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
- Enter the URL you want to analyze
- The tool extracts all headings (H1 through H6) from the page
- Review the visual hierarchy — headings should follow a logical order
- 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.

When This Tool Pays Off
Single-purpose tools like this one are most valuable in three moments of a typical SEO workflow. The first is right after you publish or update a page — running a quick check catches small mistakes (a missing tag, an oversized snippet, a forgotten redirect) before Google sees them. The second is during a focused audit, when you're working through a list of pages and need a fast, consistent diagnostic. The third is during competitive research: running the same tool against competing pages tells you where the gaps are.
Free tools like this one are deliberately narrow. They answer one question fast, with no signup or daily limit. That makes them great for spot checks but tedious as a long-term workflow. If you find yourself running the same set of tools every week against the same domain, that's the moment the full PageSEO weekly plan saves you time — same data, prioritized, on a schedule, with the actual action you should take next instead of a stack of metrics.
Privacy & Limits
Every tool on this site runs against public URLs. We don't store the URL you submit beyond the request itself, and there are no accounts, no email signups, and no daily quotas. The tools are rate limited per IP to keep the service available for everyone, but casual use never hits the limits. If a tool fails on a specific URL, the most common reason is the page is behind authentication or blocking automated crawlers via robots.txt — try the URL in an incognito window to confirm it's actually publicly reachable.
