What is CPE?

Cost Per Engagement Explained

Cost Per Engagement (CPE) is an advanced performance model where advertisers pay for specific in-app user actions beyond the install. Whether that's completing a tutorial, making an in-app purchase, finishing a registration form, or reaching a game milestone — you define the event, and you only pay when it happens. CPE delivers more qualified users than CPI at a higher-quality cost point.
