EAT is an acronym that stands for "Expertise, Authoritativeness, and Trustworthiness," which are some of the top principles Google uses to evaluate the quality of webpages. It is most often used by web content creators and SEO professionals.

The EAT acronym was coined by Google as a guideline for web content creators to follow in order to become a high ranking website that would also rank well on SERPs. In August 2018, Google released an update to its search algorithm known as "the medic update," which emphasized the EAT principles, leading every SEO enthusiast to become obsessed with the acronym.
