Healthcare AI Citation Study: 8248 AI Answers Measured

The short answer

In Healthcare, 8248 AI answers were measured between May 2026 and August 2026. The most cited platform is YouTube at 1.71%, ahead of Trustpilot at 1.33%. That ranking differs from the general one: Apple is cited 1.3 times more here than in the general ranking.

Healthcare is the flattest sector measured: no platform dominates, and the citations spread across a wide set of sources.

Key figures

• 301025 AI answers analysed between August 2025 and August 2026
• 1820738 citations extracted from those answers
• 131349 distinct domains cited at least once
• 5 models measured separately: ChatGPT, Gemini, Perplexity, Claude and Grok
• 79% of the questions asked in French, the rest in English

Which platforms the AIs cite in Healthcare

• YouTube: 1.71%
• Trustpilot: 1.33%

What this sector cites more than the average

• Apple: 0.58% here against 0.46% in the general ranking, 1.3 times more

The leading source model by model

• ChatGPT: Apple at 0.99%
• Gemini: Microsoft at 3.1%
• Perplexity: YouTube at 2.29%
• Claude: TripAdvisor at 2.5%
• Grok: Trustpilot at 4.5%

How to read these numbers

A citation rate of 2% means the source was cited twice for every 100 measured answers. Rates are computed per model against the number of answers of that model, so a model with a smaller sample never distorts a column. A source cited several times inside one answer is counted once per company block, which keeps a single verbose answer from dominating a month.

The distribution is worth as much as the ranking. The top three sources hold 53% of the citations counted in this table, 4 platforms sit above 1%, and YouTube is cited 1.3 times more often than Trustpilot. A market where three sources hold most of the citations rewards depth on those three rather than presence everywhere.

This sector was measured on 8248 answers, 76.5% of them in French, across all five models (ChatGPT, Gemini, Perplexity, Claude, Grok). The language mix matters when you read the ranking, because local platforms weigh more in French speaking markets.

What changed over the measured period

This sector was measured over 4 months, between May 2026 and August 2026, on 8248 answers, and 24 platforms recorded at least one citation. Its leading source, YouTube, fell from 3.17% in May 2026 to 0.77% in August 2026, which is the kind of movement that makes a ranking older than one quarter unreliable.

YouTube month by month in this sector

• May 2026: 3.17%
• June 2026: 3.08%
• July 2026: 2.4%
• August 2026: 0.77%

What this means in practice

A flat distribution usually means the models are cautious and pull from many places rather than trusting one. For a clinic or a health service, that removes the shortcut: there is no single profile to claim that unlocks visibility. What remains is the boring, reliable work, which is a complete and factual presence on your own site, a maintained booking or directory listing, and consistency of practitioner names and credentials everywhere they appear.

How to use this study

1. Publish practitioner pages with credentials, specialties and locations, written in plain sentences.
2. Keep booking and directory listings consistent with the site, because inconsistency is penalised by dilution.
3. Avoid promotional claims in health content, which the models tend to skip in favour of neutral sources.

How this study was measured

1. We run a panel of buyer questions every month, the questions people type before choosing a supplier.
2. Every question is sent to five AI: ChatGPT, Gemini, Perplexity, Claude and Grok.
3. Every answer is parsed, every cited source is extracted and normalised to a domain and a platform.
4. The citation rate is the number of citations of a source per 100 measured answers, computed per model so an uneven number of answers per model never distorts a column.
5. The month is closed, the dataset is rebuilt, and the public files are republished on data.sorank.com.

Limits of this study

1. This panel is not a neutral sample of the web. The questions come from the sectors our users operate in.
2. The panel leans French: 237930 answers come from questions asked in French and 63095 from questions asked in English.
3. Model coverage is uneven: 87008 answers from ChatGPT, 87004 from Perplexity, 87000 from Gemini, 20011 from Claude and 20002 from Grok. The two smallest samples are read as direction rather than as precise values.
4. A citation is not a click. This study measures what the AIs cite, not what a reader does next.
