What is E-E-A-T?

最終更新 2026-07-03

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It is the framework Google uses to judge content quality, and the same signals help AI systems decide which sources to trust and cite. Strong E-E-A-T makes a page more likely to be retrieved and quoted in an AI answer.

Why E-E-A-T matters for AI answers

AI systems favor sources that look credible: first-hand experience, demonstrated expertise, recognized authority, and clear trust signals. A page that answers a question directly but comes from a low-trust domain is less likely to be cited than the same answer from an authoritative one.

How to strengthen E-E-A-T

  • Show real experience and named, credentialed authors
  • Earn links and mentions from recognized sources
  • Keep facts accurate, current, and clearly sourced
  • Make the page transparent about who is behind it
