A multilingual website in Brussels: building FR, NL and EN versions that actually rank
An automatic translation button is not enough. URL structure, hreflang, per-language content and the common traps to being found in all three languages.

01
Why automatic translation does not rank
A module that translates the page on the fly in the browser creates no Dutch page: Google sees only one version, in the original language. Dutch-speaking customers searching in their language do not find you.
To be found in three languages you need three sets of pages, each with its own address, title, description and content.
02
Choosing the URL structure
Three options: a directory per language on the same domain, a subdomain per language, or a domain per language. For a Brussels business the directory is the simplest and concentrates authority on a single domain.
Translate the addresses themselves too: a Dutch page at a French address loses the keyword in the language people search in, and looks unfinished.
Three options: a directory per language on the same domain, a subdomain per language, or a domain per language.
03
Linking versions with hreflang
Each page must declare its equivalents in the other languages through hreflang tags, including itself. That is what lets Google show the right version for the user’s language, and stops the versions competing with each other.
One markup error on a single page is enough to break the group. Test with Search Console after every page you add.
04
Translate or adapt
A literal translation of marketing copy reads badly. Adapt examples, local references and phrasing. Brussels Dutch is not a Netherlands translator’s Dutch, and English often targets expats, who have their own questions.
Decide who will maintain the three versions. A language left six months behind signals a neglected site, in that language precisely.
05
Common traps
Automatic redirection based on browser language, which stops Google crawling the other versions and frustrates users. A language switcher that sends to the home page instead of the equivalent page. Forms and confirmation e-mails left in one language.
Remember legal notices, terms and the privacy policy: they must exist in every language offered.

Frequently asked questions
- Do I really need English?
- In Brussels, often yes: institutions, expats and international companies search in English. Elsewhere in Belgium it depends on your clientele.
- Can I launch one language at a time?
- Yes, provided the structure is planned from the start. Adding a language later is simple if addresses and tags were designed for it.
- Is AI translation acceptable?
- As a first draft, yes. It must be reviewed by someone who knows the trade and the local audience before publishing.
