What is E-E-A-T?
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness. It is the set of qualities Google asks its human search quality raters to look for when they judge whether a page is helpful and reliable, as described in its Search Quality Rater Guidelines.
Each letter answers a different question. Experience: has the author actually used the product or lived through the situation? Expertise: do they have the knowledge or skills the topic requires? Authoritativeness: is the site or author a recognized go-to source on the subject? Trustworthiness: is the page accurate, honest and safe? Google calls trust the most important member of the family. The first E, for Experience, was added to the older E-A-T in December 2022.
E-E-A-T is a framework, not a single ranking factor. Rater scores do not change the ranking of individual pages; Google uses them to evaluate its ranking systems, which rely on a mix of signals that line up with these qualities. The bar is highest for “Your Money or Your Life” topics such as health, finance and safety.
Why E-E-A-T matters for AI visibility
Google says its SEO best practices remain relevant for AI features in Search, such as AI Overviews and AI Mode, so the same quality signals help decide which pages those answers draw on. Other AI assistants use their own systems to choose sources, but they face the same question Google's raters do: which page can be trusted?
That is where E-E-A-T and AI visibility meet. A page with a named author, first-hand evidence, clear sources and a good reputation on other websites is a safer choice to quote. It gives an assistant a credible source to attribute a claim to, which makes your content a stronger candidate for an AI citation than an anonymous page with the same information.
How to strengthen E-E-A-T
Show experience: add original photos, test results, customer cases and details only someone who did the work would know.
Name your experts: give every article an author with a short bio, relevant credentials and links to their other work.
Build authority off-site: earn mentions and links from respected publications through digital PR, reviews and expert commentary.
Prove trust: cite your sources and keep content dated and current. Make contact details, policies and pricing easy to find.
Go deep on your subject: cover your field thoroughly to build topical authority instead of publishing thin pages on everything.
To see whether this work pays off in AI answers, check whether assistants cite your pages and describe your brand accurately. Trackbase tracks mentions and citations separately across 11 AI models, so you can see where you are named and where you are trusted as a source.
Examples of E-E-A-T
A Dutch bicycle webshop publishes e-bike reviews written by its own mechanics, with photos from real test rides and the battery range they measured themselves.
A B2B payroll software vendor has its tax articles checked by a certified payroll specialist and shows the reviewer's name and review date on every page.
A skincare brand links each health claim to published research and explains in an editorial policy how its products are tested.
A cybersecurity consultancy's founder is regularly quoted in trade media, and those articles later show up among the sources AI assistants cite for security questions.
Frequently asked questions
Is E-E-A-T a Google ranking factor?
Not directly. E-E-A-T comes from Google's Search Quality Rater Guidelines, and rater scores are used to evaluate Google's ranking systems rather than to rank individual pages. Google's systems do use a mix of signals that reflect experience, expertise, authority and trust, so improving those qualities tends to help. Think of E-E-A-T as a description of what Google wants to reward, not a score you can check.
Does E-E-A-T affect AI Overviews and ChatGPT answers?
For Google, yes: Google says its SEO best practices remain relevant for AI Overviews and AI Mode, so the same quality signals apply. ChatGPT, Perplexity and other assistants use their own systems, but they also need to pick sources they can trust. Clear authorship, accurate facts and a strong reputation on other sites make your pages more likely to be used and cited.
How can a small company show E-E-A-T without famous experts?
Start with experience, which is the easiest quality to prove. Show real work: project photos, customer results, test data and the names of the people who did it. Add author bios with relevant qualifications, keep content accurate and dated and collect reviews on independent platforms. Authority follows over time, as other sites and publications start mentioning you.
