Understanding it
The acronym comes from the guidelines Google gives its search quality raters, people who grade results to test the algorithms. It was E-A-T until December 2022, when Google added experience: having actually used the product, visited the place, lived the situation.
Google states that these ratings do not directly affect rankings. They are used to check that its systems surface useful, reliable content. E-E-A-T is therefore built through visible proof, not through a tag.
That proof is also what AI engines pick up on: named authors, cited sources, dated figures, real case studies, the brand’s presence elsewhere on the web. It matters even more on topics involving money or health.
A concrete example
Illustrative example: an insurance broker’s guide
A broker publishes a guide to fleet insurance. The first version, unsigned, lines up generalities found everywhere.
The revised version is signed by the broker, with their background and professional registration number. It cites the relevant legislation, illustrates each point with an anonymized case it handled, and shows its last update date. The substance has barely changed, the proof has become visible.
The common mistake
Adding an author bio and stopping there
An “about the author” box proves nothing if the text stays generic. Experience shows in the content itself: a specific case, a measurement, a photo taken on site, a clear opinion. The byline confirms, it does not replace.
