Paste HTML or fetch a URL to list headings and flag SEO issues such as missing H1 tags or skipped heading levels.
How to use this tool
1. Enter a page URL or paste HTML. 2. Run the checker to build the heading outline. 3. Review warnings about H1 count and level jumps. 4. Restructure headings for a logical, accessible hierarchy.
Worked example
Example: a page jumping from H1 to H3 triggers a warning — add an H2 section heading between them for better structure.
How it works
Parse H1–H6 tags from HTML and flag SEO issues such as missing H1, multiple H1s, or skipped heading levels in the document outline.
Limitations
Fetched pages may be blocked by browser security rules. Paste HTML for accurate heading outlines when live fetch fails.
