Example
Your Meta app install campaigns drove 2,847 installs in Q2 across iOS and Android.
| Campaign | Installs | Spend | Cost per Install |
|---|
| iOS Lookalike | 1,423 | $4,269 | $3.00 |
| Android Broad | 892 | $3,568 | $4.00 |
| Retargeting | 532 | $1,330 | $2.50 |
How It Works
Meta counts an app install when a user downloads and opens your app after interacting with your ad within the attribution window. Install events are captured via the Meta SDK integrated in your mobile app, which sends the installation signal back to Meta’s servers for attribution.
