If you have read anything about SEO in the last few years, you have probably seen the letters E-E-A-T. Some articles call it the most important ranking factor. Others call it a myth. So beginners ask me, quite reasonably: "What is E-E-A-T, and do I actually need to do anything about it?"
Let me explain it plainly. In this lesson, you will learn what the four letters mean, what E-E-A-T is and what it isn't, why trust sits at the center, and practical ways to show it on your site through authors, sources, about pages and reviews. By the end, you will have a short list of changes you can make this week.
This lesson follows on from helpful, people-first content, so if you haven't read that one yet, I suggest starting there.
What do the letters in E-E-A-T stand for?
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trust (Google uses "trustworthiness" and "trust" for the same idea). It comes from the guidelines Google gives to its search quality raters, which I explain in a moment. Google's overview of the rater guidelines describes each part. In my own words:
| Letter | What it means | Everyday example |
|---|---|---|
| Experience | The creator has first-hand experience of the topic | A review written by someone who actually used the product |
| Expertise | The creator has the knowledge or skill the topic needs | A tax guide written by a qualified accountant |
| Authoritativeness | The creator, the content and the website are known as a go-to source | A trade body's official guidance on its own industry rules |
| Trust | The page is accurate, honest, safe and reliable | Clear prices, real contact details, correct facts |
The first "E," for Experience, was added in December 2022. Google announced it on its Search Central blog in a post titled "E-A-T gets an extra E for Experience." Before that, you will see the older term E-A-T in many articles.
Why add experience? Because sometimes the most useful person to hear from is someone who has done the thing, not someone with a degree in it. If you want to know what it is really like to hike a certain trail, a hiker who walked it last month may help you more than a geography professor.
Is E-E-A-T a ranking factor?
This is where a lot of confusion lives, so let me be precise. Google's guide on creating helpful, reliable, people-first content says that E-E-A-T itself isn't a specific ranking factor. Instead, Google's systems use a mix of many factors that can help identify content with good E-E-A-T.
Think of it like a restaurant inspection. There is no single "cleanliness score" stuck on the kitchen wall. The inspector looks at many separate things (fridge temperatures, surfaces, staff habits) that together show whether the kitchen is clean. E-E-A-T works in a similar way. It is a quality idea that many signals point toward, not a switch you can turn on.
That means a few popular claims are wrong:
- There is no "E-E-A-T score" that Google gives your site.
- Adding an author box or schema markup does not, by itself, create E-E-A-T.
- Search quality raters do not change your rankings.
What do search quality raters do?
Google works with external people called search quality raters. They follow published guidelines to judge how well search results meet people's needs, including whether content shows strong E-E-A-T. Google's page on how it tests changes to Search says these ratings do not directly impact ranking. They help Google check whether its systems are working well. So the raters are like taste testers for a recipe: they don't cook your meal, but their feedback shapes how the recipe is improved.
Why is trust the most important part?
Google's helpful content guide is clear on this: of the four aspects, trust is the most important. The other three support it. Experience, expertise and authority are all reasons to trust a page, but trust is the goal. A page from a well-known expert can still be untrustworthy if it is misleading, and a plain page from a small business can be very trustworthy if it is honest and accurate.
Google also says content doesn't need to show all four. A heartfelt forum post about recovering from a knee injury shows experience without formal expertise, and that can be exactly what a reader wants.
What are YMYL topics?
Some topics need more care than others. Google calls them "Your Money or Your Life" topics, or YMYL. These are subjects that could significantly affect people's health, financial stability, safety or the welfare of society. Think medical advice, investing, legal questions or safety instructions.
For these topics, Google says its systems give more weight to content that shows strong E-E-A-T. In plain words: if your page could hurt someone when it is wrong, the bar is higher. A recipe blog and a page about medication doses are not judged the same way.
How can I show E-E-A-T on my website?
You can't fake E-E-A-T, but you can make the real thing visible. Here are the areas I look at first on any site, in order.
- Clear authors. Add a byline to articles where readers would expect one, linked to an author page with a real bio: the person's role, experience and relevant qualifications. Google warns that made-up authors, AI-generated headshots or false credentials are deceptive. My guide to author pages and bylines shows how to set these up.
- A real About page. Explain who runs the business, how long you have done it, where you are based and why you are qualified. The rater guidelines overview says it should be clear who is responsible for a website. See my guide on writing an About page that builds trust.
- Easy-to-find contact details. A phone number, email, physical address where it applies, and clear customer service information. Hiding how to reach you is a trust problem.
- Cited sources. When you state a fact or number, link to where it came from, ideally a primary source such as an official body or original study. Readers can then check your claims.
- Evidence of experience. Use your own photos, examples, results, measurements and process. Google's guidance on writing high-quality reviews recommends sharing evidence of your own experience, such as visuals or measurements.
- Expert review for YMYL pages. If you publish health, money or legal content, have a qualified person write or review it, and say so on the page. My guide on getting content from subject matter experts explains how to work with busy experts.
- Accuracy and upkeep. Fix errors quickly, update outdated pages, and remove advice that is no longer true. The lesson on content freshness covers how to keep pages current.
- Reviews and reputation. Real customer reviews on your site and on trusted platforms show what others think of you. The lesson on reviews and citations goes into this, and my article on getting more Google reviews gives practical steps. Never buy or fake reviews.
Reputation also comes from outside your site. The rater guidelines overview says raters look at what real users and experts in the field say about a website. Mentions and links from respected sites in your industry help build that picture, which we cover in the lesson on link quality.
What does weak vs strong E-E-A-T look like?
Here are some invented examples to make the difference concrete.
| Element | Weak | Stronger |
|---|---|---|
| Author | "By Admin" | "By Priya Shah, licensed electrician for 12 years" with a linked bio |
| Product review | Specs copied from the maker's website | Own photos, test results and honest pros and cons after real use |
| Health article | No author, no sources | Written or reviewed by a qualified clinician, with sources linked |
| About page | "We are passionate about quality" | Founders' names, history, location, team and credentials |
| Contact | Only a contact form | Phone, email, address and clear returns or service policy |
| Facts | "Studies show..." with no link | The exact study named and linked |
Try it: run a 30-minute E-E-A-T check on your site
Open your website on your phone and pretend you are a cautious first-time customer. Then check:
- Can you tell within ten seconds who runs this business?
- Can you find a phone number or email in two taps or fewer?
- Do your three most important articles show a real author with a real bio?
- Does each factual claim or number on those pages link to a source?
- Are there original photos or examples of your actual work?
- Are customer reviews visible and easy to verify?
- Is anything outdated, such as old prices, old staff or old advice?
Write down every "no." Fix the trust items first (contact details, accuracy, outdated information), then authors and sources, then evidence of experience. Small fixes here help readers immediately, whatever they do for rankings.
Questions beginners ask about E-E-A-T
Is E-E-A-T a ranking factor?
Not directly. Google says E-E-A-T itself isn't a specific ranking factor. Its systems use a mix of other signals that help identify content with good experience, expertise, authoritativeness and trust. So you can't "add E-E-A-T" with one tag or plugin.
Do I need all four parts of E-E-A-T on every page?
No. Google says content doesn't need to show all of them. A personal story about living with a condition shows experience, while a tax guide needs expertise. Trust matters for every page.
Does author schema or a byline improve rankings?
A byline helps readers see who wrote the page, which Google encourages where readers expect it. But a name alone does not create trust. The person needs real knowledge, and the content needs to show it.
Does E-E-A-T matter for small local businesses?
Yes, in a practical way. Clear contact details, real reviews, genuine photos of your work and named staff help customers trust you, and they line up with what Google describes as trustworthy.
Putting E-E-A-T into practice
In brief: E-E-A-T is Google's way of describing content that people can trust, built on real experience, real expertise and a good reputation. It is not a single ranking factor or a score, and raters don't set your rankings. Trust is the heart of it, and it matters most on YMYL topics. Show it with real authors, a clear About page, easy contact details, cited sources, first-hand evidence and honest reviews.
