What is an Offerwall? Complete Guide for Mobile Developers
What is an Offerwall?
An offerwall is a user-facing interface inside a mobile app or game that presents a list of rewarded actions. Users choose an action to complete — installing an app, completing a survey, signing up for a service, reaching a level in a game — and in return, they receive virtual currency, premium content, or other in-app rewards. The developer earns CPA/CPI revenue from the completed action.
How Offerwalls Work
- User opens the offerwall from within the app (opt-in, never forced)
- User browses available offers (installs, surveys, signups, game milestones)
- User selects and completes an action
- Advertiser reports the conversion to the tracking engine
- Tracking engine validates the conversion (fraud check, dedup)
- S2S postback sent to developer’s server
- Developer’s server credits the user with the reward
The offerwall is the surface. The platform behind it — tracking, validation, analytics, fraud monitoring — is the infrastructure. Perkox provides both.
Offerwall vs Other Ad Formats
| Format | Revenue Model | Typical eCPM | User Action |
|---|---|---|---|
| Banner | CPM | $0.50–$3 | View |
| Interstitial | CPM | $3–$10 | View/Close |
| Rewarded Video | CPM | $5–$30 | Watch video |
| Offerwall | CPA/CPI | $20–$100+ | Complete action |
Offerwall UX Best Practices
Do: Make it opt-in. Place near IAP store. Show clear reward labels. Show completion progress for multi-step offers. Suppress for recent IAP users.
Don’t: Interrupt gameplay with popups. Hide reward amounts. Show blank loading screens. Force users to the offerwall.
FAQ
Is an offerwall the same as rewarded video? No. Rewarded video pays per impression (CPM). Offerwalls pay per completed action (CPA/CPI).
Does an offerwall need an SDK? Some platforms offer SDK-free web-based offerwalls, but native SDK integration (like Perkox’s Android SDK) provides better performance and UX.
Which platforms should I look for? Look for server-side validation, fraud protection, SDK breadth (Android, iOS, Unity, Flutter, React Native), and self-serve access.
