E-E-A-T
What is E-E-A-T?
E-E-A-T stands for experience, expertise, authoritativeness and trustworthiness. It is a framework from Google’s Search Quality Rater Guidelines for judging whether content and its creator can be relied on. Google added the first E, experience, in December 2022. Trust is the most important of the four.

Each letter asks a different question. Experience: has the creator actually used the product, visited the place or lived through the situation? Expertise: do they have the knowledge or skill the topic needs? Authoritativeness: is the creator or site a recognised go-to source on the subject? Trustworthiness: is the page accurate, honest, safe and reliable? Google’s guidelines describe trust as the centre of the framework, with the other three supporting it. A page can be untrustworthy even if it looks expert, for example a store with no contact details or a review written by someone paid to praise the product.
E-E-A-T is not a single ranking factor or score. Google has said there is no E-E-A-T score in its systems. Instead, its ranking systems use a mix of signals that Google intends to align with what raters judge as high E-E-A-T, and raters’ assessments help Google check whether its systems are working. Google also says it gives E-E-A-T more weight for topics that could affect people’s health, finances, safety or wellbeing, known as YMYL topics.
What counts depends on the topic. For a medical treatment, formal expertise and accuracy matter most. For a review of hiking boots, first-hand experience of wearing them may matter more than a qualification. For a forum post about living with a condition, lived experience is valuable in itself.
E-E-A-T comes from both on-page and off-page evidence. On-page: who wrote the content, their background, sources cited, original photos and data, clear contact and business information, and accuracy. Off-page: what independent sources say about the site and author, such as reviews, press coverage, awards and mentions. Raters are told to look for reputation information from outside the site rather than only what a site says about itself.
Why E-E-A-T matters for SEO
E-E-A-T describes what Google is trying to reward. When content is similar in relevance, the source that shows real experience and earns trust tends to win, especially after core updates that refine how quality is assessed.
For YMYL topics, weak E-E-A-T can keep a site from ranking at all. Google wants to avoid showing unreliable health or financial advice, so it leans heavily towards trusted sources there.
Building E-E-A-T also helps beyond Google. AI assistants and answer engines favour sources that are widely cited and clearly credible, and readers trust content with a named, qualified author.
How to improve E-E-A-T
- Show who created the content. Add author names, short bios with relevant experience or qualifications, and author pages.
- Show first-hand experience: your own photos, test results, measurements, screenshots, and specific details only someone who did it would know.
- Cite reliable sources for factual claims and keep content accurate and up to date. Fix or remove outdated advice.
- Make the site trustworthy: clear contact details, an about page, editorial and review policies, secure checkout and easy-to-find returns or refund information.
- Have experts write or review YMYL content, and say who reviewed it.
- Build reputation off your site: earn coverage, reviews and links from respected sources in your field, and respond to criticism honestly.
- Avoid things that destroy trust: misleading titles, hidden affiliate relationships, fake reviews and content written to rank rather than to help.
E-E-A-T example
Two pages review the same robot vacuum. Page A rewrites the manufacturer’s specs and links to a shop. Page B is written by a named reviewer who used it for a month in a flat with two dogs, shows her own photos of the dustbin after a week, measures noise levels, explains what it failed to clean and discloses the affiliate link. Page B shows experience, expertise and trust; it is the kind of page Google’s systems aim to rank higher.
E-E-A-T FAQ
Is E-E-A-T a ranking factor?
Not directly. Google says there is no E-E-A-T score. Its ranking systems use many signals intended to reward content that shows E-E-A-T, and quality raters use it to assess search results.
What is the difference between E-A-T and E-E-A-T?
E-A-T was expertise, authoritativeness and trustworthiness. In December 2022 Google added experience to the rater guidelines, making it E-E-A-T, to recognise the value of first-hand experience.
Which part of E-E-A-T matters most?
Trust. Google’s rater guidelines say trust is the most important member of the E-E-A-T family, and that experience, expertise and authoritativeness all feed into it.
Do author bios help SEO?
They help readers and quality raters see who is behind content, which supports trust. A bio alone won’t lift rankings; the expertise must also show in the content and reputation.
