Instagram ads for app installs
The choice of objective decides whether your store link is opened by the operating system or by a browser that cannot open it.
6 August 2026 by PAD team
Two paths to the store
| Objective | How the store opens | Store link works |
|---|---|---|
| App promotion | native store sheet | yes |
| Traffic | in-app browser | no |
| Engagement | in-app browser | no |
| Conversions | in-app browser | no |
This single distinction explains most unexplained differences in install rates between campaigns for the same app.
Why anyone uses the other objectives
App promotion optimises for installs and needs the SDK or SKAdNetwork setup to do it well. Traffic campaigns are cheaper per click, work without app-side integration, and let you put a landing page or quiz in front of the download, which many products need.
Meta also rejects raw store URLs as traffic destinations, so those campaigns necessarily point at a web page, and the store link ends up at the bottom of it.
Making traffic campaigns work
- The final Download button escapes the in-app browser instead of linking directly to the store
- Campaign parameters attach at that last hop, not to the ad's destination URL
- Measure how many taps escaped, not just how many buttons were pressed
- Compare against an install campaign for the same app as a sanity check
Creative implications
If a share of taps will need a manual button, the copy on that button matters. "Open in browser to continue" converts better than a spinner, and about half the people who see it act on it in our traffic.
What to watch in reporting
Click to install ratio, split by objective. If app promotion looks healthy and traffic looks broken for the same creative and audience, the difference is the browser rather than the ad.
One link at the end of the funnel that gets the tap out of the browser, with delivery stats per campaign.
