E-E-A-T
Google's shorthand for Experience, Expertise, Authoritativeness and Trust: the signals that make content credible enough to rank.
In depth
What it really means
E-E-A-T is not a ranking factor you can switch on. It is the framework Google’s human quality raters use to judge whether content deserves to be trusted, and those ratings train the systems that do the actual ranking.
One correction worth making, because most explanations get it wrong: the four signals are not equal. Section 3.4 of Google’s Search Quality Rater Guidelines states that Trust is the most important member of the family, and that an untrustworthy page has low E-E-A-T regardless of how experienced, expert or authoritative it appears. Experience, Expertise and Authoritativeness are inputs. Trust is the output.
The four signals, in their actual hierarchy
| Signal | What it asks | Cheapest proof |
|---|---|---|
| Experience | Has the author actually done this? | Original screenshots, your own test data, dated results |
| Expertise | Do they have real depth? | Named author, credentials, a body of work on the topic |
| Authoritativeness | Do others treat them as a source? | Citations, mentions, links from recognized sites |
| Trust | Is the site and the information reliable? | Accurate claims, visible contact details, honest disclosures, corrections |
Trust sits at the centre. The other three feed it. A page can be all three and still score low if it is not trustworthy.
The self-audit
Score each page out of 8. Two points each: named author with a real bio and a track record; at least one piece of first-hand evidence you produced; at least two citations to primary sources; and every factual claim currently correct. Under 5 out of 8 on a commercial page is where problems start.
Pros & cons
Pros
- The same signals that satisfy raters make AI engines comfortable citing you, so the work pays twice.
- It is durable. Unlike tactical SEO, credibility does not get devalued by the next update.
- It forces the fix that helps most anyway: put an actual expert’s name and experience on the page.
Cons
- Not directly measurable. There is no E-E-A-T score to watch, which makes progress hard to report.
- Slow. Authority accumulates over quarters.
- Easy to fake badly. Stock-photo author bios and invented credentials are worse than no byline.
The mistake people make
Treating E-E-A-T as a checklist of on-page elements. Adding an author box to a page written by nobody in particular does not create expertise, it advertises the absence of it. The fix is upstream: get the person who actually knows the subject to contribute the parts only they could write, even if a writer shapes the rest.
Best practices
- Put a real, findable author on every piece, with a bio that names what they have done.
- Show first-hand experience: your own data, your own screenshots, your own results with dates.
- Cite primary sources and link out. Outbound links to authoritative documents are a trust signal, not a leak.
- Keep pricing, claims and statistics current, since a wrong fact is a trust failure.
- Earn mentions from recognized sites in your category.
- Fix the fundamentals: visible contact details, secure site, clear ownership, published corrections.
FAQs
Is E-E-A-T a ranking factor?
Not a single switch. It is the framework raters use, and rater data trains the systems that rank. The effect is real and indirect.
What did the extra E add?
Experience, added in December 2022, rewards first-hand knowledge. A review by someone who used the product outranks a summary of other reviews.
Does E-E-A-T matter for every topic?
Everywhere, and most on your-money-or-your-life topics like health, finance and safety, where raters apply the strictest standard.
How do I improve E-E-A-T?
Real authors with real experience, accurate facts, primary citations, and earned mentions. In that order.
Does E-E-A-T affect AI answers?
Yes, indirectly and strongly. The credibility signals that satisfy raters are close to what makes a source safe for a model to cite.
