Google E-E-A-T: Experience, Expertise, Authoritativeness, Trust

Google E-E-A-T stands for Experience, Expertise, Authoritativeness and Trust. It is the criteria roughly 16,000 human quality raters use to judge page quality, described in Google's Search Quality Rater Guidelines. It is not a ranking factor and there is no E-E-A-T score. It describes the qualities Google builds its ranking systems to reward, which makes it a checklist for content rather than a dial in an algorithm.

What the four letters actually mean

Google defines each one narrowly, and the definitions are more useful than the acronym. The official overview of the Search Quality Rater Guidelines puts them like this.

The second E, Experience, was added in a December 2022 update to the rater guidelines, and it is the one that favors small operators. A roofer who has replaced 400 roofs in Livingston Parish has something a national content farm cannot manufacture, and Google has explicitly told its raters to look for it.

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

No, and the misunderstanding here causes real waste. There is no E-E-A-T score, and no rater ever sees your site and moves it up or down.

Google states it directly: "no single rating and no single rater directly impacts how a given page or site ranks in Search." The reasoning is practical. There are trillions of pages, humans could never rate them all, and a single human score would miss dimensions like spam, security and staleness that ranking depends on. Google says it uses aggregated ratings "to measure how well our systems are working" and to give those systems positive and negative examples.

Google makes the same point in its guidance on creating helpful, reliable, people-first content, where it compares rater data to a restaurant collecting feedback cards from diners: useful for knowing if the kitchen is working, not a per-table verdict.

The practical translation: you cannot optimize for E-E-A-T directly, and you can build the things E-E-A-T describes, which is what the ranking systems are aimed at approximating.

Trust is the one that matters most

If you only fix one of the four, fix this one. Google says so plainly.

In its helpful content guidance, Google writes: "Of these aspects, trust is most important. The others contribute to trust, but content doesn't necessarily have to demonstrate all of them." That is a hierarchy, not a list. Experience, expertise and authoritativeness are inputs to trust rather than parallel scores.

For a local business, trust is mostly unglamorous site hygiene that nobody enjoys doing: a real street address, a working phone number, HTTPS, an about page with faces, terms and refund policies that exist, prices that match what you charge, and reviews you did not buy. None of that requires a content strategy. Most sites that "have an E-E-A-T problem" have a contact page problem.

The page quality scale raters use

Raters score pages on how well they achieve their purpose, using five bands. Knowing the bands makes the guidelines much easier to apply to your own pages.

Google tells raters that main content is high quality "if it takes a significant amount of effort, originality, and talent or skill to create." It also tells them it should be clear who is responsible for the website and who created the content, and to research the reputation of both. Those three tests are worth running against your own top ten pages this afternoon.

YMYL and why some pages face a higher bar

Some topics get a stricter standard, and a surprising number of ordinary local businesses touch them.

Google calls these Your Money or Your Life topics, defining them as subjects that "could significantly impact the health, financial stability, or safety of people, or the welfare or well-being of society." Raters apply very high page quality standards to them because a low quality page could do real harm. In a September 2025 revision of the guidelines, Google renamed the societal category YMYL Government, Civics & Society and widened it to cover trust in public institutions and election and voting information.

Businesses that land in YMYL territory without realizing it include anyone writing about financing or payment plans, medical and dental practices, law firms, insurance, home safety, electrical and gas work, and childcare. If that is you, the cost of a thin page is higher than it is for a restaurant menu, and author credentials stop being optional.

The Who, How and Why test

Google offers a self-assessment that is far more useful than any E-E-A-T checklist an agency will sell you, and it is three questions.

• Who. "Is it self-evident to your visitors who authored your content?" A named author with a real bio, not "admin" and not the company name on everything.
• How. Readers benefit from knowing how a piece of content was produced. Say that you tested the product, visited the site, or ran the numbers, and disclose automation where you used it.
• Why. Google calls this "perhaps the most important question": why does this content exist? If the honest answer is "to rank," that shows, and the systems are built to detect it.

The Why question is the one that kills most content programs. A page written because a keyword tool showed volume, on a subject the business has no experience of, will read exactly like what it is.

What a small business should actually build

Here is the version that fits between service calls, ordered by how much it moves relative to the effort.

1. Fix trust first. HTTPS, a real address and phone that match your Business Profile, an about page with photographs of actual people, and policy pages that say what happens if something goes wrong.
2. Put a name on the content. Author bio with license numbers and years in the trade, linked from every article. This is the cheapest expertise signal available and most sites skip it.
3. Publish first-hand work. Job write-ups with your own photographs, before and after, and the part that went wrong. This is the Experience signal and nobody can copy it.
4. Collect and answer reviews. Reputation research is explicitly part of the rater process. Our reputation management work and our guide to Google Business Profile optimization both feed this.
5. Earn citations rather than links. A mention in a local paper, a supplier's case study, a trade association listing. Our notes on earning high-quality backlinks cover the honest routes.
6. Prune what you cannot stand behind. Thin pages written for keywords drag the site's overall assessment. Deleting them is often the fastest quality gain available.

E-E-A-T and AI-written content

The question every business owner asks now, and Google's framework answers it without needing a separate rule.

Nothing in E-E-A-T is about who typed the words. It is about experience, verifiable expertise, reputation and accuracy. Content assembled from other people's articles fails on Experience regardless of the tool used, and content written by a person who has actually done the work passes regardless of the tool used to draft it. Google's How question is the relevant one: be able to say how the content was produced, and be comfortable saying it in public.

The practical risk is volume without substance. Publishing forty generic pages a month gives raters and ranking systems more evidence of low effort, not less.

If you want to know which of your pages would survive a rater's page quality assessment, that is a concrete audit rather than a philosophy. It is where our search work and our content marketing engagements normally start, and the answer is usually that a handful of pages need author bios and a larger handful need deleting.
