Delving deeper, it discusses how to boost page relevance through content updates, content differentiation, and semantic SEO, avoiding keyword stuffing and enhancing search engines' understanding, ensuring that pages have an advantage in long-tail keywords and competitive areas.

By using accurate Hreflang tags, it achieves precise matching across countries/languages, ensuring that users in the global market have a good search experience.
  • User Behavior and Interaction Optimization
    User behavior's impact on SEO is increasingly significant. The book discusses in detail how to utilize user behavior data to optimize SEO, increasing click-through rates (CTR) and dwell time. By utilizing user-generated content (UGC) and user feedback, it enhances the website's interactivity and content quality, further improving SEO performance.
  • Structure and SEO Audit
    No matter the size of the website or the length of the page, optimizing page structure is crucial. This book discusses not only how to optimize through data-driven SEO strategies but also introduces how to use SEO audit tools for comprehensive SEO checks, ensuring that the website always complies with the latest SEO best practices.
