E-E-A-T and answer engines
E-E-A-T stands for experience, expertise, authoritativeness and trustworthiness. It comes from Google's Search Quality Rater Guidelines, which added “Experience” in December 2022. It is a framework for judging quality, not a single ranking score. Showing who wrote a page, how it was made and why it exists supports it.
Where it comes from
Google’s raters use the Search Quality Rater Guidelines to evaluate results. The guidelines call trust “the most important member of the E-E-A-T family.”[1] Google added the extra “E” for experience on December 15, 2022.[2] Raters “have no control over how pages rank”; their data helps Google check that its systems work.[3] Vendor-documented
Who, How, Why
Google suggests evaluating content by asking “Who, How, and Why”:[3]
| Question | What to show | On this site |
|---|---|---|
| Who created it? | Bylines linking to author pages with credentials | AEO.wiki editorial team |
| How was it created? | Methods, testing, use of AI tools | Editorial policy |
| Why was it created? | To help people, not to game rankings | About |
Experience is the differentiator
Google’s AI guide asks for “non-commodity” content: a unique perspective or first-hand experience rather than restated common knowledge.[4] Original photos, test results, case studies and named practitioners are hard for a summarizer to get elsewhere. Vendor-documented
AI-assisted content
Google says generative AI “can be particularly useful when researching a topic, and to add structure to original content,” but generating many pages without adding value for users may violate its scaled content abuse policy.[5][6] Disclose AI assistance where readers would expect it. Vendor-documented
Practical signals
- Author bylines, bios and Person markup with
sameAs(see entity SEO). - Sources cited inline, with dates.
- Clear ownership, contact details and editorial standards.
- Accurate reviews and reputation on third-party sites (see third-party presence).
What Google says to assess in the main content
Google's people-first content guidance lists four attributes of a page's main content: the effort put into it, its originality, the talent or skill it shows, and its accuracy.[3] It states that E-E-A-T is not a specific ranking factor, that trust is the most important element, and that topics which could affect a person's health, financial stability or safety receive more weight.[3] Vendor-documented
A self-check built from Google's questions
Google gives site owners questions to ask about their own pages. Several translate directly into checks for an AEO reference page:[3]
- Does the page provide original information, reporting, research or analysis, or does it mostly restate other sources?
- Would a reader who knows the topic trust it because of the sources cited and the evidence of expertise?
- Is it clear who wrote it, how it was produced and why it exists (Google's Who, How and Why)?
- Was it produced mainly to attract search traffic, or to help people?
The same guidance lists warning signs, including content written to hit a word count, changing a date without substantially updating the page, and producing large amounts of content with automation.[3] See freshness for the date point. Vendor-documented
Authorship information must be real
Google's guidance on the "Who" question says that bylines and author information should be accurate, and that fabricating creator profiles, such as invented names or made-up credentials, is deceptive.[3] For an editorial team site, the honest option is to say so: this site credits the AEO.wiki editorial team and explains its research method and AI use on the editorial policy page, instead of inventing a named expert for each article.
Frequently asked questions
Is E-E-A-T a ranking factor?
Not as a single score. It describes what Google's systems try to reward; raters use it to evaluate results.
Can AI-written content show E-E-A-T?
Only if a person with real experience adds original insight, checks facts and stands behind it. Google judges the helpfulness of content, not how it was produced.
Does Google require an author byline on every page?
Google's guidance asks that authorship information be accurate and clear where readers would expect it, and treats fabricated author profiles as deceptive. It does not describe a byline as a ranking factor on its own.
