What are the differences in the weight of the E-E-A-T principle among different search engines (such as Google and Baidu)?

When evaluating content quality, Google and Baidu have significant differences in the weight allocation of the E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) principles. Google places more emphasis on Experience and Expertise, highlighting the practical experience and domain depth of content creators; Baidu, on the other hand, attaches greater importance to Authoritativeness and Trustworthiness, showing a higher preference for content with official endorsements and institutional qualifications. In specific scenarios: Google: Prioritizes whether the content is based on real experience (such as personal cases, actual measurement data), and the professional depth needs to match the search intent. For example, tech-related content places more emphasis on technical details and practical verification. Baidu: In fields such as healthcare and finance, the review of qualification certifications (such as medical institution licenses, financial licenses) is stricter, and content endorsed by authoritative media or governments is more likely to receive higher weight. For optimization, it is recommended to adjust the focus according to the target search engine: for Google, increase descriptions of the creator's experience and professional analysis; for Baidu, strengthen institutional qualifications and citations of official information.
