What is in-app advertising?

In-app advertising is a popular monetization strategy for app developers, in which app developers get paid to serve ads on their app.

The mobile app ads are served through a mobile app advertising network, which connects advertisers and developers. The app requests an ad from the network, and the network uses algorithms to identify and deliver the highest paying ad to the user in real time.

There are many different types of mobile ad formats app developers can integrate into their app in order to increase app monetization, including video ad units, mobile app display ads, and native mobile app ads.

Benefits of in-app advertising

Make more money for your app

When combining with in-app purchases, mobile app advertising works as an additional strategy to make money for your app. In fact, eCPMs can be as high as a -0 for some ad units.

Improve user experience

Seamlessly integrate mobile app ads into your game loop to create a positive experience for your users. For example, offer users rewards in exchange for watching or interacting with ads at specific points in the app lifecycle.

Increase in-app purchases

Drive in-app purchases with ad units that work as part of your in-app economy. Users who engage with rewarded ads, for example, are up to 6x more likely to make an in-app purchase.

Boost user engagement and retention

In-app ads that are tailored to your game, and integrated in the right places with the right capping and pacing, can improve user retention, in-app engagement, and lifetime value.

Mobile app ads

Playable ads

Playable ads are mini-games users can try out before they decide to install. They’re always enjoyable, make for a good user experience, and deliver the highest eCPMs in the industry.

Rewarded video ads

Rewarded video ads give users a clear value exchange – users watch a video ad and receive rewards in return. They’re opt-in, boost in-app purchases, and encourage users to return.


Offerwalls act as a mini-store in your app, which lists out tasks users can complete in exchange for receiving in in-app reward. They’re entirely user-initiated, significantly extend session length, and deliver industry leading eCPMs.


Interstitial ads engage users with rich, customizable, and appealing static or in app video ads at natural pauses in an app’s flow, ensuring minimum disruption to user experience.
