E-E-A-T Trust Center

This hub consolidates GPACalc trust documentation for users and search engines.

What is E-E-A-T?

E-E-A-T is a quality framework from Google that evaluates web content on four dimensions: Experience, Expertise, Authoritativeness, and Trustworthiness. Sites that handle sensitive topics like education and personal academic data are held to higher standards.

GPACalc takes this seriously because GPA calculations directly affect academic planning, scholarship applications, and graduation eligibility. Incorrect results can have real consequences for students.

Below you will find links to every trust-related page on this site, organized by the E-E-A-T dimension they address. Each page is independently accessible and regularly updated.
