E-E-A-T explained: how experience, expertise and authorship help your website

E-E-A-T stands for Experience, Expertise, Authoritativeness and Trust. It comes from Google's Search Quality Rater Guidelines, the handbook Google gives to the people who test its search results. Google says E-E-A-T is not a specific ranking factor on its own, but its systems use signals that line up with it, and trust matters most. For a business website, that means showing who wrote your content, why they know the subject, how the content was made, and that your business is real. Bylines, author pages, structured data, original photos and honest reviews are how you show it.

Below is what Google actually says, and the practical steps we use when we build sites.

What E-E-A-T means

Each letter is a question a reader (or a Google rater) might ask about your page.

The original framework was E-A-T. In December 2022, Google published a Search Central post titled Our latest update to the quality rater guidelines: E-A-T gets an extra E for Experience. The new E recognizes that first-hand experience can make content useful even when the writer is not a formal expert. A product review from someone who used the product for a month is a good example.

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

Not directly. Google's page on creating helpful, reliable, people-first content says "E-E-A-T itself isn't a specific ranking factor." It then explains that Google's systems use a mix of signals to find content that shows good E-E-A-T.

The rater guidelines work the same way. Raters score sample results, and Google uses those scores to check whether its systems are working. A rater's score does not move your page up or down. So there is no E-E-A-T number to chase. The goal is to make your pages the kind of content those signals are built to find. You can read more about that context in our post on what Google thinks about AI writing.

Trust is the most important part

Google is clear about which letter matters most. The helpful content page says: "Of these aspects, trust is most important." The current Search Quality Rater Guidelines (dated September 11, 2025) put it this way: "Trust is the most important member of the E-E-A-T family."

Experience, expertise and authority all support trust. A page does not need to show all of them. A local plumber's blog post does not need a PhD behind it. It does need to be accurate, honest and clearly from a real business.

Why YMYL topics raise the bar

Some topics carry more risk if the content is wrong. Google calls them Your Money or Your Life topics, or YMYL. The rater guidelines describe them as topics that "could significantly impact the health, financial stability, or safety of people." Google's helpful content page says its systems give even more weight to strong E-E-A-T on these topics.

If your business is in law, tax, finance, insurance, healthcare, real estate or anything safety-related, E-E-A-T is not optional. Your content needs named experts, clear credentials and a review process you can point to.

Authorship: Google's Who, How and Why

Google's helpful content page asks site owners to think about three questions.

Who created the content? Google says readers should be able to easily tell who wrote it. It writes: "We strongly encourage adding accurate authorship information, such as bylines." It also says bylines should lead to more information about the author.

How was it created? Explain your process where readers would care. For reviews, that means saying how many products you tested and showing photos or results. If you used AI or automation, Google suggests disclosing it where readers would reasonably wonder.

Why was it created? Google calls this the most important question. The answer should be to help people, not just to attract search traffic.

What good authorship looks like

• A byline on every article with a real person's name, linked to their author page.
• An author page or bio with a photo, role, years of experience, credentials and the topics they cover.
• Links to other profiles such as LinkedIn, a professional license lookup or a personal site. In schema, these go in the sameAs property.
• Dates. Show when the article was published and when it was last updated.
• An editorial process. A short page explaining how you research, write, fact-check and update content.
• "Reviewed by" for YMYL content. If a tax article is written by a marketer, have a licensed professional review it and name them on the page with their credentials.

Do not fake it

Google's current helpful content page (last updated October 5, 2026) is direct about fake authors. It warns against "Fabricating creator profiles (such as by using AI-generated headshots, made-up names, or false credentials" and calls this "a form of deception." That rules out stock photo "experts," invented staff writers and AI-generated faces. If one person writes everything, that is fine. Just make it the real person.

Structured data for authors

Structured data, also called schema markup, is code that tells search engines what a page is about in a format machines can read. For authorship, three types matter most.

Article or BlogPosting. Google's Article structured data docs list author, author.name, author.url, datePublished, dateModified, headline and image as recommended properties. Google's author best practices say to put only the person's name in author.name, to use the Person type for people, and to point author.url at a page that uniquely identifies the author. Google says sameAs can be used as an alternative for that link.

ProfilePage. Google's ProfilePage docs say this markup is meant for sites where creators "share first-hand perspectives," and they list blog "About Me" pages and author pages as valid uses. The required property is mainEntity, the person the page is about. Recommended properties include image, sameAs and description.

Organization. This describes your business: name, logo, URL, contact details and social profiles. It connects your authors to a real company.

Here is a simple example for a blog post, using placeholder values:

{
  "@context": "https://schema.org",
  "@type": "BlogPosting",
  "headline": "How to Choose a Water Heater",
  "datePublished": "2026-10-01",
  "dateModified": "2026-10-15",
  "image": "https://www.example.com/images/water-heater.jpg",
  "author": {
    "@type": "Person",
    "name": "Jane Smith",
    "url": "https://www.example.com/author/jane-smith",
    "jobTitle": "Licensed Master Plumber",
    "sameAs": [
      "https://www.linkedin.com/in/janesmith-example"
    ]
  },
  "publisher": {
    "@type": "Organization",
    "name": "Example Plumbing Co.",
    "url": "https://www.example.com",
    "logo": "https://www.example.com/logo.png"
  }
}

The author page at /author/jane-smith would then carry its own ProfilePage markup with Jane as the mainEntity. Always make sure your schema matches what is visible on the page. Google's AI features guidance lists that as a good practice. For more on schema formats, see our guide to llms.txt, schema and Open Graph.

How to show experience on a business site

Experience is the easiest letter for a small business to prove, because you already have it. You just need to put it on the page.

• Original photos. Real jobs, real staff, real products. Stock photos say nothing about you.
• Case studies. The problem, what you did and the result, with numbers where you can share them.
• Process explanations. Walk readers through how you actually do the work.
• First-hand testing. If you recommend tools or products, say you used them and show what happened.
• Real reviews. Show genuine customer reviews. The FTC finalized a rule banning fake reviews on August 14, 2024. It covers reviews from people who do not exist (including AI-generated ones), buying positive reviews and undisclosed insider reviews, and it lets the FTC seek civil penalties.
• Clear About and Contact pages. The rater guidelines tell raters to check who is responsible for a site, often through "about us" and "contact us" pages.
• Policies. Privacy policy, refund or service terms and an editorial policy all signal a real, accountable business.
• Business details. Keep your name, address and phone number consistent everywhere. Our guide to NAP+W consistency explains why.
• Cited sources. Link to original sources for facts, laws and statistics.

Good writing ties it all together. Our post on why website copywriting matters covers how to sound like a real expert and not a template.

E-E-A-T and AI search

Google says there are "no additional requirements to appear in AI Overviews or AI Mode," and that normal SEO basics still apply. Its AI features page points to its helpful content guidance as a key practice. That same guidance is where E-E-A-T and the Who, How and Why questions live.

Beyond that, we are reasoning, not quoting. AI tools that answer questions have to choose which sources to trust and cite. It makes sense that pages with a named expert, clear dates, cited sources and consistent business details are easier to trust and easier to describe correctly. Clear author schema also helps machines connect a page to a real person and company. None of this guarantees a citation, but it removes doubt. Our post on answer engine optimization goes deeper.

E-E-A-T checklist

We do this on our own site

This site follows the same rules. Every post carries a byline that links to our author page, which lists real experience and links to outside profiles. Behind the scenes, posts use BlogPosting markup with a Person author, and the author page uses ProfilePage markup with Person as the main entity. If you want to see how a careful AI-assisted workflow fits with real authorship, read our guide to using Claude for SEO.

The short version

E-E-A-T is not a switch you flip. It is proof that real, qualified people stand behind your content and your business. Put real names on your articles, build honest author pages, add matching schema, show your actual work and never fake reviews or authors. Trust comes first, and on money, health and legal topics it counts even more.
