SEO audit for websites in Luxembourg
Luxembourg is the hardest kind of market for a template: three administrative languages, an English-speaking business world, and neighbours in France, Belgium and Germany whose search results overlap with yours. Most of the SEO work is deciding which language versions to publish and how to stop them competing.
The notes below are written for sites aimed at Luxembourg City, Esch-sur-Alzette or the cross-border workforce that commutes in each day.

Market notes for Luxembourg
Which of the four languages deserves a version?
Luxembourgish, French and German are the three administrative languages under a law of 1984; English is accepted in many services and dominates parts of the business world. In practice written German is the main language of the press, French is often the main language in shops, and children first learn to read and write in German. These habits show up in what people search for and read.
A four-language site is rarely realistic. Choose the two or three versions your customers really use, build each one properly, and add the rest only when you can keep them current. A professional-services firm may find French and English enough, a consumer brand may want French and German, and a public body will probably add Luxembourgish. Look at Search Console’s query languages before you decide.
Sharing a language with France, Belgium and Germany
Your French and German pages compete with pages written for France, Belgium and Germany. Prices in euro do not differentiate the markets, because all four countries use the same currency. What does differentiate them is local detail: a +352 number, Luxembourg VAT, Luxembourg delivery and legal notices. Put that detail in the page so that fr-LU or de-LU is more than a label.
Cross-border commuters make the overlap bigger, because people living in France or Germany search for Luxembourg employers and services. If a page is meant for them too, use the plain fr or de tag instead of a Luxembourg-specific region. And do not auto-redirect visitors by country or language: crawlers often visit from a single location and would never see the other versions.
Luxembourgish: a small written footprint, real brand value
Luxembourgish is the national language, but much commercial writing is in French or German. A /lb/ section is therefore an optional signal of local roots rather than a necessity, and it works best for local brands, public services and cultural institutions. It has a valid ISO 639-1 code (lb), so lb-LU is a correct hreflang value.
The letters ä, ë and é appear in Luxembourgish text, alongside the full set of French accents on French pages. Keep the encoding consistent as UTF-8 and use a single slug policy across all languages.
Finance, regulation and trust signals
Luxembourg is an international financial centre, and many sites in it deal with money, law or insurance. Google applies stricter quality expectations to pages that can affect people’s finances or wellbeing. Show who writes the content, give their credentials, add publication and review dates, and state your regulatory status where the law requires it; for financial services the supervisor in Luxembourg is the CSSF.
Add Organization markup with your registered name and address, and keep the same details on the contact page, the footer and the legal notice. Differences between them are an easy way to look less trustworthy.
Copy-ready examples for Luxembourg
Both snippets use placeholder data. Replace the domain, name, street, phone number, coordinates and prices with your own before you publish them.
hreflang tags
This set covers 4 versions (fr-LU, de-LU, en-LU, lb-LU) plus an x-default. Put the same full set in the <head> of every language version, each page listing itself too; Google ignores pairs that do not link back.
<link rel="alternate" hreflang="fr-LU" href="https://example.lu/fr/" />
<link rel="alternate" hreflang="de-LU" href="https://example.lu/de/" />
<link rel="alternate" hreflang="en-LU" href="https://example.lu/en/" />
<link rel="alternate" hreflang="lb-LU" href="https://example.lu/lb/" />
<link rel="alternate" hreflang="x-default" href="https://example.lu/en/" />LocalBusiness JSON-LD
The postcode follows the Luxembourg format (4 digits; an older ‘L-’ prefix still appears) and the telephone starts with +352. Use the most specific business type that fits, and keep every detail identical to your footer, contact page and map listing.

}What the audit looks at
What the audit checks for Luxembourg
hreflang across up to four languages
We check reciprocal tags for fr-LU, de-LU, en-LU and lb-LU, valid codes and that every page lists itself.
Canonicals and duplicates with neighbouring markets
If your fr-LU page is near-identical to a French-market page on another domain or folder, we flag the canonical and hreflang setup.
Automatic redirects by language or country
We look for redirects that send visitors, and crawlers, to a single language version without a crawlable link to the others.
Organization schema and consistent details
The audit validates required properties and checks that the address and telephone match between schema and visible text.
Questions about SEO in Luxembourg
Should a Luxembourg site have a Luxembourgish version?
It is optional. Luxembourgish is the national language, but a lot of written commerce is in French or German, so lb is most useful for local brands, public services and cultural bodies. When you add it, use lb-LU.
Is fr-LU different from fr-FR?
Only if the content differs, for example in a +352 number, Luxembourg VAT, delivery and legal notices. Because France and Luxembourg both use the euro, price alone does not separate the pages.
Does .eu help me rank in Luxembourg?
No. Google treats .eu as a generic domain, so it does not signal Luxembourg. A .lu domain or an /lu/ folder with hreflang says more.
How is a Luxembourg postal code written?
As four digits, such as 1111. Older addresses still show an ‘L-’ prefix, so choose one form and use it everywhere.
Is Luxembourg in the euro area and Schengen?
Yes. It is a founding member of the EU, part of the euro area and part of the Schengen area.
