What is Heading Structure?

HTML headings (H1-H6) create a hierarchical structure for your content. This structure helps search engines understand content organization and improves accessibility for screen reader users.

This analyzer checks your heading hierarchy for common issues like missing H1 tags, skipped levels, and multiple H1s that can hurt SEO performance.

Heading Rules

One H1 per page: The H1 should be your main title.
Don't skip levels: Go H1 → H2 → H3, not H1 → H3.
Hierarchy matters: H2s under H1, H3s under H2.
Be descriptive: Headings should describe the content below.

Good vs Bad Examples

Good Structure

H1 → H2 → H3 → H3 → H2 → H3

Bad Structure

H2 → H4 → H1 → H3 (skips, wrong order)

FAQ

Can I use multiple H1s?

HTML5 allows it in theory, but SEO best practice is one H1 per page.

Should H1 match the title tag?

They can be similar but don't need to match exactly. Both should be relevant to content.
