Why does skipping a heading level (like H2 straight to H4) matter?

It breaks the logical outline both search engines and screen reader users rely on to understand your content's structure and hierarchy.

Should a page ever have more than one H1?

Generally no — a single H1 representing the page's main topic is the standard recommendation, with H2-H6 used for the structure beneath it.

Does heading structure actually affect search rankings?

It's one of many signals search engines use to understand content structure — its direct ranking impact is modest, but it meaningfully helps both crawlers and accessibility tools parse your content correctly.

Does Heading Structure Analyzer upload my files to a server?

No. Heading Structure Analyzer runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

A page's heading structure (H1 through H6) should follow a logical hierarchy — skipping levels or having multiple H1s confuses both search engines trying to understand your content's structure and assistive technology users navigating by headings. This tool scans pasted HTML and shows your heading outline, flagging missing or skipped levels, surfacing structural problems that aren't obvious just from how the page visually renders.
