About this free heading outline checker

Heading hierarchy (H1–H4) structures content for users and crawlers. Multiple H1s or skipped levels confuse topical focus.

Count headings on a URL to spot template bugs and outline opportunities before a full content rewrite.

What it checks

  • Number of H1, H2, H3, H4 elements
  • Obvious structural red flags (zero H1, many H1s)

Why it matters for SEO

  • Clear outlines improve readability and featured snippet potential.
  • Supports accessibility for screen reader navigation.
  • Aligns on-page sections with target keyword clusters.

How to use this tool

  1. Audit blog posts and landing pages targeting competitive terms.
  2. Use one clear H1; break sections with descriptive H2s.
  3. Fix theme templates that output multiple H1s site-wide.

Common issues we help you catch

  • Logo and page title both wrapped in H1
  • Long pages with no H2 breaks
  • Empty heading tags for spacing (bad practice)

Frequently asked questions

Can I have more than one H1?
HTML5 allows multiple H1s, but one primary H1 per page is still best practice for clarity and SEO focus.
