E-E-A-T (EEAT): what it means for your pages.
What Google means by experience, expertise, authoritativeness and trust, what it does not mean, and why trust signals still matter when AI answers pick their sources.
Short answer
What does this quality framework mean?
E-E-A-T (also written EEAT) stands for experience, expertise, authoritativeness and trust. Google's systems prioritize content that shows expertise, authoritativeness and trustworthiness. One quality signal is whether other prominent websites link or refer to the content.
In brief
Four things to know first.
Four qualities, one center
Google says trust is the most important aspect. The other three contribute to trust.
Not a ranking factor
Google says it is not itself a specific ranking factor. It describes what its systems aim to reward.
Stakes raise the bar
For topics that affect health, money or safety, Google's systems give even more weight to strong trust and expertise.
Trust carries into AI answers
Google says its AI features rest on its core ranking and quality systems.
The four letters
What each E-E-A-T letter stands for.
Google's ranking systems prioritize content that shows expertise, authoritativeness and trustworthiness. The extra E, for experience, covers first-hand knowledge of a topic.
Google says trust matters most. The other aspects contribute to trust, and a page does not have to show all four.
| Quality | In plain words | |
|---|---|---|
| Experience | Experience | First-hand use or knowledge of the topic |
| Expertise | Expertise | Real skill or knowledge in the subject |
| Authoritativeness | Authoritativeness | Other sources look to you as a reference |
| Trust | Trust | Accurate, honest, safe and reliable |
What it is not
E-E-A-T is a standard, not a score
Google says this is not a specific ranking factor. No number on your page carries this name. It describes the quality its ranking systems are designed to reward.
One signal Google names for quality: whether other prominent websites link or refer to the content. Google calls this generally a good sign that the information is trustworthy.
Not a plugin or tag
No markup, file or setting switches it on.
Not only for health sites
Google applies the idea to all content, with extra weight on higher-stakes topics.
Not faked with bylines
Google calls made-up names or false credentials a form of deception.

AI answers
Why trust matters for AI answers.
Google says its generative AI features are rooted in its core Search ranking and quality systems. The same standard that shapes search results shapes which pages feed those answers.
Google also says unique, compelling, useful content will likely matter most for AI search over the long run.
Original over commodity
Google contrasts common-knowledge content with unique expert takes, and advises writing the latter.
Real mentions, not bought ones
Google says seeking inauthentic mentions across the web is not as helpful as it might seem.
Facts that match everywhere
Assistants cross-check sources, so conflicting facts about you weaken trust.
What to do
Show expertise and trust on your pages.
Show trust on the pages buyers and assistants actually read. Start with the ones that answer your most important questions.

FAQ
Expertise and trust: common questions.
Is this a Google ranking factor?
According to Google, it is not a specific ranking factor. It is a way to describe the quality that Google's automated ranking systems are designed to reward: helpful, reliable content created to benefit people rather than to manipulate rankings.
What does the extra E in this acronym stand for?
The extra E stands for experience. It covers first-hand knowledge of a topic, such as having used a product or lived a situation. It sits alongside expertise, authoritativeness and trust, with trust the most important.
Is EEAT the same as the hyphenated spelling?
EEAT is the hyphen-free spelling of the same quality idea. Google says its systems prioritize content that shows expertise, authoritativeness and trustworthiness. One quality factor is whether other prominent websites link to or refer to the content.
Which topics need the strongest trust signals?
Topics that could significantly affect health, financial stability, safety or the well-being of society need the strongest trust signals. Google calls these Your Money or Your Life topics, and says its systems give even more weight to content that shows strong trust and expertise there.
Can you fake these quality signals with author bios?
You cannot fake it with author bios. Google says made-up names, AI-generated headshots or false credentials are a form of deception. Accurate bylines and real author information are strongly encouraged, and false ones signal a low-quality page.
Does this quality standard affect AI answers?
Quality standards like this shape AI answers indirectly. Google says its generative AI features are rooted in its core Search ranking and quality systems, and they retrieve relevant, up-to-date pages from the Search index. Trustworthy pages are what those systems aim to surface.
