E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) represents a new standard for content quality evaluation that Google is increasingly demanding. SEO leaders recommend showcasing specific experience and expert authorship (for example, through biographies, links to published works, or personal experiences in the field), which increases trust. Algorithms increasingly penalize unclear and anonymous sources. In practice, E-E-A-T means the need for verifiable reviews, references, citations, and personal expertise from each author.
