You’ve designed a great app and now you want to figure out how to keep your users engaged. Rewarded ad units are a great option to engage users and keep them coming back to your app. Users are rewarded with something valuable in your app in exchange for participating with an ad (a video or a survey, for example). This could be in the form of game currency for a gaming app, for example. or new filters and stickers in a photo app. These types of ad units provide instant gratification for users and leave consumers with a positive impression of your app.
