What is E-E-A-T? How does it help me?

Most of the sites I audit that are struggling to rank have decent content. The problem is usually that Google doesn’t trust the source. E-E-A-T is Google’s framework for assessing whether it should. Get it wrong and it doesn’t matter how well-written your pages are.

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It comes from Google’s Search Quality Evaluator Guidelines, the internal document Google’s human raters use to assess whether a page deserves to rank. For most sites it’s a background signal. For health, finance, and legal content, it’s make or break.

1. Experience

Experience means firsthand involvement with the subject. Google added this fourth E in December 2022 specifically because it was seeing too much content written by people who had clearly never done the thing they were writing about. A guide to fixing drain blockages written by someone who has never touched a drain. A review of accounting software written by a content mill with no accounting background. Technically competent writing that completely lacks the texture of someone who has actually been there.

In practice, experience shows up in specifics. When I write about technical SEO audits, I reference actual patterns I see in crawl data, specific error combinations that tend to appear together, and the order I work through issues based on what causes what. That is not something you can fake convincingly at scale. Google’s systems, and human quality raters, are increasingly good at distinguishing content that could only have come from direct involvement versus content assembled from other sources.

For your site, experience signals include: first-person accounts of processes you have actually completed, case studies with real outcomes and specific numbers, screenshots and examples from your own work, and details that are only meaningful to someone who has done the job. A before-and-after crawl error report from a real client audit demonstrates experience in a way that a definition of what a crawl error is does not.

The gap between sites with strong experience signals and those without has widened materially since 2023. If your content reads like it was assembled rather than written from a position of doing the work, that is the single most important thing to address.

2. Expertise

Expertise is formal knowledge, qualifications, credentials, professional background. For YMYL content it is non-negotiable. A medical information page needs to be written or reviewed by someone with medical credentials. A tax advice page needs a qualified accountant behind it. Google’s quality raters are explicitly instructed to look for evidence of professional credentials on health, finance, and legal pages, and to mark pages without them down regardless of content quality.

Outside YMYL, expertise is more contextual. A plumber writing about drain systems does not need a degree, but they do need demonstrable professional knowledge that goes beyond what a homeowner would know. A software developer writing about API integration does not need a computer science qualification, but their content should reflect genuine technical depth. The question Google is trying to answer is whether this person is genuinely qualified to give this information, not whether they have a formal credential for it.

The most common expertise gap I see on small business sites is anonymous content. Pages with no author attribution at all, written in a generic third-person voice, with no indication of who is behind the words. That is not a minor issue. It is the clearest possible signal that the site is not investing in expertise, because if they were, they would want that expertise visible.

Fix: every content page needs a named author with a bio that describes their relevant background. Not just a name. A bio that explains what makes them qualified to write this specific piece. For a single-person business this is straightforward, it is you, and your bio should cover your professional history, any relevant qualifications, and ideally a link to a more complete About page.

3. Authoritativeness

Authority is relative, not absolute. A local solicitor does not need to be cited in the Financial Times to be authoritative on family law in Bath. They need to be recognised as an authority within the context where people search for that information. That context might be local press, professional directories, mentions in local business associations, or links from other legal sites. What matters is that sources beyond their own site are validating their expertise.

This is where traditional SEO link-building and E-E-A-T overlap most directly. A backlink from a respected source in your industry is not just a ranking signal, it is an authority signal that tells Google this entity is recognised by others who know the space. A Clutch profile with real client reviews and a DR91 link is authority evidence. A mention in a relevant trade publication is authority evidence. A citation from a professional body in your field is authority evidence.

The off-site signals that build authority in Google’s eyes: coverage in respected publications relevant to your niche, citations and mentions by other authoritative sources in your industry, a Google Business Profile with a genuine review history, listings in professional and industry directories, and being the source other sites link to when they need to reference someone credible on your topic. None of these require national press coverage. They require being genuinely recognised within your specific domain.

Author-level authority matters separately from site-level authority. A well-known SEO professional writing a guest post on a new domain brings their authority with them. A junior content writer producing pages for an established domain does not inherit the site’s authority. Google is increasingly distinguishing between these two situations, which is another reason why attribution matters.

4. Trustworthiness

Trustworthiness is the foundation of the other three. Google’s quality guidelines are explicit: a page can have demonstrated experience, clear expertise, and recognised authority, and still rank poorly if it cannot be trusted. Trust issues can contaminate an otherwise strong E-E-A-T profile at the site level, not just the page level.

HTTPS is baseline infrastructure, not a trust signal. If your site is still on HTTP in 2025 that is a technical problem to fix immediately, but fixing it will not move your rankings. The trust signals that actually matter in the current environment are transparency, accuracy, and consistency between what you say and what you deliver.

Transparency signals: a real About page with identifiable people, a physical address or clear geographic context, a working contact method, and visible authorship on content. Accuracy signals: factual claims that can be verified, sources cited where relevant, content that is updated when information changes, and no misleading or exaggerated claims. Consistency signals: your business description matching your actual services, your reviews matching your stated positioning, and your content matching your evident expertise.

The trust signal I see most commonly missing on small business sites is a credible About page. Not a paragraph saying “we are passionate about our work.” An About page that tells the actual story of the business: who founded it, their background, what they have done, who they have worked with, and why that qualifies them to do what they do. Google’s quality raters spend disproportionate time on About pages when assessing trust. Most small business About pages are the weakest page on the site.

For YMYL content specifically, trust also means making it clear when information was last verified, who reviewed it, and what the scope of your advice is. A solicitor’s blog post should note the date and clarify that it is general information rather than legal advice for a specific situation. Not because of legal liability, because that transparency is a trust signal.

How to audit your own E-E-A-T

Before looking at anything technical, read your own site as if you have never seen it before. Ask yourself: if I landed on this page with no prior knowledge of this business, would I trust this person to give me reliable information? Would I know who wrote this and why they are qualified to write it? Would I be confident enough to act on what they are saying?

Most sites fail that test on at least two of the four dimensions. Here is how to diagnose where your gaps are.

Check your author attribution. Go to your five most important content pages. Does each one have a named author? Does the author bio describe relevant experience and qualifications specific to that topic? If you have anonymous pages, that is your first fix, not a technical one, a content decision that costs one afternoon to address across most sites.

Check your About page. Does it name real people? Does it describe their specific backgrounds and relevant experience? Does it include any verification of claims, professional memberships, credentials, notable clients? A weak About page undermines every other E-E-A-T signal on the site. It is the single page that quality raters spend the most time on when assessing whether to trust a site.

Check your off-site citations. Search for your name and your business name. Are you mentioned anywhere beyond your own site? Local directories, industry publications, professional bodies, press coverage, client case studies on other sites? If the answer is no, your authority signals are entirely self-asserted. That is not sufficient for competitive queries in most niches.

Check your content for specificity. Can you find five examples across your site where you describe something in enough detail that it could only come from direct involvement? Numbers, outcomes, specific processes, tools used, problems encountered? If your content is entirely general and could have been written by someone who has never done the work, that is an experience gap.

Check for accuracy signals. Do any of your pages contain claims that are no longer accurate? Statistics from several years ago, products or services that have changed, guidance that predates significant developments in your field? Outdated content is a trust signal in the wrong direction, and it compounds over time as the gap between what you publish and what is currently true widens.

If you want a structured assessment of how your site’s E-E-A-T signals compare to competitors ranking above you, that is something I look at as part of a technical SEO audit. The gap is usually identifiable and fixable, it just requires someone to do the work honestly rather than producing more content that repeats the same weaknesses.

What has changed with E-E-A-T since 2023

E-E-A-T itself has not changed. The framework is the same. What has changed is how seriously Google enforces it, and which signals it can now reliably detect at scale.

The September 2023 helpful content update was the first time I saw sites with genuinely good content lose rankings simply because Google could not verify who was behind it. Anonymous, unattributed content on legitimate topics, that was the category that got hit hardest. Not spam. Not AI slop. Credible-looking sites with no identifiable author and no evidence of real-world expertise behind the pages.

Here is what fixing it looked like on one site. Pharmacy Price Hound compares medicine prices, which puts it squarely in YMYL territory where Google applies the strictest scrutiny. In the final week of August 2025 it generated 32 clicks at an average position of 66. We rebuilt the E-E-A-T signals, the schema and the page structure at the same time rather than in sequence. By the week of 24 November it was generating 628 clicks at an average position of 8.11. Monthly clicks went from 98 to 2,183 and impressions from 11,422 to 109,427, over three months. The dip through September is normal after structural work, and it recovered sharply once Google had recrawled.

Since then the pattern has been consistent. Each core update has tightened enforcement around the same signals: who wrote the content, what qualifies them to write it, and whether other authoritative sources agree with their existence. The August 2024 update recovered some of the sites hit in 2023, specifically the ones that had genuinely fixed those attribution gaps rather than just adding a fake author name to a bio page.

AI content is the obvious topic here and the answer is more straightforward than most coverage suggests. Google does not penalise AI-assisted content. It penalises content that is unoriginal, unattributed, and adds nothing to what already exists. If your AI-assisted content reads like it could have been written by anyone about anything and it does not have a credible person attached to it, that is the problem, not the tool used to produce it.

The other material change is that E-E-A-T scrutiny is no longer limited to YMYL categories. Health and finance remain the highest bar. But I have seen clear E-E-A-T-related ranking suppression on home services sites, B2B software sites, and local businesses. If your site is in a category where someone could make a bad decision based on incorrect information, Google is applying pressure. That covers more sectors than most people realise.
