What Is E-E-A-T

Element	Meaning	Implementation
Experience	First-hand, real-world experience	Case studies, original research, user testimonials, "we tested"
Expertise	Subject-matter knowledge	Author credentials, expert quotes, technical depth
Authoritativeness	Recognition as a source	Backlinks, citations, author page, publisher reputation
Trustworthiness	Accuracy, transparency	Citations, About page, contact, HTTPS, no misleading content

E-A-T (without Experience) is used in Featured Snippet context—Bing/Google emphasize correctness, document quality, then authority and trust. See featured-snippet.

Author Bio

Components

Element	Guideline
Real name	Full name used consistently across platforms
Photo	Professional headshot; compress for LCP
Credentials	Current role, relevant experience tied to article topic
Verifiable links	LinkedIn, personal site; align `sameAs` in Person schema
Author page	Dedicated page per author; bio, other articles, social
Lightweight action (optional)	Newsletter signup, social follow — avoid link stacking

Placement

End of article (default): User finishes reading, naturally curious about author; standard for blogs and deep content.
Top of article: Strong expert endorsement; suited for news, YMYL, or short items.
Sidebar (desktop): Compact version. Mobile fallback required — sidebar content often disappears on small screens; place author block within the main content column at the bottom on mobile.

Multi-Author

For co-authored, reviewed, or fact-checked content, list multiple author cards or label roles consistently (e.g. "Written by / Reviewed by").

Schema

Author entity uses Person JSON-LD with name, url, image, jobTitle, worksFor, knowsAbout, sameAs. Must match visible page content — no exaggeration or fabricated credentials. Validate with Rich Results Test. See entity-seo, schema-markup.

Citations & References

Scenario	Practice
Data or statistics	Cite source inline or in References section
Expert quotes	Attribute; link to source or profile
Reference section	For 5+ citations; list at end before Related posts
Format	Inline links preferred; numbered refs for academic-style
When to include	Any claim benefiting from authority (stats, studies, definitions)
External links	Link to reputable sources; avoid low-quality sites

Experience Signals

Signal	Use
Case studies	Real customer outcomes; Challenge→Solution→Results
Original research	First-party data, surveys, tests
First-hand testing	"We tested X"; product reviews with real use
User testimonials	Authentic quotes; link to full case study when available

YMYL (Your Money Your Life)

Topics that can significantly impact health, financial stability, or safety require higher E-E-A-T:

Health: Medical, mental health, nutrition advice
Finance: Investment, tax, insurance, loans
Legal: Legal advice, regulations
Safety: Product safety, emergency procedures

Guidelines: Author credentials, citations to authoritative sources, clear sourcing, regular updates, avoid speculation.

AI-Assisted Content

When content is AI-assisted: human review before publish; verify facts and add citations; original insights or data; avoid generic phrasing. Transparency and human refinement support E-E-A-T.
