What Is E-E-A-T? Reflecting Trust Signals on Your Site

E-E-A-T is one of the much-discussed but little-understood ideas in SEO. Some think it's a secret Google score; others think it only applies to big media sites. Neither is true.

E-E-A-T is a framework from the guidelines Google writes for the human raters who evaluate the quality of search results. For a small business, its meaning is very concrete: how easily is someone visiting your site convinced that you really know this work and can be trusted?

The four letters of E-E-A-T

Experience. The content creator having lived the topic firsthand: actually using a product, actually delivering a service, solving a problem in the field. This letter was added to Google's guidelines later.

Expertise. Knowledge and skill in the topic. Like a dentist writing about implants or an accountant writing about tax.

Authoritativeness. The person or business being recognized as a source by others in their field. Your name appearing in industry associations, local press or on other sites are signs of it.

Trustworthiness. Google's guidelines define this as the most important of the four; the other three contribute to trust. Accurate information, a real and reachable business, and a secure site all fall under it.

Is it a ranking factor?

Not directly. According to Google's statements, E-E-A-T isn't a single number or score measured in the algorithm. Ratings from quality raters don't directly change individual sites' rankings either; Google uses them to test whether its algorithms work well.

But the algorithms do try to surface the kinds of signals E-E-A-T describes. So E-E-A-T is a direction, not a target. When you strengthen your site along these four ideas, you move closer to the kind of site Google wants to reward.

It carries even more weight in areas that can affect people's health, money or safety. Google calls these “Your Money or Your Life” (YMYL) topics. Dental clinics, law firms, accountants, psychologists and financial advisers fall into this category; missing trust signals are noticed more on these sites.

Showing experience on your site

Experience is something AI can't easily produce, which is why it's becoming more valuable.

The most effective way to show it is real examples from your own work. For a kitchen renovation company: before and after photos shared with the client's permission, how long the job took, an unexpected problem on site and how it was solved.

Professions with advertising and promotion rules are different. For lawyers, doctors, dentists and psychologists, patient or client testimonials, before-and-after images, success rates or phrases like “the best” may conflict with professional rules. In these professions, show experience through informative content that explains processes and common questions in general terms without using anyone for promotion, and check what can be published against the current rules of your bar, chamber or professional association.

In blog posts too, add your own observations instead of repeating general knowledge. Anyone can write “boilers should be serviced once a year.” Only someone doing the job can write a sentence about a problem they genuinely see often in the boilers they service, such as filters that have never been cleaned and how that affects heating.

Real photos are part of experience too. A site full of stock photos doesn't look like it belongs to someone who actually does the work.

Expertise and author information

It should be clear who wrote the content. Especially in health, law and finance, there's a big trust gap between an unsigned article and one carrying the expert's name.

Add a short author box under blog posts: the author's name, title, a brief background and photo. Link from the author box to an About or team page that introduces them in more detail. The team page should include concrete evidence of expertise: education, certificates, professional chamber registration, years in the field.

Even if content is prepared by an agency or copywriter, having it reviewed by the in-house expert, and saying so, helps. A note like “This article was reviewed by Dr. X” reassures readers only if it's true.

Trust signals

Trust is felt across the whole site. Most of the work involved isn't technical or expensive:

• A clear address, a landline or a business mobile number, opening hours and a map
• The business's official name, tax details and any professional chamber registration number
• Real customer reviews, preferably from an independent platform like Google (if your professional rules allow)
• Transparent information about prices, return terms and process
• Content kept up to date: a promotion that ended years ago erodes trust
• HTTPS, a KVKK privacy notice and a cookie policy
• Sourced data; no made-up statistics or unsupported claims

Transparency is decisive here. A site whose contact page has only a form, with no address or phone, struggles to inspire trust however well it's designed. We listed the elements of a trustworthy website in more detail in a separate post.

Trust in how AI picks sources

Tools like ChatGPT, Gemini, Perplexity and Google's AI Overviews decide which sources to use when answering a question. Exactly how that decision is made hasn't been disclosed. But the tendency we've observed overlaps heavily with the signals E-E-A-T describes: pages that answer clearly, have a known author and business, offer information consistent with other sources and are up to date seem to get cited more often.

Having the same business details on your website, Google Business Profile and other platforms matters here too. A business whose details don't match is an unclear source for AI as well. We explained the other steps to visibility in AI search in a separate post.

If you want an E-E-A-T checklist, we suggest the simplest test: open your site through the eyes of someone seeing it for the first time, who has never heard of you. Can you find, within two minutes, who does this work, how long they've done it, where they are and what past customers say? Every piece of information you can't find is a trust signal waiting to be added.
