The State of AI Visibility in Singapore Fertility Care 2026

When a couple in Singapore asks AI for the best fertility clinic, who gets named — and who doesn't? We asked ChatGPT, Perplexity, Gemini and Claude the 12 questions patients actually ask. Across 48 answers, six clinics captured two-thirds of every recommendation, and the four AIs barely agreed on a winner.

1. Six clinics own the conversation

We counted how many of the 48 AI answers named each provider. The result is steeply concentrated: a handful of well-known centres appear again and again, while everyone else fights for scraps. These six were named in roughly half their answers or more:

The pattern is the one AI visibility always produces: the rich get richer. Clinics that are already written about — in "best of" listicles, on Reddit, in news features — are the ones AI repeats. New or under-marketed clinics, however good clinically, simply aren't in the source material the models draw from.

2. There is no single "best" — it depends which AI you ask

The most striking finding: the four assistants don't agree. Each has its own logic for what "best" means, so each crowns a different clinic. A patient asking ChatGPT and a patient asking Perplexity are sent to different doors.

For clinics, the lesson is that you cannot optimise for one algorithm. Winning on Perplexity is a reviews game; winning on ChatGPT is a citations-and-content game; winning on Gemini is an established-entity game. AI visibility means showing up across all of them.

3. Most of Singapore's fertility providers are invisible

Behind the top six is a long tail. Beyond about eight names, providers showed up only when a question got specific — a location ("east side"), a niche ("low AMH"), or "best reviews." Of the ~25 fertility providers operating in Singapore, roughly 19 appeared in two or fewer of the 48 answers, and several never appeared at all. To AI — and therefore to the patients who now ask AI first — they essentially do not exist.

This is the gap that AI visibility work closes. It is not about being the best clinic; it is about being legible to the models: a recognised entity, present in the sources they trust, with structured, answer-ready information.

4. What AI actually trusts

We logged the sources each answer cited. They cluster into five buckets — and notice how little of it is the clinic's own marketing:

• Independent listicles & guides — HeyBaby.sg, thebestsingapore.com, comparison and "best fertility clinic" round-ups. The single biggest driver of which names appear.
• Community & forums — Reddit (r/askSingapore, r/singapore) threads from real patients.
• Google reviews & aggregators — ratings and review counts (Perplexity leans on these almost entirely).
• Authority & government — MOH ART statistics, MediSave/co-funding pages, the public hospitals' own sites.
• Clinic-owned pages — used mostly for success-rate numbers (e.g. published IVF outcome tables), not for the recommendation itself.

The takeaway is uncomfortable but useful: polishing your homepage barely moves your AI visibility. What moves it is getting named in the third-party sources AI reads — the listicles, the forums, the reviews — and giving the models clean, structured facts to extract.

What this means if you run a clinic

• Audit where you stand first. If you're not in the top eight, you're likely in the invisible tail — and you can't fix what you haven't measured.
• Get into the sources, not just onto your site. Listicles, directories, Reddit, and earned reviews are what AI repeats.
• Give AI clean facts to quote — structured pages, a consistent business entity, and transparent, well-formatted information (the way the top clinics publish their success rates).
• Don't chase one engine. Reviews win Perplexity; citations win ChatGPT; entity strength wins Gemini.
