What are website trust signals?

Visible and machine-readable cues—bios, reviews, policies, certifications, contact info, and schema—that help users and AI systems believe your site is credible and safe.

Which trust signals should I add first?

Clear About/Contact pages, author bios with credentials, real reviews/testimonials, transparent policies (privacy, returns), and Organization/Person/LocalBusiness schema.

How do trust signals affect AI search?

Strong, consistent trust cues make AI assistants more likely to cite you and less likely to hallucinate or misattribute your content.

What matters most for YMYL sites?

Expert-reviewed content, credentials, disclaimers, authoritative sources, and up-to-date schema linking authors and organizations; avoid speculative claims.

How do I measure trust signal impact?

Monitor AI/assistant citations, engagement on trust-heavy pages, conversion rates, and reductions in bounce/exit after adding proofs and clarity.

How often should I audit trust signals?

Quarterly—check that policies, bios, reviews, and schema are current; test how assistants describe your brand and fix gaps.

How do I localize trust signals?

Translate policies and bios, use local reviews and addresses, ensure schema has correct locale data, and surface local certifications or registrations (e.g., VAT, company numbers).

Can digital PR help trust signals?

Yes—quality mentions and backlinks from trusted outlets reinforce your credibility and entity graph, improving trust with users and AI systems.
