The complete guide to building a website in Luxembourg

This guide gathers the questions Luxembourg business owners ask before launching a website, in the order they actually come up. It is not neutral: it reflects the way we work. But every recommendation comes with the reasoning behind it, so that you can decide otherwise with your eyes open.

1. Which type of site to build

The type of site follows from what you expect of it, not from your sector. One question keeps coming back: what should a visitor do after thirty seconds? Call you, book, buy, download a document, or simply recognise you as credible.

The classic trap is choosing the most ambitious format "so we don't have to redo it". In practice a well-built brochure site extends without difficulty, whereas a shop launched with no stock and no logistics stays an empty shell that is expensive to maintain. See brochure website design for the most common format.

2. What budget to plan for

A website budget has three parts: the build, recurring costs, and improvements. The first is visible in the quote; the other two are often discovered too late.

• Build: from €1,500 for a single page to €15,000 and above for specific development.
• Recurring: domain name (€30 – €60 / year), hosting (€10 – €50 / month), optional maintenance (€60 – €250 / month).
• Improvements: a new page, a new feature, a campaign. Budget around 10% of the initial cost per year.

A simple rule for deciding: if the site is meant to generate enquiries, compare its cost with the value of a client. A business with an average deal of €5,000 pays for a €6,000 site with two clients. A business with a €50 basket has to think in volume, therefore in visibility, therefore in content. The full breakdown is on the pricing page.

3. Agency, freelancer or on your own

All three are legitimate. What separates them is less the quality of the result than the workload left on your side and what happens when something goes wrong.

The real deciding factor is not budget but your availability. A director who cannot spend ten hours on their site will lose more in time than they save in fees. The topic is developed in web agency or freelancer in Luxembourg.

4. Which technology to choose

Technology does not interest your clients, but it determines what you will be able to do in three years and at what cost. Three families coexist.

Two questions settle it without being technical: who could take this site over if we part ways, and what happens if the vendor doubles its price? The answers often eliminate one option immediately. See which CMS should a Luxembourg company choose.

5. How long the build takes

Landing page

2 – 3 wks

Brochure site

3 – 5 wks

Custom build

6 – 10 wks

These assume feedback from you within 48 hours. In practice it is content that pushes projects back: copy not written, photos missing, approvals waiting for a meeting. A five-week project that takes twelve rarely has a technical problem. See how long does it take to build a website.

6. Which domain name to choose

• Prefer .lu if your clientele is Luxembourgish: it signals local roots to visitors and to search engines alike.
• Short and pronounceable: the name has to be dictatable over the phone without spelling it out.
• Avoid multiple hyphens and digits, which cause typing errors.
• Register close variants (.com, a common misspelling) and redirect them to the main domain.
• The domain must be in your name, not the provider's. That is the most important point on this list.

7. Which hosting to choose

Three criteria are enough: where the servers are, how fast they are, and how good the support is. For a Luxembourg company, hosting inside the European Union simplifies GDPR compliance and brings the servers closer to your visitors. A brochure site does not need a dedicated server: serious shared hosting or a modern platform is ample, between €10 and €50 a month.

Check three things before signing: how often backups run and how they are restored, the support response time, and whether you can leave with your data without depending on the host.

8. Which legal obligations to anticipate

A professional site published in Luxembourg must clearly identify its publisher, inform about personal data processing and obtain valid consent before any non-essential tracker.

• Legal notice: company name, legal form, address, registration number, contact, publishing director, host.
• Privacy policy: data collected, purpose, retention period, recipients, individual rights.
• Cookie banner: prior consent, refusing as easy as accepting, no advertising tracker before acceptance.
• Terms and conditions if you sell online, with the right of withdrawal and delivery terms.
• Accessibility: mandatory for the public sector, recommended for everyone. An accessible site is also better understood by search engines.

9. Which languages to use

This is the most specifically Luxembourgish question, and the one where the most money is wasted. The reflex is to translate everything into three languages. But a poorly maintained language version costs more than it earns: frozen content, approximate translation, and pages competing with each other.

1. 01Start from your real clientele, not from the country's demographics. Look at the language of your incoming emails and calls.
2. 02One language handled completely beats three half-maintained versions.
3. 03If you translate, translate everything: an orphan English page inside a French site serves neither.
4. 04Declare the versions correctly (hreflang tags) so each visitor gets the right one and none competes with the others.
5. 05Plan for maintenance: every update will have to be reflected in every language, for as long as the site lives.

10. How to make the site visible

Visibility is built on three planes that do not substitute for one another. The first is technical: structure, speed, markup, structured data. It is obtained at build time and is not redone every month. The second is editorial: pages that answer precisely what people search for. The third is reputation: being cited, referenced and recommended somewhere other than your own site.

In Luxembourg, local search carries real weight. An up-to-date business listing, identical contact details everywhere and a few citations on relevant Luxembourg sites often produce more effect than ten blog posts. Language models follow the same logic: they repeat what is factual, structured and confirmed by several sources.

11. How to measure performance

• Search Console: impressions, clicks, positions, indexing errors. Free, essential, to be connected at go-live.
• Traffic statistics: pages viewed, sources, devices. Choose a privacy-friendly tool to limit consent constraints.
• Enquiry tracking: how many forms, calls, bookings. It is the only metric that really counts.
• Real-world mobile speed: measured in the field, not only in the lab.

A quarterly review is enough in the first year. Checking rankings every week leads to decisions taken on noise.

12. How to choose your provider

1. 01Ask to see three sites delivered in the last twelve months, and check their speed on your own phone.
2. 02Ask who will actually work on the project, and who will answer in six months.
3. 03Check that the quote states the number of pages, the languages, the features and the exclusions.
4. 04Ask who owns the code, the content and the domain name at the end.
5. 05Ask what happens if you leave: recovering files, transferring hosting.
6. 06Be wary of a promise of first position on Google: nobody can guarantee it.

13. The mistakes that cost the most

14. What maintenance costs

Between €60 and €250 a month depending on the technology and the scope. A custom-built site needs less routine upkeep than a CMS loaded with plugins, but requires a provider able to work on the code. A maintenance package usually covers technical updates, backups, uptime monitoring, security fixes and a defined volume of changes.

Maintenance is not compulsory. It becomes so if your site takes payments, stores personal data or is your main acquisition channel.

15. When to rebuild your site

The average lifetime of a professional website is three to five years. But age is not a reason: the reason is a signal. A lasting drop in enquiries at constant traffic, an inability to edit content, technology that is no longer maintained, a message that no longer matches the business. As long as none of those appears, the money is better spent enriching the existing site. The approach is detailed on the website redesign page.
