Analyze your HTML heading structure (H1-H6) for SEO best practices. Check for proper hierarchy, missing headings, and common structural issues.
Proper heading structure is crucial for both SEO and accessibility. Search engines use headings to understand content hierarchy and topic relevance. Screen readers use them for navigation. A well-structured page has exactly one H1, followed by properly nested H2-H6 levels without skipping.
Good Structure = 1 H1 + Multiple H2s + Nested H3-H6 under H2s + No skipped levelsThe ideal heading structure: one H1 (main topic), H2s for major sections, H3s for sub-sections under H2s, and so on. Never skip levels (e.g., H1 → H3 without H2). Think of it as a table of contents for your page.
| Input | Output |
|---|---|
| <h1>Title</h1><h2>Section 1</h2><h3>Subsection 1.1</h3><h2>Section 2</h2> | ✓ Good structure: 1 H1, 2 H2s, 1 H3 — Proper hierarchy maintained |
| <h1>Title</h1><h3>Skip to H3</h3> | ✗ Issue: Skipped H2 level — H3 found without parent H2 |
| <h1>Title 1</h1><h1>Title 2</h1> | ✗ Issue: Multiple H1 tags found — Use only one H1 per page |
