Google E-A-T stands for Expertise, Authoritativeness, and Trustworthiness. It is a framework used by Google's search quality raters to assess content creators, webpages, and websites as a whole. E-A-T is particularly important for Your Money or Your Life (YMYL) topics, which could potentially impact a person's health, financial stability, or safety. High E-A-T levels indicate that a website has content created by knowledgeable professionals, is recognized as an authority in its field, and provides accurate and trustworthy information.
