Why heading structure matters
Headings are the skeleton of a page. They break content into readable sections and tell search engines and screen readers what each block is about.
This checker reads the headings in your HTML and draws the outline, so you can see at a glance whether the levels flow in order.
How to check your headings
- Paste the page HTML, or fetch a live page.
- Press check to count every heading level.
- Review the counts for H1 through H6.
- Read the outline to see the visual hierarchy.
- Fix skipped levels and re-check until it is clean.
Signs of a healthy structure
- Exactly one H1 on the page.
- H2 headings divide the main sections.
- H3 headings sit under H2 without jumping levels.
- No empty headings that give readers nothing to see.
A common mistake
Skipping from H1 straight to H3, or using H2 purely for styling, breaks the outline. If a heading is just visual, use a styled paragraph instead and keep the real structure tidy.
