Ad Units Available In MAS

MAS gives app developers the ability to monetize their apps through mobile app advertising. This can be in the form of banner ads, interstitial ads, and rewarded video ads. Ads integrate directly into the app experience and may complement the in-app economy to ensure a non-disruptive user experience as well as increased engagement.

Top network advertisers serve these ads, and you get paid every time your users interact with any of the ads in your app. 

When monetizing your app, creating a mix of ad units helps in building a strong monetization strategy. You get to choose your ad units from the extensive portfolio of ad formats available with MAS.


An interstitial ad can be a full-screen static, a video or an interactive (playable) ad unit that gives users the option to exit and skip. These ads engage users with rich content at natural pauses in an app’s flow; They ensure minimum disruption to user experience while maximizing engagement and revenue. 
This is what an interstitial ad looks like:

Benefits of interstitial ads

  • Engaging content
    • Full-screen size
    • Media content can be static, video-based or interactive
