E-E-A-T is an acronym for Expertise, Authoritativeness, Trustworthiness, and Expertise. It is an expanded version of the E-A-T concept that was introduced in the Google Search Quality Evaluator Guidelines and is used by Google's algorithm to evaluate the quality of a website and its content.
Expertise refers to the level of knowledge or skill that an individual or organization has in a particular field or industry. For example, a medical website should be written by medical professionals who have the necessary expertise to provide accurate and reliable information.
Authoritativeness refers to the perceived level of authority that an individual or organization has in a particular field or industry. This can be based on factors such as reputation, credentials, awards, and endorsements. For example, a legal website may be considered more authoritative if it is run by a well-respected law firm.
Trustworthiness refers to the perceived level of trust that users have in an individual or organization. This can be influenced by factors such as transparency, accountability, and user experience. For example, a financial website may be considered more trustworthy if it provides clear and transparent information about its sources of funding and its investment practices.
Expertise, emphasizes the importance of demonstrating a high level of expertise not only in the main content of a website but also in supplementary content such as forums, user-generated content, and comments sections.
