Paste HTML and review heading counts, skipped levels, empty headings and the visible outline.
This checker is for content QA after a CMS edit, template change or article migration. Paste rendered HTML and get a simple outline of the headings users and assistive technology encounter.
What it catches
The report flags missing or repeated first-level headings, skipped heading levels and empty headings. It also prints the detected outline so an editor can scan the page structure quickly.
Scope
The checker does not grade writing quality. It focuses on HTML heading structure in the pasted fragment.
