At the advertising cost level, the difference between GEOs looks obvious. Tier-1 requires a higher traffic acquisition budget, while in Tier-3 the same amount can generate significantly more impressions and clicks.

For traffic arbitrage and performance marketing, this comparison is not enough. The final result also depends on conversion, audience quality, local payment infrastructure, regulation, LTV, and another critical metric — average deposit, or how much a user acquired through a specific traffic source deposits on average.

That is why Tier should be treated as an initial characteristic of a market. The real answer comes from the unit economics of a specific product.

Traffic costs can differ several times over

The scale of the difference is easiest to see through CPM.

According to one public Meta Ads benchmark for 2026, average CPM in the US is estimated at around $16.08, in the UK at $11.81, and in Germany at $9.05. For Brazil, the estimate is around $2.63, and for the Philippines $3.40.

These are third-party benchmarks, and actual costs depend on audience, competition, format, seasonality, and the parameters of a specific campaign.

Still, the difference clearly shows how GEO affects media buying: the same budget can provide very different levels of potential audience exposure.

In more expensive GEOs, businesses pay more for access to users but may reach audiences with greater purchasing power. In lower-cost GEOs, the same budget allows teams to work with significantly higher volumes.

This is where CPM alone stops being enough.

CPA matters, but average deposit tells you much more

Imagine that acquiring a depositor costs $100 in one GEO and $30 in another.

At first glance, the second option looks significantly more attractive.

But the next question is: how much does that user actually deposit on average?

If the average deposit in the first GEO is, hypothetically, $150–200, while in the second it is $20–30, the difference in CPA suddenly looks very different.

That is why average deposit is one of the key metrics we look at after CPA.

It helps estimate the actual value of traffic before enough data has accumulated for a full LTV analysis.

It is especially useful when viewed together with FTD volume, repeat deposits, and retention.

In a highly simplified form, the economics look like this:

result = value of deposits and future player value − acquisition costs − operational costs.

A lower CPA does not automatically mean better traffic.

In media buying, it is important to understand how many users reach the deposit stage, how much they deposit, and what happens to them afterwards.

One GEO can deliver volume, another higher player value

This is where Tier-1 and Tier-3 start to operate as different economic models.

Tier-1 usually comes with a higher entry cost. CPM and CPA are higher, but average deposit can also be higher due to greater purchasing power.

Tier-3 makes it possible to acquire much more traffic with the same budget. At the same time, the average deposit per user may be lower, so profitability depends more heavily on scale, conversion, and repeat deposits.

In simplified terms:

Tier-1: fewer users → higher acquisition cost → potentially higher deposit per player.

Tier-3: more users → lower acquisition cost → potentially lower deposit per player, compensated by volume.

This is why asking “Where is CPA cheaper?” often gives only part of the picture.

A more useful question is:

how much deposit value does every dollar spent on acquisition generate?

Traffic quality should also be evaluated separately

Tier is often used as a quick benchmark for evaluating a market. It is not enough to assess the quality of a specific traffic source.

Fraud, invalid traffic, and low-quality audiences can appear across different markets. Results also depend on the channel, platform, buying model, partner, and traffic validation system.

That is why after CPM and CPA, we look deeper:

how many users reach FTD, what their average deposit is, whether they come back for a second or third deposit, and how they behave after a week or a month.

This layer of data shows how well a specific traffic source actually works for the product.

Regulation also changes GEO economics

Another important factor is the local regulatory environment.

In regulated digital industries, operating conditions can vary significantly between countries. Licensing, advertising requirements, payments, and user verification all directly affect the business model.

As a result, two GEOs with similar traffic costs can have very different actual economics.

Brazil is a good example of this shift. In terms of advertising costs, it remains significantly cheaper than the US or the UK, while its regulatory environment and payment infrastructure are becoming more mature.

This makes a rigid Tier-1, Tier-2, and Tier-3 classification increasingly less informative on its own.

What we look at before launching a GEO

For a proper market assessment, Tier alone is not enough.

In digital marketing, we look at a wider set of metrics:

• CPM and actual acquisition cost;

• CPA and FTD volume;

• average deposit;

• repeat deposits;

• conversion across key funnel stages;

• approval rate;

• traffic quality;

• retention and LTV;

• local payment infrastructure;

• regulatory and operational restrictions.

Together, these metrics show the actual economics of a GEO.

So which GEO is more profitable?

There is no single answer for the entire market.

Tier-1 usually means more expensive access to an audience with greater purchasing power and potentially a higher average deposit.

Tier-3 and other volume GEOs can deliver more traffic for the same budget, but average deposit, repeat deposits, and overall user quality become especially important.

At Toba Traffic, the decision depends on the client’s specific objective.

If the priority is scale and faster volume, we may focus on volume GEOs. If the product economics allow for higher acquisition costs in exchange for greater player value, high-value GEOs may make more sense.

In many cases, the most resilient model is a combination of several markets with different economics.
