How to enhance the logic and readability of content through heading hierarchy design?

When title levels are designed reasonably, they can present content logic through structuring, help readers quickly grasp the information framework, thereby enhancing the logicality and readability of the content. Hierarchical order: Follow the progressive principle of H1 (main title) → H2 (core section) → H3 (sub-points), avoiding level jumps or confusion to ensure visual and logical clarity. Logical relationship: Organize titles according to structures such as general-to-specific, chronological, or cause-effect. For example, set H2 as "Problem Background", "Solution Steps", "Precautions", and H3 to further elaborate the specific operations of each step. Content relevance: Each level of title must closely focus on the core theme and avoid deviating from the main line. For instance, when discussing "SEO strategies", H2 should not include titles like "Industry Trends" that are unrelated to the theme. It is recommended to start from the core theme of the content, first plan the general framework of H1-H2, then fill in H3 and lower-level subdivided content. At the same time, ensure that each level of title concisely summarizes the core of the paragraph, helping readers quickly locate the required information and improving the overall reading experience.
