App Users Who Engage with Rewarded Ads More Likely to Make In-App Purchases, Tapjoy Study Reports

Users who engage with rewarded ads are 4.5X more likely to make an in-app purchase, spend 326% more after engaging with ads

SAN FRANCISCO — August 1, 2017 — Mobile app developers have often wondered if rewarded ads take revenue away from In-App Purchases (IAPs). But new data out today from Tapjoy, the Maximum Impact Platform™ for mobile advertisers and app developers, shows that rewarded ads actually help increase IAP spend. The study, titled “Maximum Impact Report: The Impact of Rewarded Ads on IAP, Retention & Engagement,” revealed that users who engage with rewarded ads are 4.5 times more likely to make an in-app purchase than those who do not engage with ads. The report also found that user spend increases significantly after users interact with rewarded ads.

Rewarded advertisements — also known as “opt-in” ads — allow users to earn in-app currency or unlock premium content in exchange for watching videos or engaging with other types of advertising content. In a detailed analysis of eight apps with a high volume of Daily Active Users (DAU), Tapjoy found that seven of the apps showed significantly higher IAP conversion rates among users who engaged with ads versus those who did not. While the average increase was 4.5X, two of the apps experienced an increase of at least 9X — meaning that users were over nine times more likely to make an in-app purchase after they engaged with a rewarded ad.

The study also showed that users are likely to spend more money in the app if they first engage with a rewarded ad. In all eight apps studied, IAP spend increased significantly after users engaged with an ad — by an average of 326 percent. Across the apps studied, the boost in average spend per user ranged from just shy of 200 percent to over 500 percent.

“Some app developers fear that giving their users the option to earn currency through rewarded ads will reduce the likelihood of IAP or negatively impact user spend. Our data shows that not only do developers have no reason to worry about such cannibalization, but rewarded ads are actually conducive to IAP,” said Benjamin Chen, SVP & GM, Developer Relations at Tapjoy. “Our hypothesis is that rewarded ads serve as an initial introduction to an app’s in-game economy or premium content. Once users get a taste for it, they want more — and they’re willing to pay for it.”

Rewarded ads also appear to have a positive impact on user engagement, according to the study. Across all apps studied, the average number of daily sessions per user increased 34 percent among those that completed at least one rewarded ad.

Tapjoy had previously reported that engagement with rewarded advertising shows a high correlation with increase in retention rates. The company’s May 2017 Maximum Impact Report on “The Impact of Rewarded Ads on App Retention” found that app users who engage with rewarded ads during their first week demonstrate a 30-day retention rate about four times greater than the average.
