Definition
Heading structure refers to the hierarchy of HTML heading tags from H1 (main title) to H6 (level 6 subtitle). This structure organizes content logically, helping search engines understand the content architecture and users navigate it. H1 is the main title (one per page), H2s are main sections, H3s are subsections, and so on. A good heading structure improves readability, accessibility, and SEO.
