E-E-A-T: What It Is and How to Build It on Your Company's Website So That Search Engines and AI Models Trust You

The owner of an accounting firm has been publishing professional articles on taxes for years and clearly explains changes in the law. One day, she asks ChatGPT which accounting firm it would recommend to a client in her region. She doesn’t find her own firm in the response. Instead, a smaller competitor with much more superficial content appears.

The reason isn't the quality of the text. It's a lack of credibility—something that both Google and AI models can detect, even if the reader doesn't mention it at first glance.

This evaluation is called E-E-A-T, and the more search results shift toward AI-generated answers, the more important it becomes. The good news is that you can address most of these signals on your own, without having to rewrite the content you already have.

What Does E-E-A-T Mean, and Why Is It Important to Google and AI Models?

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. Google introduced it as part of the Search Quality Rater Guidelines, a manual for human raters who manually test whether search results actually meet people’s needs. E-E-A-T is not a standalone ranking factor that can be enabled with a single checkbox. It is a set of signals that the algorithm uses to assess whether the content and the website behind it are trustworthy.

Of the four pillars, the last one is the most important: Trustworthiness. Google states this directly—without trustworthiness, even the experience and expertise that a website otherwise demonstrates lose their value. A company may have excellent, expert content on its website, but if it lacks clear contact information, effective security measures, and transparent information about who is behind it, neither Google nor its AI model will trust it enough to recommend it.

In practice, this means the same thing for both a company website and an online store: the more clearly you show who created the content, where it comes from, and how you can be contacted, the easier it is for both Google and your customers to make a decision.

The most common myth: All you have to do is add the author's name below the article

The most common advice regarding E-E-A-T goes something like this: just add the author’s name and photo to the bottom of every article, and you’ve got E-E-A-T covered. This idea used to hold true because the main problem was anonymous content published without any accountability. Today, however, it’s no longer enough—for two reasons.

The first reason is technical: a name below the text doesn’t prove anything on its own. Today, AI tools can generate a fictional expert and even a photo of that person in a matter of seconds, so the mere presence of a name has lost the weight it once had, back when it was a rare and labor-intensive step.

The second reason is related to content: if the text itself is anonymous, inaccurate, or simply a rehash of what’s already been written elsewhere, a name in the header won’t save it. Both Google and AI models look at the big picture: who runs the website can be verified, and the information is consistent across the website, Google, and social media. An author page is a strong signal, but it’s just one piece of the puzzle—not the whole solution.

YMYL: When Both Google and AI Models Are Particularly Strict

The acronym YMYL stands for “Your Money or Your Life,” referring to content that can affect a reader’s health, financial situation, or safety. Google sets significantly higher E-E-A-T standards for such topics, because inaccurate information can have real-world consequences.

The YMYL category clearly includes health, finance, and law, but it also applies to ordinary e-commerce sites. As soon as a website processes payments, enters into contracts, or sells anything related to safety, it falls into this same stricter category. For an e-shop selling children’s clothing, dietary supplements, or financial products, E-E-A-T is therefore not just a theoretical exercise for SEO specialists—it directly influences whether the site even appears in search results where customers can find it.

Even outside of YMYL topics, readers still make decisions based on what they read online. The difference lies only in the degree of risk, not in whether trustworthiness matters.

Specific Signs of Trustworthiness You Can Master This Week

E-E-A-T doesn't require you to rewrite your entire website all at once. Most of the signals are simple, verifiable elements that can be added gradually. We've categorized them based on how quickly you can implement them.

Technical Signals – You Can Set Them Up in a Single Afternoon

• A valid HTTPS certificate throughout the entire website, not just on the home page.
• Contact page with address, phone number, and business ID number, not just a contact form without any additional information.
• Matching Company Information On the web, in your Google Business Profile, and on Firmy.cz—a different name or address reduces trust and local visibility.
• Current Privacy Policy and Terms and Conditions, not a copy from a template from five years ago.

Content Signals – Over the Course of a Month

• The author of each academic text, linked to a page with his professional biography and a link to his LinkedIn profile or another verifiable profile.
• Publication date and date of last update – and make sure the update is genuine, not just a date change with the text left unchanged.
• Citations from Primary Sources where it makes sense: laws, official documentation, public price lists—not just a link to another blog that merely paraphrased the same information.

Social cues – long-term employment

• Real-life references with names and company names, ideally with a link where the customer can verify them, not anonymous quotes like „great company.“.
• Case Studies with Specific Figures instead of a general description of the collaboration.
• Backlinks and mentions from industry websites, which arise naturally when a website consistently publishes content on a single topic over the long term, rather than in a fragmented manner based on which keywords are currently trending.

What's more, the team behind the website doesn't have to be just a name in the footer. It also helps to visually show who is behind the company—how Team photos boost client trust, we addressed that separately.

Our Practice: How to Demonstrate Experience, Not Just Talk About It

The most common mistake isn't a lack of effort, but vagueness. The statement „we have extensive experience with this“ proves absolutely nothing, because anyone can write it. What makes the difference is a specific example—one that no one else can provide.

Instead of the general advice to „publish high-quality content,“ we recommend a specific step: for each key topic on your website, include one real-life case study from your own experience—not a generic guide. For a custom carpentry business, this could be a description of a specific project, including what went wrong during production and how you resolved it. For an accounting firm, it could be a specific situation involving a client where you discovered an error in their tax return and how much it saved them. Numbers, photos, and names (with the client’s consent) turn your text into something that a generic copy-paste job from ten other websites will never offer. This is exactly the principle on which we base the recommendations in the guide, How to Write Case Studies That Are Engaging.

The same logic applies to expertise. A superficial text might say, „Check the contract before signing.“ An expert text explains which specific clause to focus on, why it’s often problematic, and what happens if a company overlooks it. The difference isn’t in the length of the text, but in whether it provides readers with information they wouldn’t find elsewhere.

E-E-A-T and AI Models: Why ChatGPT and Perplexity Only Cite You When They Trust You

E-E-A-T originated as a concept for evaluating search quality, but AI models today operate using the same logic. When ChatGPT, Perplexity, or Gemini decide which source to cite in a response, they look for the same things as Google: it’s clear who wrote the content, it can be verified, and it aligns with what other sources say about the company. This discipline is known as GEO, or Generative Engine Optimization, and we’ve broken it down in detail in an article about it, How to Adapt Your SEO Strategy So You're Visible in AI Models, Too.

In practice, this means that a website with anonymous content doesn’t stand a chance in AI responses, even if it’s technically optimized to perfection. This is also confirmed by our own search volume research on this topic: nearly a third of the questions people ask ChatGPT and Gemini about E-E-A-T are directed specifically at service providers— „where can I find consultants for E-E-A-T optimization,“ „how do I choose an agency that will help me with my website’s credibility.“ People are therefore using AI models as a way to find service providers, and this role will only grow as more people start their searches directly in chat rather than in a traditional search engine.

Whether or not AI models cite you can now be measured to some extent. Google Search Console now shows reach beyond traditional search, similar to what we wrote in the article about how Search Console Now Measures Reach on Social Media as Well, and Bing, on the other hand, directly displays, which pages it cites in its AI responses. For the first time, both tools provide specific feedback on whether the E-E-A-T signals you're building on your website are actually working.

Corporate Website or Online Store? Where E-E-A-T Is Handled Differently

The principles are the same, but the emphasis differs depending on whether you're selling a product or a service.

U online store E-E-A-T isn't just evident on the blog, but mainly in the shopping section. A product page with a catalog description from the manufacturer doesn’t add credibility—your own photos, actual dimensions, personal experience using the product, or honestly stated drawbacks work much better. Equally important are the terms and conditions, actual availability, and a transparent returns process, because this is where the customer decides whether to entrust you with their payment information.

U company website featuring services Essentially, the customer is buying specific people who will do the work. It therefore helps to show who will actually be working on the project, how long they’ve been in the field, and what specific projects they’ve already handled. The phrase „We’ve been building websites for 15 years“ is more specific and credible than „We’re top professionals“—and it works even better when you add what exactly those 15 years entailed.

Both types of websites also benefit from the fact that they aren’t ashamed of their work and showcase it publicly—we addressed a similar topic—why companies are afraid to share a link to their own website—in an article „We do not send a link to the website“.
