About the “Long CPE Rewards” offered by SKYFLAG
A rewards ad where a reward is paid when a user reaches a specific achievement point within the app.
By guiding users to a specific point where they can find the content interesting, you can expect high long-term retention and monetization rates.
This model allows you for acquisition of highly engaged users who continue to actively use the app even after reaching a certain milestone. Furthermore, unlike traditional CPC and CPI models, no advertising costs are incurred for users who churn, resulting in an extremely high return on advertising spend.
