III. 5 Foundational Technical Principles Mastered by SEO Optimization Experts

A true **SEO optimization expert** must fundamentally understand search engine mechanics:

Technical Application: **SEO optimization experts** must diagnose and improve **LCP, FID, CLS** core metrics through **frontend optimization, server configuration, and CDN deployment**, **integrating performance optimization into SEO workflows**.

5. Search Intent Mapping Principle

Principle: User queries conceal **four core intents (navigational, informational, commercial investigation, transactional)**. Application: The **core task of SEO optimization experts** is **precisely judging each keyword's intent**, ensuring **content type and conversion goals perfectly align with user intent**.
