Definition
These criteria come from the guidelines Google provides to its quality raters (Search Quality Rater Guidelines). The first "E," for experience, was added in December 2022. Google clarifies that E-E-A-T is not a direct ranking factor, but a framework that describes what its systems aim to reward.
How it works
In practical terms, content demonstrates experience when it is based on real-life involvement (a project, a client case), expertise when the author has mastered their subject, authority when other recognized sources mention it, and trustworthiness when the information is accurate, sourced, and transparent.
Why it matters for your site
For an agency, a firm, or a software publisher, these are exactly the signals a prospect looks for before reaching out to you: who is writing, on what basis, and with what evidence. Generative AI also prioritizes reliable and verifiable sources.
The We-R perspective
E-E-A-T cannot be "checked off" with a tag. It is built through identified authors, quantified client cases, sourced data, and a brand that is talked about elsewhere. That is why our articles cite their sources and our client cases provide measured results.

Have questions?
Transparency for informed decision-making.
Not directly, according to Google. It is a quality assessment framework reflecting what its algorithms aim to reward.
With detailed case studies, real examples in articles, team photos and named authors with their background.
AIs more readily cite reliable, sourced sources that are recognized elsewhere. The same signals therefore serve both Google and GEO.
