOS app” mean in ChatGPT Ads platform targeting?
it means ads shown inside the ChatGPT iPhone app, as opposed to ChatGPT in a browser on an iPhone. it does not mean an install campaign for your app. it pairs well with an App Store link, because the user is already on an iPhone and one tap from the store.
Is web to app better than sending ChatGPT Ads traffic to the App Store?
for most subscription apps, yes. the web route lets the conversion objective optimise toward a sign-up or purchase, lets the landing page answer the exact question the person asked ChatGPT, and can improve what you keep on subscriptions. the store route is simpler and is now measurable through an MMP.
The honest summary
ChatGPT Ads is a real channel for apps now. the store route became measurable in late September, which it was not when this page was first written. the web route is still the better default, because that is where the conversion objective works end to end. wire your tracking before you spend, and check in your own account which conversion events you can actually select, because this platform changes month to month.
the rest of the app growth system is in the full playbook library, including paid ads, UGC and app store optimization.
