The verdict in three sentences
Before booking an appointment, some patients of a fertility clinic in Luxembourg now ask AI assistants like ChatGPT about treatments, waiting times, coverage and how to choose a centre. These tools draw on publicly available information: a clinic whose pages are vague, contradictory or only in French risks being described wrongly or left out. The only honest way to judge is a dated record of the answers to the same questions, and no provider can promise that an AI assistant will recommend you.
What patients ask AI assistants
The Grand Duchy has a very international population: cross-border workers, EU officials, finance professionals. Questions come in several languages, often late in the evening, and they are precise.
| Question put to the assistant | Common language | What the assistant should find about you |
|---|---|---|
| Where can I do IVF in Luxembourg and how long is the wait? | French | Treatment page with dated indicative waiting times |
| Wie läuft eine Kinderwunschbehandlung in Luxemburg ab? | German | Patient journey in German, clear steps |
| Is IVF covered by the CNS for expats? | English | Coverage page linking to the official source |
| Do I need tests before the first appointment? | French | First consultation page, documents to bring |
| Egg freezing in Luxembourg: is it possible and at what age? | French or English | Dedicated page, within the applicable legal framework |
| Fertility centre in Luxembourg or Belgium: what should I compare? | French | Factual information on services and access |
| What success rates does this clinic publish? | All | Only official data, explained honestly |
| Does the team speak Luxembourgish or English? | English | Languages spoken by the team, clearly shown |
This content is health information: professional conduct rules for medical professions, caution with success figures, no promise of pregnancy. On data, the GDPR applies under the supervision of the CNPD: forms should not collect detailed medical history. This is not legal advice.
Why some clinics appear and others do not
AI assistants do not choose at random. They repeat what is consistent, verifiable and often echoed elsewhere.
| Factor | What helps | What hurts |
|---|---|---|
| Consistent information | Same name, address, hours and services everywhere | Different details across directories |
| Factual pages | One page per treatment, plain language, update date | Generic pages, jargon, 2019 content |
| Languages | Pages written in French, German and English | One language only, or machine translation |
| Third-party mentions | Health directories, local press, patient associations | No presence beyond the website |
| Structured data | Organisation, address and services marked up | Nothing machine-readable |
| Reviews | Genuine reviews where permitted | Reviews solicited against the rules |
The corresponding work covers, in broad terms, a baseline of what AI assistants say, aligning public information, clarifying key pages in several languages and tracking over time. For a Luxembourg clinic, multilingualism weighs more than elsewhere: a site in French, German, Luxembourgish and English is a multilingual project whose languages are set in the quote.
What it costs on the market
This is a young market and prices vary widely. Ranges below are a 2026 ballpark, based on typical agency quotes in the Benelux and neighbouring countries:
| Service | Format | Indicative range |
|---|---|---|
| AI visibility diagnostic | Fixed fee | EUR 2,000 to 6,000 |
| Ongoing support | Monthly | EUR 1,500 to 5,000 a month |
| Writing or rewriting medical pages | Per page per language | EUR 300 to 800 |
| Medical translation reviewed by a native speaker | Per page | EUR 120 to 350 |
| Quarterly dated record only | Per quarter | EUR 500 to 1,500 |
At Kolonell, this work is priced on quote, after a diagnostic. Be wary of offers that promise a place in the answers: AI assistant behaviour changes, and nobody controls it.

Measurement comes down to a dated record: a fixed list of 20 to 40 questions, asked in the same languages at regular intervals, with the answers archived. Three indicators are enough to decide: the share of answers that mention your clinic, the accuracy of what is said (address, treatments, languages, coverage) and the errors to correct at source. Read this record alongside first-appointment requests, which remain the final judge.
Mini case study
Illustrative example: Centre Moselle Fertilité, a 12-person team in Luxembourg City. An initial record of 30 questions in three languages shows the clinic mentioned in 4 answers, about 13%, and 3 answers giving an old address. The clinic commissions a diagnostic at EUR 3,500 and the rewriting of 10 pages in 3 languages at EUR 450 each, so 30 x 450 = EUR 13,500. Total budget: EUR 17,000. Six months later, the same record shows whether the address errors have gone and whether the share of mentions has moved, with no target promised in advance.
FAQ
Do AI assistants like ChatGPT really recommend clinics?
They often name centres when asked where to seek treatment. On a 30-question record, the share of answers naming a given clinic varies widely, from 0% to more than half.
Can we publish our success rates to be cited more?
Only official data, with its source, year and an honest explanation. A bare figure without context exposes the clinic and can be repeated misleadingly.
Do we really need four languages?
Not necessarily. If 70% of requests arrive in French and English, starting with those two is reasonable, with German and Luxembourgish to follow.
How long before we see a change?
Corrections to public information can show up within weeks, but allow 3 to 6 months to judge on a full record. Nothing is guaranteed.
Is this different from Google SEO?
The two overlap: clear, consistent pages serve both. Measurement differs, since you track archived answers rather than positions, with a quarterly record at EUR 500 to 1,500 as a ballpark.
