What are the evaluation criteria for E-A-T (Expertise, Authoritativeness, Trustworthiness) on international mainstream platforms?

International mainstream platforms typically evaluate E-A-T based on three core dimensions: expertise, authoritativeness, and trustworthiness. Specific criteria may vary slightly depending on platform characteristics, but the overall focus is on content quality and informational value. Expertise: Primarily assesses the content creator's professional background (such as education and professional qualifications), content depth (whether it is based on domain knowledge), and relevance to the topic. Authoritativeness: Considers the industry recognition of the content source (e.g., being cited by authoritative institutions) and the creator's influence in the field (e.g., industry contributions or honors). Trustworthiness: Focuses on information accuracy (fact-checking,标注 of data sources), transparency (author identity, disclosure of利益关联), and the timeliness of content updates. Optimizing E-A-T can start with clarifying the creator's qualifications, citing authoritative sources, and regularly updating content to enhance the content's credibility and visibility on the platform, helping information reach the target audience more accurately.
