The same offer makes a profit in one country and burns the budget in the next. Click price, payout, approval rate, creative language, laws — it all depends on the GEO. Here's a plain-language guide to what a GEO is in affiliate marketing, how Tier-1, Tier-2 and Tier-3 differ, and how to pick a country for a specific offer instead of guessing.
What a GEO is in affiliate marketing
A GEO (short for geography) is the country or region where the users you send traffic to live. Every offer lists its GEOs: the network only pays for conversions from allowed countries. If an offer is open for Germany, a lead from Austria won't count.
The GEO is one of the building blocks of a bundle, along with the offer, traffic source, creative and landing page. Change the country and you've essentially built a new bundle: a different audience, a different auction, different money.
Russian-speaking affiliates also split GEOs into "burzh" — foreign markets, usually Europe, the US, Asia and LatAm — and the CIS. But for choosing a country, the tier split matters more.
Tier-1, Tier-2, Tier-3: what they are
Tiers group countries by audience purchasing power and traffic cost. There's no official list: one network puts Poland in Tier-2, another in Tier-1; some consider Indonesia Tier-2, others Tier-3. Treat tiers as a guideline, not a law.

- Tier-1 — wealthy countries with expensive traffic: the US, Canada, the UK, Australia, New Zealand, Germany, France, the Netherlands, Switzerland, Austria, Ireland and the Nordics. The UAE, Saudi Arabia and Japan are often added for their purchasing power.
- Tier-2 — the middle level: Poland, Czechia, Spain, Italy, Portugal, Brazil, Mexico, Chile, Argentina, Turkey, South Africa, Malaysia, Thailand, Kazakhstan.
- Tier-3 — cheap traffic and huge volumes: India, Indonesia, the Philippines, Vietnam, Pakistan, Bangladesh, Egypt, Nigeria, Kenya and most of Africa.
How tiers differ in practice

Traffic cost. This is the main difference. According to public 2026 benchmarks (Stackmatix, Adligator), Facebook CPM is roughly $10–21 in the US, $8–12 in Germany, $2–5 in Brazil and Mexico, and $1–2 in India. The gap between the most and least expensive countries is 10–15x. Figures differ between providers, and they don't disclose their methodology, so treat them as a guideline, not a price list.
Payouts. The richer the GEO, the more the advertiser pays per conversion. A deposit in Tier-1 can be worth several times more than in Tier-3, because a player or customer there brings in more money.
Competition. Big teams with big budgets run Tier-1, so the auction is tough. Tier-3 is easier to enter, but popular verticals there are long taken too.
Quality bar. Tier-1 audiences are used to ads: you need native language, quality creatives and landing pages, and the right local details. Machine translation shows immediately. The bar is lower in Tier-2 and Tier-3, but localization still lifts conversion.
Regulation and moderation. Wealthy countries have stricter laws on advertising, data protection and gambling, and platforms moderate ads for these GEOs more strictly.
A cheap click isn't a profitable one
The most common beginner mistake is choosing a GEO by the lowest click price. Cheap clicks won't help if the payout is small and the approval rate is low. What matters isn't CPM or CPC but EPC (earnings per click) and final ROI. The formulas are covered in our article on affiliate math.

In the illustrative example above, the budget is the same — $300. Tier-3 brings 15 times more clicks, but conversion and payout are so low that the campaign loses money. Tier-1 brings few clicks, but each conversion pays for them. The numbers are made up for illustration: in a real bundle it may turn out the other way round. That's why only testing and the math decide, not a tier's reputation.
Which verticals work in which GEOs
There are no strict rules, but each vertical has typical GEOs. It's a good starting point so you don't test the whole world. To compare verticals by earnings per click, see our vertical ranking by EPC.

- Gambling and betting. High payouts in Tier-1, big volumes in Tier-2 — Latin America and parts of Europe. Each country has its own online casino licensing rules: run only offers that are allowed in that GEO. More in our gambling vertical guide.
- Nutra. Often Tier-2 and Tier-3: Europe, LatAm, Asia. Many offers use cash on delivery (COD), so call-center approval and purchase rate matter. See how it looks in numbers in our nutra case study.
- Dating. The best SOI and DOI payouts are in Tier-1, but Tier-2 gives stable volume. Payouts by country are covered in our dating offers article.
- Finance, loans, credit cards. Heavily dependent on the local market and laws. Each offer is tied to a specific country and its financial products.
- Sweepstakes. More often Tier-1 and Tier-2 with mobile traffic. More in our sweepstakes article.
- Apps and utilities (CPI). Tier-3 gives huge install volumes at a low price; Tier-1 gives expensive but paying installs.
How to choose a GEO for an offer: step by step

- Start with the offer, not the country. Check which GEOs it's open for and the payout, approval rate, hold and KPIs in each. Payouts for one offer often differ several times between countries.
- Ask your network manager. They see stats across all publishers and know which GEOs convert right now. It's free and saves weeks of testing. If you haven't picked a network yet, here's how to choose one.
- Match the GEO to your budget. Testing Tier-1 takes noticeably more money to gather enough data. With a small budget, Tier-2 is a more sensible start.
- Check language and localization. Can you make a creative and landing page in the audience's native language, with local currency, names and details? AI helps, but have a native speaker check the final copy. More on creatives in our creatives guide.
- Check the laws and platform rules. Is the vertical legal in the country, and can it be advertised on your traffic source? For gambling, finance and crypto, this step is mandatory.
- See what competitors run. Spy tools show which creatives and angles have been running in the GEO for a long time. Long-running ads are a good sign the GEO works.
- Account for seasonality and timing. Holidays, paydays, sports events and time zones noticeably affect conversion.
- Test 2–3 GEOs in parallel. Don't bet everything on one country. Same budget, same conditions; after a few days, compare EPC and ROI in your tracker and keep the best.
Common mistakes when choosing a GEO
- Chasing Tier-1 with a small budget. The money runs out before you have enough data to draw conclusions.
- Choosing by click price. Cheap traffic with a low payout and approval rate is often worse than expensive traffic.
- Machine-translating creatives. In Tier-1, it immediately hurts trust and CTR.
- Ignoring the law. An offer banned in the country risks an ad account ban and rejected conversions.
- Mixing GEOs in one campaign. Without a per-country split, you won't see which one drags results down.
- Not viewing the landing page as a local user. Check how the page loads and looks from the target country: speed, currency, language. Proxies for that GEO help here.
FAQ
What is a GEO in affiliate marketing?
It's the country or region of the audience you send traffic to. The GEO is listed in the offer, and the network only pays for conversions from allowed countries.
Which countries are Tier-1?
Usually the US, Canada, the UK, Australia, New Zealand, Germany, France, the Netherlands, Switzerland, Austria, Ireland and the Nordics. The UAE, Saudi Arabia and Japan are often added. Each network has its own exact list.
Which GEO should a beginner start with?
Tier-2 is often a sensible start: traffic is cheaper than in Tier-1, and payouts are noticeably higher than in Tier-3. But the offer, your budget and the language you can make a quality creative in decide in the end. For a step-by-step start, see affiliate marketing from scratch.
What does "burzh" mean?
It's Russian-speaking affiliate slang for foreign GEOs: Europe, the US, Asia, Latin America. It's contrasted with the CIS.
Why does one offer convert in one country and not in another?
Purchasing power, habits and trust in ads, language and localization quality, auction competition, laws and even popular payment methods all play a role. That's why every new GEO is a new test.
