What are Tier 1, Tier 2, and Tier 3 Countries?

In digital advertising, advertisers frequently rank countries into tiers, depending upon the potential of that country to produce ad conversions (which translate to customers, sales, and ultimately profits) for the advertiser's business. Countries with the highest business potential are given the rank of Tier 1. Most advertisers recognize three tiers of countries: Tier 1, Tier 2, and Tier 3. However, some advertisers may utilize a fourth tier to add further granularity to their rankings.

Country tiers are both subjective and impermanent. Each source (typically marketing firms) has its own list of countries and tiers, and while these lists tend to follow the same general trends, differences between lists are also quite common. A country classified as Tier 1 by one source may be considered Tier 2 or Tier 3 by another source. Countries may also move up or down the tiers (either permanently or temporarily) depending upon political and economic developments including (but not limited to) wars, civil unrest, or trade embargoes.

Online Advertising Tiers Explained:

Tier 1

In most cases, Tier 1 countries produce the most sought-after type of traffic, which makes them the highest-priority targets for advertisers. Tier 1 countries tend to be among the world's wealthiest countries, with healthy, highly developed, mature economies resulting in a high national income and a high GNI per capita. As a result, the residents of Tier 1 countries earn high average salaries and possess ample disposable income. This gives them what some marketers call "high acquisitional power" and makes them ideal potential customers to advertisers.

The number of high-income residents in a country—and the language they speak—is also important. Countries such as Monaco and Liechtenstein rank among the wealthiest countries in Eruope and the world in terms of income per capita. However, they also have two of the world's smallest populations and their primary languages are French and German respectively. As such, an English-speaking advertiser may find few potential customers in these countries and therefore classify them as Tier 2 or Tier 3 instead of Tier 1.

Tier 1 countries also come with unique business challenges. Tier 1 countries tend to be highly competitive business markets, so the field of rival advertisers may be more crowded. The competition in Tier 1 countries also gives them a higher cost per click (CPC)—a term used to describe the cost to the advertiser of acquiring a user interaction, which is typically initiated by the user "clicking" on an online ad—than countries in other tiers. Tier 1 countries may also have stricter advertising guidelines to navigate.

Tier 2

Tier 2 countries have high- or middle-income economies that are either smaller or less wealthy than those of Tier 1 countries, but which are still either already healthy and mature or developing in the right direction, and so have strong potential for business. The residents of Tier 2 countries may have less disposable income on average, so profit margins may be lower and there will be fewer customers with both true intent and the legitimate wherewithal to do business. Customers are also less likely to speak English, so advertisers whose primary markets are English-speaking may need to budget for translation services.

On the other hand, the markets in Tier 2 countries usually have reduced competition and less-demanding consumers, which makes potential customers easier to convert into paying customers. Tier 2 countries tend to have fewer advertising regulations, and overall cost-per-click (CPC) for online advertising is lower than in Tier 1 countries, so advertisers can implement ad campaigns more easily and affordably.

Tier 3

The vast majority of Tier 3 countries are low-income and developing (or least-developed)countries whose economies are weaker, but can still provide significant opportunities for the right product in the right marketer's hands. Residents of Tier 3 countries tend to have low salaries and little disposable income. As a result, fewer products will be a good fit for the market, and connecting with potential customers may require more knowledge of the specific national culture and market than would be needed in Tier 1 or Tier 2 countries. Customer conversion rates and the profits from those conversions may be dauntingly low. However, Tier 3 countries also have the most affordable ad rates, the fewest advertising restrictions, and the lowest likelihood of competitions in the market.

Tier 4

A very rarely used tier. While most marketers utilize a three-tiered system in which any country that is not Tier 1 or 2 automatically falls into a catch-all Tier 3, some marketers add this fourth tier. Tier 4 countries are usually those whose economies have completely collapsed due to political strife or severe financial mismanagement, or which are under international sanctions that restrict the business opportunities with those countries.

Profiles of Common Tier 1 Countries

Australia

With more than 26 million residents as of 2023, Australia is the most populous country in Oceania and the 55th-most populous country in the world. However, it consistently ranks in the top 15 for Gross Domestic Product (GDP) and median annual income, indicators of Australia's higher-than-average wealth. Although Australia has one of the lowest population densities of any country in the world, it nonetheless has five cities with over a million people: Sydney (the most populous), Melbourne, Canberra, Brisbane, Perth, & Adelaide. Like most Tier 1 countries, Australia scores quite high on the Human Development Index as well.
