Mobile app engagement ads take users to a customized location within your app. These engagement ads have a call to action button such as scheduling an appointment, buying a product, or unlocking a level in a mobile game. This is similar to the website conversions ad we talked about earlier except it’s dealing with mobile apps.
Before you start your campaign, you must register your app and configure the app settings. For more information on this go to: https://developers.facebook.com/docs/ads-for-apps/mobile-app-ads-engagement
When you’re ready to start a new campaign, go to your Facebook page after you have logged on and click “Build Audience” at the top right of your page. Click on “Use Ads Manager” and click “Create Ad” at the top right of your page. Click on “App Engagement” from the list.
Insert your app URL from Google Play or the App Store and click continue. Choose your audience, set a budget and place your order.
