What Is E-E-A-T? Experience, Expertise, Authority and Trust

E‑E‑A‑T (Experience, Expertise, Authoritativeness, Trust) is the set of four criteria Google uses to describe the quality and credibility of content. Google itself stresses that E‑E‑A‑T isn’t a specific ranking factor, but its systems use many signals that help identify content with good E‑E‑A‑T. The most important element is trust, and it matters most for YMYL topics – health, finance, safety.

E‑E‑A‑T is an acronym borrowed from Google’s Search Quality Rater Guidelines. In practice it affects SEO indirectly – by improving a site’s credibility and value for users. This matters especially for so-called YMYL (‘Your Money or Your Life’) sites, e.g. about health, finance or safety, where low-quality content can genuinely harm the user.

According to the guidelines, the most important pillar of E‑E‑A‑T is trust – the other three support the assessment of how far a page can be trusted. Building E‑E‑A‑T is therefore about delivering high-quality, reliable and original content, created by credible authors with proven knowledge and experience.

Element	The question it answers	Example signals
Experience	Does the author know the topic first-hand?	Your own photos, tests, project write-ups, case studies
Expertise	Does the author have knowledge and skills in this field?	Qualifications, professional practice, reliable sources, depth of detail
Authoritativeness	Is the author or site a recognised source on the topic?	Citations, links and mentions from credible sites, industry publications
Trust	Is the content accurate, honest and safe?	Company details and contact information, clear policies, correct information, site security

How E‑E‑A‑T affects SEO

E‑E‑A‑T isn’t a separate algorithm or a single ranking factor. In its documentation on creating helpful content, Google says plainly that while E‑E‑A‑T itself isn’t a specific ranking factor, it uses a mix of factors that can identify content with good E‑E‑A‑T. It adds that for topics that could significantly impact people’s health, financial stability or safety, its systems give even more weight to content with strong E‑E‑A‑T.

Quality raters (people who evaluate search results) check whether pages meet the E‑E‑A‑T criteria. Their ratings don’t change the rankings of specific pages – Google uses them to check whether changes to its algorithms send users to valuable sources. In practice, this means content created by people with experience and knowledge, published on trustworthy sites and backed by credible sources, is exactly what Google wants to show near the top. I write more about what actually affects rankings in my post on Google ranking factors.

Optimising for E‑E‑A‑T is therefore mainly about working on your site’s credibility and substance – you show genuine experience, specialist knowledge and a good reputation in your content, rather than ‘adding’ one magic ingredient.

Where E‑E‑A‑T came from and what has changed in the guidelines

For years the guidelines used the abbreviation E‑A‑T. In December 2022 Google added a second ‘E’ – Experience, meaning first-hand experience. Since then we’ve been talking about E‑E‑A‑T.

The guidelines are updated regularly. The latest version of the Search Quality Rater Guidelines I’ve checked is dated 11 September 2025. The most important changes in recent years, according to the changelog in the document itself:

• January 2025: the sections on Lowest and Low ratings were aligned with Google’s spam policies and examples were added. The guidelines gained a definition of generative AI and a description of scaled content abuse – e.g. producing many pages with little effort using automated tools, including AI, with no added value for the user.
• September 2025: the YMYL definitions were updated – alongside health, safety and finance, the ‘Government, Civics & Society’ category was named explicitly (including information about elections and public institutions).

Important: the guidelines don’t treat the use of AI as a problem in itself. They state outright that generative AI tools can be used to create both high-quality and lowest-quality content – what counts is effort, originality and added value for visitors.

Experience

Experience means the author of the content knows the topic personally, ‘first-hand’. Google encourages you to consider whether the creator has practical life or professional experience related to the topic. For example, a product review written by someone who has actually tested the product is more credible than one written from the armchair. In reviews and guides especially, it’s worth showing proof of experience (photos of the product in use, test records, video of it in action).

How to strengthen Experience: Try to create content that includes your own experiences or case studies. If you’re writing about building a house, describe the stages of your own project or share a write-up of the build. Add photos, videos or data that prove the work was done. Show the author’s ‘human face’ too – a few words about their background in the topic or a work diary. In industries such as modular home building, an account of building your own house does a great deal to make the content trustworthy. Keep the experience current as well – e.g. if you’re describing a product, say when and in what context you used it.

Expertise

Expertise is the author’s range of knowledge and skills in a given field. The point is whether the content is created by people who specialise in the topic – whether they have the right qualifications, education or practice. The level of expertise required depends on what the page is about. A ski enthusiast is enough for a simple list of ski runs, but an article on freeriding in the Alps (which may affect someone’s safety) should be written by an instructor or a mountain rescuer. From an SEO point of view, check whether the author has proven credentials (a degree, certificates, years of practice, etc.).

How to strengthen Expertise: Work with recognised specialists and professionals. If you run a finance blog, ask a certified financial adviser to review or sign off the content. Mention the author’s qualifications in the text (e.g. ‘10 years’ experience in the industry’, ‘chartered civil engineer’). Bring in reliable data, statistics and sources – e.g. links to studies, reports or official industry websites. Add interviews or expert quotes to show depth of knowledge. In technical or medical guides, avoid generalities – detailed instructions backed by practical knowledge (e.g. a procedure described by a practitioner) clearly raise the perceived expertise. Remember, though, that in YMYL topics formal proof of qualifications is what counts – scientific publications, licences or reviews by other experts. I explain how to turn this into an actual piece of writing in my guide on how to write SEO content.

Authoritativeness

Authoritativeness means the author or site is perceived as a recognised source of knowledge. You get there when other specialists, influential authors or reputable sites cite and recommend your content. For example, if a finance blog is quoted by local media or other economists link to its analyses, it gains authority in the field. Authority is ‘one step further’ than expertise – it’s recognition and respect in the industry. An authoritative site is the one people turn to first when they’re looking for information on a topic.

How to build Authoritativeness: Regularly publish valuable, original content that attracts the attention of other creators. Get involved in industry events (e.g. conferences, webinars) and share your knowledge there; mentions of these activities will help build your image. Write guest articles for recognised portals and earn citations from other sites. Look after a strong brand – consistent branding and a professional website. Authority also grows through recommendations from users and customers – positive reviews or recommendations on independent forums show the brand’s reputation. It’s also important to show the ‘author’s authority’ – put the author’s photo, a short bio and a list of achievements on display (podcast appearances, articles in trade magazines, awards). You don’t have to be an expert in everything – build authority in your niche or invite professionals to contribute as guest authors.

Trust

Trust is the most important element of E‑E‑A‑T – the guidelines say outright that untrustworthy pages have low E‑E‑A‑T no matter how experienced, expert or authoritative they may seem. They even give a vivid example: a financial scam remains untrustworthy even if it’s run by an ‘experienced scam expert’. Trust means the user can use the site’s content and services without worry. This covers both honesty of substance (accurate information, nothing misleading) and technical and reputational aspects. Quality raters give lower ratings to pages that seem suspicious, are misleading or were created mainly to manipulate search results. In practice, you have to show that you care about security and transparency.

How to strengthen Trust: Above all, make your site as reliable as possible. Give real data and reviews – don’t buy fake reviews or hide negative feedback. Look after security – use an SSL certificate (an ‘https’ address), show trusted payment methods (especially in e-commerce) and provide customer support (e.g. chat, a helpline). Put full contact details on the site (address, phone), information on who is responsible for it, a privacy policy and terms and conditions. In finance or medicine, disclose the authors’ qualifications and the sources of information (references, links to studies, government websites). If you run an online shop, display external credentials (e.g. industry certificates, ratings, quality badges). Remember accessibility too – the site should work well on mobile devices and be readable, for example, for people with visual impairments.

Who, How, Why – the questions Google suggests

In its documentation on creating helpful content, Google suggests assessing your own content through three questions. It makes a good, practical E‑E‑A‑T checklist:

• Who (created the content): is it clear to visitors who the author is? Are there author bylines leading to information about them? Google also warns against fabricating creator profiles – e.g. with AI-generated photos, made-up names or fake credentials.
• How (it was created): is it clear how the content was produced – e.g. how many products were tested for a review, and how? If you use automation, including AI, Google suggests considering whether this is obvious to readers, e.g. through a suitable disclosure.
• Why (it was created): is the main purpose to help people or to attract search engine traffic? Using automation, including AI, mainly to manipulate rankings violates Google’s spam policies.

Key factors that build trust

• Structured data (schema.org): Marking up content with schemas (e.g. Article, Product, Review) helps search engines understand who the author is, when the content was published and updated, and – for products – what ratings they have. It can also make you eligible for rich results, although Google doesn’t guarantee them. Structured data alone doesn’t ‘add’ E‑E‑A‑T – it has to describe what’s actually visible on the page.
• Author information: Adding information about the author (photo, short bio, job title) and marking them up in structured data (the Person type) makes it easier to link the content to a specific, real creator. I go into the details below.
• User reviews and ratings: Both product or service reviews on the site and customer reviews on external platforms (Google Maps, Facebook, industry review sites) are a strong credibility signal. The rater guidelines in fact tell raters to check the reputation of the site and its creators in independent sources. Genuine positive reviews build trust among new users and prove the quality of what you offer.
• Social media signals: Although the direct impact on SEO is debatable, strong brand activity and reach on social media (mentions, shares, recommendations) improve recognition and can translate into organic traffic. They show that many people trust your brand.
• Technical security and transparency: Make sure the site runs on HTTPS with a valid SSL certificate, has no technical errors (e.g. broken links and 404 pages), loads quickly and has working forms. Provide clear information about your privacy policy, cookies and purchase/return procedures. Links to credible sources (e.g. government websites, scientific publications) also strengthen the sense of security.

Author structured data – Person and Article

In its documentation on Article structured data, Google notes that no properties are required – you add the ones that fit your content. For the author, though, it gives specific best practices:

• Include all authors shown on the page, and when there are several, list each one as a separate object in the author property.
• Put only the name in author.name (or the organisation’s name) – no titles, job positions, dates or prefixes such as ‘posted by’.
• Use the right type: Person for a person, Organization for a company or editorial team.
• Add supporting fields, e.g. author.url – a link to a page that uniquely identifies the author (e.g. their ‘About me’ page or author profile on the site), and optionally sameAs with their profiles on other sites.

It’s also worth filling in datePublished and dateModified – especially when you update content. You can check the implementation with the Rich Results Test and the Schema Markup Validator. Remember that the markup has to reflect what the user sees on the page – marking up an author in the code who doesn’t appear in the content builds nothing.

Tools for analysing and improving E‑E‑A‑T

When working on E‑E‑A‑T, it’s worth using tools that help diagnose problems and build on your strengths:

• Google Search Console: Provides data on how users find your site (queries, CTR, positions). Shows indexing errors and structured data reports. Lets you monitor Core Web Vitals (aspects of UX) and security issue notifications.
• Google Analytics: Lets you track how users behave on the site – a low engagement rate or short time on page may suggest the content doesn’t meet readers’ needs. Analysing traffic sources reveals which sites visitors come from (which indirectly says something about authority).
• Structured data testing tools: (e.g. Google’s Rich Results Test, the Schema Markup Validator) let you check that the schemas you’ve implemented are correct. They help eliminate errors, so the search engine understands the page content better.
• Review and media monitoring: Google Alerts, Brand24 or other mention-tracking platforms let you collect what people say about your brand online – both positive and critical. They help you react quickly to new reviews or negative comments, which increases customer trust.
• SEO tools for link and competitor analysis: (e.g. Ahrefs, Semrush, Majestic) – show the backlink profile, popular keywords and competitors’ content. Analysing backlinks helps you understand a site’s authority – what counts above all is links and mentions from well-known, credible and topically related sources, not their sheer number.
• Usability and accessibility testing tools: (e.g. Lighthouse, PageSpeed Insights, WCAG accessibility checkers) – although they’re mainly about UX, they indirectly support trust: a fast, functional site that’s accessible to all users meets visitors’ expectations better.

Examples of E‑E‑A‑T in different industries

E-commerce: For online shops credibility is key. Trust is built here by things like an SSL certificate, secure payment methods, full contact details and a returns policy visible on the site. Customer reviews matter too – if products have plenty of positive reviews, new customers are more willing to buy. An FAQ section and live chat are also good examples, showing that the company cares about customer service. From an E‑E‑A‑T perspective, a shop should publish reliable product descriptions (ideally written by someone who has used the product) and avoid misleading information. In addition, authority can be built through a topical blog and collaboration with well-known influencers – a recommendation from a recognisable person increases trust in the shop.

Finance: Here expertise and authority come first, and the whole subject area is YMYL. Content about finance and investing should be created or reviewed by licensed advisers, economists or lawyers. It’s essential to disclose the authors’ qualifications (degrees, professional certificates) and cite sources (e.g. links to official reports from banks or regulators). Authority is also built through links with institutions – appearing at industry conferences, being quoted by financial media or guest posting on economics portals. Trust grows when you present clear investment rules and transparent fees – clients want to be sure nobody will mislead them. It’s worth publishing testimonials from real clients and educational articles that explain difficult topics in plain language.

Construction (including modular homes): In this niche, experience and the client’s trust in the contractor are very important. Developers and modular building companies build E‑E‑A‑T by documenting their projects – a portfolio with step-by-step descriptions, video reports from the build or reviews from clients. Expertise is shown by publishing advice from designers and engineers (e.g. how to prepare a plot for a house) and sharing quality certificates for materials. Authority in construction is confirmed by recommendations from satisfied clients and a presence in the trade press or business directories. Trust is further strengthened by a clear quality guarantee and realistic deadlines – clients will appreciate a detailed work schedule and physical documentation (photos, technical drawings). A construction company’s website should have comprehensive contact details and location information, which confirms its credibility.

Tourism and travel: One example is a travel blog or a hotel website, where the author’s expertise and experience count. Articles written by seasoned travellers (with years of trips behind them) or hotel staff (a manager from the industry) gain credibility. Authority is built by recommendations in travel guides or awards received (e.g. Travellers’ Choice on Tripadvisor). Trust is strengthened by detailed descriptions of places, reliable advice (e.g. on travel safety) and genuine photos and accounts from users. Good guest reviews on independent platforms (Booking.com, Google) encourage further customers.

Frequently asked questions about E‑E‑A‑T

Is E‑E‑A‑T a ranking factor?

Not directly. Google writes that E‑E‑A‑T itself isn’t a specific ranking factor, but its systems use a mix of factors that help identify content with good E‑E‑A‑T. So you can’t ‘switch on’ E‑E‑A‑T with a single setting – it’s the result of content quality and the site’s reputation.

What’s the difference between E‑A‑T and E‑E‑A‑T?

E‑E‑A‑T is an extended version of E‑A‑T. In December 2022 Google added ‘Experience’ to the guidelines, meaning first-hand experience – e.g. actually using a product or visiting the place you’re writing about.

Can content written with the help of AI have good E‑E‑A‑T?

It can, but the tool alone won’t provide experience or trust. The rater guidelines say generative AI can be used to create both high-quality and lowest-quality content. The lowest ratings go to pages produced at scale with no originality or added value. AI-assisted content should therefore have a real author, checked facts and first-hand experience that a model can’t generate.

Does E‑E‑A‑T only apply to YMYL sites?

No. The E‑E‑A‑T criteria apply to all content, but for YMYL topics (health, finance, safety, public affairs) the bar is highest. According to the guidelines, most topics aren’t YMYL and don’t require such a high level of accuracy and trust.

Where should you start improving E‑E‑A‑T on your site?

With the basics of trust: clear information about who is behind the site (an ‘About us’ page, contact details, company details), named authors with a short bio, and up-to-date, fact-checked content. After that, it’s worth reviewing your existing articles and adding your own experience, examples and sources – this is where content optimisation helps.

Finally…

E‑E‑A‑T is a concept that lets you assess and improve a website’s credibility. Applying its principles means creating valuable content written by real experts and building a solid brand reputation. The key goal is users’ trust – earned through proof of experience, backed-up knowledge, recognition from authorities and the site’s reliability. To improve your site’s E‑E‑A‑T, focus on high-quality content, share information about your authors, collect reviews and use monitoring and analysis tools. Whatever your industry (e-commerce, finance, construction or anything else), solid E‑E‑A‑T foundations will help you stand out in search and win the trust of both Google and your visitors.
