International Site Structure
International site structure is the way a website organises its versions for different countries or languages, usually using separate country domains, subdomains or subfolders. The choice affects how authority is shared, how easy the site is to manage and how clearly search engines understand which market each page serves.
The main options
| Structure | Example | Summary |
|---|---|---|
| ccTLDs | example.de | Strongest country signal, but authority is split across domains. |
| Subdomains | de.example.com | Easy to host separately, but may be treated more like separate sites. |
| Subfolders | example.com/de/ | Keeps authority on one domain and is simplest to maintain. |
| URL parameters | example.com?lang=de | Not recommended by Google for language or country versions. |
Choosing between them
- ccTLDs suit large brands with local teams, budgets and offline presence in each market. A ccTLD tells users and search engines exactly which country you serve.
- Subfolders suit most small and mid-sized businesses. Links earned anywhere benefit the whole domain, and one CMS can run everything.
- Subdomains sit in between. They can make sense when different teams or platforms run each market. The wider subdomain vs subfolder debate applies here too.
Google has said that it can handle all three structures, so the right choice depends on resources and business goals as much as rankings.
Whether to organise by language or country
Decide whether you are targeting languages, countries or both. A Spanish-language section might serve Spain and Latin America together, while separate /es-es/ and /es-mx/ sections allow different prices, products and wording. Only split by country when there is a real difference in what you offer. This decision links closely to multilingual SEO.
How to implement an international structure
- List your target markets and languages, based on demand and your ability to serve them.
- Pick one structure and apply it consistently across the site.
- Use hreflang to connect equivalent pages, including an x-default fallback where useful.
- Give each version its own crawlable URLs, rather than swapping content with cookies or scripts on a single URL.
- Link between versions with a visible language or country switcher.
- Localise content, prices and contact details instead of copying pages.
- Track each version separately in Search Console and analytics.
Why structure matters for SEO
Structure decides how easily search engines can crawl each version, how authority built in one market helps another, and how much work every new country adds. A clear setup makes reporting simpler too: you can filter Search Console by folder, subdomain or domain and see exactly how each market is doing. Getting it right early is far cheaper than changing it after launch.
Common mistakes
- Mixing structures, such as some countries on ccTLDs and others in subfolders, without a clear reason.
- Automatically redirecting users by IP address, which can stop search engines seeing every version.
- Showing different languages on the same URL depending on browser settings.
- Switching structures later without a full website migration plan and redirects.
