In December 2022, Google updated its quality rater guidelines. Quality rater guidelines are the instructions provided to Google’s search raters, aimed at helping them evaluate the performance of Google’s search ranking systems.
While quality rater guidelines don’t directly influence ranking, they are considered by many bloggers to be useful suggestions for content creators who are trying to improve their content (both in the eyes of Google and for their readers).
Previously, these rater guidelines were governed by an acronym, EAT or E-A-T, which stood for Expertise, Authoritativeness, and Trustworthiness.
Google’s acronym has now been expanded to include a second “E” standing for Experience.
So now Google’s acronym is officially E-E-A-T, which stands for Experience, Expertise, Authoritativeness, and Trustworthiness.
You can see this change reflected in the latest search quality evaluator guidelines:
