E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness. It is a framework from Google quality rater guidelines, not a ranking factor.
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness. It comes from Google’s Search Quality Rater Guidelines, the document Google pays people to assess search results by hand.
Say this part plainly, because a lot of writing on the subject does not: E-E-A-T is not a ranking factor. The algorithm has no E-E-A-T score. Raters do not influence the pages they score. Google uses their ratings to judge whether changes to the ranking systems made results better or worse. The framework describes what Google is aiming for, not a switch you can flip.
That does not make it useless. It is the clearest published statement of what Google wants its systems to reward, and the signals behind it are real even though the acronym is not.
What the four parts mean
Experience is first-hand involvement. Have you actually used the product, visited the place, done the procedure? Google added this E in December 2022, and the timing was not an accident: it arrived as generative AI made it trivial to produce competent writing by someone who has never touched the subject.
Expertise is knowledge and skill in the field. It means something different by topic. Medical content needs credentials. A review of a running shoe needs somebody who has run in it for 200 miles.
Authoritativeness is reputation. Do other people in the field treat you as a source? This is where citations, coverage and mentions do their work.
Trustworthiness is the one Google calls the most important of the four. Accurate information, transparent ownership, secure transactions, a real address, a way to reach a human. The other three feed into it.
Where it matters most
The guidelines apply the highest standard to Your Money or Your Life topics: health, finance, legal, safety, major life decisions. Bad information on those pages can cause real damage, so the bar for who should be publishing them is higher. A page about choosing a mortgage is held to a standard a page about houseplants is not.
What to actually do
Nothing here is exotic. Put real authors on articles with credentials that explain why they are qualified, and link the bio to somewhere that verifies it. Write in enough detail that the first-hand experience is obvious: specific numbers, things that went wrong, decisions you would make differently. Cite primary sources rather than other people’s summaries. Make your About, Contact and Editorial Policy pages complete. Date your content and correct it when it goes out of date.
Most of this is reputation work rather than page work, which is why it overlaps so heavily with digital PR. If you want it handled as part of a wider programme, our AI SEO service covers it.
Why it matters more for AI search
AI Overviews, ChatGPT and Perplexity all have to decide which sources to trust and name. They lean on entity recognition and on corroboration: whether the same claim, attached to the same named person or business, shows up consistently across sources they already rate. Clear authorship, a consistent brand entity and independent coverage all feed that. The mechanics differ from Google’s ranking systems, but the inputs look a lot like E-E-A-T.

Common questions
Can I measure my E-E-A-T?
No. There is no score, and any tool offering one has invented it. You can measure the things underneath it: branded search volume, referring domains from relevant publications, review counts and how often you are cited.
Does AI-written content break E-E-A-T?
Not by itself. Google says it judges the quality of what was made, not how it was made. What fails is content with no first-hand experience and nobody accountable for it, which is the usual output when AI writes unsupervised.
How long does it take to improve?
Months. On-page changes like author bios and citations can go live in a week, but the reputation half depends on other people writing about you, and that accumulates slowly.
