E-E-A-T (Experience, Expertise, Authoritativeness, Trust) is the set of four signals Google and AI search use to decide whether your site can be trusted: the author's first-hand experience, their expertise, the site's authority, and overall trust in it.
What each letter means
Experience - does the author have real, hands-on experience with the topic.
Expertise - do they have enough knowledge and qualifications.
Authoritativeness - are the site and author recognised in their field.
Trust - is the site safe and transparent. This is the key letter - without trust, the rest does not count.
Why it matters
Google uses E-E-A-T to tell quality content from shallow content. It is especially strict for health, finance and safety topics (so-called YMYL pages, where bad advice can cause harm). A site without trust signals loses to competitors even when the text is good.
How it ties into AI search
ChatGPT, Perplexity and other AI systems also rely on trust signals when deciding which source to cite. A site with weak E-E-A-T shows up in AI answers less often - and that is a growing traffic channel many still overlook.
Common mistakes
No author information or stated qualifications
Missing About and Contact pages
No links to sources or proof of real experience
No HTTPS, privacy policy or clear contacts - the site is not trusted

E-E-A-T is not a single numeric ranking factor but a set of signals Google weighs together. In practice, sites with strong E-E-A-T rank noticeably better, especially in competitive and YMYL niches.
How fast can I improve E-E-A-T?
Start simple: add authors with real credentials, an About page, contacts, HTTPS and source links. These basics can be fixed in a day - and a free audit shows exactly what is missing.
