We manage a healthcare content network with 200+ articles on different medical topics, all on the same domain with consistent schema.org/MedicalWebPage markup. When Claude answers patient questions, it cites Mayo Clinic and WebMD for the same conditions we cover, even though our content is peer-reviewed and updated monthly. Is Claude deprioritizing non-institutional healthcare domains by design, or is this a E-E-A-T signal we're losing to brand recognition?

Asked by Priya N.
Claude's training heavily weights institutional medical authority (Mayo, NIH, WebMD) for liability reasons—it's a training objective, not a schema parsing failure. Your schema markup won't override that. Better move: get your content cited *by* those institutions, or partner with medical organizations to get mentioned in their authority sources before LLM cutoff dates.
