Technical audit
Indexing, crawling, speed, canonicals, structure: everything that stops Google from reading your site properly, identified and then fixed in order of impact.
SEO agency in Luxembourg
Your customers are still searching.
Be the first one they find.
SEO (search engine optimisation) is the service from AIxH, an SEO agency based in Luxembourg, that moves your business up Google's results: technical audit, site architecture and content, internal linking, structured data, local and multilingual SEO, and monthly reporting tied to your conversions. Behind the method: 27 years in the trade and nearly 40 years of combined experience of the Luxembourg market.
Every day, your future customers type what they need into Google. The top three results share most of the clicks. If your site is not among them, the demand still exists; it simply goes to someone else.
An SEO agency or a search engine optimisation agency in Luxembourg: both names describe the same work, moving your pages up on the queries your customers type, in French, German or English.
SEO is the work that moves you up and keeps you there: a technically clean site, pages that answer a real question better than anyone else's, and authority built on your subjects. No tricks and no shortcuts. Google's rules change constantly; the foundations have stayed the same.
Those foundations work twice. What ranks you in Google is exactly what gets you cited by ChatGPT, Gemini or Google's AI Overviews. SEO is the base; GEO extends it to the answer engines.
The method is carried by a team that knows the ground: Xavier Lesueur has worked the Luxembourg market since 2002, Grégory Camus since 2003, more than 45 years of combined experience of queries in three languages, the Greater Region and the local business fabric. The next generation is trained in-house: Kenza Battache, Project Manager, has been an SEO specialist since her first job.
What is included
What does AIxH's SEO service cover?
AIxH's SEO service covers six workstreams: the technical audit, keyword research and site architecture, content, internal linking, local and multilingual SEO, and measurement tied to your conversions, beyond rankings alone.
Keyword and intent research
The queries your customers actually type, the intent behind them, and the page architecture that answers them: one clear intent per page.
Content that ranks
Creating and optimising pages that answer better than your competitors' pages: a direct answer, sourced facts and a human review before anything goes live.
Internal linking
Pillar pages linked to their supporting content, descriptive anchors, and authority that flows to the pages that sell. Exactly what we apply to our own site.
Local and multilingual SEO
Luxembourg searches in three languages and lives in the Greater Region: local presence, language versions and consistent signals between them.
Measurement tied to the business
Search Console, GA4, rankings, and above all leads and conversions per page. A ranking is a means; the result shows in your enquiries and your sales.
Method
How does an SEO engagement work?
An SEO engagement with AIxH follows four steps: audit, consolidating the foundations, content and internal linking, then continuous measurement. The quote is drawn up after the audit: the price follows the scope (site size, languages, competition, state of the technical foundations) rather than a catalogue rate.
- Technical and keyword audit: The real state of the site (indexing, speed, structure) and the queries that matter for your market, prioritised by impact.
- Fixes and foundations: Technical blockers removed, structured data in place, architecture aligned with search intent.
- Content and internal linking: Missing pages created, existing ones optimised, and internal links that channel authority to the pages that sell.
- Continuous measurement: Rankings, impressions, clicks, leads: a monthly report linking every change to the actions taken.
Workstreams
Audit, technical, local: what do these three workstreams cover?
Three words come up in most of the enquiries we receive. Here is what they cover, what you get and who carries out the fixes.
SEO audit
Know what is blocking you and where to start
The audit requires read access to Search Console and GA4, then a full crawl of the site. It cross-checks the technical state, the queries that matter for your market and how your pages answer them. The deliverable is written: every finding is ranked by impact and effort, with the expected fix and the person who carries it out, on the AIxH side or on your web team's side. The audit opens every engagement: the quote is based on its conclusions.
Technical SEO
Foundations Google can read
Crawling, indexing, canonicals, speed, structured data, URL architecture: what Google must be able to crawl before judging your content. We diagnose the blockers and write up the fixes with their priority. AIxH carries out those that concern tags, structured data and content when access to the site allows it; code or server changes are specified for your developer or web agency, then checked after going live.
Local SEO
Be found where your customers are
In Luxembourg, the answer often comes in three languages and spills over into the Greater Region. We align your pages with the areas and audiences you actually serve, check the consistency of your contact details and your business structured data, and track results per country in Search Console. Your Google Business Profile and directories are reviewed in the audit; their day-to-day management is decided during scoping, depending on your business.
Specialisations
Two needs that call for a dedicated answer
Multilingual SEO
Your site exists in several languages and some versions receive few visits, or you are preparing a new language without knowing which pages to translate first. We choose with you the languages and pages to work on, adapt the content to what each audience searches for, organise the versions (URLs, hreflang, links) and track results language by language, as for MONDORF Domaine Thermal, handled in three languages.
Content strategy and architecture
Your site has grown project after project: services added, articles piling up, pages that no longer describe your business accurately. We map your offers and search intents, decide which pages to enrich, merge or create, give each one a role and a plan, then link the guides to the pages that sell. It is the method applied to aixh.com, where every service page points to its analyses and back.

Our own site as a test bed
Architecture, internal linking, structured data, Search Console tracking: every method we recommend to clients is applied and measured on aixh.com first.
“In 27 years, I have watched Google rewrite its rules dozens of times. What has never changed: a technically clean site that answers a real question better than the others. The rest is tooling.”
SEO x GEO
SEO or GEO: which do you need?
SEO is the base: Google remains by far the largest source of visitors for almost every business. GEO extends it: getting your business cited in the answers of ChatGPT, Gemini, Perplexity and Google's AI Overviews, which rely on the same foundations.
In practice: if your technical foundations and content are not yet up to standard, SEO comes first. If they already are, GEO becomes the lever that sets you apart. On most engagements, AIxH runs both as a single project: you do not pay for two services to get one piece of work.

FAQ
Frequently asked questions about SEO
What does an SEO agency in Luxembourg like AIxH do?
AIxH audits and fixes your site's technical foundations (indexing, speed, structure), builds a page architecture aligned with your customers' queries, produces and optimises content, strengthens internal linking and tracks rankings as well as conversions. All of it for the Luxembourg market and the Greater Region, in several languages where needed.
Who is the best SEO agency in Luxembourg?
There is no official ranking: compare on verifiable criteria. AIxH puts forward its own: a 5.0/5 rating on Google reviews, 27 years of uninterrupted SEO on the founder's side, nearly 40 years of combined experience of the Luxembourg market, measured results such as +55% traffic from Google Images for MONDORF Domaine Thermal, and a method detailed in our guide Choosing an SEO or GEO agency in Luxembourg: four criteria that never lie. Google Partner status and our Google Ads certifications belong to advertising and can be checked on the dedicated page.
How much does SEO cost?
The price is set by quote, after the audit. It depends on the size of the site, the number of languages, the competition on your queries and the state of the technical foundations. AIxH does not apply a catalogue rate. Pricing models, warning signs and the public grants you can apply for are detailed in our guide SEO agency fees in Luxembourg: quotes and grants. Write to hello@aixh.com to start the audit.
How long before SEO results show?
Technical fixes produce their first effects within a few weeks; progress on competitive queries builds over several months, the time it takes for Google to reassess the site and for authority to consolidate. Be wary of any promise of a guaranteed position: nobody controls Google.
SEO or GEO: where should you start?
With SEO. Generative engines give priority to clear, fast sites with real authority, which is exactly what SEO builds. GEO then extends those foundations to the answers of ChatGPT, Gemini or Perplexity. AIxH often runs both as a single project.
Do you do multilingual SEO?
Yes. Luxembourg searches in French, English and German, and the Greater Region widens the field further. AIxH works on the language versions and on the consistency of signals between them, as for MONDORF Domaine Thermal, whose content was handled in three languages. The method, from the choice of pages to per-language tracking, is detailed on our Multilingual SEO page.
How does AIxH measure SEO results?
With Search Console and GA4: impressions, rankings and clicks per query, but above all leads and conversions per page. A monthly report links every change to the actions taken, to separate what comes from the SEO work from what comes from the market.
Is SEO still useful in the age of AI answers?
Yes. The answers from ChatGPT, Gemini, Perplexity and Google's AI Overviews draw heavily on well-built pages with real authority. A site that is invisible in Google has very little chance of being cited by an AI: SEO remains the foundation of all visibility, classic or generative.
