Why your Belgian website should be bilingual

In Belgium, language is a search criterion as much as a trust signal. A Dutch-speaking customer looking for a physio in Antwerp, a solar installer or a management tool will type the query in Dutch. A French-only website simply will not show up.

The usual reflex is to translate a French page word for word. That is a mistake: search habits differ. In Flanders people look for “kinesist” rather than “kinésithérapeute”, “boekhouder” rather than “comptable”. Each version deserves its own keyword work.

The right approach is to structure content for two languages from the start: separate URLs (/fr and /en or /nl), correct hreflang tags, genuinely translated content — never raw machine translation — and a language switch that keeps you on the same page.

Not everything needs a one-to-one translation. Pages that generate enquiries (services, pricing, contact) deserve careful translation. A secondary blog post can wait. What matters is that visitors never land on an empty page or an under-construction machine translation.

In practice, on the projects we deliver, the bilingual version costs 15 to 25% more than a single-language one and opens up a market twice the size. It is one of the best returns on investment a Belgian website can offer.
