Google updated its quality rater guidelines in December 2022, changing its well-known content quality acronym from E-A-T to E-E-A-T.
E-A-T used to stand for Expertise, Authoritativeness, and Trustworthiness, before Google added the new “E,” which stands for experience. Meaning E-A-T is now E-E-A-T: Experience, Expertise, Authority, and Trustworthiness.
The emphasis is on content quality, as you might expect.
