E-A-T stands for “Expertise, Authority, and Trustworthiness”. Google’s E-A-T guidelines are found within the Page Quality section of Google’s extensive document (129 pages!) on how their human Quality Raters should evaluate website content and search results.
While E-A-T guidelines themselves are not a direct ranking factor, they do give us significant insight into what Google is looking for when it comes to determining the quality of content on a website. We can use these insights to help guide SEO best practices for content development and to inform our strategies for building topical authority.
