SEO for SaaS: how to choose which country to target first (with real data)

You have a SaaS. You know you should do international SEO. There are 195 countries in the world, and you have to pick one.

So you pick the US.

Everyone picks the US.

49,500 monthly searches for "SEO tool" in the US alone. The logic feels airtight. Go where the volume is.

This is usually a mistake, and we have the data to prove it.

The number most SaaS founders look at (and why it's not enough)

Search volume is the first thing everyone checks. It's also the least useful number on its own.

Here's what happens when you look at "SEO tool" across 10 countries simultaneously, using real DataForSEO data:

The US has the most searches. It also has a keyword difficulty of 65, meaning the first page of Google is owned by Ahrefs, Semrush, and Moz, all with domain authority built over a decade. A new SaaS competing there is not doing SEO. It's doing hope.

Now look at Japan. 390 searches. Keyword difficulty of 36. CPC of $8.78, almost as high as the US, which means Japanese searchers have real commercial intent. The organic competition is a fraction of what it is in English-speaking markets. And yet almost every SaaS founder ignores Japan because the volume number looks small.

This is the trap: volume tells you how many people are searching. It tells you nothing about whether you can actually reach them.

The three numbers that actually matter

Good international market selection requires three data points, not one.

Search volume tells you if there's demand. You need a minimum threshold: a market with 50 searches a month is probably not worth the investment regardless of difficulty.

Keyword difficulty (KD) tells you how hard it is to rank organically. It's scored 0 to 100. Below 40 is generally achievable for a new domain within 6 to 12 months with good content. Above 70 means you're fighting established players with thousands of backlinks.

CPC tells you what the market is worth. When advertisers pay $17 per click, they're converting those clicks into revenue. A high CPC with low KD is the rarest and most valuable combination in SEO: it means the market has money and nobody has dominated it organically yet.

Put them together and the picture changes completely.

What the data actually says about these 10 markets

Australia is the classic trap. KD of 87, the highest in this dataset, with only 1,000 monthly searches. Advertisers are paying $17.89 per click, which means someone is making money there. But organically, it's the hardest market to crack of the ten. A new SaaS with a low domain authority has essentially no chance of ranking for competitive terms in AU without years of link building.

Brazil looks attractive until you check the CPC. KD of 77, second hardest, but CPC of only $2. That's the worst combination: hard to rank for and low commercial value per visitor. The SEO effort required would far exceed the revenue potential for most SaaS products.

France and Poland are quietly interesting. Both have KD of 39, the lowest in the dataset. France has 880 monthly searches with a $6.88 CPC. Poland has 720 searches and a $5.43 CPC. Neither will make you rich, but both are genuinely achievable markets for a new domain. If your product works in French or Polish, these are markets where you can actually rank within a reasonable timeframe.

Japan is the most overlooked opportunity. KD of 36 with a CPC nearly as high as Canada ($8.78). The combination of low organic competition and high commercial intent is rare. The barrier? Content needs to be in Japanese to capture the full market. But for SaaS founders willing to invest in localization, Japan consistently underperforms its potential in most international SEO strategies.

The US remains valid with the right conditions. If your domain already has authority, if you can produce content consistently for 18+ months, and if you have the budget to build backlinks, the US volume justifies the effort. But for most early-stage SaaS products, it's the last market to enter organically, not the first.

A simple framework for making the decision

Before picking a market, run each candidate through three questions:

1. Can you realistically rank there?

If your domain is new or has low authority, focus on markets with KD below 50. That rules out AU, BR, DE, and US for most early-stage products.

2. Is there enough volume to matter?

Set your floor based on your conversion rate and target. If you convert 2% of organic visitors and need 10 trials a month to grow, you need at least 500 monthly searches for your core keyword. That filters out the lowest-volume markets.

3. Does the CPC signal real commercial intent?

A market where nobody is paying for clicks is a market where conversion is uncertain. CPC above $5 is a reasonable signal that searchers have commercial intent.

Apply those three filters to the table above and a clearer picture emerges:

The mistake hiding in plain sight

Every analysis above used a single keyword: "SEO tool."

Your SaaS has different keywords. And those keywords behave completely differently across countries. A keyword that's brutally competitive in the US might have KD of 25 in Germany. A market that looks small by volume might have three times the CPC of a larger one.

This is the actual problem with international SEO for SaaS founders: the analysis needs to happen at the keyword level, across multiple countries, before you commit to a market. Most founders skip this step because it's tedious to do manually. You'd need to run dozens of queries across 10+ countries, normalize the data, and build a decision framework from scratch.

That's exactly what Rankship does. You connect it to your AI assistant, Claude, Cursor, or Windsurf, point it at your product's URL, and ask: "which market should I target first?" It pulls real keyword data across 172 countries, applies the same logic described in this article, and gives you a ranked list of opportunities specific to your product.

The answer won't always be the country with the most searches. It almost never is.
