H1/H2 Heading Analyzer
Paste a page's HTML to see its full heading outline and catch structural issues before they affect how search engines and screen readers understand the page.
Outline
- H1: Page Title
- H2: First Section
- H3: A Subsection
- H2: Second Section
Issues
No issues found.
Analysis happens entirely in your browser — the HTML you paste is never uploaded anywhere.
Processing happens locally in your browser. Nothing you enter is uploaded.
How It Works
Paste the page's HTML (view-source, or just the relevant section) to see the heading outline and any issues.
Example
A page with <h1>Title</h1> followed directly by <h3>Detail</h3> (skipping h2) is flagged as a skipped heading level.
Frequently Asked Questions
- Why does heading structure matter?
- Search engines and assistive technology (screen readers) use headings to understand a page's structure — a missing H1 or skipped levels make that harder.
- Does this fetch my page for me?
- No — paste the HTML directly. Nothing is uploaded or fetched from a URL.
