Interstitial Ad
01 Definition
Interstitial Ad meaning: A full-screen ad shown at natural break points in an app or website.
An interstitial ad covers the whole screen and appears between content, such as after finishing a game level or between page views. Users can usually close it after a few seconds. Because it interrupts the experience, poor timing or placement can frustrate users and hurt engagement.

Why it matters
How Interstitial Ad fits the work
Interstitials capture full attention at moments when a user is already pausing, which makes them a high-impact format for awareness and app installs.
In context
A mobile game shows a full-screen interstitial ad after the player completes a level, with a close button appearing after five seconds.
Practical note
Show interstitials at natural stops, not mid-task. Google policies penalize intrusive interstitials that block content, especially on mobile, and can affect search visibility.
