You may have noticed that your mobile app installs campaign isn't tracking any app installs.

• Before you can track any mobile app installs, add the Facebook SDK to the app. After you implement the Facebook SDK in the app, create a new App Installs ad campaign. Check with the app developer and make sure that they've followed all the steps for setting up the Facebook SDK in the app.
• If you don't have any app installs within the last 28 days, you won't be able to optimise for app installs. Instead, your app installs campaign will be optimised for link clicks until an app install takes place.

You can access interactive developer tools to help verify your app with the App Ads Helper.

You can learn more about measuring app installs in our app developer's guide.
