Create an interstitial ad unit

Interstitial ad units show full-page ads in your app. Place them at natural breaks & transitions in your app's interface, such as after level completion in a gaming app.

Interstitial ad units can show the following types of ads: Text, image & rich media and Video.

Note: The timing of a close option for interstitials depends on whether your interstitials are opted into video. If they are are opted into video, some ads may have up to a 5-second delay before providing a close option. By policy, interstitials that don’t allow video will have an immediate close option. The Google Mobile Ads SDK will begin enforcing this more aggressively with releases of the Google Mobile Ads SDK: 7.21 or later for iOS, and 11.4 or later for Android.
