Check a page's heading structureH1 to H6 outline
Check the outline readers and crawlers follow.
Headings are the skeleton of a page. A clean one makes content easier to scan, rank and quote.
Read the outline
See each heading and its level, indented by depth.
Fix the issues
Resolve missing H1s, skipped levels and duplicates.
One topic, one outline.
A good outline tells the whole story even if you only read the headings.
One H1 per page
The H1 names the page topic. Use H2 for main sections and H3 for detail beneath them.
Do not skip levels
Going from H2 straight to H4 breaks the outline for screen readers and makes structure harder to parse.
Write headings as answers or questions
Descriptive headings help readers scan and give AI assistants clean passages to quote.
