Enter a URL or paste your HTML to get a visual H1–H6 outline plus instant checks for missing or duplicate H1s, skipped levels and empty headings.
We fetch the page server-side and analyze its HTML headings.
Paste full page source or just the body markup, or fetch any public URL.
The H1 states the page's main topic. Multiple H1s or a missing one muddies what the page is about.
Headings should nest like an outline: H2 under H1, H3 under H2. Skipping from H2 to H4 breaks the hierarchy.
Well-structured headings give Google and AI clear sections to pull answers and snippets from.
