E-E-A-T
Google's quality framework: Experience, Expertise, Authoritativeness, Trustworthiness.
E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is Google's framework for evaluating content quality, used by human raters and encoded into ranking signals. The "Experience" dimension was added in December 2022 to emphasize first-hand experience with a topic.
E-E-A-T matters for AEO because AI engines (including Google's AI Overviews) use similar quality signals. Content with clear author credentials, citations, and demonstrated expertise is cited more often.
