Web agencies in Brussels: the city where a single-language website misses half the market

Brussels is officially bilingual, economically international and concentrates most Belgian demand in one city. It is also where a language mistake costs the most because it is invisible: your website works perfectly, but half your potential customers simply never find it.

Three intersecting languages

French dominates everyday use, Dutch has equal official status, and English has become established in practice through the European institutions, lobbying organisations, international firms and a substantial expatriate population.

In practice, the same service is searched for using three different sets of words, and each version of your website captures only its own. A French-only website exists for one-third of the market.

What multilingual really costs

A second language is not a translation line item; it is a second website version. Separate URLs, correct hreflang tags so Google serves the right version to the right person, separate SEO and twice the maintenance for every change.

Allow 40 to 70 per cent of the first website’s price. A quote offering Dutch for a few hundred euros is selling automatic translation: Google treats it as low-value content, and a Flemish reader spots it within three lines.

In this market, poor Dutch does more harm than no Dutch at all. A carefully written French-language website is better than publishing an approximate version that undermines the whole business’s credibility.

A strategy that works on a tight budget

• A complete, carefully written French website is the foundation and already covers most everyday use.
• Two or three key pages translated into Dutch by a professional translator: home, the main service and contact. Not the whole website.
• An English page if your sector involves institutions, consultancy or expatriation.
• Correctly implemented hreflang tags from the start, even for three pages. These tell Google which version to show to whom.

This approach costs a fraction of a complete trilingual website and captures the main queries that matter. Expand afterwards if enquiries follow.

Brussels prices

The Belgian market sits slightly below France for template websites and at roughly the same level for bespoke builds. Allow €1,000 to €3,500 for a single-language template business website, and €3,500 to €12,000 for bespoke development.

The difference comes from multilingual requirements, which are a structural question here rather than an optional extra, and which many quotes price poorly or not at all.

Competition is much lower than in Paris

Search data is clear: Brussels queries show solid volumes with substantially lower ranking difficulty than major French cities. Some national phrases, such as website creation in Belgium, have very low difficulty.

The reason is simple: the market is smaller, so fewer agencies compete in it, and many of those that do neglect one of the two languages. There is still room on both sides.

Mandatory information: do not copy it from France

Belgian law requires the ten-digit enterprise number from the Crossroads Bank for Enterprises to be displayed, along with the VAT number, legal name and registered office address.

A privacy policy copied from a French template cites the CNIL rather than the Belgian Data Protection Authority. People notice that detail, and it weakens the professionalism of everything else.
