E-E-A-T and Security: Building Trust Signals That Rank

What Is E-E-A-T?

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It comes from Google's Search Quality Rater Guidelines. A 170-page document used by human raters to evaluate search result quality. While rater scores don't directly influence rankings, they calibrate the algorithms that do.

• Experience. Does the creator have first-hand experience with the topic?
• Expertise. Does the creator have formal knowledge or skill?
• Authoritativeness. Is the creator or site recognized as a go-to source?
• Trustworthiness. Is the page accurate, honest, safe, and reliable?

Trust Is the Foundation

Google's guidelines explicitly state that Trust is the most important member of the E-E-A-T family. A page can have high experience and expertise, but if it's not trustworthy, E-E-A-T is low overall. An HTTP site with no privacy policy selling products. Low trust, regardless of how expert the content is.

Trust is evaluated differently for different page types. For YMYL pages (Your Money or Your Life. Health, finance, safety), Trust requirements are highest. An e-commerce site without HTTPS is a trust failure. A health advice page without author credentials is a trust failure.

Security as a Trust Signal

Security measures that directly contribute to Trust evaluation:

• HTTPS. The baseline. No HTTPS means automatic "Not Secure" label in Chrome.
• Valid TLS certificate. No expired, self-signed, or domain-mismatched certificates.
• Security headers. CSP, HSTS, X-Frame-Options protect users from attacks.
• No malware or phishing. Clean Safe Browsing status.
• Secure forms. Login and payment forms use HTTPS, have CSRF protection.
• Cookie security. HttpOnly, Secure, SameSite flags on session cookies.

Building Trust Signals

Beyond technical security, these signals contribute to Trust:

1. Privacy policy. Required by GDPR for EU visitors. Expected by Google for any site collecting data. Link it from every page footer.
2. Contact page. Real contact information. A physical address, email, and phone number. Not a generic form with no response.
3. About page. Who runs the site? What are their qualifications? Include real names and credentials for YMYL content.
4. Author attribution. Bylines on articles with author bios. Link to author profiles on LinkedIn or professional sites.
5. Terms of service. Especially for e-commerce and SaaS.
6. Clear sourcing. Link to sources. Cite research. Don't make claims without backing them up.
7. No deceptive practices. No fake urgency, misleading claims, or hidden costs.

Schema Markup for Trust

Structured data helps search engines understand your site's identity and trustworthiness. Key schemas from Schema.org:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Company",
  "url": "https://yoursite.com",
  "logo": "https://yoursite.com/logo.png",
  "contactPoint": {
    "@type": "ContactPoint",
    "email": "contact@yoursite.com",
    "contactType": "customer service"
  }
}

For articles, use Article schema with author, datePublished, and dateModified. This helps Google attribute content to real people and understand when it was last updated.
