What is Author Bio?
Author Bio is the author block at article end — since 2024 a mandatory E-E-A-T and GEO signal. Elements: real name, photo, 3–5 line credentials, Person schema + sameAs to LinkedIn/X/Wikidata.
How do you apply it in practice?
AI engines check whether the Person entity can be verified on Wikidata/LinkedIn. Unverifiable = content discounted.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Author Bio" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.

E-E-A-T
E-E-A-T are the four quality signals from Google's Search Quality Rater Guidelines: Experience, Expertise, Authoritativeness, Trustworthiness. Trust is the foundation — without it, the other three count as zero.
Person Schema
Person Schema is the Schema.org JSON-LD type for real people: name, jobTitle, worksFor, knowsAbout, sameAs. The core structured signal Google Knowledge Panels and AI engines use to identify author entities.
YMYL (Your Money or Your Life)
YMYL covers topics that may affect a reader's finances, health, safety, or legal status. Google enforces the strictest E-E-A-T here: real bylined authors, credentials, verifiable sources. AI engines are also more conservative when citing YMYL content.
