E-A-T is a page quality ranking that stands for expertise, authoritativeness, and trustworthiness within the realm of search engine optimization. E-A-T is specifically listed in Google’s Quality Rater Guidelines (QRG), which assesses the quality of search results and whether website pages pass inspection to be displayed on search engine results pages (SERPs). Even though Google typically reviews at a page level and ranks sites per page, the overall authority of the entire site can help individual pages to rank higher.
