Introduction
Choosing the right monetization model is one of the most important decisions app developers and publishers face in 2025. With increasing competition and changing advertising regulations, selecting the wrong model can lead to low revenue, poor user experience, and wasted traffic.
Two of the most popular monetization models used by offerwall platforms today are CPA (Cost Per Action) and CPI (Cost Per Install). While both models can be highly profitable, they serve different goals and audiences.
This guide explains the differences between CPA and CPI offerwalls, their advantages and disadvantages, and how to choose the best option for your app or website.
What Is a CPI Offerwall?
A CPI (Cost Per Install) offerwall rewards users for installing and opening an advertised mobile application. These offers are simple, fast to complete, and highly popular among users.
Key Characteristics of CPI Offerwalls
- Low entry barrier for users - Simple install actions require minimal effort
- Fast completion time - Users can complete offers quickly
- High conversion rates - Many users are willing to install apps for rewards
- Popular in gaming and reward-based apps - Especially effective for casual user engagement
CPI offerwalls are especially effective for apps with a large volume of casual users who prefer quick, simple actions over more complex engagements.
Best For
CPI offerwalls work exceptionally well in gaming apps, reward-based platforms, and apps targeting emerging markets where users may be more willing to try new applications.
What Is a CPA Offerwall?
A CPA (Cost Per Action) offerwall rewards users for completing a specific action beyond an install. This could include registering an account, completing a survey, subscribing to a service, or making a purchase.
Key Characteristics of CPA Offerwalls
- Higher payouts per conversion - Advertisers pay more for valuable actions
- More complex user actions - Requires greater user commitment
- Strong advertiser value - Delivers qualified leads and customers
- Higher long-term revenue potential - Builds sustainable monetization streams
CPA offerwalls are commonly used by finance, e-commerce, and subscription-based advertisers who seek qualified leads rather than simple app installs.
CPA vs CPI: Key Differences
User Action
CPI: Simple app install | CPA: Complex actions like registration or purchase
Payout Structure
CPI: Lower per action | CPA: Higher per completed action
User Commitment
CPI: Low commitment | CPA: Higher user engagement required
Conversion Time
CPI: Fast completion | CPA: Longer conversion cycles
The main difference between CPA and CPI offerwalls lies in the level of user commitment and payout structure. CPI offers prioritize volume and simplicity, while CPA offers focus on quality actions and higher value conversions. The choice depends on your audience, app category, and monetization goals.
Which Offerwall Model Generates More Revenue?
There is no one-size-fits-all answer. However, in most cases, CPA offerwalls generate higher revenue per user, while CPI offerwalls generate higher total conversions.
Apps with highly engaged users often benefit more from CPA models, while apps with large user bases and high traffic volumes perform better with CPI.
CPA Revenue Potential
Higher payouts per conversion but lower volume. Ideal for quality-focused monetization.
CPI Revenue Potential
Lower payouts per action but higher volume. Perfect for scale-driven monetization.
Hybrid Approach
Combining both models often yields the best overall revenue performance.
Audience Matters
Your specific user base and app category significantly impact which model performs better.
"We found that our utility app performed better with CPA offers, generating 60% higher revenue per user compared to CPI. However, our gaming app saw 3x more conversions with CPI offers. Testing both models is essential."
