Why H1-H6 Headings Matter

H1-H6 headings form the structure of an HTML document. Search engines use them to understand the topic and content hierarchy on a page. Proper heading structure helps Google better index and rank the page.

What This Tool Checks

  • H1 presence — the main page heading must be present
  • H1 count — there should be exactly one H1 per page
  • Hierarchy — headings should follow sequentially (H1 → H2 → H3), without skipping levels
  • First heading — H1 should be the first heading on the page
  • H2 subheadings — presence of subheadings for content structure
  • Overall structure — count of headings at each level

Heading Usage Rules

  • H1 — one per page, describes the main topic
  • H2 — page sections, subordinate to H1
  • H3-H6 — subsections within H2, H3, and so on
  • Don't skip levels: H2 should follow H1, not H3

Common Mistakes

  • Missing H1 — the search engine can't determine the main page topic
  • Multiple H1 tags — unclear which is the main one
  • Skipping levels (H1 → H3) — broken logical structure
  • Headings used only for styling — H tags should reflect content structure, not font size

Frequently Asked Questions

Can you use multiple H1 tags?
Technically HTML5 allows it, but for SEO one H1 per page is recommended. Multiple H1 tags confuse search engines — making it harder to determine the main topic.
Should H1 match the title?
Not necessarily. H1 and title are two different elements. Using different wording lets you cover more keywords. But they should be on the same topic.
Does heading order affect SEO?
Yes. Search engines use heading hierarchy to understand content structure. If H4 follows directly after H1, the search engine sees a logic violation, which can negatively affect rankings.
