E-E-A-T stands for experience, expertise, authoritativeness and trust. It is the framework Google's search quality raters use to judge whether a page deserves to be believed, and it is one of the most misread ideas in SEO, mostly because people treat it as a score to be raised. Google's own SEO starter guide lists "Thinking E-E-A-T is a ranking factor" among the things not to focus on, and answers it in three words: "No, it's not." This guide explains what each part means in Google's own words, what the framework is for, and what you can change on a page to make it more trustworthy to the person reading it, which is the only version of E-E-A-T worth working on.

Where E-E-A-T comes from

The term lives in Google's Search Quality Evaluator Guidelines, a long public document written for the people who rate search results for Google. The edition we read for this guide is dated 11 September 2025. Raters look at real queries and real results and judge how good they are; Google uses those judgements to check whether changes to its systems are working.

The guidelines are blunt that raters do not move pages around: "No single rating can directly impact how a particular webpage, website, or result appears in Google Search". Google's page on creating helpful content says the same thing more plainly, "Search raters have no control over how pages rank", and compares rater feedback to the feedback cards a restaurant might get from diners.

The framework used to be E-A-T. On 15 December 2022 Google's Search Central blog announced that it was "gaining an E: experience", asking whether content shows it was produced by someone with actual use of a product, a visit to a place, or first-hand knowledge of what they describe. The post's example is useful: if you need to fill in a tax return correctly you probably want an accountant, but if you want to know which tax software is pleasant to use, a forum thread from people who have used several may serve you better.

Is E-E-A-T a ranking factor?

Not as a single measurable thing. The precise position, from the helpful content page, is this: "While E-E-A-T itself isn't a specific ranking factor, using a mix of factors that can identify content with good E-E-A-T is useful." The same page says Google's systems give "even more weight" to content aligned with strong E-E-A-T on topics that could significantly affect people's health, financial stability or safety, or the welfare of society.

So there is no E-E-A-T score to raise, no tag to add and no plugin that supplies it. What exists is a description of what a trustworthy page looks like, and a set of automated signals Google uses to approximate it. Writing for the description is a better use of time than guessing at the signals.

The four parts, in Google's words

The rater guidelines put trust in the middle: "The most important member at the center of the E-E-A-T family is Trust." Trust is defined as the extent to which "the page is accurate, honest, safe, and reliable." The other three are described as concepts that support an assessment of trust:

  1. Experience. Whether the creator has the first-hand or life experience the topic needs. The guidelines ask which you would trust: a product review from someone who has used the product, or a "review" from someone who has not.
  2. Expertise. Whether the creator has the knowledge or skill the topic needs. The example is home rewiring advice from a skilled electrician compared with the same advice from an enthusiast for old houses who knows nothing about wiring.
  3. Authoritativeness. Whether the creator or website is known as a go-to source for the topic. Most topics have no single official source, but some do: the guidelines point out that the official government page for getting a passport is the authoritative source for passport renewal.
  4. Trust. The one that decides the rest. The guidelines say "untrustworthy pages have low E-E-A-T no matter how Experienced, Expert, or Authoritative they may seem", and use a financial scam run by a highly experienced scammer as the example.

Not every page needs all four

The helpful content page notes that the components contribute to trust but "content doesn't necessarily have to demonstrate all of them". A page can be helpful because of the experience behind it, or because of the expertise it shares.

How much trust a page needs depends on what could go wrong. The guidelines call the high-stakes topics "Your Money or Your Life", or YMYL: topics that could significantly affect people's health, financial stability or safety, or the welfare or well-being of society. They also say that many or most topics are not YMYL. A light social post on a harmless subject does not need the trust a page about medication does.

Within YMYL topics, the guidelines draw a useful line between experience and expertise. Safe, non-medical tips from people who have struggled to sleep late in pregnancy are given as valuable life experience; which sleep medications are safe in pregnancy is listed as information best left to experts. In the same way, reviews of retirement saving services by people who have used them count as experience, while advice on how much to save and what to invest in belongs to experts.

How raters look for it

Raters are told to inform their assessment from one or more of three places:

  1. What the site or creator says about itself, starting with the About page or the author's profile.
  2. What others say about the site or creator, through independent reviews, references and news coverage.
  3. What is visible on the page itself, including the main content and any reviews or comments. Sometimes expertise is obvious from the work, such as a video of a hairdresser actually styling hair.

The guidelines also flag conflicts of interest. A review by someone who owns a product and shares their experience can be valuable; a "review" by the manufacturer, or by an influencer paid to promote the product, is less trustworthy for that reason.

What to do on your own pages

None of the following is a trick. Each one makes the page more believable to a reader, which is the point.

  1. Say who wrote it. Google's guidance says: "We strongly encourage adding accurate authorship information, such as bylines to content where readers might expect it." Link the byline to a page that says who the author is and what they write about.
  2. Never invent an author. The same page calls fabricated creator profiles, such as AI-generated headshots, made-up names or false credentials, "a form of deception", and says any deception makes a page untrustworthy.
  3. Put the experience in the text. If you tested something, say what you tested, how, and what happened. For product reviews, Google suggests showing the number of products tested, the results, how the tests were run, and evidence such as photographs.
  4. Cite primary sources for every claim you did not witness yourself. Link to them, and check that they say what you say they say. The fact-checking routine covers this step by step.
  5. Declare conflicts of interest. If you sell the thing you are comparing, or were paid to write about it, say so near the top.
  6. Know when you are in YMYL territory. If the page gives advice that could cost someone money or health, either have a qualified person write or review it, or limit the page to experience you can honestly report.
  7. Explain how the content was made when readers would wonder. Google suggests disclosing automation or AI involvement where it would reasonably be expected; our piece on AI-generated content and Google Search goes into what that means in practice.

What E-E-A-T will not fix

A byline does not make an inaccurate page accurate, and an author bio does not make a page answer the question someone searched for. The guidelines are explicit: "If a page is untrustworthy for any reason, it has low E-E-A-T." The trust comes from the page being right, honest about its limits and clear about who stands behind it. If the page also misreads what the searcher wanted, no amount of credentials will rescue it; that is a separate problem, covered in our guide to search intent.
