E-E-A-T: Experience, Expertise, Authority, Trust
E-E-A-T stands for experience, expertise, authoritativeness and trust: the frame Google's raters use to judge page quality. It is not a tag, not a number in a report and not a ranking factor. But it shows which pages Search tries to treat as reliable — and it is a convenient way to check your own.
We work from two primary sources: the quality rater guidelines and Google's note on adding the second E. What follows from them for an ordinary site is in the helpful content guidance.
E-E-A-T means Experience, Expertise, Authoritativeness, and Trust. It is not a tag, not a report score, and not a secret ranking coefficient. It is a quality framework: how a page proves it deserves trust.
What E-E-A-T really is
Google employs raters — real people who assess the quality of results against a detailed manual. Their ratings do not move an individual page: they show how well the ranking systems work overall. Google states it plainly — the guidelines are used by raters to evaluate the systems and do not directly influence ranking.
Which leads to a practical conclusion: E-E-A-T cannot be improved with settings. What you can do is make the page one where a first-time reader understands who wrote it, how they know this, and why they can be believed.
The four letters without magic
| Letter | What it means | How to show it on the page |
|---|---|---|
| Experience | The author or company has actually dealt with the subject. | Photographs, cases, screenshots, measurements, an account of your own mistake, data from practice. |
| Expertise | The author has knowledge or qualifications in the subject. | A bio, a role, relevant training, review by a specialist where it matters. |
| Authoritativeness | Others treat the site or author as a source that counts. | Mentions, links, citations, talks, a recognisable brand. |
| Trust | The page can be safely relied on. | Accurate facts, visible contacts, payment and refund terms, sources for claims, no overstatement. |
The first two are the ones people confuse, and Google explains the difference with an example of its own: to fill in a tax return correctly you want material from an accounting expert — that is expertise. To choose the software for preparing that return, a discussion among people who actually used it is more useful — that is experience. Both are valuable, on different queries.
The glossary covers the terms: E-E-A-T and author authority.
Trust sits at the centre
Of the four letters, trust outweighs the rest, and the rater guidelines say so directly: an untrustworthy page has low E-E-A-T however experienced, expert or authoritative its author may seem.
What that means for an ordinary site: first remove what undermines trust, then build expertise. A hidden author, inaccurate facts, promises without caveats, missing contacts, advertising dressed as advice — each of those devalues any qualification.
What trust consists of depends on the topic. For a shop it is the seller's details, payment, delivery and refund terms, genuine reviews. For a medical article, a qualified author, review, an update date and careful wording. For an SEO lesson, examples, links to primary sources, and honesty where there is no exact answer.
YMYL: where a mistake costs more
YMYL stands for Your Money or Your Life. The guidelines define such topics not by industry but by the kind of harm: a topic is YMYL if the content could significantly impact the health, financial stability or safety of people, or the welfare of society.
That distinction matters more than it looks. "Medicine" is not automatically YMYL, but a home remedy for chest pain is. And the other way round: a page about choosing a child car seat does not look medical, and a mistake on it costs dearly.
| Topic | What the reader expects |
|---|---|
| Health | A qualified author or reviewer, an update date, links to reliable sources, a reminder to consult someone. |
| Finance | Risks stated plainly, careful arithmetic, no promises of guaranteed returns. |
| Law | The jurisdiction named, a currency date, a note that this does not replace advice. |
| Shopping | Seller details, payment and refund terms, genuine reviews, payment protection. |
The easiest test for whether your topic belongs here: what happens to a person who believes the page and the page is wrong? Who the raters are and what they do is in the glossary: search quality raters.
Strong E-E-A-T in Content
- The author is visible. The article has a name, role, short bio, and author page.
- Experience is proven. The page includes observations, measurements, cases, mistakes, photos, screenshots, or real conclusions.
- Facts are verifiable. Numbers, legal claims, medical claims, and studies can be checked.
- The page is maintained. For topics that change, update dates and review logic are visible.
- The site is transparent. Contacts, About page, privacy policy, editorial policy, or review process are visible.
- Reputation exists beyond the site. External sources, industry sites, customers, and partners mention the brand or author.
Common Mistakes
| Mistake | Why it is weak | Better approach |
|---|---|---|
| Adding "Author: Admin" | A name without competence does not prove expertise. | Show a real author, experience, specialization, and responsibility. |
| Publishing long AI text without examples | Length is not experience. AI often summarizes what already exists. | Add own observations, data, cases, comparisons, and limitations. |
| Hiding contacts and terms | Users do not know who receives their money or data. | Make contacts, company details, payment/return terms, and policies visible. |
| Being overconfident in YMYL | Dangerous advice can harm users. | Use experts, disclaimers, evidence, update dates, and careful wording. |
How to think about E-E-A-T in an audit
"Does this page have E-E-A-T" is a meaningless question: it is not something a page has or lacks. Six specific ones are more useful:
- Who made this page, and why should they be believed?
- Is there experience of your own here, or only a retelling of other articles?
- Can the important claims be checked — do they carry a source and a date?
- Is it clear who owns the site and how to reach them?
- Does this topic need ordinary experience, or a specialist?
- What on the page reduces trust: errors, aggressive promises, stale dates, advertising in disguise?
These echo what Google suggests asking of your own material in the helpful content guidance — there are more of them there, and it is worth reading in full.
Some of the answers are visible through tools: the page analyzer shows structure and metadata, the text quality check the share of generalities, and the generation-signal check where the text went flat. The author name and update date can be mirrored in markup: the fields are in the Article schema.
Practice: check one of your own pages
Take a page a reader might act on — buy something, choose something, do something. Five steps:
- Open it as if you had never seen the site. Can you say within half a minute who wrote this and what they do? If not, that is the first thing to fix.
- Find the three strongest claims in the text. Does each have a source, a date, or your own data? Claims with nothing behind them are candidates for removal or verification.
- Ask: what happens to a person who believes this page and the page is wrong? If the answer is serious, the topic is YMYL and the bar is higher.
- Walk the site as a customer: are the contacts, terms and the responsible party findable? The site audit gives the whole-site view.
- A month later, check what changed for that page in the performance report. The content decay finder tracks material that is going stale.
The glossary covers the terms: E-E-A-T, search quality raters, thin content, author authority.
How to tell you are working with E-E-A-T properly
The sign is that you stopped looking for where to switch it on. The question used to be "how do we raise our E-E-A-T"; now it is "what on this page stops a person believing it".
Three questions to check yourself. Can you name who is responsible for each piece on your site? Is there a single page where you deliberately wrote "there is no exact answer"? Have you removed even one claim in the past month because you could not back it?
What not to expect: that a byline changes anything on its own. It answers the "who" question, but with no experience and no checkable facts behind it, it only makes the emptiness easier to see.
