Why clinician authorship is a ranking requirement
Healthcare is Google's archetypal YMYL category, content that could materially affect a reader's health, safety, or financial wellbeing. Google applies its strictest quality framework to medical content, which means E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is not a marketing concept but a ranking prerequisite.
What E-E-A-T looks like for a ranking healthcare page
- Clinician byline with real credentials. Name, qualifications (GMC registration for UK, state medical license for US, provincial college for Canada), specialty, years of practice, affiliations.
- Medical review attestation. “Medically reviewed by [Dr Name] on [date]” with a link to the reviewer's profile page.
- Peer-reviewed citations. References to published medical literature, PubMed, Cochrane Reviews, NICE guidelines (UK), CDC/NIH (US), CADTH (Canada). External .gov and .edu links are ranking signals in their own right.
- Person schema for every clinician, with credentials, alumniOf, memberOf, award properties.
- Organization / MedicalClinic / MedicalBusiness schema at site level with proper coverage of services, specialties, and accepted insurance/funding.
Practices that invest in genuine E-E-A-T architecture outperform competitors on YMYL queries by meaningful margins. The work is slower because clinician time is limited and expensive, but it compounds because Google increasingly rewards the signal and demotes content without it.
