Google Search Quality Rater Guidelines

The Google Search Quality Rater Guidelines are a massive, publicly available document (over 160 pages) used by thousands of human evaluators contracted by Google to manually assess the quality of search engine results. While these human raters do not directly influence the algorithmic ranking of a specific URL, their feedback is used as the primary training data for Google’s machine learning algorithms. The guidelines are the definitive source of truth for SEO strategy; they explicitly define exactly what Google considers high-quality content, heavily emphasizing the E-E, A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) and the concept of “Needs Met.”
