What Is E-E-A-T?

E-E-A-T is Google's framework of four qualities, experience, expertise, authoritativeness and trust, used to describe a high-quality source of information. For a health practice, it asks one question about every page you publish, which is whether a reader should believe the person behind it. It appears in Google's Search Quality Rater Guidelines, the document Google gives its human reviewers, and those guidelines call trust the most important of the four.

How E-E-A-T works

The guidelines are written for Google's human reviewers, who use them to judge page quality. They show what Google considers important. They do not publish how the ranking systems work, so read them as a picture of the goal.

Here is how the guidelines define each part.

• Experience. Whether the creator has the necessary first-hand or life experience for the topic.
• Expertise. Whether the creator has the necessary knowledge or skill for the topic.
• Authoritativeness. Whether the creator or the website is known as a go-to source for the topic.
• Trust. The center of the family. The guidelines say untrustworthy pages have low E-E-A-T no matter how experienced, expert or authoritative they seem.

Google adds two clarifications in its helpful content guidance. First, E-E-A-T itself is not a specific ranking factor. Second, Google's systems use a mix of signals that can identify content with strong E-E-A-T. The same page says Google's systems give even more weight to content that aligns with strong E-E-A-T for topics that could significantly affect health, financial stability or safety. Health care is one of those topics, and the label for them is YMYL.

Raters look for evidence in specific places. The guidelines tell raters to start with the website's About page or the creator's profile, and to find out who is responsible for the site and who created the content on the page. Google's guidance says to add accurate authorship information, such as bylines, where readers would expect it, and it warns against deceptive authorship such as fabricated creator profiles.

One section of the guidelines is directly useful for clinics. It separates experience from expertise on health topics. A patient sharing what treatment felt like can show valuable first-hand experience. Information such as the different treatment options for liver cancer and life expectancy under each is listed as best left to experts. The takeaway is that a clinical explanation should come from a clinician, and a patient story can sit next to it as support.

Trust has a practical meaning for a clinic. It is the page being accurate, honest and clear about who stands behind it. A beautifully designed page full of unsupported claims scores low on trust, and the other three qualities cannot rescue it. A plainer page with a named clinician and sources can score higher.

Google also offers a self-check called Who, How and Why. Who created the content, how it was created, and why it exists. Google says the why is perhaps the most important question, and that people-first content is created primarily for people and not to manipulate rankings.

Example: E-E-A-T at a health practice

This example is illustrative, not a transcript. Two functional medicine clinics in the same metro area each publish a page on thyroid testing.

The first page has no author. The text is generic, the About page lists no providers, and a stock photo of a doctor sits at the top. A reader cannot tell who is responsible for what the page says.

The second page names the physician, shows her credentials and state license, links to her bio and says how many years she has practiced. It describes what the first visit includes in her own words, cites the guideline behind each test, and ends with the clinic's address and phone. Every claim is something she can stand behind, and a reader can check it.

Both pages may carry similar information. Only the second one gives a rater, or an AI tool deciding whom to quote, something to confirm. The difference costs the clinic an afternoon of writing and a conversation with its physician. You can see the same logic in where AI tools look. In MGMA's June 2026 analysis of 33,340 ChatGPT citation events across 200 practices, specialty association credentialing pages made up 22.1% of citations and state medical board profiles 5.1%. Those are pages outside your site that state who a provider is. Authoritativeness is partly built from what independent sources say about you.

The caution is that the MGMA piece was written by the founder of a commercial AI growth service and covers one platform. It supports the idea that credentials matter. It does not give a formula.

Not every page needs the same scrutiny. In my judgment, any page that gives health advice, mentions a guarantee, compares you to a competitor, describes an identifiable patient or makes a regulated claim deserves an extra review before it goes live. Verify the names, dates and claims, confirm you have permission for anything about a patient, and take out loaded language. Save the sources and approvals, and add a second reader when the stakes are high. Put the reviewer's name and review date in the body of the page, not only in a byline, so the proof travels with the text.

Two editing habits help. Hedge clinical wording where the evidence is mixed, with phrases such as "can help" or "in many cases". If an AI tool drafted the page, edit for judgment as well as grammar, since drafts can sound more certain than the evidence allows. Staff rules for that are covered in AI use policy.

How to check yours in 60 seconds

1. Open one of your condition or treatment pages.
2. Find the author. Is a real, credentialed person named, with a link to a bio?
3. Look for a clear About page, a physical address and contact details.
4. Check whether claims cite sources a reader can open.
5. Ask whether a stranger could tell, from the page alone, who is responsible for it.
6. Search your top provider's name and see whether an independent page, such as a board or association listing, confirms the credentials on your site.

Each missing item is a gap to close.

What to do about it

1. Put a named, credentialed author or medical reviewer on every clinical page.
2. Build a bio page per provider with training, licenses, specialty and the clinic they belong to.
3. Describe real experience in specifics the provider can stand behind, written or reviewed by the provider.
4. Cite primary sources such as studies, guidelines or government health pages for clinical claims.
5. Make your name, address, phone and credentials match across your site, your Google listing and your NPI record.
6. Use a single page that defines your practice, then link your providers and profiles back to it.
7. Add a last reviewed date, and update the page when guidance changes.
8. On comparison pages, label what is fact, what is opinion and what is only a claim you cannot confirm.
9. Ask each provider to read their own pages once a quarter and flag anything that is out of date or overstated.

Start with the pages that drive the most inquiries, since those carry the most weight for your practice.
