Expertise, Authority, Trust (E-A-T)

What is Expertise, Authority, and Trust (E-A-T) in the context of SEO?

Expertise, Authority, and Trust (E-A-T) are essential factors that search engines like Google consider when evaluating the quality and relevance of a website’s content. E-A-T helps search engines determine the credibility and reliability of a website’s content, which can impact its rankings in search results.


Expertise refers to the level of knowledge and skill demonstrated by the content creator or website author. Authority relates to the perceived credibility and influence of the website or content creator within their industry or niche. Trust pertains to the reliability and integrity of the information provided, as well as the transparency and legitimacy of the website itself.

Example of how E-A-T works

A website providing medical advice should have content created by qualified healthcare professionals (expertise), with references from reputable medical organisations (authority), and clear citations and sources for its information (trust). By demonstrating expertise, authority, and trustworthiness, the website can improve its search engine rankings and gain credibility with users.
