The claim
Demonstrable experience, expertise, authoritativeness and trust improve how content is assessed, especially for high-stakes topics.
What the evidence shows
Google's publicly released Quality Rater Guidelines instruct human raters to evaluate content using E-E-A-T, with Trust as the most important member, and apply the highest bar to Your Money or Your Life topics. While raters do not directly set rankings, the guidelines describe the quality Google's systems are built to reward. Clear authorship, credentials and trust signals are central to that assessment.
