What is the relationship between the E-E-A-T principle and content quality scoring criteria?

When evaluating content quality, the E-E-A-T principle (Experience, Expertise, Authoritativeness, Trustworthiness) is the core basis for search engine content quality scoring criteria. Experience requires content to be based on actual experiences, such as a food blogger sharing a restaurant review experience; Expertise emphasizes that creators need to have relevant professional backgrounds, such as legal articles written by practicing lawyers; Authoritativeness is reflected in the industry recognition of the content source, such as research reports published by scientific research institutions; Trustworthiness is established through accurate data citation,标注信息时效 (indicating information timeliness), etc. These elements together form a scoring framework that directly affects the ranking of content in search results. When optimizing content, E-E-A-T performance can be improved by showcasing the creator's qualifications, providing practical cases, citing authoritative sources, etc., thereby improving the quality score.
