The logical nesting of headings (H1 to H6) that organises a page into a clear, scannable structure.
Heading hierarchy is the ordered use of H1 through H6 tags to break content into a meaningful outline, with subheadings nested logically under their parent sections. A clean hierarchy helps search engines understand a page's structure and topic coverage, improves accessibility, and makes passages easy for AI systems to extract and cite. Skipping levels or using headings purely for visual styling weakens this signal, so structure should reflect meaning, not appearance.
