## Why it matters

AI systems build a knowledge graph of authors and organizations. Complete author profiles increase content credibility, and AI models prefer to cite content from identifiable experts in a given field.

## In practice

Articles on Mayo Clinic always include the doctor's name, specialization, and credentials. That's why AI models prioritize Mayo Clinic over anonymous health websites for medical questions.

## How be1st checks it

Checks the completeness of information about the author and the entity behind the site. The check looks for six signals: a link to an About or author page, contact details (e-mail, phone or a contact page), Person schema, a privacy policy link, terms and conditions, and an address or company ID. Four or more signals mean the check passes. This relates to E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness).
