The four components of E-E-A-T explained
Google's Search Quality Evaluator Guidelines define each component precisely. Understanding the distinction between them — particularly between Experience and Expertise — is essential for knowing which signals to build.
Experience
Added December 2022
The content creator has first-hand, real-world experience with the topic. A product review written by someone who has actually used the product. A medical article written by a practitioner who has treated the condition. A financial guide written by someone who has navigated the process personally.
How to build it
Case studies, 'From Our Work' sections, specific outcomes with real numbers, practitioner observations, corrections and recoveries — content that only someone who has done the work could produce.
Expertise
Original E-E-A-T component
The content creator has formal or demonstrable knowledge of the subject. Qualifications, certifications, professional credentials, or a verifiable track record of work in the field. Expertise is about what you know; Experience is about what you have done.
How to build it
Author bios with verifiable credentials, professional certifications, published work, speaking engagements, industry recognition, structured data (Person schema with credentials).
Authoritativeness
Original E-E-A-T component
The content creator and the website are recognised as authoritative sources by others in the field. Authoritativeness is an external signal — it is not claimed, it is conferred by others through citations, backlinks, mentions, and references.
How to build it
Editorial backlinks from authoritative industry sources, mentions in trade publications, citations by other experts, featured snippets, knowledge panel entries.
Trustworthiness
Original E-E-A-T component — the most important
The website and its content are honest, accurate, and safe. Google's guidelines describe Trustworthiness as the most important of the four components — a site can have high Experience, Expertise, and Authoritativeness but still be untrustworthy if it is deceptive, inaccurate, or harmful.
How to build it
Accurate factual claims, clear authorship, transparent business information (address, contact, About page), HTTPS, privacy policy, no deceptive patterns, positive reviews and reputation signals.
Why E-E-A-T matters more for some topics than others
Google applies E-E-A-T evaluation most stringently to what it calls YMYL — Your Money or Your Life — topics. These are topics where low-quality content could directly harm the reader: medical advice, financial guidance, legal information, safety instructions. For YMYL topics, the bar for E-E-A-T is extremely high; content from unqualified sources will not rank regardless of its technical SEO quality.
For non-YMYL topics — product reviews, travel guides, hobby content, general business advice — E-E-A-T still matters, but the threshold is lower. The practical implication is that a freelance SEO consultant writing about SEO strategy is held to a different standard than a non-medical site writing about health conditions. Know your topic's YMYL classification and calibrate your E-E-A-T investment accordingly.
| Topic type | YMYL level | E-E-A-T requirement |
|---|---|---|
| Medical / health advice | High | Formal medical credentials required; authored by or reviewed by qualified practitioners |
| Financial / legal advice | High | Professional qualifications (FCA, SRA, ACCA) required; regulated content standards apply |
| Safety information | High | Authoritative sources only; no unverified claims |
| Professional services (SEO, marketing, consulting) | Medium | Demonstrable track record, case studies, verifiable credentials |
| Product reviews | Medium | First-hand use of the product; specific observations that only a user could make |
| General how-to content | Low–Medium | Practical accuracy; some first-hand experience adds value but is not mandatory |
How to build E-E-A-T: the practical actions
Add genuine first-hand experience to every article
HighestThe Experience component is the most recently added and the most commonly absent. Every article should contain at least one element that only someone who has done the work could produce: a specific outcome, a pattern observed across multiple clients, a decision made with reasoning, or a correction after something went wrong. This is the 'From Our Work' section that distinguishes non-commodity content.
Build complete author profiles with verifiable credentials
HighEvery article should have a named author with a bio that includes verifiable credentials — professional qualifications, years of experience, specific areas of expertise, and links to a profile page or LinkedIn. Author schema (Person type with hasCredential and knowsAbout properties) makes these credentials machine-readable for Google.
Earn editorial backlinks from authoritative sources
HighAuthoritativeness is conferred by others. The most effective way to build it is to produce content that authoritative sources in your industry cite, link to, or reference. This requires content that is genuinely useful, original, or data-driven — not content that merely covers the same ground as existing resources.
Complete and accurate business information
MediumTrustworthiness requires that your site's business information is complete, accurate, and consistent across all platforms. This means: a detailed About page, a real contact address and phone number, consistent NAP (Name, Address, Phone) across Google Business Profile, directories, and your site, and an up-to-date privacy policy.
Add structured data for author and organisation
MediumPerson schema with sameAs links to LinkedIn, Twitter/X, and other professional profiles makes author credentials machine-readable. Organization schema with address, contactPoint, and sameAs links to Google Business Profile and Companies House makes business legitimacy verifiable. These are not ranking factors in isolation, but they make your E-E-A-T signals accessible to Google's systems.
From our work
The most consistent E-E-A-T gap in content audits for professional services businesses is the absence of the Experience component. The content is technically accurate and well-structured, but it reads as if it could have been written by anyone who researched the topic — there is no practitioner voice, no specific outcome, no pattern observed across real client work. Adding a single "From Our Work" section to each article — a specific, anonymised observation from actual engagements — consistently improves engagement metrics (time on page, scroll depth) and, over a 60–90 day window, produces measurable improvements in rankings for articles in positions 11–30. The Experience component is the lowest-cost, highest-impact E-E-A-T improvement available to most professional services sites.
Frequently asked questions
What does E-E-A-T stand for in SEO?
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It is the framework Google's human quality raters use to evaluate the quality of web pages, as described in Google's Search Quality Evaluator Guidelines. Google added the first 'E' for Experience in December 2022.
Is E-E-A-T a direct Google ranking factor?
E-E-A-T is not a direct algorithmic ranking factor in the sense that there is no single 'E-E-A-T score'. However, the signals that constitute E-E-A-T — author credentials, site reputation, content depth, backlink profile, structured data — are all inputs into Google's ranking systems.
How do I improve E-E-A-T for my website?
The highest-impact improvements are: adding genuine first-hand experience to content, building author profiles with verifiable credentials, earning editorial backlinks from authoritative sources, completing your business information, and adding structured data for author and organisation.
