Heading Structure Analyzer
Extract and visualize H1-H6 heading hierarchy with SEO issue detection.
How to Use the Heading Structure Analyzer
Paste your HTML or Markdown content to extract and visualize the heading hierarchy (H1-H6). The tool shows a tree view of your headings and flags common SEO issues like multiple H1s or skipped heading levels.
Heading SEO Best Practices
- One H1 per page — Every page should have exactly one H1 that includes the primary keyword.
- Don't skip levels — Go from H2 to H3, not H2 to H4. Maintain logical hierarchy.
- Use headings for structure — Don't use headings purely for styling. They define document structure.
- Keep headings concise — Descriptive but short. Include relevant keywords naturally.
Frequently Asked Questions
Why is heading structure important for SEO?
Search engines use headings to understand your page structure and content hierarchy. Proper heading structure helps Google identify main topics and subtopics, improving relevance signals.
Can I have multiple H2 headings?
Yes. Having multiple H2 headings is normal and recommended. H2s represent main sections under your H1. The rule of "only one" applies to H1 only.
What does "skipped heading level" mean?
A skipped level means you jumped from, say, H2 to H4 without an H3 in between. This breaks the logical hierarchy and can confuse both search engines and screen readers.
Does this work with Markdown?
Yes. The tool recognizes both HTML headings (<h1> through <h6>) and Markdown headings (# through ######). You can paste either format.
