E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It is the quality framework Google's human quality raters use to score content, and it shapes which pages the algorithm rewards with sustained rankings and AI overview citations. Content that cannot demonstrate real first-hand experience and verifiable expertise fails the framework, regardless of how well it is optimised technically.
Experience was added to the original E-A-T framework in December 2022, and it is the hardest signal to fake. It asks: does the author or site have first-hand experience with the topic? A review written by someone who has actually used the product, or a how-to written by someone who has done the thing, carries genuine experience signals. Machine-generated summaries of other pages do not.
Expertise is the depth of knowledge demonstrated in the content itself. For medical, legal, and financial topics (Google calls these YMYL: Your Money or Your Life), expertise must be demonstrable and attributed. For other topics, expertise is shown through accuracy, specificity, and the absence of hedging filler.
Authoritativeness is largely an off-page signal: third-party mentions, citations, and links from recognised sources. It is built over time and reflects whether the wider web treats your site as a credible source in its field.
Trustworthiness is the overarching signal. Google's quality rater guidelines describe Trust as the most important of the four. It encompasses accurate information, clear attribution, honest handling of limitations and caveats, and transparent ownership of the site.
AI overviews and other generative answer features draw preferentially from content that meets high E-E-A-T standards. A model that is synthesising an answer from multiple sources will tend to quote the passage with the most credible, specific, and experience-grounded claim. Thin or anonymously authored content is both less likely to rank and less likely to be cited. Building E-E-A-T into your content process is the same investment that builds citation share.
