Subdirectory vs Subdomain vs ccTLD: Choosing Your Multilingual URL Structure

Before translating a word, you choose where languages live: example.com/fr/ (subdirectory), fr.example.com (subdomain) or example.fr (ccTLD). The choice shapes SEO, infrastructure and maintenance for years.

Subdirectories: the 90% answer

Every backlink you have ever earned boosts every language. One SSL, one host, one analytics property, trivial caching. Google’s own documentation leans this way for most sites. This is what Transxlate implements out of the box (details).

When subdomains make sense

Genuinely separate infrastructure per market (different hosting regions, different teams with deploy access) — rare for SMBs. The SEO cost of split authority is real and permanent.

When ccTLDs earn their cost

Major consumer brands in markets with strong local-domain trust (Germany, France, Japan) and the budget to build per-domain authority. Below that scale, region-targeted hreflang on subdirectories (fr-ca on /fr-ca/ paths) captures most of the benefit at none of the cost. See market-specific guidance in our country guides.
