E-E-A-T
Experience, Expertise, Authoritativeness, Trustworthiness
E-E-A-T refers to the criteria Google uses to judge the quality of content and its author: experience, expertise, authoritativeness, and trustworthiness.
This isn't a direct ranking factor but an evaluation framework, especially for sensitive topics: health, finance, safety. Google looks for concrete signals: an identifiable author, cited sources, demonstrated experience.
For a business site, this means clear author pages, real case studies, and content that shows hands-on practice with the subject rather than a simple rewrite.
