Why Offer Payouts Differ by Country and Device

Why do offer payouts differ by country and device?

Offer payouts differ by country and device because each advertiser decides where it wants new users, which devices its product runs on, and how much one result is worth to it in each market. A new user in a high-income country usually brings the advertiser more revenue, so it pays more for that user. An iPhone app can only be installed on iPhones and iPads, so its offer never appears on Android or desktop. The result: the same wall shows different offers, at different payouts, to a user in Texas on an iPhone and a user in Jakarta on an Android phone.

This guide explains the three causes, shows where your country and device mix appears in your Sharklio reports, and covers what you can honestly do about it. For the arithmetic from payout to user reward, read How offerwall payouts are calculated first.

Cause 1: advertisers set budgets and targets per country

Every offer starts with an advertiser’s plan. It picks the countries it wants, sets a payout per conversion for each, and sometimes a budget that runs out. This is how all online advertising works, not something special to offerwalls. Google’s help page on targeting ads to geographic locations describes how advertisers choose whole countries, regions, cities or a radius, and exclude the rest (checked on October 29, 2026). Offer advertisers make the same choices.

Three practical reasons sit behind those choices:

• Where the product works. A bank, a delivery app or a streaming service can only use customers in countries where it operates and is licensed.
• Where the budget earns back. Advertisers spend where a new user is worth more than the payout. Each market gets its own price, and markets that do not pay back are left out.
• Language and support. An app with no Spanish version will rarely pay for users in Mexico.

So a user in a country an advertiser skipped does not see a lower payout for that offer. They do not see the offer at all.

Cause 2: what a user is worth in different markets

Advertisers pay per result from what that result brings them: purchases, subscriptions, ad revenue, or a funded account. Those amounts depend heavily on incomes and spending, which vary enormously between countries.

• Income. The World Bank’s country and lending groups for its 2027 fiscal year class an economy as high income above $14,375 of gross national income per person in 2025, and as low income at $1,175 or less (checked on October 29, 2026). That is a gap of more than 12 times between the two thresholds alone.
• App spending. Sensor Tower’s State of Mobile 2026 puts global in-app purchase revenue at $167 billion in 2025 and says the United States stayed the largest market by revenue, with consumers spending nearly $60 billion.
• Local prices. Apple’s App Store Connect help on setting a price says developers can generate prices across the other 174 storefronts, adjusted for exchange rates and certain taxes, or choose their own price for individual countries or regions. A subscription priced lower in one market earns the advertiser less per subscriber there.

The tier labels you see in advertising are shorthand for this. Tier 1, 2 and 3 countries lists the common groupings, and Highest CPM countries shows how large the gaps are for ads. A lower price says nothing about the person: it reflects what advertisers earn back, not how real or loyal the user is.

Cause 3: iOS vs Android vs desktop, and how many offers fill the wall

Device matters in two ways: which offers exist for it, and what the advertiser pays on it.

How much each device matters depends on your audience. StatCounter’s mobile OS market share for the United States showed iOS at 53.59% and Android at 46.39% in September 2026, while its worldwide figures for the same month showed Android at 69.17% and iOS at 30.81%. On the same tracker’s desktop vs mobile share, desktop still made up 39.26% of worldwide web traffic that month (all checked on October 29, 2026).

Whether iPhone pays more than Android for a given offer is up to its advertiser and varies by country, so do not assume it. Check the offer itself, as shown in the next section.

Fill: when a user sees few offers

Fill is how many offers a user can actually be shown. A user in a country few advertisers target, on a device few offers support, may see a short list. If nothing matches, the Sharklio wall shows “No offers right now” and tells the user there are no offers for their country and device at the moment. That is not an error on your side. What is fill rate? explains the idea in general.

How country and device show up in your Sharklio reports

You can see your mix in four places. How to read your dashboard and reports covers every screen in detail.

1. Reports, Performance. Choose Countries or Devices in the row of groupings (next to Daily, Offers and Sub IDs). Each row shows Clicks, Conversions, Earnings, EPC, Conv. rate and Reversed. Devices are listed as Desktop, Android and iPhone or iPad. Click a row’s name to show those conversions, and use Export CSV to keep a copy.
2. Reports, Conversions. Every result shows the user’s IP address with a country flag, and the Country filter narrows the list to one market.
3. Offers. Filter by device (Desktop, Android, iOS) and by country. The Your payout column notes when a payout varies by country. Open an offer to see Your payout by country, or, when the offer has several versions, a Versions table with the countries, device and payout of each. Users see the version that fits their device and country.
4. Apps, your app, Design. On a live app, the live preview of your wall has a bar that reads “Preview: live offers for” a country “on” a device. Pick, for example, Brazil and Android, click Show, and you see the list those users get. Starting offers is turned off in the preview.

Outside the dashboard, the Reporting API returns statistics with group_by=country, and each transaction in its conversions list carries country and device. Your postback URL can receive the same values with the {country} and {device} macros, documented in the postback reference.

When the mix moves your earnings, not the offers

A change in where your users come from can move your total more than anything about the offers. Look at earnings per click by country and device before you decide the wall got worse.

Blended EPC fell from $0.0465 to $0.039, and earnings fell by about 16%, although no offer changed and no segment performed worse. In Performance, the Daily view would show the drop; Countries and Devices would show why. The new Brazilian users still added $40 that month. The answer is to keep them and also grow elsewhere, not to turn them away. eCPM and EPC explained has the formulas, and the offerwall earnings calculator lets you try your own mix.

Grow audiences in better-paying markets, honestly

You cannot change what advertisers pay in a country. You can change who finds your product, as long as they are real people who want it.

• Build for the markets you want. Content, support and an earn page in a market’s language draw users from there. A topic that matters to people in Canada or Germany will bring visitors from Canada or Germany.
• Cover the devices your audience uses. If your website audience is mostly on iPhones, a fast mobile layout matters more than desktop polish. If you have an app on one platform only, a version for the other opens a second set of offers. App store optimization helps people find it.
• Grow through your own channels. How to get traffic to a rewards website covers sources that bring real users.
• Keep the users you already have. Lower-paying markets are often large and loyal. How to monetize Tier 3 traffic shows how to earn more from them instead of chasing someone else’s audience.

Set one currency rate that is fair everywhere

On Sharklio, your conversion rate and split to user are set per app on the Currency tab, and they apply the same way in every country. The reward each user sees is calculated from what that completion pays you, so it already follows the market. With 1,000 coins per $1 and an 80% split, an offer that pays you $2.00 for a US user shows 1,600 coins, and the same offer paying $0.40 for a Brazilian user shows 320 coins (sample figures only). Each user receives the same share of what their own completion earned. That is the fair part.

Two mistakes break that balance:

• Raising the rate or split to make low-paying markets look generous. It raises rewards everywhere, and if your currency cashes out, you can end up handing out more than you earn. How to set your virtual currency exchange rate shows how to pick a rate you can sustain.
• Pricing your rewards catalog for one country only. If the cheapest cash-out only suits US users, users elsewhere may never reach it. Offer small rewards that people in your main markets can actually use.

Tell users plainly on your earn page that offers and rewards depend on their country and device. It prevents most “why does my friend see more coins?” tickets.

Do not block countries without a reason

You do not need to filter countries to protect your earnings. The wall only shows a user the offers that accept their country and device, so a lower-paying user costs you nothing. Turning them away removes earnings, not costs: in the example above, Brazil and India still brought in $120 in month two.

Good reasons to keep a country out of your own product exist, and they belong in your own sign-up and terms:

• Your service is not legal there, or a law you must follow, such as a sanctions rule, forbids serving it.
• You cannot deliver rewards there, for example no payout method you offer works in that country.
• You cannot meet a local rule, such as an age or consent requirement, for users there.

Fraud is rarely a good reason to block a whole nation. Fraud comes from accounts and devices, not passports, so act on the accounts. Stop multi-accounting and VPN abuse covers the signals. The same applies to offers: hide only what really does not fit your audience. How to choose the offers your users see explains hiding a whole offer or one version of it.
