Psychometrics & Testing
E-E-A-T (Google Quality Signal)
Experience, Expertise, Authoritativeness, Trustworthiness — Google's framework for content quality evaluation. Critical for health and psychology content.
E-E-A-T determines whether Google considers content worthy of ranking, especially for YMYL (Your Money or Your Life) topics like personality testing and mental health.
Experience: Has the author experienced what they write about? Expertise: Deep demonstrated knowledge? Authoritativeness: Recognized in the field? Trustworthiness: Accurate, transparent, safe?
JobCannon builds E-E-A-T through: citing peer-reviewed research (Costa & McCrae, Holland, Goleman), linking to authoritative sources (APA, NHS, WHO), methodology pages, and clear disclaimers on screening tools.
