What E-E-A-T Is (And Isn't)
E-E-A-T - Experience, Expertise, Authoritativeness, and Trustworthiness - comes from Google's Search Quality Evaluator Guidelines: the handbook used by thousands of human quality raters to assess search results.
It is not a direct algorithm. Google's quality raters don't adjust rankings in real time. Instead, E-E-A-T describes the characteristics that Google's algorithm is designed to reward - the guidelines inform the algorithm's training targets.
The distinction matters because it tells you that E-E-A-T signals are real and measurable, but you can't game them with a single tactic. They're the cumulative result of how your site and content present themselves over time.
The Four Components
Experience (added in late 2022, hence E-E-A-T rather than E-A-T) refers to first-hand experience with the topic. A product review written by someone who actually used the product has experience signals. A listicle assembled from other listicles does not.
Expertise is demonstrable subject-matter knowledge. This is domain-specific. A medical article needs to be written by a qualified healthcare professional. A web design article needs to reflect real practitioner knowledge. Generic, hedged, surface-level content signals low expertise.
Authoritativeness is the reputation of the creator and site within their field. It's built through recognition from peers: citations, mentions in industry publications, speaker credits, links from authoritative sources. It cannot be claimed - only earned.
Trustworthiness is the foundation of the framework. A site that is technically an expert but that uses deceptive patterns, has no privacy policy, or has a history of misleading users fails on Trust - which overrides the other signals.
YMYL: Where E-E-A-T Matters Most
E-E-A-T is applied most strictly to YMYL content - Your Money or Your Life. Queries where low-quality information could directly harm a user's health, finances, safety, or welfare.
Medical, legal, financial, and safety topics require the highest levels of demonstrated expertise. A personal finance blog written by anonymous authors with no credentials will not rank for YMYL queries, regardless of other optimisation.
Building E-E-A-T Signals
Author bios. Every article should have a named, credentialed author. The author page should include professional background, published work, and verifiable credentials. Author schema markup connects the article to the author's recognised entity.
About page. Google's quality raters check the About page. It should clearly explain who you are, your qualifications, and why you're credible on the topics you cover.
Cite authoritative sources. Link out to primary sources: peer-reviewed research, government data, authoritative industry bodies. This demonstrates that your content is grounded in verified information.
Earn coverage. Being cited by, or quoted in, authoritative publications is the most powerful E-E-A-T signal because it's external validation. This is built through digital PR, original research, and consistent credible publishing over time.
Maintain factual accuracy. Update outdated statistics and claims. Date-stamp content. Correct errors promptly and transparently. A track record of accuracy is the foundation of trust.
