Free SEO tools / Heading Structure Checker
Enter a page URL and the tool prints its heading outline from H1 to H6 and flags the usual problems: no H1 or more than one, levels that skip (H2 straight to H4), empty headings, repeated headings and headings that read like paragraphs. Each problem comes with the fix.
Free, no sign-up, no email needed.
HTML allows it. One H1 that names the page's topic is the clearest structure for readers, screen readers and parsers, so the checker flags more than one as a warning, not an error.
Screen-reader users navigate by heading level and a jump from H2 to H4 reads as a missing section. Nested levels also make the outline easier for any parser to split into sections.
Headings help people and parsers understand the page structure. This tool does not claim a ranking effect.
A heading tag with no text, often left behind by a template or used for spacing. Screen readers announce it as an empty heading.
It reads the HTML the server sends. Headings that a script adds after the page loads are not in it.
