Heading Structure Analyzer

Visualize H1-H6 hierarchy and detect structural or accessibility issues.

What is the Heading Structure Analyzer?

Headings (H1-H6) give Google a clear outline of your content. A well-structured heading hierarchy helps search engines understand your page topics and improves accessibility for screen readers. This tool visualizes your heading tree and flags common issues like missing H1s, skipped levels, or duplicate headings.

How to Use

  1. Enter the URL you want to analyze
  2. The tool extracts all headings (H1 through H6) from the page
  3. Review the visual hierarchy — headings should follow a logical order
  4. Fix any flagged issues: missing H1, skipped levels, or duplicates

Why This Matters for SEO

Google uses heading tags to understand page structure and topic hierarchy. A page with a clear H1 followed by organized H2-H3 subheadings ranks better for related queries. Multiple H1 tags or skipped heading levels (H1 → H3 with no H2) signal poor content organization.

Tips & Best Practices

  • Every page should have exactly one H1 tag containing the primary keyword
  • Use H2s for main sections and H3s for subsections — never skip levels
  • Keep headings descriptive — "Our Services" is better than "Section 2"
  • Front-load keywords in headings when it reads naturally
  • Heading structure should make sense if you read only the headings

Frequently Asked Questions

How many H1 tags should a page have?
Every page should have exactly one H1 tag. While HTML5 technically allows multiple H1s, a single H1 is the SEO best practice because it clearly signals the main topic to search engines.
What is heading hierarchy?
Heading hierarchy is the logical order of headings from H1 (most important) through H6 (least). A proper hierarchy means an H3 always appears under an H2, never directly under an H1 with no H2 in between.
Do headings affect SEO rankings?
Yes. Google uses headings to understand page structure and topic relevance. Pages with clear heading hierarchies rank better because Google can identify the main topic and subtopics more accurately.
