Identity & Authority — The Lens

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

There is a significant technical authority gap; despite being a major global drug, the schema_json is null across all pages, missing critical Organization or Product structured data. While ‘Cathy’ and ‘Jerry’ are cited as authorities of experience, they have no digital footprint or Person schema. The site lacks outbound links to the specific peer-reviewed studies mentioned, relying instead on internal text assertions.

The marketing tone uses bold assertions like ‘dramatically lower bad cholesterol,’ but unlike generic BS sites, Repatha actually backs this with specific numbers (84% of patients below 55 mg/dL). The disconnect is not in the truth of the claims, but in the lack of direct citations to ClinicalTrials.gov or published journals within the body text to verify the ’10 Years of Impact’ claim.

Identity & Authority is read from the structured data first: whether the site declares who it is in machine-readable schema, with verifiable identity links. Below is the schema captured per page, then the external proof links that support (or fail to support) that identity.
