MultiNotes has been using Easy Monetization, Yandex’s all-in-one mobile ad monetization service, for over two years. Over that time, the Easy Monetization team has done more than simply manage the app’s monetization. They’ve continuously identified new opportunities to increase revenue and improve performance. Here’s how a targeted optimization of ad network settings increased ARPDAU by 58% — without a single change to the product itself.

MultiNotes is an Android notes and reminders app with over 5 million installs. It helps users organize and store text notes, photos, videos, voice recordings, and documents, create topic boards, and set reminders.

The app is available on Google Play and Huawei AppGallery. Ad monetization is the app’s primary revenue stream. MultiNotes is developed and maintained by Mikhail Kadykov, the app’s founder and sole developer.

MultiNotes has been an Easy Monetization partner since 2023. As part of its ongoing optimization efforts, the Easy Monetization team regularly reviews monetization performance and looks for new ways to increase revenue.

During a routine audit in March 2026, the team found that some ad networks were responding to requests more slowly than others. As a result, not all ad requests were making it to the impression stage, limiting the app’s revenue potential.

At the time of the audit, ARPDAU stood at $0.0011. This was a stable result, but the team saw room for further growth without any product changes or modifications to the user journey.

To unlock this potential, the team needed to:

• Reduce latency in ad request processing
• Bring more ad networks into the auction
• Improve ad unit fill rates and increase impression volume
• Grow ARPDAU using existing traffic

To reduce ad network latency and grow ad revenue, the Easy Monetization team:

• Implemented proprietary optimization technologies to improve ad network response times
• Fine-tuned monetization settings for the MultiNotes audience
• Added four ad networks: Digital Turbine, Unity Ads, ironSource, and Chartboost
• Prepared recommendations on updating the SDK and releasing a new version of the app

Once the updated ad network settings were fully rolled out, the Easy Monetization team compared performance before and after the changes. ARPDAU increased by 58%, with no changes to the product or its audience.

The increase was driven by the addition of new ad networks and a higher share of ad requests successfully reaching the impression stage. With faster response times, ad networks were able to participate in the auction more effectively, which directly boosted monetization revenue.
