An author page should explain who is responsible for a text. It is not a reason to fill gaps with invented biographies or qualifications. Publish only information that exists and is approved for that purpose.
Establish the person’s actual role
Fictional example: someone is the contact for technical questions but neither wrote nor reviewed an article. Naming them as its author would make a different claim from offering a contact.
Distinguish authorship, subject review and contact responsibility. Every visible attribution should make clear which role is meant. An existing team profile does not prove involvement in an individual article.
If an editorial team shares responsibility, describe that arrangement as concretely as the available facts allow. Do not invent a person or an expert quotation to fill the space.
Use the approved name or genuine editorial identity, its connection to the content and relevant articles. Add a photo, career history or external profiles only when they are authentic, approved and useful.
Structured data must match the visible page. Google’s ProfilePage documentation is not an invitation to mark up arbitrary archives as personal profiles.
If attribution cannot yet be established, keep that issue internal. A well-maintained article with traceable sources is preferable to a decorative author page with an invented background.
