H1-H6 headings form the hierarchical structure of a page. Proper structure helps search engines understand the content and users navigate through it.
| Level | Purpose | Count |
|---|---|---|
| H1 | Main page heading | One per page |
| H2 | Main sections | Multiple |
| H3 | Subsections within H2 | As needed |
| H4-H6 | Deep nesting | Rarely |
**One H1 per page** — contains the main topic
**Don't skip levels** — H3 follows H2, not H4
**Logical nesting** — H3 expands on the H2 topic
**Meaningful headings** — describe the section content
