SEO Content: E-E-A-T Signals

Guides E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) implementation for SEO. E-E-A-T helps search engines and users assess content quality; YMYL topics (health, finance, legal) require higher E-E-A-T.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

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.

Output Format

E-E-A-T assessment (gaps, strengths)
Author bio recommendation
Citation plan (where to add, what to cite)
Experience signals (case studies, original data)
YMYL considerations (if applicable)
