Healthcare AEO: YMYL Standards, Medical Schema, and Clinician Authority for AI Citations
Healthcare is a YMYL vertical - Google applies its highest quality standards. Content that fails E-E-A-T requirements (no named clinician author, uncited medical facts, outdated review dates) will not be cited by AI systems regardless of other AEO optimizations.
Healthcare AEO operates under constraints that don't apply to other verticals: mandatory clinician authorship, primary source citation for every medical claim, annual content review cycles, regulatory compliance for treatment claims, and the practical limitation that Google suppresses featured snippets for some healthcare queries to prevent misinterpretation. These constraints are not obstacles - they are the documented standard that separates AI-cited healthcare content from healthcare content that AI systems skip as unreliable.

5 Non-Negotiable Healthcare AEO Rules
Non-negotiable requirements for healthcare content to achieve AI citation eligibility:
Cite primary medical sources - not secondary summaries
Every medical claim must link to a primary source: peer-reviewed study (PubMed citation), clinical guideline (AHA, ADA, USPSTF), or government health authority (CDC, NIH, NHS). AI systems and Google's YMYL quality raters scrutinize healthcare content source chains. A study summary that doesn't link to the original study fails YMYL credibility standards.
Named licensed medical author or reviewer required
Healthcare content requires named authorship by a licensed healthcare professional (MD, DO, PharmD, RN, PhD in relevant field) with verifiable credentials. Anonymous healthcare content or content attributed to 'editorial teams' without individual credentialed names has dramatically reduced AI citation probability. Include author bio with license number, institution affiliation, and specialty.
Include date-stamped review dates
Medical information becomes outdated - guidelines change, dosages are revised, new contraindications emerge. Healthcare AEO requires: original publication date, last medical review date (annually at minimum for clinical content), and the reviewing clinician's credentials. Google's QRGs specifically instruct raters to check medical content for currency.
Use MedicalWebPage or MedicalCondition schema
Schema.org provides healthcare-specific schema types: MedicalCondition (symptoms, causes, treatments), Drug (brand names, interactions, dosing), MedicalWebPage (medical content page with expertise signals). These schema types are specifically designed for YMYL medical content and directly signal healthcare content type to Google's classification system.
Comply with FDA and health advertising regulations
Healthcare AEO content that makes treatment claims, discusses drug benefits, or describes medical devices may fall under FDA advertising regulations. Content that constitutes 'off-label promotion' or 'disease claims' on dietary supplements has specific regulatory rules. Healthcare AEO must involve legal/regulatory review for any claims content.
