The verdict in three sentences
Some of the future patients of a fertility clinic in Amsterdam now put their first questions to AI assistants like ChatGPT, before opening Google or calling a GP. These assistants cite clinics whose public information is consistent, factual and verifiable, and often ignore those whose site stays vague or contradictory. The work is measured with a dated record of the answers to the same questions, costs 1,500 to 6,000 EUR per month on the 2026 market, and Kolonell prices it on quote.
What patients ask AI assistants in Amsterdam
The fertility journey is long, intimate and expensive. Patients compare possible treatments, waiting times, reimbursement conditions under Dutch basic insurance, the language of consultation and the team's reputation. Many are English-speaking expats, which makes language a central question. Here are realistic phrasings:
| Question put to the assistant | What the patient really wants | What the answer must be able to rely on |
|---|---|---|
| Which fertility clinics in Amsterdam see English-speaking patients? | A consultation without a language barrier | A clear page on the languages of doctors and front desk |
| Which clinic in Amsterdam should I use to freeze my eggs at 36? | A preservation pathway and its steps | A dated treatment page, with conditions and limits |
| Wat kost een IVF-behandeling in Amsterdam zonder vergoeding? | The real cost outside reimbursement | A public, up-to-date fees page |
| How long is the waiting list for IVF in Amsterdam? | A concrete delay | An updated waiting-time indication, with its date |
| Is a private fertility clinic in Amsterdam better than a hospital? | An honest comparison | A factual explanation of the offer, with no disparagement |
| Can same-sex couples get donor treatment in Amsterdam? | Whether the clinic welcomes their situation | A donor programmes page, within the local legal framework |
| What success rates does this clinic publish? | A reliable figure | Figures from an official or professional framework, with their method |
The last row is the most delicate. If an assistant finds no sourced data, it may answer vaguely or repeat an old figure. The only good answer is to publish what is allowed, with method and period, and never a promise of pregnancy.
Why some clinics appear and others do not
Assistants build their answers from what they find and cross-check. A few factors come back in every diagnostic:
- identical information everywhere: name, address, doctors, languages, opening hours, on the site, health directories and local listings;
- factual pages per treatment, rather than a single promotional text;
- third-party mentions: local press, patient associations, partner hospital pages;
- structured data describing the clinic, its practitioners and its services;
- reviews, within what professional rules and the platform allow;
- freshness: a waiting-times page dated 2023 works against the clinic.
Health advertising and health data are regulated in the Netherlands. The GDPR (AVG in Dutch) applies, supervised by the Autoriteit Persoonsgegevens, and health data are a special category under it. Doctors' professional rules also limit claims. This is not legal advice: any page touching on outcomes or treatments should be cleared by your medical director.
What the work covers, what it costs and how it is measured
In broad terms, the work covers a diagnostic of current answers, bringing public information into line, clarifying treatment and fees pages in Dutch and English, and tracking over time. It is an emerging market: the rates below come from typical agency quotes and public rate pages, as a 2026 ballpark.
| Item | 2026 market range | Note |
|---|---|---|
| One-off diagnostic of AI answers | 1,500 to 5,000 EUR | Depends on number of questions and languages |
| Monthly retainer (generalist agency) | 1,500 to 3,500 EUR | Often bundled with SEO |
| Monthly retainer (health specialist) | 3,500 to 6,000 EUR | Medical review included or not |
| External NL/EN medical copywriting | 0.10 to 0.18 EUR per word | External market assumption |
| Health public relations | 2,000 to 5,000 EUR per month | Market assumption, optional |
| Kolonell | On quote | Depends on scope and languages |
Measurement should stay simple and verifiable:
| Indicator | How to read it |
|---|---|
| Share of answers citing the clinic | Example: 3 answers out of 20 questions, i.e. 15% |
| Accuracy of what is said | Languages, address, treatments, fees correct or not |
| Tone and context of the mention | Cited as an option, as a reference or with reservations |
| Month-on-month change | Same question list, same recorded date |
| Consultation requests naming an AI as source | Question added to the first-contact form |

Mini case study
Illustrative example: Grachten Fertility Centre, a private clinic with 6 doctors in Amsterdam-Zuid. Across 20 questions asked in English and Dutch, the clinic appears in 2 answers (10%), one of them with an old address. The director plans a diagnostic at 3,000 EUR, then 6 months of work at 2,500 EUR, i.e. 15,000 EUR. She adds 12,000 words of bilingual medical copywriting at 0.14 EUR per word, an external market assumption, i.e. 1,680 EUR. Total: 19,680 EUR. If she assumes, as a hypothesis, an average value of 5,000 EUR per new self-funded patient pathway, about 4 new patients (19,680 ÷ 5,000 = 3.9) cover the spend. The decision criterion: accuracy of the answers and their change over 6 months, not a promise of a medical outcome.
FAQ
Do patients really use AI assistants to choose a fertility clinic?
Increasingly, especially for first questions about treatments, costs and consultation language. A record across 20 typical questions is enough to see whether your clinic is cited and whether the information is right.
How much does an AI visibility diagnostic cost in Amsterdam?
As a 2026 ballpark: 1,500 to 5,000 EUR for a one-off diagnostic, depending on the number of questions and languages. Kolonell scopes this diagnostic on quote.
Can we publish our success rates to be cited more?
Only data from an official or professional framework, with method and period, cleared by the medical director. A lone figure without a denominator risks misleading patients and being repeated as is.
How quickly do answers change?
First corrections of wrong information can show within 2 to 4 months, while lasting presence in answers takes more like 6 to 12 months. Nothing is guaranteed, hence the dated monthly record.
Do we need a site in Dutch and English?
In Amsterdam, yes in most cases: a large share of international patients ask their questions in English. Two consistent versions stop the assistant from mixing contradictory information.
