How to Choose an Offerwall Provider in 2026

Most offerwall evaluations come down to a number that can’t actually be compared: eCPM. Every provider quotes one, every quoted figure is real, and putting two of them side by side tells you almost nothing about which will earn you more money.

This guide is about how to run the evaluation properly — what to compare instead, how to structure a head-to-head test that produces a trustworthy answer, and which contract terms quietly determine your revenue long after the integration is done.

If you want a shortlist of named platforms, our comparison of six monetization platforms covers that. If you want a checklist to run against a vendor call, we keep 15 questions for exactly that. This piece is the methodology that sits underneath both.

Why eCPM comparisons mislead

A quoted eCPM is a blended average, and four things underneath it vary enough between providers to make the comparison meaningless.

• Geographic mix. A provider whose publisher base skews heavily US and UK will quote a higher blended number than one with global distribution, without being better for your players. If 60% of your DAU is in Southeast Asia, a Tier 1–weighted average predicts nothing about your outcome.

• What counts as an impression. Some providers count an impression when the offerwall loads, others when a user opens it, others per offer displayed. The denominator changes, so the rate changes, with no difference in actual revenue.

• Currency conversion ratio. A generous reward ratio drives higher completion rates and a higher eCPM — funded by your economy, not theirs. Two providers can look different purely because one publisher priced rewards more aggressively.

• Placement quality. An offerwall behind a prominent store button performs differently than one buried in settings. Quoted averages come from a mix of both.

The metric that survives all four is ARPDAU contribution: how much incremental revenue per daily active user the provider adds to your game, measured on your own traffic. That’s the only number worth deciding on, and the only way to get it is to test.

The five dimensions that actually determine outcome

Before testing, use these to build a shortlist. Each one has a question worth asking and an answer pattern worth listening for.

1. Demand depth in your specific geographies

A player only completes offers they find worth doing. Thin inventory is the most common reason an offerwall underperforms, and it’s invisible until you’re live.

Ask: how many live offers are available in my top five countries, and what’s the mix across gaming, brand, subscription, and survey inventory?

Good answer: country-level counts with a category breakdown. Red flag: a global total, or an unwillingness to break it down by market.

2. Integration and ongoing maintenance cost

Launch effort is the smaller half of this. The larger half is what the integration costs you at every subsequent release.

Ask: is an SDK required, what breaks when I ship an update, and how do offer catalogue changes reach my players?

An SDK is a permanent dependency — bumped, re-tested, and occasionally debugged against conflicts. A web-based integration sits outside your build entirely, so updates propagate without you shipping anything. RevU takes the latter approach and most teams are live within hours, but the general point stands regardless of vendor: price the maintenance, not just the launch.

3. Fraud and traffic quality controls

This reads like a compliance topic and is actually a revenue one. Invalid traffic suppresses what advertisers will pay for your inventory, so a provider with weak controls costs you rate even when the fraud isn’t yours.

Ask: what validation happens before a conversion is approved, who absorbs the cost of a reversed conversion, and how are disputes handled?

The clawback answer matters most and is the one most often glossed over. Our guide to offerwall fraud prevention covers what good controls look like in detail.

4. Reporting granularity

You cannot optimize what you cannot segment. Daily revenue totals are not reporting.

Ask: can I see performance by offer, placement, country, and platform, in near real time, and can I export it?

Red flag: aggregated dashboards with no export and no placement-level breakdown. If you can’t isolate a placement, you can’t tell a bad placement from a bad provider.

5. Contract flexibility

Covered in its own section below, because it’s where the most expensive mistakes get made.

How to run a head-to-head test that produces a real answer

This is the part most publishers get wrong, usually by running the new provider for a month, comparing it to last month, and drawing a conclusion that seasonality alone could explain. A defensible test has six properties.

• Split by user, not by time. Randomly assign users to provider A or provider B and run both simultaneously. Sequential testing confounds your result with seasonality, live-ops events, and whatever else changed between periods. If you can only test sequentially, at minimum avoid comparing a holiday period against a normal one.

• Hold your currency ratio constant. Same reward value per dollar of payout on both sides. If you change the ratio between arms, you’re testing your own pricing, not the provider.

• Keep placements identical. Same entry points, same prominence, same copy. Placement effects are large enough to swamp provider differences.

• Run at least two to four weeks. New offerwalls get a novelty bump as your existing players discover them and work through the offers that appeal to them most. Week one systematically overstates steady-state performance, so discard it or run long enough that it doesn’t dominate.

• Measure ARPDAU, not eCPM. A provider can win on eCPM while losing on revenue if fewer players engage with the wall at all. Total incremental revenue per daily active user is the outcome you care about.

• Watch the incumbent’s numbers too. If you’re adding rather than replacing, the question isn’t just what the new provider earns — it’s whether total offerwall revenue rose. This is the difference between incremental revenue and redistributed revenue, and it’s frequently additive: Kongregate saw a 650% increase in iOS offerwall revenue after adding RevU alongside an existing partner, with no measurable decline in the incumbent’s performance. We’ve written up the case for running two separately.

One caution on reading results: if your daily offerwall engagement is small, a two-week test may not produce a difference you can distinguish from noise. When arms land within a few percent of each other, the honest conclusion is usually “no detectable difference,” and you should decide on the other four dimensions instead of over-reading the number.

Contract terms that quietly cost you money

The commercial terms get less scrutiny than the tech and are more likely to constrain you later.

• Exclusivity. Any clause preventing you from running a second offerwall forecloses a revenue option that is often additive. If exclusivity is requested, it should be paid for.

• Clawback liability. When an advertiser reverses a conversion, who absorbs it — and is there a cap or a time limit on how far back reversals can reach? Uncapped, unlimited clawback exposure is a genuine risk.

• Payment terms. Net 30 versus net 60 is a real working-capital difference at scale, as is whether there’s a minimum payout threshold that can strand revenue.

• Data ownership and portability. Can you export your historical performance data if you leave? Losing your own baseline makes the next evaluation much harder.

• Termination and notice. How much notice to exit, and does the offerwall keep serving during the notice period?

• Rate change rights. Whether revenue share can be adjusted unilaterally, and with what notice.

What changed for 2026

Two shifts are worth factoring into a decision made this year.

Web storefronts became a real surface. Following the April 2025 US District Court ruling in Epic v. Apple, developers can link players from inside iOS apps to their own web shops. The commission question is still unsettled while Apple pursues Supreme Court review, but studios are building regardless. That makes surface coverage a live evaluation criterion rather than a footnote: a provider that only works inside a mobile app covers less of your revenue surface each year, while an offerwall placed in a web shop reaches players who are already there to acquire currency. The two reinforce each other.

Offer ranking got more automated. Most providers now personalize which offers surface to which users. This is genuinely valuable and also hard to evaluate from outside, since every vendor claims it. The practical test is whether they’ll show you completion-rate lift from personalization on comparable publishers, rather than describing the capability.

Red flags

• Blended global eCPM quoted without country-level detail when asked.

• Reluctance to permit a split test, or pressure to judge on week-one numbers.

• Exclusivity requested without compensation.

• No placement-level reporting or data export.

• Vague answers on who absorbs clawbacks.

• No named contact after onboarding — support that exists only during the sales process.

• Player support for missing rewards pushed entirely onto your team.

A scoring framework

If you’re comparing more than two providers, score each dimension 1–5 and weight roughly as follows. The weights matter more than the precision.

Demand depth carries the most weight because it’s the constraint you can’t optimize your way out of. Everything else — placement, reward pricing, promotional timing — is work you can do after signing. A catalogue that doesn’t serve your players is not.

After you choose

Selection is maybe a third of the outcome. The rest is configuration, and two settings do most of the work.

Your currency conversion ratio should be anchored to what players already pay for currency through IAP. Priced too low, completion rates collapse and you conclude the provider underperformed. Priced too high, you inflate your economy and undercut your own store.

Then placement: entry points at moments of existing intent — the store screen, soft failure states, onboarding — move revenue more than almost any other lever available to you after launch.

FAQs

What is the most important factor when choosing an offerwall provider?

Offer supply in the countries where your players actually are. Everything else can be tuned after launch; a catalogue that doesn’t appeal to your specific audience cannot. Ask for country-level offer counts and category breakdowns before comparing anything else.

How long should an offerwall test run?

Two to four weeks minimum, split by user rather than by time period. Week one typically overstates performance because of a novelty effect as existing players discover the wall, so either discard it or run long enough that it doesn’t dominate the result.

Can I run two offerwalls at the same time?

Yes, unless your contract forbids it, and the result is frequently additive rather than a split of existing revenue — different networks carry different advertisers and appeal to different players. Check for exclusivity clauses before assuming you’re free to.

Why do quoted eCPMs vary so much between providers?

Because they measure different things. Geographic mix, what counts as an impression, publisher currency conversion ratios, and placement quality all move the number independently of how much revenue you’d actually earn. Use quoted eCPM to build a shortlist, never to make the final decision.

Does adding an offerwall hurt in-app purchase revenue?

Not when the conversion ratio is anchored to your IAP pricing. Players who intended to buy still buy; the offerwall mainly monetizes players who never would have. Cannibalization is a configuration error, not a property of the format.

How quickly can an offerwall go live?

SDK-based integrations generally take one to several weeks including QA, and add maintenance at each release. Web-based integrations remove the SDK dependency entirely and can typically be deployed in hours to a few days.

The takeaway

The providers worth working with will encourage a split test, break their numbers down by country without being pushed twice, and tell you plainly who absorbs a clawback. Those three behaviours correlate with everything else you care about, and they’re observable before you sign.

RevU is non-exclusive by design, integrates without an SDK across mobile, desktop, and web, and provides placement-level reporting — which means a clean test against your incumbent is straightforward to run. If you’d like to set one up, see how RevU monetization works or talk to our team.
