Book a Free CallThink of headings as the outline of a document. Each page should have one H1 that states the main topic, then H2s for the main sections, and H3 to H6 nested underneath them in order. A clean hierarchy helps search engines understand your content and lets screen-reader users navigate the page quickly.
The usual culprits are more than one H1 on a page, skipping a level (jumping from H2 straight to H4), empty headings used only for styling, and headings made from an image without alt text. This tool flags each of these so you can fix the outline before it costs you clarity or rankings.
One. The H1 is the page's main title; use H2 to H6 for the sections and subsections beneath it.
They can be similar but don't have to be identical. The title tag is for search results; the H1 is the headline on the page.
It's best to lead with the H1. An H2 above it usually points to a template or layout issue worth fixing.
Yes. Screen-reader users navigate by headings, so a logical H1 to H2 to H3 order makes your page much easier to use.
Jumping from, say, an H2 straight to an H4 with no H3 in between. It breaks the outline for both readers and assistive tech.
Keep it concise and descriptive, ideally under about 70 characters, with your main topic near the front.
Use them naturally where they fit, but write for clarity first. Forced keywords in headings help no one.
