A survey of mobile publishers worldwide—most of them focused on gaming apps—found that rewarded video ads are the most effective way to generate revenue.

In the March 2017 AdColony survey, rewarded video ads—which are ads that give users rewards, generally in the form of credit for games being played in apps—were rated the most effective way to monetize apps. Rewarded video outranked not only other ad formats, but also non-advertising tactics like in-app purchases and subscriptions.
