Multilingual websites in Luxembourg: which languages to choose?

This is the most specifically Luxembourgish question in a web project, and the one where the most money is spent to no effect. The reflex is to translate everything into three languages "because the country is trilingual". In practice, that choice is paid for in maintenance and diluted visibility.

Start from your clients, not from demographics

Luxembourg has a very international population, but your clientele is not the country: it is a segment. Three simple indicators, available right now:

• the language of your incoming emails over the last six months;
• the language your phone calls happen in;
• the language of the quotes you already send.

If 90% of your exchanges are in French, an English version will mostly serve your peace of mind. If your clients are international companies based in Kirchberg or Cloche d'Or, English is probably more useful than French.

What each language actually brings

French covers the majority of local commercial searches and remains the administrative reference language. It is the default starting point for a local business.

English addresses international residents, the financial sector and foreign companies established in the Grand Duchy. It is often decisive in B2B and in services for expatriates.

German matters for cross-border clients from Germany, for the north of the country and for part of the resident population. It weighs more than people think in trades, healthcare and retail.

Luxembourgish is little used in online search but strong as a signal of belonging. A few elements (an "about" page, a welcome message) often produce more effect than a full translation.

What an extra language really costs

Count 20 to 40% of the build budget per language added. That figure surprises, because people only think of translation. But you also have to:

• adapt visuals and interface labels;
• check the layout, German being noticeably longer than French;
• declare the versions to each other correctly;
• and above all, maintain that version for life.

The last point is what costs the most over three years. Every new service, every price change, every announcement has to be reflected everywhere. A language version frozen for two years damages your image more than having no version at all.

The most common technical mistakes

Machine translation without review. It is spotted immediately and destroys credibility, especially in German.

Translating only part of the site. An English-speaking visitor who lands on an English page and then hits five French pages has a worse experience than if everything had been in French.

Using a single address for all languages. Each version needs its own URL, otherwise search engines can only index one.

Forgetting to declare the equivalences. hreflang tags tell each engine which version to serve to which visitor. Without them, your versions compete instead of complementing each other.

Redirecting automatically by browser language, with no way out. A visitor must always be able to choose another language, and engines must be able to reach every version.

A progressive approach that works

1. Launch in a single language, the one most of your clients use, with complete, properly written content.
2. Measure for three to six months: where visitors come from, their browser language, the enquiries received.
3. Add a second language on the pages that matter (offer, contact, references) rather than across the whole site.
4. Only add the third if the second produced measurable results.

This approach costs less, produces versions that are genuinely kept up to date, and avoids the most common scenario: three versions launched together, two of them abandoned within a year.
