Which countries are Tier 1 countries?

Usually wealthy countries with high purchasing power and mature e-commerce: the United States, Canada, the United Kingdom, Australia, New Zealand and the countries of Western and Northern Europe. Each network and ad platform keeps its own list, and there is no single standard.

What does tier 1 traffic mean?

It is traffic from Tier 1 countries: audiences with high purchasing power, expensive clicks and high offer payouts. Affiliates often contrast it with cheaper Tier 2 and Tier 3 traffic, where clicks cost less but payouts and approval rates are lower too.

Which GEO should a beginner choose?

One where you understand the language and culture and where a mistake is cheap. That is often a Tier 2 or Tier 3 country: traffic is cheaper, so testing costs less. Payouts are lower there as well, so you still have to run the numbers carefully.

Why is Tier 3 traffic cheap but not always profitable?

Because it is not only the click price that is lower, but also the payout and often the approval rate. Cheaper GEOs also have more mobile traffic on slow connections and budget devices, so a funnel that works in Tier 1 may not convert there without adaptation.

Can I target several GEOs in one campaign?

Yes, if the countries are close in language, prices and payout. But look at the stats for each country separately: in the total, a profitable GEO can hide a losing one.

Tier 1, Tier 2, Tier 3 Countries in Affiliate Marketing

The same funnel can make money in one country and bleed money in the next one over. The reason is not the creative and not the offer but the GEO: every country has its own traffic cost, its own payout, its own approval rate and its own audience. Grouping countries into Tier 1, Tier 2 and Tier 3 is the quickest way to get your bearings, which is why choosing a GEO is one of the first decisions a media buyer makes, and it deserves to be made deliberately.

What is a GEO in affiliate marketing

A GEO (short for geography) is the country or region whose audience an ad campaign targets and where the offer is valid. Offers in CPA networks are almost always tied to GEOs: the product is sold in specific countries, the call center speaks specific languages, and the payout is listed per country.

For a media buyer, the GEO determines:

the payout per lead or sale;
the traffic cost — per click or per thousand impressions;
the approval rate — the share of leads the advertiser confirms;
the language of creatives and landing pages;
the rules — from the ad platform's policies to the country's laws on advertising certain categories;
the timing — the audience's time zone and the advertiser's call center hours.

Country tiers: Tier 1, Tier 2, Tier 3

So you do not have to keep two hundred countries in your head, they are loosely grouped into tiers. The split is informal: lists differ between affiliate networks and ad platforms. The main criterion is the audience's purchasing power and, as a result, what advertising costs.

Tier	Typical countries	Traffic cost	Payouts	What to expect
Tier 1	USA, Canada, UK, Australia, New Zealand, Western and Northern Europe	High	High	Fierce competition, strict ad policies and laws
Tier 2	Parts of Eastern and Southern Europe, the larger Latin American countries, parts of Asia and the Middle East	Medium	Medium	Balance of price and volume, many languages
Tier 3	Many countries in South and Southeast Asia, Africa, parts of Latin America	Low	Low	Big volumes, lots of mobile traffic, lower approval

Russian-speaking affiliates also single out the CIS (former Soviet countries) as a separate group; by traffic cost and payouts it sits closer to Tier 2 and Tier 3.

Tip. Do not go by the tier label alone. Countries within one tier differ a lot in approval rate, competition and rules. Check the payout and the offer's stats for the specific country with your affiliate manager.

Tier 1 countries: expensive but high-paying

Tier 1 is the premium end of the market. Purchasing power is the highest, payment systems are mature, and people are used to buying online. Offer payouts are high, but so is traffic cost, and competition for the audience is at its peak: you are in the same auction as big brands with big budgets.

For a media buyer this means:

testing costs more and mistakes hurt more;
creatives and landing pages have to be better;
advertising in finance, gambling, health and other sensitive categories is more tightly regulated — see the article on restricted ad categories;
on the upside, the profit on a single lead can be several times higher than in cheap GEOs.

Tier 2 countries: the middle ground

Tier 2 is often chosen for scaling: traffic is cheaper than in Tier 1, payouts are still decent, and competition is softer. The difficulty is diversity: languages, mindset and payment habits vary a lot from country to country, and a creative that works in one may flop next door.

Tier 3 countries: volume and a low entry barrier

Tier 3 GEOs have cheap traffic and big volumes. They are a good place to learn and test hypotheses: mistakes are cheap. But the margins are thin: payouts are low, approval is often lower, and a large share of visitors are on mobile devices with unstable connections. A heavy landing page loses a noticeable part of the audience before the first screen even loads.

How to choose a GEO for a test

Choosing a GEO is a calculation, not a trend. Run through this checklist.

Is there an offer with a good payout and approval rate in this GEO? Look at the offer page and ask the network manager. How to work with networks is covered in the article on CPA networks.
What does traffic cost on your chosen source? Check the forecast in the ad platform.
Do the numbers add up? Your break-even click price equals EPC: CR × payout × approval rate. How to calculate it is explained in the article on affiliate marketing metrics.
Do you understand the language and culture? A creative in a language you do not know risks mistakes in meaning.
What do the platform's policies and the country's laws say? Some ad categories need a license in certain countries or are banned outright. Follow the platform's rules — for example, the Google Ads advertising policies.
What test budget can you afford? In Tier 1 it will be higher. More on this in the article about budgets and bids.

A worked example for illustration

Say an offer runs in two GEOs. In country A the payout is $40, the expected click-to-lead CR is 2%, and approval is 50%. EPC = 0.02 × 40 × 0.5 = $0.40. In country B the payout is $12, CR is 3%, and approval is 40%. EPC = 0.03 × 12 × 0.4 = $0.144.

If a click costs $0.50 in country A and $0.08 in country B, then despite the high payout the campaign loses money in country A and is profitable in country B. What decides it is neither the payout nor the click price on its own, but the ratio between them.

Localization: what to adapt for a GEO

Moving a funnel to a new GEO is more than changing the country in targeting.

Language — the creative, pre-lander and landing page in the audience's language, with local phrasing rather than machine translation.
Currency and prices — in local currency and the familiar format.
Visuals — people, places and situations the audience recognizes.
Timing — show ads when the audience is active and the call center can call back.
Devices — in mobile-heavy GEOs the landing page has to load fast on budget smartphones.

GEO and traffic quality

Platform targeting does not guarantee that only people from the right country land on your page. Some clicks come through VPNs and proxies, others from bots and review tools running in data centers in other countries. If you do not check the GEO on your side, your country stats get distorted and the offer receives leads the advertiser will reject. How VPNs, proxies and hosting IPs are detected is covered in the article on VPNs, proxies and data centers.

Another signal is a mismatch between the IP country, the browser language and the device time zone. Each of these mismatches on its own happens to real people too (travelers, expats), so they should be weighed together with other signals. More in the article on filtering by GEO, language, device and schedule.

Working with GEOs in ArtisanClo

In ArtisanClo the GEO plays a part in both filtering and reporting.

Audience rules in the flow settings — lists of countries, languages, time zones, cities and regions with Allow and Block modes. A visitor who fails a list sees the White Page with a clear reason, such as «Country not allowed». An empty list restricts nothing.
Campaign schedule (from the Professional plan) runs in the campaign's time zone, not the visitor's: handy if the offer only accepts leads during the call center's working hours.
Branches (from the Professional plan, in the modes with a tracker) send visitors from different countries to different offers through one ad link: one country to an offer with a local payout, another to a different one.
Statistics break traffic down by GEO alongside devices, OS, browsers and providers, and Reports show the money by country: clicks, conversions, CR, revenue, cost, profit and ROI. In the report builder you can build a tree such as «offer → country».

This way you see not only which GEO makes money but also what share of each country's traffic was filtered out as bots and reviews. More on the features page and in the traffic source catalog.

How to test a new GEO

A new GEO is a new funnel, even if the offer and the creative stay the same. So test it like a new funnel.

Start with one country. Do not launch five GEOs at once: the budget gets spread thin and no country collects enough data.
Localize the essentials. Creative and landing page language, currency, recognizable visuals. Do the full adaptation once the GEO shows promise.
Set the budget in this GEO's payouts. A limit of a few payouts will be a different dollar figure for Tier 3 and Tier 1 — that is normal.
Track the country in your labels. If a campaign covers several countries, the country has to show up as a separate slice in reports.
Wait for approvals. Advertisers in different GEOs confirm leads at different speeds and rates.
Compare by EPC and profit, not by lead count.

A country comparison for illustration

Say a funnel runs in three neighboring countries that share a language. After a week the country report shows: the first country makes a steady profit, the second is around break-even, and the third is in the red, even though it brought more leads than the first. Digging in shows the third country has a low approval rate: the advertiser cannot reach some of the customers by phone. The fix is to turn the third country off or ask the network manager for a different offer there, and keep the second one for creative work.

In the total, this campaign would have looked like a small profit. The split by country showed exactly where the money was leaking.

GEO and ad scheduling

For offers confirmed by phone, timing matters a lot. A lead submitted at night local time often waits until morning for a call, and by then the person may have changed their mind. If a campaign covers countries in different time zones, a schedule set to one zone will be wrong for part of the audience. Split such countries into separate campaigns or set up a schedule for each.

Common GEO mistakes

Going into Tier 1 without the budget. An expensive test gets cut before the funnel has a chance to show results.
Assuming cheap traffic is good value. A low click price with a low EPC is just as much of a loss.
Looking at the total across all GEOs. A profitable country masks a losing one. Break reports down by country.
Translating creatives word for word. The audience instantly feels a foreign voice.
Ignoring local rules. What is allowed in one country may be banned in another.

Bottom line

A GEO in affiliate marketing is not just a line in your targeting settings; it is the foundation of the funnel's economics. The Tier 1, Tier 2 and Tier 3 split helps you get oriented fast, but the decision rests on the numbers for a specific country: payout, approval rate, traffic cost and EPC. Pick GEOs where the economics work and where you understand the audience, follow the platform's policies and local laws, and read your reports country by country.
