Genentech
(https://herceptin.com) 📸 Data Snapshot: May 30, 2026Inspect 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.
Authority is robustly established through Organization schema for Genentech and the inclusion of high-authority external citations. While the NCCN Guideline citations (2019) are stale relative to the 2026 system date, they represent legitimate medical authority footprints rather than manufactured expertise.
Marketing tone is almost entirely suppressed by regulatory necessity. Every performance claim, such as the 2.4 million people worldwide taken the Herceptin journey, is moderated by footnotes explaining the calculation methodology and extensive lists of potential serious side effects.
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.
