Google Search Quality Rater Guidelines: Content Overview
The Google Search Quality Rater Guidelines define evaluation criteria that human quality raters (Search Quality Raters) apply when assessing search results. The document is structured into sections on Page Quality Rating, Needs Met Rating, and the classification of search queries.
A central element is the E-E-A-T evaluation framework (Experience, Expertise, Authoritativeness, Trustworthiness). E-E-A-T was defined within the Guidelines as a criteria set for assessing page quality. E-E-A-T is not a direct ranking factor of the Google search algorithm but an evaluation framework applied by human quality raters. Rater evaluations serve as a feedback signal for search quality assessment but do not directly influence the ranking of individual pages.
The document defines YMYL topics (Your Money or Your Life) as content categories where inaccurate information may have potentially harmful consequences. The YMYL classification covers health, finance, safety, and since September 2025 explicitly elections, institutions and trust (YMYL Government, Civics and Society).
