SEO issues
  • No H1 found — every page should have exactly one H1.

What this tool does

Heading hierarchy (H1-H6) structures your page for screen readers and search engines. One H1 per page, logical nesting, and descriptive heading text improve SEO and accessibility.

How to use it

  1. 1

    Paste your page HTML source (View Source in browser).

  2. 2

    Review all headings in order with their levels.

  3. 3

    Fix issues like missing H1 or skipped heading levels.

Fixing structure issues

Multiple H1s often come from CMS themes — demote extras to H2. Skipped levels (H2 to H4) confuse parsers — insert the missing level or reassign.

Headings should describe the section below, not serve as styling shortcuts.

Tips

  • Include keywords in H1 and one H2 naturally.
  • View page source or use this tool after publishing to audit live HTML.
