About this tool
Fetches a page, extracts every heading in document order and renders the outline, flagging missing H1s, multiple H1s and skipped levels. Good heading structure helps both screen readers and search engines understand the page.
How to use it
- Enter a public URL.
- Press Analyze headings.
- Fix skipped levels or missing H1s in your markup and re-check.
Frequently asked questions
How many H1s should a page have?
One is the clearest pattern for a single page topic. Multiple H1s are not automatically an error, but the outline should still make sense.
Why do skipped levels matter?
They break the document outline that assistive technology uses for navigation. Use CSS for visual size, not heading level.
