E-E-A-T

Also known as: Experience Expertise Authoritativeness Trustworthiness / 経験・専門性・権威性・信頼性

Google's four-factor quality framework: Experience, Expertise, Authoritativeness, and Trustworthiness. It guides both human quality raters and informs how Google's ranking systems assess content credibility.


Overview

E-E-A-T is defined in Google's Search Quality Evaluator Guidelines. The 'Experience' dimension was added in 2022, expanding E-A-T. Weight is especially high for YMYL (Your Money or Your Life) topics such as health, finance, and legal.

How to Improve E-E-A-T

Effective tactics include enriching author profiles with credentials and first-hand experience, earning backlinks from authoritative sources, and adding Schema.org Person/Organization markup. See our SEO site design guide for a practical checklist.
