Subfolder, subdomain or country domain

International SEO 14 September 2026·10 min read

The most expensive decision in international SEO is usually made first, fastest, and by whoever set up the CMS. It is the only choice on an international audit that is genuinely hard to reverse, so it deserves an hour of thought before a single page is translated.

What Google’s documentation actually says

Google sets out four ways to structure a multi-regional site, with its own pros and cons for each. Here they are in Google’s words, from its guide to managing multi-regional and multilingual sites, last updated in December 2025:

StructureGoogle’s prosGoogle’s cons
Country-code domain
example.de		Clear geotargeting · Server location irrelevant · Easy separation of sitesExpensive (can have limited availability) · Requires more infrastructure · Strict ccTLD requirements (sometimes) · Can only target a single country
Subdomain
de.example.com		Easy to set up · Allows different server locations · Easy separation of sitesUsers might not recognize geotargeting from the URL alone
Subdirectory
example.com/de/		Easy to set up · Low maintenance (same host)Users might not recognize geotargeting from the URL alone · Single server location · Separation of sites harder
URL parameters
example.com?loc=de		None listedNot recommended · URL-based segmentation difficult · Users might not recognize geotargeting from the URL alone

Two things stand out. URL parameters are the only option Google explicitly does not recommend. And none of the trade-offs Google lists between subdomains and subdirectories is about ranking: they concern how clearly the URL signals a country, how much infrastructure you run, and how easily the sites can be separated.

What changed: there is no country setting any more

For years you could tell Search Console which country a subfolder or subdomain was aimed at. Google deprecated the International Targeting report in August 2022, explaining that country targeting in Search Console “was determined to have little value for the ecosystem.” Hreflang, it said, stays supported.

So the country signal now has to come from the site itself. Google lists what it uses: a country-code domain, hreflang, the server’s location, and other signals such as local addresses and phone numbers, local language and currency, and links from other local sites. It also lists what it does not use: it ignores locational meta tags such as geo.position, and it tells site owners not to use IP analysis to adapt their content.

The practical consequence: a country-code domain is the only structure that carries a country signal by itself. A subfolder or subdomain relies on hreflang and on-page signals to do that job — which they do perfectly well, when they are implemented correctly.

What the documentation leaves out

Google’s table is accurate and incomplete. It describes the structures. It does not describe the costs that decide which one a business can actually sustain.

Every new domain starts with no links

A new country domain has no referring domains on the day it launches. A subfolder on an established domain launches onto a link profile the business has spent years building. That difference appears in no comparison table, and it is the single biggest reason I recommend subfolders by default: the new market does not have to earn its authority from zero.

Everything multiplies

Five country domains means five domains to renew, five certificates, five Search Console properties, five analytics set-ups — and, the one that sinks budgets, five link-building programmes. Some registries add eligibility rules of their own, which is what Google’s “strict ccTLD requirements” refers to.

Subdomains usually mirror the org chart

When a site uses subdomains, the reason is rarely SEO. A different team, a different platform or a different agency runs that market, and a subdomain is the easiest way to let them. That can be a legitimate reason. It should be a conscious one.

Changing your mind is a migration

Moving from subdomains to subfolders later means redirecting every URL in every market, then absorbing the volatility that follows. That is why architecture comes first in my international SEO audit checklist — and why “it came with the CMS” is not an answer.

The decision, as I would make it

For most businesses selling into several markets, the answer is a subfolder. The exceptions are specific, and each one comes with a reason you can write down.

A decision diagram with four questions in order. If one language serves several countries with the same offer, use a language subfolder such as /es/. If prices, products or legal terms differ by country, use country subfolders such as /de/. If there is a local legal entity, a separate product line or an unusable brand name, consider a country-code domain. If a separate team or platform cannot share the main site, use a subdomain. URL parameters are marked as not recommended.
Work down the questions and stop at the first yes. Most sites stop at the first or second one.

  1. Same offer, one language, several countries → a language subfolder

    A single /es/ section can serve Spain, Mexico, Colombia and Argentina at once. This site does exactly that: one Spanish section and no country sites.

  2. Prices, products or legal terms differ by country → country subfolders

    /de/, /fr/, /es-mx/ — each declaring language and country in hreflang, on the domain that already has the links.

  3. A local legal entity, a genuinely separate product line, or a brand you cannot use there → consider a country domain

    Then budget for building that market’s authority from nothing. I set the bar in the same place in the note on entering the German market: a .de helps marginally with trust, and rarely justifies the cost on its own.

  4. A separate team or platform that cannot share the main site → a subdomain

    Accept the operational split knowingly, and implement hreflang across hosts as carefully as you would within one.

  5. URL parameters → no

    Google does not recommend them, and neither do I.

The mistakes I see most

  • Three structures at once. /de/ on the main domain, example.fr and uk.example.com — each chosen by a different project, none by a strategy.
  • Folders named after countries, filled by language. A folder called /uk/ for British English breaks nothing by itself, but it invites the matching mistake in hreflang, where uk means Ukrainian. My hreflang generator flags exactly that.
  • Redirecting visitors by IP. Google advises against adapting content based on IP analysis. Offer a visible way to switch market instead, and let crawlers reach every version.
  • Choosing country domains without funding them. The structure was chosen for the launch; the link building needed to make it work was never in the budget.

Questions

Google frames the choice around how clearly the URL signals a country, setup effort and maintenance — not ranking. The difference that matters most in practice: a new country domain starts with no links, while a subfolder launches on the link profile your domain already has. Hence subfolders by default.
No. A ccTLD is the only structure that signals a country on its own, but Google also uses hreflang, server location and local signals — addresses, currency, links from local sites. A country subfolder with correct hreflang competes perfectly well.
No. Google deprecated the International Targeting report in 2022, saying manual country targeting had little value for the ecosystem. The signal now has to come from hreflang, the domain and the page.
Google advises against adapting content based on IP analysis. Let visitors and crawlers reach every version, and give people a clear, crawlable way to switch market.
