How to Check Heading Structure
Headings (H1–H6) play a critical role in both SEO and accessibility. However, when writing content in a CMS or rich text editor, it's easy to accidentally skip heading levels or end up with multiple H1 tags. This guide shows you how to use Heading Structure Checker to quickly audit and fix heading hierarchy issues.
Why Heading Structure Matters
SEO Impact
- Search engines use heading structure to understand the content hierarchy of a page
- H1 represents the main topic and should generally appear only once per page
- Proper heading structure can influence how your page appears in search results (rich snippets, etc.)
Accessibility Impact
- Screen readers use headings to navigate through page content
- Skipping from H2 to H4 (missing H3) can confuse and disorient users
Common Heading Issues
| Issue | Example | Impact |
|---|---|---|
| Missing H1 | Page has no H1 tag | Main topic is unclear |
| Multiple H1s | Two or more H1 tags | Dilutes the main topic |
| Skipped levels | H2 → H4 (skipping H3) | Broken hierarchy |
| Empty headings | H tag with no text | Meaningless heading |
How to Use It
Step 1: Install
Install "Heading Structure Checker" from the Chrome Web Store.
Step 2: Open the page you want to check
Navigate to any page where you want to audit the heading structure — your own site before publishing, a competitor's page for analysis, or any content you're reviewing.
Step 3: Detect headings
Click the extension icon in your toolbar and press the "Detect Headings" button. All headings will be displayed in an indented list, with warning badges highlighting any issues.
Step 4: Review and act on results
- Check warnings: Review and fix any flagged issues — skipped levels, duplicate H1s, or empty headings
- Copy as text: Use the "Copy Text" button to export the structured heading outline. Paste it into reports or share with your team for corrections.
- Count summary: See how many headings exist at each level (H1–H6) at a glance
Best Practices
- Use exactly one H1 per page
- Follow heading levels in order (H2 → H3 → H4)
- Don't use heading tags purely for visual styling
- Make sure every heading contains meaningful text
- Include a heading check in your pre-publish routine
