Interstitial ads are full-screen placements between natural transition points in the user experience of a site, app, or game. These types of ads can include video, image and text, and rich media features.

When a user sees an interstitial, he or she either taps on the ad and is taken to the ad’s destination or closes the ad and continues his activities within the application. Interstitials are considered more engaging than other ad formats because they offer a higher level of interaction with the users.
