Trust in EEAT: The Foundation of AI Content Evaluation
Trust is the foundation of E-E-A-T—the ultimate test of whether a website is safe to recommend. While Experience, Expertise, and Authority establish what you know and who recognizes it, Trust determines whether readers and AI can rely on you. Google explicitly states Trust is “the most important member of the E-E-A-T family.” AI evaluates trust through six key signals: legal compliance, contact information, security, ad density, content maintenance, and transparency disclosures.
Key Takeaways
- • Trust is the most important EEAT element—per Google's guidelines
- • 6 trust signals: Legal, contact, security, ads, maintenance, disclosure
- • Trust issues can override other signals—expertise doesn't matter if users can't trust you
- • Many trust signals are binary—you have them or you don't
- • Transparency builds trust—clear disclosure of relationships and methodologies
Why Trust is the Foundation #
Google's Quality Rater Guidelines explicitly state: “Trust is the most important member of the E-E-A-T family because untrustworthy pages have low E-E-A-T no matter how Experienced, Expert, or Authoritative they may seem.”
Consider: A medical site with expert doctors (Expertise), recognized by the industry (Authority), with real patient experience (Experience)—but also with data breaches, misleading ads, and hidden affiliate relationships. Despite strong EEA, the Trust deficit makes it unreliable.
Trust as a Multiplier
Think of Trust as a multiplier on other EEAT signals. High trust amplifies expertise and authority. Low trust diminishes or negates them entirely.
The 6 Trust Signals AI Evaluates #
T01: Legal Compliance #
Required legal pages that demonstrate legitimate business operation:
- Privacy Policy: How you handle user data
- Terms of Service: Usage conditions and disclaimers
- Cookie consent: GDPR/CCPA compliance
- Disclaimers: YMYL-appropriate risk disclosures
Missing legal pages suggest either negligence or deliberate opacity—both reduce trust.
T02: Contact Information #
Verifiable ways to reach the people behind the content:
- Physical address: Business location (if applicable)
- Email contact: Reachable email address
- Phone number: For businesses serving customers
- Contact forms: Working contact mechanisms
Sites without contact information feel anonymous and unaccountable—major trust red flags.
T03: Security #
Technical security that protects users:
- HTTPS: Encrypted connection (mandatory)
- Valid SSL certificate: Properly issued and current
- No mixed content: All resources loaded securely
HTTP-only sites are increasingly penalized. Mixed content warnings damage trust.
T04: Ad Density #
Balanced advertising that doesn't compromise user experience:
- Reasonable ad volume: Ads don't overwhelm content
- Clear separation: Ads distinguishable from content
- No deceptive ads: No misleading ad placements
- Mobile-friendly: Ads don't break mobile experience
Sites drowning in ads signal prioritization of revenue over user value.
T05: Content Maintenance #
Signs that content is maintained and kept current:
- Working links: No 404s or broken external links
- Updated content: Information is current
- Active site: Recent publication dates
- Accurate dates: Last updated visible
Abandoned sites with outdated information and broken links aren't trustworthy resources.
T06: Disclosure and Transparency #
Clear disclosure of relationships and methodologies:
- Affiliate disclosure: Clear indication of affiliate relationships
- Sponsorship disclosure: Sponsored content labeled
- Methodology disclosure: How recommendations are made
- Risk warnings: Appropriate warnings for YMYL content
Hidden commercial relationships undermine trust. Transparency builds it.
Trust Audit Checklist #
Review your site against these trust elements:
| Signal | Required Element | Status |
|---|---|---|
| Legal | Privacy Policy, Terms of Service | □ Present □ Missing |
| Contact | Email, Contact Form, Address (if applicable) | □ Present □ Missing |
| Security | HTTPS, Valid SSL | □ Present □ Missing |
| Ads | Reasonable density, clear separation | □ Good □ Excessive |
| Maintenance | No broken links, updated content | □ Maintained □ Neglected |
| Disclosure | Affiliate/sponsor disclosure where needed | □ Disclosed □ Hidden |
Trust Requirements for YMYL Content #
YMYL (Your Money or Your Life) content faces heightened trust scrutiny:
- Health content: Medical disclaimers, expert review, current information
- Financial content: Regulatory disclosures, risk warnings, credentials
- Legal content: Jurisdiction notices, professional disclaimers
- Safety content: Accurate warnings, current guidelines
For YMYL topics, trust isn't optional—it's the primary evaluation criterion.
Summary #
Trust is the foundation of EEAT:
- Legal compliance: Privacy policy, terms, cookie consent
- Contact information: Verifiable ways to reach you
- Security: HTTPS and valid SSL
- Ad density: Ads don't overwhelm content
- Content maintenance: Working links, current information
- Disclosure: Transparent about relationships and methods
Without trust, expertise and authority don't matter. Build trust first.
