# EAT

Expertise, Authoritativeness, Trustworthiness — the three-letter pre-2022 version of E-E-A-T; Google added the "Experience" dimension to this framework in 2022.

**EAT (Expertise, Authoritativeness, Trustworthiness)** is the three-letter quality framework used in Google’s quality rater guidelines between 2014 and 2022. In December 2022, Google also added the “Experience” dimension to the guidelines, changing the term to [E-E-A-T](/content/sozluk/e-e-a-t/index.html).

The three core pillars of EAT:

- **Expertise (Expertise):** The content creator has deep knowledge of the subject.
- **Authoritativeness (Authority):** The author and the site are recognized references in the industry.
- **Trustworthiness (Trustworthiness):** The information is accurate, up to date, and verifiable.

EAT still appears in many SEO documents; however, in modern practice, the E-E-A-T framework (with experience added) should be used.

**Tip:** All recommendations in older sources that mention EAT also apply to E-E-A-T; only the “experience” dimension has been added.
