With games like Jewel Star and Slots Pro, Rolling Donut provides hours of entertainment to millions of users worldwide. The app maker turned to Vungle to maximize ad revenue with video ads on the Windows platform.
Increasing their eCPM and fill rates were high priorities for Rolling Donut. “Other ad networks we tried had global fill rates that could sometimes drop into single digits,” says Jake Poznanski, co-founder, Rolling Donut. “Not having enough ads to fill demand meant that we were often missing out on up to 90 percent of our potential global ad revenue. This is a shame because our Windows users are some of the most engaged.” Furthermore, the video ads themselves had to be relevant to users, otherwise they’d risk harming overall engagement.
Vungle’s ad optimization team worked with Rolling Donut to create a program designed to improve fill rates, lift eCPM and enhance user engagement. Rolling Donut integrated rewarded ads into Jewel Star that would give players a chance to earn bonus moves when they needed them most. It also implemented interstitial ads in its other games that would play at natural breaks in gameplay.
Using Vungle on Windows, Rolling Donut nearly doubled Jewel Star’s eCPM compared to other ad networks on different platforms. Vungle also boosted global fill rates by three to five times what it was before, allowing Rolling Dount to capture more ad revenue. “Vungle’s huge boost to our fill provided a more consistent user experience and increased our revenue about 15 percent.”
The rewarded ads also kept Jewel Star players more engaged by offering them useful rewards, and increased their overall time in-app. Rolling Donut also found another benefit to Vungle’s SDK in its ability to control the maximum length of each video ad that appears. “This is important for online games with multiple players,” Poznanski says. “If our users don’t see the same length ad at the same time, then the games can get out of sync.”
