E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)

The four signals

Four stacked building blocks labeled Experience, Expertise, Authoritativeness, and Trustworthiness supporting a page that ranks near the top of search results.

The four factors

Experience. First-hand experience with the topic. For a product review, has the author actually used the product? For a how-to, have they actually done it? Real case studies, specific anecdotes, and honest "what didn't work" notes all signal experience.

Expertise. Real, substantive knowledge. Credentials help (degrees, certifications), but so does demonstrated knowledge: consistent quality across many articles, technical depth, and accurate use of the field's vocabulary.

Authoritativeness. Recognition by others. Links from authoritative sites, citations in trade publications, and mentions in adjacent expert content. This is the hardest factor to manufacture, and it builds over time.

Trustworthiness. Accurate facts and transparent sourcing: a cited source for every claim, year-stamped data, honest tradeoff sections, and clear author bylines. Of the four, this is the one most directly within an author's control on any given piece.

Why E-E-A-T became a primary ranking factor

The January 2026 Core Update moved E-E-A-T from "considered alongside other signals" to a primary ranking factor for YMYL (Your Money, Your Life) topics and, increasingly, general ones. The driver: AI-generated content flooded the web in 2024-2025, and Google's ranking models shifted toward signals that such content struggles to fake, including:

• Named human authors with verifiable identities
• First-hand experience told with specific detail
• Links from authoritative, human-curated sites
• Honest "what didn't work" sections

How operators ship E-E-A-T

A few concrete moves:

1. Bylined authors. Every article signed by a real person with an /authors/{slug} page, Person schema, and links to LinkedIn, X, or GitHub.
2. First-hand experience. Cite specifics; "April-May 2026, 30-day holdouts" beats "we measured an improvement."
3. Honest tradeoffs. Every page names a failure mode or limitation.
4. Source-named claims. Every factual claim names its source and year.
5. Deep author profiles. Photo, bio, history, social links, and a list of published work.
6. Authoritative backlinks. This accrues over time and isn't a same-day fix.
