- Geo-targeting limits an ad or offer to people in chosen locations, most often detected from the IP address of their connection.
- Location detection is a best estimate, and VPNs, proxies and privacy relays can hide or change the country a site sees.
- Payouts differ by country because advertisers pay what a user there is worth to them, so the same offer can pay very different amounts.
What is geo-targeting?
Geo-targeting, or geotargeting, is showing an ad or an offer only to people in chosen locations, such as a country, a region or a city. The ad platform or offerwall estimates where each user is, usually from the IP address of their connection, and hides anything the user’s location does not qualify for. In affiliate marketing, country targeting is the most common form: every offer lists the countries the advertiser will pay for.
Advertisers use it because a user is worth different amounts in different places, and because many products are only sold, licensed or legal in some countries.
How geo-targeting works
Most systems combine several signals, but the IP address does most of the work on the web.
- The user connects. Every request to a site or app comes from a public IP address, assigned by an internet or mobile provider.
- The address is looked up. IP geolocation databases map address ranges to countries and regions, based on how those ranges are registered and used.
- Other signals are checked. Device language, time zone, app store country, account settings and, with permission, device GPS can confirm or contradict the IP country.
- The targeting rule is applied. The user sees only the ads or offers set for that location and device.
- The result is checked again. Many advertisers recheck the country at conversion time and reject results from outside their target list.
Ad platforms are open about this being an estimate. Google Ads Help says location targeting is based on signals including users’ settings, devices and behavior, that it is a best effort, and that 100% accuracy is not guaranteed (checked on November 5, 2026). The same page lets advertisers choose between people who are in a location and people who are in or interested in it.
The limits of IP-based country detection
Country-level detection is usually reliable on normal home and mobile connections. City-level detection is much rougher. And some connections hide the real location on purpose.
| Connection | What the site sees | Effect on targeting |
|---|---|---|
| Home Wi-Fi or mobile data | The provider’s address in the user’s country | Country is usually right; city can be off |
| VPN | The VPN server’s address, in any country the user picks | Country can be faked |
| Proxy or residential proxy | Someone else’s address | Country can be faked and looks like a real household |
| Tor | A Tor exit node, often in another country | Location hidden |
| Data center or cloud | A hosting company’s address | Not a real user connection in most cases |
| Privacy relay | A relay address in the user’s approximate region | Country is kept, exact address is not |
Privacy relays are a middle case. Apple’s iCloud Private Relay and Privacy page says websites see only an IP address that matches an approximate regional area, not a particular person, and that users can choose the less precise “Use country and time zone” setting. What is IP reputation? explains how sites tell a VPN or hosting address from a home connection.
Why payouts differ by country
Advertisers pay what a user is worth to them, and that depends on where the user lives. Incomes, spending in apps and online stores, card use and competition between advertisers all vary by country. That is why networks group countries into Tier 1, 2 and 3, and why ad prices follow the same pattern, as the highest CPM countries shows. App install prices do too: see cost per install by country.
Illustrative example: one offer, three countries
A strategy game pays for players who reach level 10. It sets $6.00 per result in the United States, $2.50 in Poland and $0.60 in the Philippines, and pays nothing anywhere else. A US user on a VPN set to the Philippines would see the $0.60 version; a Philippine user on a US VPN would see $6.00 but the result would be rejected at the country check. Sample figures only.
Device matters as much as country. Many offers are set for Android only, iOS only or desktop only, so two users in the same country can see different lists. How country and device mix change earnings shows what this means for a publisher’s income.
Geo-targeting and privacy
Country detection needs the IP address, and in many places an IP address is personal data. The GDPR, in Recital 30, names internet protocol addresses among the online identifiers that can be linked to people and used to profile and identify them. If you serve users in the EU or UK, your privacy policy should say that you or your partners process IP addresses, what for, and with whom you share them.
Coarse country lookups for fraud prevention and offer eligibility are a different thing from precise device location. Precise GPS location needs the user’s permission on Android and iOS, and most offer targeting does not need it. Offerwalls and GDPR and what data the wall collects cover the details. This is general information, not legal advice.
Common geo-targeting mistakes
What goes wrong
Treating the IP country as certain and never rechecking it. Letting VPN and proxy users through, then losing the results to advertiser rejections. Showing the same offer list in every country, so users click offers they cannot complete. Testing your own wall on a VPN or a cloud device and assuming the empty list is a bug. Collecting precise location when country is all you need.
For campaigns, the reverse mistake is common: buying every country at one bid. Set budgets and prices per country, as how to choose campaign countries explains.
How geo-targeting works on an offerwall
On an offerwall, geo-targeting decides which offers each user sees and what they pay. A good wall only lists offers the user’s country and device qualify for, and it blocks connections that hide the location, because those results would be rejected anyway. Moonetix is a pay-per-result affiliate network, and its offerwall works this way: offers depend on the user’s country and device, and users on VPNs, proxies, Tor or data center networks are blocked from the wall. If a user says the wall is empty or blocked, VPN or proxy detected on an offerwall walks them through the fix. The honest limit: a publisher whose users mostly come from countries with few offers will see fewer offers and lower payouts, whatever wall they use.
Country and device targeting on Moonetix
The Moonetix wall shows each user the offers available for their country and device, and blocks VPN, proxy, Tor and data center connections before they start an offer. Every offer is reviewed by the team before it goes live. Your reports break clicks, conversions and reversals down by country, offer and sub ID, and the traffic quality report shows how your users look to advertisers. Test on a normal home or mobile connection with “Open as a test user” from your app’s Integration tab. See how the wall works or get in touch.
Frequently asked questions
What is the difference between geo-targeting and geofencing?
Geo-targeting picks who sees an ad by country, region or city. Geofencing draws a small virtual boundary, such as a store or a stadium, and triggers an ad or message when a device enters it, usually using the device’s precise location.
How accurate is IP geolocation?
Country is usually correct on normal home and mobile connections. Region and city are less reliable, especially on mobile networks. Platforms such as Google Ads say plainly that location targeting is a best effort and not 100% accurate.
Why do offers pay more in some countries?
Advertisers pay what a user is worth to them. Users in higher-income countries tend to spend more, and more advertisers compete for them, so the same offer pays more there.
Can a VPN get me higher-paying offers?
No. Advertisers check the country at conversion, and results from hidden or faked locations are rejected. Most offerwalls, including Moonetix’s, block VPN and proxy users so they do not waste time on offers that would never pay.
Why do two users in the same country see different offers?
Offers also target devices and operating systems, and some have daily caps or are new-user only. An Android user and an iPhone user in the same city can see different lists.
Is geo-targeting legal under GDPR?
Yes, but the IP address it relies on can be personal data. You need a lawful basis, a clear privacy policy that mentions it, and you should avoid collecting more location detail than you need.
