Interstitial video ads

An interstitial video ad is a full-screen video ad that appears in between experiences in an app.

• Placement: Interstitial
• Platform: mobile app, mobile web
• Initiation: Auto-play, sound on or off

Benefits of interstitial video ads

• Clicks are only counted if the user clicks the "Learn more" button. This prevents inflated click through rates, and protect from accidentally exiting the app.
• Ads are highly viewable since they are full screen. Active View can also be used to measure viewability.
• When in an app, interstitial video ads are only served in between experiences, never interrupting the user or content.
