E-E-A-T
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness — Google's framework for judging content quality, and a useful proxy for the credibility signals AI engines reward.
Also known as: EEAT, Experience Expertise Authoritativeness Trustworthiness
E-E-A-T is Google's shorthand for what makes content trustworthy. It bundles four signals — first-hand Experience, demonstrated Expertise, recognized Authoritativeness, and overall Trustworthiness — that human quality raters and ranking systems use to judge whether a page deserves to be surfaced, especially for high-stakes topics.
It matters for AEO because the same qualities make an answer engine comfortable citing you. Experience and expertise map to originality and credibility — first-hand insight and evidenced claims — while authoritativeness maps to authority, the off-site mentions and corroboration that show the web already trusts you. E-E-A-T isn't a score you can set; it's the accumulated result of named authors, real evidence, and a recognized reputation.
Example. A medical article written by a named, credentialed doctor, citing primary studies, on a site widely referenced elsewhere, exhibits strong E-E-A-T — and is exactly the kind of source an engine will both rank and cite over an anonymous, unsourced post.
