E-E-A-T. Four letters Google rewards. Twelve on-page signals you can ship this week.

What E-E-A-T actually means

E-E-A-T is the acronym Google uses inside its Search Quality Rater Guidelines: a 170-page document Google publishes for the thousands of contracted human raters who score search results around the world. Those raters do not directly affect the algorithm. They score sample SERPs. The algorithm engineers then tune the systems to better match the raters' scores. So the framework is one step removed from the algorithm, but it is the closest formal description of what Google considers "good" content.

The four letters stand for:

• Experience. Has the author actually done the thing they are writing about? First-hand use of a product, first-hand visit to a location, first-hand work in a field. Added to the framework in December 2022.
• Expertise. Does the author have genuine knowledge of the subject? Formal qualifications, real-world track record, or demonstrable depth in the area.
• Authoritativeness. Is the site or author recognised as a credible voice on this topic? Mentions and links from other authoritative sources, industry recognition, named involvement in the field.
• Trust. Is the site itself trustworthy? Verified business identity, transparent policies, secure HTTPS, accurate citations, fair treatment of readers. Trust sits at the centre of the framework. Google's own raters guidelines call it the "most important" of the four.

The four are layered. Experience and Expertise are about the author. Authoritativeness is about how others view that author and the site. Trust is the overall judgement on the business behind the page. None of them are checkboxes you tick once. They are signals that accumulate across hundreds of small decisions on every page.

Why it matters more in 2026

Two shifts have made E-E-A-T more important since 2022.

The Helpful Content Update. Google's run of core updates since August 2022 have explicitly targeted pages that lack signs of genuine expertise. Sites that built traffic on thin, scaled, unsigned content have been hit hard. Sites with named authors, real credentials and dated reviews have largely held up. The pattern is consistent enough that we now treat E-E-A-T signals as a core part of any audit.

The AI content boom. Tools like ChatGPT made it trivial to generate plausible-looking articles at scale. Google's response has been to lean harder on signals that AI cannot easily fake: real photographs of real people, named case studies with named clients, dated personal experience, verified business addresses. AI can produce the text. It cannot produce a 20-year track record. E-E-A-T is increasingly the line between content Google trusts and content it does not.

This is not an anti-AI position. We use AI as a drafting tool ourselves. The point is that the published page needs to show human signals, regardless of how it was drafted.

YMYL: where E-E-A-T matters most

YMYL stands for "your money or your life". It is Google's shorthand for any topic where bad information could materially harm a reader. The category includes:

• Financial topics (investing, mortgages, tax, insurance).
• Health and medical topics (treatments, medications, diagnoses).
• Legal topics (contracts, family law, immigration).
• Safety topics (industrial safety, electrical work, food handling).
• Civic topics (voting, government services, news).
• Some big-purchase consumer topics (cars, homes, education).

If your business operates in any of these, your E-E-A-T scrutiny is much higher than a homewares retailer's. A Perth-based financial planner with anonymous blog posts will struggle to rank against one whose articles are signed by an AFSL-authorised representative with stated credentials. Same content, different authority signals, very different outcomes.

For non-YMYL topics, E-E-A-T still matters but with less weight. A craft beer review site benefits from named reviewers with photos and dates, but a missing credentials line is not the same red flag it would be on a tax-advice site.

The four letters, with on-page signals for each

Experience: showing you have done the thing

The newest of the four letters and often the easiest to nail. Signals:

• Original photographs of the author doing the work (an electrician at a panel, a chef in the kitchen, a financial planner in the office).
• Named case studies with named clients (with permission).
• First-person language: "We tested this on a Joondalup site last June", "Our team installed this on the Cockburn project in 2024".
• Specific dates and locations that anchor the story in reality.
• "Behind the scenes" content that an outsider could not fake (process photos, raw screenshots from your own tools).

If you have done the thing, say so explicitly. The number of Perth tradies whose service pages do not mention "we have completed over X jobs in [suburbs]" is staggering. Adding that line is a 90-second E-E-A-T win.

Expertise: showing you know the field

• Author byline with name, photo, and credentials.
• Author bio page with detailed background, qualifications, professional history.
• Schema markup describing the author as a Person with jobTitle and worksFor.
• Specific qualifications named in the body (e.g. "fully licensed under EC0001234" for an electrician).
• Industry body memberships named and linked (Master Builders, CPA Australia, Law Society of WA).
• Awards or recognitions where genuine.
• Years in industry stated explicitly.

Authoritativeness: showing others see you that way

• Press mentions linked from your site (logo wall on the About page, "as seen in" block).
• Inbound backlinks from recognised industry sources. See the off-page SEO pillar for the off-site half.
• Guest contributions to recognised industry publications, linked back from your site.
• Speaking engagements, conference appearances, podcasts.
• Recognised certifications or accreditations shown on the site.
• For local Perth businesses: Google Business Profile reviews with named local clients, Local Pack visibility, and industry directory listings.

Trust: showing the business is real

• HTTPS site-wide. Mixed-content warnings break trust instantly.
• Physical address visible in the footer and on the Contact page.
• Phone number visible site-wide. Same number across NAP citations.
• Verified Google Business Profile.
• ABN, ACN or relevant business identifier visible.
• Real photos of the team, the office, the work.
• Customer testimonials with names, suburbs and roles (not just initials).
• Transparent privacy policy and terms.
• No deceptive ad placement, popup spam or hidden content.
• Organization schema with verified details, sameAs links to LinkedIn, Facebook, Google Business Profile.
• Author dates: published and last reviewed, on every article.

Trust is the meta-signal. If the basics here are missing (no address, no phone, no real team photos), even strong E, E and A scores get discounted. Fix the trust signals first.

Twelve signals to ship this week

If you have a Saturday morning to dedicate, here is the prioritised list of E-E-A-T wins:

1. Add a named author byline to every blog post and key service page. Real name, real photo, real role.
2. Build out the author bio pages. Full background, qualifications, professional links.
3. Add a "Reviewed by" line and a date to every article. Pair the author with a senior reviewer where the author is junior.
4. Add Organization and Person schema to every page. The schema is invisible to readers but read by Google. See the entity SEO chapter for the full markup.
5. Add original photographs to every page. Of the team, the office, the work. Stock photos signal absence of expertise.
6. Add a credentials line on every service page that needs one ("Licensed under...", "Member of...", "Certified by...").
7. Build a logos wall of press mentions, partner bodies, or industry associations on the About page.
8. Add named case studies with a real client, suburb, problem, solution and outcome. Permission first.
9. Verify your Google Business Profile and link it from the footer. Profile reviews flow into the E-E-A-T calculus for local searches.
10. Show your physical address and phone in the footer, sitewide.
11. Publish a transparent privacy policy and terms. Trust hygiene.
12. Audit for HTTPS coverage and any mixed-content warnings.

One Saturday morning. Sustainable trust lift across the entire site. Worth more than two months of new content publishing.

A pre-publish E-E-A-T checklist

1. Author byline with name, photo, role and link to bio?
2. Published date and last-reviewed date visible?
3. Reviewer named for YMYL topics?
4. Original photos or screenshots, not stock?
5. First-person language showing real experience?
6. Real case study or named example?
7. Credentials, licence numbers or memberships stated where relevant?
8. Schema (Article, Author, Organization) valid?
9. Outbound links to recognised sources where appropriate?
10. Physical address and contact details visible site-wide?

Perth and WA context

Healthcare. Perth medical practices and allied health clinics often have generic "Welcome to our clinic" content with no author bylines. Adding the practitioner's name, AHPRA registration number, photo and bio per page is a substantial E-E-A-T lift. We worked with a Joondalup-based physio whose blog articles tripled in average position after we added named clinician bylines and AHPRA links. See healthcare SEO and SEO Joondalup.

Legal. Family law and immigration firms in Perth need explicit credentials on every article. Practising certificate, Law Society of WA membership, name of the partner who reviewed the article. Without these, Google's YMYL scrutiny pushes the page down regardless of content quality. The legal SEO guide goes deeper.

Trades and construction. Master Builders, HIA, electrical/plumbing licence numbers, public liability proof. Listing them in the footer and on every service page is a meaningful trust signal. See trades SEO for the trade-specific E-E-A-T pattern, and SEO Fremantle, SEO Cockburn for location-specific applications.

Mining services. Perth and Pilbara industrial businesses have the opposite problem. Tons of real experience, none of it documented on the website. Adding case study pages naming the commodity, the client (where permitted), the site and the outcome lifts both E (Experience) and A (Authority) substantially. See mining SEO and SEO Karratha.

Real estate. REIWA membership, agent licence number, named-agent profiles on every listing. Pages with the agent's photo and licence number outperform "anonymous" listings consistently in our tracking. See real estate SEO.
