Short answer
ChatGPT ads can target five platforms: Android app, Android web, desktop web, iOS app and iOS web. Platform targeting is optional and set per campaign, and reports can be segmented by the same five platforms.
When to split platforms
- B2B: put desktop web in its own campaign; work research happens at desks and forms convert better there
- Apps: target the app platforms that match your store listing
- Mobile landing pages: only include mobile if your page works well on a phone
How to read the results
Use the Segment menu to split results by platform, country and device, then move budget to the platforms that bring the outcomes you want, not just clicks.
