A. Overview of App Open Ads
1/ What is an App Open Ad?
App open ads help to monetize your mobile app loading experience and serve when a user opens or switches back to your app.
App open ads are specially designed to seamlessly integrate into the app open or app switch context. The unique app open ad layout offers the best user experience for this placement.
App open ads use various ad materials for revenue enhancement: image, rich media, and video ads.

4/ Recommend implementation example
In the recommended example below, the app open ad is placed on the app’s loading screen. The loading screen is seen underneath the ad.

In the discouraged example below, the ad is placed after the loading screen and there is no content visible under the ad. These guidelines may lead publishers not to invalid activity and/or may result in Google disabling ad serving to your app.
B. Implementation best practices
#Tip1: Other guidelines
Don’t implement ads immediately before or after app open ads. Best way is to show your first app open ad after your users have used your app a few times.
Don’t implement app open ads on top of other ads. For example, the app open ad should not be placed on top of content that includes a banner ad.
Review your app’s performance and adjust the app open ad frequency capping accordingly.
App open ads perform best with apps that have a high frequency of opens per daily user. Apps that are opened more than once every 4 hours see the highest performance from app open ads. If you have an app that does not meet this criteria, consider using another ad format.
Show app open ads during times when your users would otherwise be waiting for your app to load.
If you don’t have a splash screen as part of your app open or switch experience, you may show an app open ad immediately upon app open or switch.
If you have a loading screen under the app open ad, and your loading screen completes loading before the ad is dismissed, you may want to dismiss your loading screen in the onAdDismissedFullScreenContent() method.
Google provided the policy that publishers aren’t allowed to place interstitial ads on app load and when exiting apps as interstitials should only be placed in between pages of app content.
