Author Credentials: Building E-E-A-T Signals AI Can Verify

Author credentials for AI search consist of five verifiable components: visible byline, author bio (30+ words), Person schema markup, professional credentials, and sameAs links to verified profiles. This is checkpoint R02 in the GEO CORE model, contributing 25% to your overall reliability score. Content with complete author credentials is 1.8x more likely to be cited by AI systems than anonymous content.
These signals align directly with Google's E-E-A-T guidelines, which emphasize that content should demonstrate “who is responsible for the content” and “who created the content and their expertise.” AI systems use author signals to evaluate whether the content creator is qualified to make authoritative claims.
Key Takeaways
- ✓ Byline: Author name visible at top of article (10 points)
- ✓ Bio: 30+ word expertise description (10 points)
- ✓ Schema: Person markup with jobTitle and sameAs (10 points)
- ✓ Credentials: Titles, certifications, experience (bonus points)
The Five Author Credential Components #
1. Visible Byline #
A byline is the author's name displayed prominently on the page. AI systems look for this as the most basic author signal.
Weak Byline
“By Admin”
“Staff Writer”
No author attribution
No individual to verify
Strong Byline
“By Sarah Chen, SEO Director”
“Written by Dr. Michael Torres”
Name linked to author page
Verifiable individual
2. Author Bio #
The author bio should be at least 30 words and describe the author's relevant expertise.
Author Bio Template
[Name] is a [title/role] with [X years] of experience in [field]. They specialize in [specific expertise areas] and have [achievement/credential]. [Name] has [additional social proof - publications, speaking, awards].
Bio Must-Haves (30+ words)
- Full name
- Current title or role
- Years of experience
- Areas of expertise
- At least one credential or achievement
3. Person Schema Markup #
Schema markup helps AI systems understand and verify author information programmatically.
{
"@type": "Person",
"name": "Sarah Chen",
"jobTitle": "SEO Director",
"url": "https://example.com/team/sarah-chen",
"sameAs": [
"https://linkedin.com/in/sarah-chen",
"https://twitter.com/sarahchen"
],
"description": "SEO specialist with 10 years of experience..."
}4. Professional Credentials #
Credentials provide evidence of formal expertise. These are particularly important for YMYL (Your Money Your Life) topics.
| Credential Type | Examples | Impact |
|---|---|---|
| Academic | Ph.D., MBA, M.S., relevant degrees | High |
| Professional | CPA, MD, JD, PE licenses | High |
| Industry Certifications | Google certifications, HubSpot, AWS | Medium |
| Experience | “10+ years as [role]” | Medium |
| Publications | Books, journals, major publications | High |
5. sameAs Verification Links #
sameAs links connect the author to verified external profiles, allowing AI to cross-reference identity.
Recommended sameAs Links
- LinkedIn profile (professional verification)
- Company “About” or team page
- Twitter/X for industry presence
- Personal website or portfolio
- Google Scholar (for academic credentials)
