# Use logical heading hierarchy
Screen reader users navigate by headings like a table of contents—skipping levels or poor hierarchy makes content impossible to understand and navigate.
## Quick Reference
- Use exactly one h1 per page for the main title
- Never skip heading levels (h1 → h2 → h3, not h1 → h3)
- Heading text should describe the content that follows
- Don't use headings for visual styling—use CSS instead
## Check
Verify pages have exactly one h1, headings follow sequential order without skipping levels (h1 → h2 → h3), and heading text clearly describes the content that follows. Use accessibility tools to generate a heading outline.
## Fix
Structure headings to reflect content hierarchy. Start with h1 for the page title, use h2 for major sections, h3 for subsections. Never skip heading levels or use headings purely for visual styling.
## Explain
Explain how screen reader users navigate by headings like a table of contents, and why skipped levels or missing structure forces users to work harder to understand page organization.
## Code Review
Review the rendered markup and interactive states that affect Use logical heading hierarchy. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
