Website Translation vs Localization: Get It Right

Translating a website into French does not mean converting your Dutch copy word for word, but rewriting your message so it sounds natural and prompts action for a French-speaking audience. That difference between translation and localization decides whether your French-speaking visitors gain trust and fill in a form, or click away within ten seconds. In this article you will learn why a literal website translation puts off a Belgian French audience, where it goes wrong in tone, examples and CTAs, and how to approach it so your French site truly generates leads.

What is the difference between translating and localizing?

Translating converts words from one language into another; localizing adapts the entire message to the culture, context and expectations of the new audience. In a translation, the sentence structure and rhythm of your source language often linger, which makes the text technically correct but unnatural. With localization you rewrite: you choose different examples, a different way of addressing the reader, different arguments and sometimes a different structure, because what convinces a Dutch speaker does not automatically convince a French speaker.

For a B2B website, that distinction is commercially relevant. You are not selling individual words, you are selling trust and clarity. A visitor who senses that a text came “out of a machine” or “out of Dutch” unconsciously doubts the rest of your offer. Localization makes your French-language page read as if it were originally written in French, and that is exactly what is needed to move someone toward an enquiry. The same logic applies, incidentally, to every page that has to build trust on a B2B website.

Why does a literal translation put off French-speaking visitors?

A literal translation stands out for the wrong reasons: it sounds strange, sometimes even rude, and that undermines trust before you have even made your point. Belgian French has its own words and habits that a Dutch-speaking copywriter or an automatic translator does not know by default. French-speaking Belgians use “septante” for seventy and “nonante” for ninety, for example, where the French of France uses “soixante-dix” and “quatre-vingt-dix”. Meal names differ too: in Belgium, “déjeuner” is breakfast and “dîner” is lunch, whereas in France it is not. Small things in themselves, but they immediately signal whether a text was written for “this market” or not.

Then there is tone. French is more formal in business communication than Dutch. Where a Flemish B2B site happily uses the informal address and gets straight to the point, a French-speaking business audience often expects the polite “vous” and a slightly more elaborate, courteous wording. A direct translation of your breezy informal address can therefore come across as abrupt or careless. The message is identical, but the register is off, and register in French is a strong signal of professionalism.

The third problem is recognizability. A text full of references to Flemish situations, Dutch-language terms or examples that only exist north of the language border makes a French-speaking reader feel they are not the intended customer. And someone who does not feel addressed will not convert.

What should you localize beyond the words?

Beyond the text itself, you localize the tone, the examples, the evidence and the calls to action, because these are the elements that drive conversion. A French version that is correct only at the word level but keeps the same Flemish references and CTAs remains a translated site rather than a French-language site.

Think concretely about these layers:

• Tone and address. Deliberately choose “vous” or “tu” and keep it consistent across the whole site. For most B2B contexts in French-speaking Belgium, “vous” is the safer choice.
• Examples and references. Replace Flemish cases, sectors and place names with examples a French-speaking audience recognizes. Show customer stories that are relevant to that market, without inventing anything that does not exist.
• Evidence and figures. Numbers, prices, VAT mentions and date formats must be right for the Belgian context, not carried over automatically from a French or Dutch template.
• Calls to action. A CTA is not a word but a promise. “Request your free quote” does not get stronger through a literal translation, but through wording that sounds equally inviting and clear in French. Which verbs, which urgency and which form of politeness work differs per language. It pays to treat your calls to action as separate copy and not as an afterthought.

Do not forget the forms either. Field labels, error messages, confirmation texts and placeholder text are often the last thing to be translated, even though they sit exactly at the moment of conversion. A French-speaking visitor who sees a Dutch error message drops out. So read through your entire conversion path in forms, not just the running text.

How do you approach a French-language B2B site technically?

Technically, you treat the French version as a full set of pages with their own URLs, their own copy and their own findability, not as a hidden copy behind a language button. The most common approach is a separate URL structure per language, for example with a folder (/fr/) or a subdomain, so that search engines and visitors treat each version as its own page.

To prevent your Dutch-language and French-language pages from competing with each other in the search results, you use hreflang signals to indicate which version is meant for which audience (nl-be and fr-be). That is a separate and error-prone topic; how it works is explained in our guide to hreflang tags for Belgian B2B. The most important principle: each language version must be findable, readable and convertible on its own.

Just as important is who writes the copy. Good localization is not left to an automatic translation tool alone. Machine translation can produce a first draft, but a native speaker with a feel for B2B and for the Belgian context has to rewrite and proofread the copy. That is not a luxury: it is the difference between a site that generates leads and a site that looks “finished but strange”. Which platform you build on, whether it is Webflow, WordPress or a headless setup, makes no difference to the principle; multilingualism is possible on each of those platforms, each with its own management pros and cons. If you want to weigh that up objectively for your situation, our web design agency helps you make the right choice.

When are you better off not starting a French version?

Only start a French-language site if you genuinely serve and can maintain that market, because a half-finished or sloppy translation harms your credibility more than no French version at all. A French-speaking visitor forgives the absence of a French site more readily than a French site full of mistakes, because the latter suggests you do not take their market seriously.

Ask yourself a few honest questions. Do you have French-speaking sales or support to follow up the leads that come in? Can you keep the French content up to date when your Dutch site changes, or will one version soon fall months behind the other? Do you have access to a native speaker who can write and guard the copy? If the answer to those questions is no, you are better off investing your budget first in a stronger single-language site that is fully correct. That fits how we at Customer Impact look at this kind of choice: honest advice, focused on leads and revenue, and realistic about what a website does and does not do for you.

The short summary

Translating a website into French is only effective if you localize rather than translate literally. The difference lies in tone, examples, evidence and calls to action, and in the choice to treat each language version as its own conversion path with the right technology underneath. Literal translation puts off a Belgian French audience because it sounds unnatural and undermines trust; localization wins that trust back. Only take it on if you genuinely serve the market and can keep maintaining the French content. For the broader context of a conversion-focused B2B site, see our guide to having a B2B website built.
