International & multilingual SEO
Selling into more than one language or country changes the SEO problem entirely. Get your URL structure, hreflang tags and localisation right and each market reinforces the others; get them wrong and your own pages compete against each other. This guide walks through the decisions that matter.
International SEO covers two related but separate goals. Multilingual targeting serves the same content in different languages — English and French, say. Multi-regional targeting serves different countries that might share a language, such as US English and UK English. Many stores need both at once, and confusing them is where most projects go wrong. The site you are reading now is a working example of the multilingual case: every page exists in English under /en/ and French under /fr/, connected so Google serves each searcher the right one.
Choosing a URL structure
Before writing a line of translated copy, decide how the versions live at the URL level. There are three mainstream options, each a genuine trade-off:
- ccTLDs (example.fr, example.de) — the clearest geo-signal to users and search engines, but expensive to buy and maintain, and each domain builds authority from scratch
- Subdomains (fr.example.com) — flexible and can sit on separate servers, but authority does not always flow cleanly from the root domain
- Subfolders (example.com/fr/) — the version we use here; the whole site shares one domain's authority and it is the simplest to run, at the cost of a slightly weaker per-country signal
For most e-commerce brands starting out, subfolders on a single strong domain are the pragmatic default. ccTLDs make sense once a country is a real, standalone business priority with the resources to match. There is no universally correct answer — only the one that fits your scale and roadmap.
hreflang: telling Google who each page is for
Once you have parallel versions, hreflang annotations tell search engines which language and region each page targets, so the right one appears for the right searcher and the versions are not treated as duplicate content. The rules that trip people up most:
- Annotations must be reciprocal — if the English page points to the French page, the French page must point back, or Google ignores the set
- Every set should include a self-referential tag pointing to itself
- Use correct ISO codes: language (
en,fr) optionally plus region (en-gb,fr-ca) — never invent codes likeen-uk - Add an
x-defaultfor searchers who match no specific version
You can implement hreflang in the HTML <head>, in HTTP headers, or in the XML sitemap. Pick one method and apply it consistently; mixing them is a common source of errors. Because hreflang is a technical layer that has to stay in sync as the site grows, it belongs in the same discipline as the rest of your crawl and indexing setup — our technical SEO guide covers the foundations it sits on, and our technical SEO service handles implementation and validation when the matrix gets large.
Localisation, not translation
The single biggest content mistake in international SEO is treating it as a translation task. Running your pages through machine translation produces text that is grammatically passable and commercially flat. Real localisation adapts to how each market actually searches and buys:
- Keywords differ beyond translation — a British shopper searches trainers, an American sneakers; direct translation misses the demand entirely
- Currency, sizing, units, date formats and payment methods must match local expectations
- Tone, examples and cultural references need adapting, not just words
- Legal and shipping information has to reflect each region's reality
This is why we localise rather than translate our own EN and FR pages: each version is written for its reader, not mechanically converted from the other. Do your keyword research natively in each language before writing, because the terms real customers use rarely survive a literal swap.
Common failure modes
A few mistakes account for most lost traffic: broken or non-reciprocal hreflang that leaves Google guessing; auto-redirecting users by IP so crawlers only ever see one version; thin machine-translated pages that add no local value; and forgetting that each new market multiplies the technical surface you have to keep healthy. Start with one additional language or region, get the structure and hreflang genuinely right, measure per-market performance in Search Console's country and query filters, then expand. Watch each market's clicks and impressions separately rather than a single blended total, so a strong region does not mask a broken one. Disciplined and small beats broad and broken every time, and a clean two-language setup is a far better foundation to grow from than a sprawling one held together with guesswork.
