Trustworthiness (E-E-A-T)
Last updated
What is Trustworthiness (E-E-A-T)?
Trustworthiness is the central pillar of E-E-A-T and refers to the overall reliability, honesty, and safety of a website and its content. Google's Quality Raters assess trust through signals such as accurate information, transparent authorship, clear disclosure of commercial relationships, secure HTTPS connections, accessible contact information, and a positive reputation outside of the site itself.
Sites that publish misleading information, hide their ownership, use deceptive design patterns, or lack basic transparency signals score poorly on trustworthiness. For e-commerce sites, customer reviews, clear return policies, and secure payment signals all contribute. Trustworthiness is considered the most critical of the E-E-A-T dimensions.
Why it matters for SEO
Google's quality rater guidelines describe trust as the most important element of E-E-A-T. Sites that fail basic trust signals, such as transparent ownership, accurate content, HTTPS and visible contact details, are rated poorly in quality evaluations, which makes trustworthiness a prerequisite for competitive rankings on any topic.
Example
An online supplement store shows its registered company name and address, a phone number and a clear returns policy, cites clinical sources for each health claim, and discloses its affiliate links. A competing store with anonymous ownership, no returns information and "miracle cure" claims fails basic trust checks, however well its pages are optimized otherwise.
