E-E-A-T stands for experience, expertise, authoritativeness and trust. It comes from the guidelines Google gives the human beings who rate search results, and it is worth understanding precisely what that means.
It is not a number attached to your site. Nobody is computing your E-E-A-T. It is the description of what good looks like, which the rating data is then used to check the algorithm against. That distinction matters: you cannot optimise for a score that does not exist, but you can build the thing the score is trying to detect.
The extra E is the newest and the most useful
Experience was added to the front of the acronym, and it is the one that changes what you write.
Expertise is knowing about something. Experience is having done it. For a huge range of queries, the searcher wants the second: someone who has actually used the product, made the mistake, run the process, lived in the town. That is also the one thing a language model with no access to your life cannot manufacture.
In practice this means first-hand detail. What you tried, what it cost, what went wrong, what you would do differently. Those specifics are simultaneously the most useful part of a piece and the hardest part to fake.
What each letter looks like on an actual page
Abstract advice about being authoritative helps nobody. Here is what each one is, concretely.
- Experience: first-hand accounts, original photos, specific numbers from your own work, honest description of limits
- Expertise: an author with relevant background, named and credited, writing within that background
- Authoritativeness: other credible sites and people citing or quoting you on this topic
- Trust: clear contact details, honest pricing, visible policies, no hidden ownership, corrections when you get it wrong
Trust is the one that outranks the others
Google's own guidance says trust is the most important member of the family, and that the others exist mainly to support it.
That reframes the work. A page can be written by a genuine expert and still fail if the site around it hides who runs it, buries the price, or fills the margins with content that contradicts the article. Trust is a property of the whole site, and one page cannot rescue it.
Where it matters most
Google applies the highest standard to what it calls Your Money or Your Life topics: health, finance, safety, legal matters, and anything else where bad advice does real damage.
If you publish in those areas, the bar for named authors with verifiable credentials, cited sources and visible review dates is genuinely higher, and thin content is treated more harshly. If you publish on how to choose a coffee grinder, the bar is lower and first-hand experience carries proportionally more weight.
Author pages are not decoration
A byline that links nowhere does very little. An author page that establishes why this person is worth reading on this subject does quite a lot.
Include what they have actually done, not a list of adjectives. Link their professional profiles. Keep it consistent with what those profiles say. If a piece is written by a team or by AI with human editing, say so plainly. Inventing a person is a trust failure that is easy to discover and hard to recover from.
AI-written content and E-E-A-T
Google's position is that it rewards helpful content regardless of how it was produced, and that content produced primarily to game rankings is the problem, not the tool.
The practical consequence is specific. AI is good at structure, coverage and clarity, and it has no experience whatsoever. So the parts that need a person are the ones that carry the E: the example from your own work, the number from your own account, the opinion you would defend, the caveat you learned the hard way.
A workable division is to let a model handle the outline and the connective prose, then to put your actual experience into it, and to have someone who knows the subject check that every claim survives contact with reality.
A page-level checklist
Before publishing anything you want to rank on a competitive term, run through this.
- Is there at least one thing here that only someone who did this would know
- Is the author named, and is this within what they actually do
- Does every factual claim have a source, a number, or a stated basis
- Have you said who this is not for, and what it does not cover
- Would you be comfortable if the subject of the page read it
The short version
E-E-A-T is not a checklist to pass, it is a description of a site that deserves to be believed. The fastest route to it is to publish things you actually know, sign them with a real name, admit what you do not know, and make it easy to find out who you are.
Everything else in this guide is a way of proving that on a page. The proving is only necessary because so many sites are trying to fake it.
Common questions
- Is E-E-A-T a ranking factor?
- Not directly. It is the description given to human quality raters, whose judgements are used to check the algorithm rather than to score your site. Nobody is computing your E-E-A-T, so build the thing it describes rather than optimising for a number that does not exist.
- Does AI-written content hurt E-E-A-T?
- Not by itself. Google rewards helpful content regardless of production method. The risk is that a model has no experience, which is the one letter it cannot supply, so the first-hand parts have to come from a person.
- Which part of E-E-A-T matters most?
- Trust. Google's own guidance says the other three exist mainly to support it, which means clear ownership, honest pricing and visible policies matter as much as the credentials on a byline.
