In plain English
A quality-evaluation framework covering experience, expertise, authoritativeness and trust—not a single score or guaranteed ranking factor.
Why it matters
This term helps you assess recognition and credibility without reducing SEO to a promise or a single number.
Example
A health article shows its clinician reviewer, sources, update history and responsible publisher details.
Common misunderstanding
Context matters. This concept does not guarantee rankings and should not be used to justify manipulative link building.
