What Is International SEO?

International SEO is the work of making a site serve the right language and regional version to the right audience.

In plain English

Two decisions come first: which languages and regions you are genuinely serving, and how the URLs will be structured. Everything else follows from those.

The most common failure is not technical. It is translating a site without localising it, so the words change but the currency, examples, objections and search behaviour do not.

What to know

Structure
Country domains, subdirectories or subdomains. Subdirectories are usually the pragmatic choice.
hreflang
Annotations telling search engines which version serves which language and region, reciprocally.
Localisation
Currency, units, spelling, examples, contact details and the questions that market actually asks.
Research per market
Keyword research repeated locally. Direct translations of keywords are frequently wrong.

Why it matters

Done properly this multiplies an existing content investment across markets. Done carelessly it creates duplicate pages competing with each other and a set of translated pages that rank in no market at all.

Common mistakes

×Machine-translating content and publishing it unreviewed.
×Broken or non-reciprocal hreflang annotations.
×Assuming a keyword translates directly into the same search behaviour.
×Launching six languages when one market has not been proven yet.

FAQs

Subdirectories or country domains?

Subdirectories inherit site authority and are cheaper to run. Country domains signal locality more strongly and cost more to maintain.

Do I need hreflang for the same language in two countries?

Yes, if the content differs. It is how the right version reaches the right region.
