I'll walk you through the 9 best interstitial ad networks for 2025, packed with tips to amp up your ad strategy and cash in big time. Let's get your earnings sorted!
What are Interstitial Ad Networks?
An interstitial ad network is a platform connecting advertisers with publishers to display full-screen ads at natural transition points within a mobile app or website. These ads appear between activities, such as after a level in a game is completed or while a new webpage is loading.
For those looking to monetize their digital content, these networks are highly effective. Due to their full-screen size, interstitial ads capture a user's full attention, which often leads to higher engagement and click-through rates. This translates into greater revenue for publishers compared to other, less prominent ad formats like banners.
The ad network manages the entire process—from serving and targeting ads to tracking performance and handling payments—providing a streamlined solution for both advertisers and publishers.
