E-A-T, an abbreviation for Expertise, Authoritativeness, and Trustworthiness, represents a crucial set of criteria utilized by search engines, notably Google, to assess the quality and credibility of online content.

Expertise refers to the depth of knowledge and proficiency displayed by content creators or websites in specific subjects, often demonstrated through qualifications and experience.

Websites and content exhibiting strong E-A-T principles are more likely to rank well in search engine results, particularly for health, finance, safety, or overall well-being topics.
