E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness — the framework from Google’s Search Quality Rater Guidelines used to assess the quality of a piece of content and the reliability of its source. It is not a direct ranking factor or a score; it is the lens human quality raters apply, which in turn guides how Google trains and tunes its ranking systems.
The first “E,” Experience, asks whether the creator has firsthand or life experience with the topic. Expertise covers depth of knowledge, Authoritativeness covers reputation and recognition as a go-to source, and Trustworthiness — which Google calls the most important member of the family — covers accuracy, honesty, safety, and transparency. The other three exist mainly to support Trust, which sits at the center of the framework.
E-E-A-T matters far beyond traditional rankings: the same signals of credible experience, expertise, and trust increasingly influence which sources get cited in AI answers, making it a foundation of Generative Engine Optimization. The full guide below covers how to demonstrate each element in practice.
