What is an Offerwall? Complete Guide for Mobile Developers

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 another game — and in return they receive virtual currency, premium content, or another in-app reward. The developer earns CPA or CPI revenue from the completed action.

Put simply: an offerwall is the screen where your non-paying users exchange attention for money, and the developer gets paid for the completed task rather than the impression. That distinction — paid for the action, not the view — is what separates an offerwall from every other ad format in your app.

What is an offerwall, in one sentence

An offerwall is an in-app list of offer tasks that a user completes in exchange for a reward, where the publisher is paid a CPA or CPI for the verified completion. If you have seen an offerwall in a mobile game, it is almost always the screen with a grid of app-install or survey offers, each showing the reward you get for finishing it.

How an offerwall works, step by step

1. The user opens the offerwall from inside your app. It is opt-in, never forced.
2. They browse the available offers — app installs, surveys, sign-ups, game milestones.
3. They select one and complete the action.
4. The advertiser reports the conversion to the tracking engine.
5. The engine validates it — fraud check, deduplication, device intelligence.
6. A server-to-server (S2S) postback is sent to your server with the offer ID, payout, status and player ID.
7. Your server credits the user with the reward.

That last step is the one most publishers get wrong. If the reward is credited on the client, a modified app can claim it without doing anything. Server-side validation means the reward only appears after the platform confirms the conversion actually happened.

What an offerwall is used for

An offerwall is built to monetize the segment of your audience that will never make an in-app purchase. In most mobile games and apps, roughly 95% of users never spend money. Forcing them into a paywall gets you nothing; giving them an opt-in way to earn rewards instead converts them from zero-revenue users into revenue-generating ones.

Typical uses of an offerwall include:

• Virtual currency top-ups — coins, gems, lives or energy bought with offer completions instead of money.
• Premium content unlocks — a level, a skin, a booster or a story chapter.
• Subscription trial extensions — extra days of premium access earned by installing a partner app.
• Trial or premium access — granting premium features in exchange for a completed offer.

Offerwall vs other ad formats

This is the comparison that matters most, because the formats are not substitutes for each other — they capture different user behavior.

The pattern is clear: the more effort the user spends, the more you earn. A rewarded video pays for 15 to 30 seconds of attention. An offerwall pays for a completed install, a finished survey or a signed-up account — which is worth multiples more because the advertiser is paying for a proven outcome, not a view.

The practical consequence is that an offerwall and rewarded video are complementary rather than competing. Rewarded video monetises the session you already have. An offerwall monetises the user who will not spend money but will install another app.

What an offerwall survey is

“Offerwall survey” is one of the most searched terms in this category, and it refers to the survey offers that appear inside an offerwall — short questionnaires that a user completes for payment. These are one of the highest-converting offer types for mobile publishers because the user has already committed to completing a task, and a survey takes two to five minutes rather than requiring an app install and a first launch.

Surveys also tend to perform well in markets where app installs convert poorly. If your audience is heavily in South Asia, Southeast Asia, or Latin America, survey-weighted offer mixes frequently outperform install-weighted ones.

Offerwall vs offerwall: what actually separates the platforms

If you are comparing offerwall providers, these are the five things that determine your revenue, in order of impact:

1. eCPM for your specific geos. A headline eCPM number is meaningless. What matters is the eCPM in the countries your users are actually in. Some platforms quote tier-1 US rates that never apply to your traffic.
2. Server-side reward validation. Client-side reward crediting is fraud waiting to happen.
3. SDK coverage and integration effort. Native SDKs for the platforms you actually ship on, and a postback API for anything else.
4. Offer mix quality. A platform with 1,200 live offers where only 200 will convert for your audience is not a 1,200-offer platform for you.
5. Payout speed and minimum threshold. Weekly payouts with a low threshold beat monthly payouts with a high one, especially for smaller publishers.

How to design an offerwall that does not hurt retention

An offerwall can raise ARPDAU and still lose you users. The difference is in the placement and the framing.

Do

• Make it opt-in and never interrupt a paying user with it.
• Place it near your IAP store, where a user has already signalled they want more currency.
• Show the exact reward on every offer card, not a generic “Get reward”.
• Show remaining offer count and sort by reward value so the best offer is obvious.
• Credit rewards instantly on a valid postback so the loop feels instant.

Do not

• Force the offerwall open on first launch or at level completion.
• Use vague reward labels like “Earn 500 coins” with hidden conditions.
• Hide the offerwall behind a five-level navigation maze.
• Reward the same task repeatedly without a cap — users notice and disengage.

Our guide to boosting ARPDAU with offerwalls without hurting retention covers the measurement side — how to track Day 1, Day 7 and Day 30 retention alongside revenue so you can tell whether a placement is actually working.

How much can an offerwall earn?

Roughly, an offerwall is worth $20 to $100+ eCPM because you are paid per completed action. Applied to a realistic user base, that is where the ARPDAU numbers come from. A game with 100,000 daily active users placing an offerwall as an optional way to earn premium currency can plausibly add meaningful revenue on top of IAP without touching what your paying users spend.

The practical calculation is straightforward: take your DAU, multiply by the percentage who engage with the offerwall (typically 3–8% of users when it is a genuine reward path rather than a forced screen), multiply by the per-engaged-user conversion rate, and multiply by the platform’s eCPM. The complete ARPDAU guide walks through this with the benchmark numbers.

How to integrate an offerwall

The integration itself is deliberately small, because the moment a publisher’s onboarding takes more than an afternoon, the offerwall never gets launched at all.

1. Create a publisher account and get API keys.
2. Add the SDK for your platform — Unity, React Native, Android, iOS, Flutter or Web.
3. Configure the offerwall placement — position, reward mapping, and which offer types to show.
4. Point your server at the S2S postback endpoint and validate each reward server-side.
5. Place the offerwall entry point where you want users to find it, then watch the dashboard.

The offerwall SDK integration timeline covers step 3 and 4 in detail, including the postback parameters you should validate.

Offerwall FAQ

What is an offerwall in mobile apps?

An offerwall is a screen inside a mobile app or game listing tasks — app installs, surveys, sign-ups, game milestones — that users complete in exchange for in-app rewards. The publisher is paid a CPA or CPI for each verified completion, not for the view.

Is an offerwall better than rewarded video?

They monetise different behaviour, so most apps benefit from running both. Rewarded video pays $5–$30 eCPM for 15–30 seconds of attention; an offerwall pays $20–$100+ eCPM for a completed task. Rewarded video monetises the current session, an offerwall monetises the user who will never spend money. Our offerwall vs rewarded video comparison covers when to prioritise each.

What is an offerwall survey?

A survey offer is a short questionnaire inside the offerwall that the user completes for payment. It is one of the highest-converting offer types and often outperforms app-install offers in markets where install conversion is weak.

Do offerwalls hurt retention?

Not if the offerwall is opt-in and framed as a reward path rather than an ad. Forced offerwalls and vague reward labels are what cause retention damage. Track retention alongside ARPDAU after launch — our guide shows the measurement approach.

How is the reward validated?

The platform sends a server-to-server postback to your endpoint containing the offer ID, payout, status, player ID and reward amount. Your server validates and credits the reward. If you credit on the client instead, a modified app can claim rewards without doing anything.

What is the difference between an offerwall and a rewarded offer?

They are the same mechanism. A “rewarded offer” is the individual task inside an offerwall — a rewarded video, an app install or a survey — that pays on completion rather than on view.

Can I run an offerwall alongside in-app purchases?

Yes, and that is the intended usage. An offerwall monetises the roughly 95% of users who never make an in-app purchase, so it adds revenue rather than cannibalising IAP. This guide covers how to layer offerwalls with IAP and ads without them competing.
