How it works
Paste HTML, run the checker, and review whether the heading order is logical and whether common structure issues appear.
- Counts: shows how many H1-H6 tags exist
- Order: lists headings as they appear
- Issues: flags missing H1 or skipped levels
Examples
- Good structure: H1 → H2 → H3
- Skipped level: H1 → H3
- Possible issue: multiple H1 tags depending on page design choice

FAQ
- What does this heading structure checker analyze?
It analyzes pasted HTML for H1 through H6 headings, counts each level, lists them in order, and flags common structural issues such as missing H1 or skipped levels.
- Do I need to paste a full HTML page?
No. You can paste a full page, a content section, or only the HTML snippet you want to inspect.
- What is a skipped heading level?
A skipped level happens when the structure jumps, such as from H1 directly to H3, without an H2 in between.
- Does this tool judge content quality?
No. It checks heading structure only, not whether the heading wording is good.
- Is the pasted HTML stored?
No. Everything runs locally in your browser.
