At a glance
What we observed in this category
Mayo Clinic and Kaiser Permanente jointly lead the Medical services category, each scoring a composite of 16.2 with identical visibility of 12.5% and citation rates of 25.0%. Every other tracked brand sits at a composite score of 0.0, meaning the gap between the top two and the remaining 18 brands is total rather than marginal. Both leaders were previous non-performers, rising from ranks 5 and 11 respectively with visibility deltas of 12.5 percentage points each, suggesting a sharp and recent shift in how Google AI Mode surfaces medical service providers.
Johns Hopkins Medicine presents the clearest divergence between visibility and citation in this category. It holds a 25.0% citation rate, matching both Mayo Clinic and Kaiser Permanente, yet records 0.0% visibility, producing a composite of just 7.5. This means Google AI Mode is referencing Johns Hopkins content as a trusted source without naming the brand in its primary responses. Cleveland Clinic, HCA Healthcare, and all remaining ranked brands show zero on both metrics, confirming they are absent from AI-generated answers entirely.
The top cited sources in this category are dominated by aggregator and insurance-adjacent domains including ehealthinsurance.com, usnews.com, forbes.com, pacificprime.com, and healthcare.gov, alongside google.com and youtube.com. None of the 20 tracked medical service brand domains appear in this cited-sources list directly. This pattern indicates Google AI Mode is anchoring its Medical services responses on third-party rankers and insurance comparison platforms rather than on the provider brands themselves, which explains the near-zero visibility scores across the category average of 1.2%.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
