About the Heading Structure Checker

Headings (H1 through H6) are the outline of a page. They tell readers — and search engines and screen readers — how the content is organized and what each section is about. A clean, logical heading hierarchy makes a page easier to scan, more accessible, and easier for search engines to understand.

This checker fetches any URL from our servers and maps the full H1–H6 outline, flagging the common problems: a missing or duplicate H1, and levels that skip (an H2 jumping straight to an H4).

How to use it

  1. Enter the full URL of the page you want to inspect, including https://.
  2. Press Check. We fetch the page and extract every heading in document order.
  3. Confirm there is exactly one H1 that states the page's main topic.
  4. Walk the outline for skipped levels or empty headings, then fix the structure so it reads as a clean nested hierarchy.

Why it matters for SEO

  • A single, descriptive H1 gives search engines a strong signal about the page's primary topic — pages with no H1 (a common Chakra/React mistake) leave that on the table.
  • A logical heading order is an accessibility requirement: screen-reader users navigate by heading level, and skipped levels make that confusing.
  • Well-structured headings map naturally to the questions people search, improving your odds of winning featured snippets and passage-level ranking.
  • Clear section headings keep readers on the page longer, which supports the engagement signals that influence rankings.

Frequently asked questions

How many H1 tags should a page have?

Exactly one. The H1 should state the page's main topic. Multiple H1s or none at all muddy the signal about what the page is primarily about.

Is it bad to skip heading levels?

Yes. Jumping from an H2 straight to an H4 breaks the outline for assistive technology and weakens the structural signal for search engines. Keep the nesting sequential.

Do headings affect SEO?

Indirectly but meaningfully. Headings clarify topic and structure, improve accessibility and readability, and often become the text that wins featured snippets — all of which support ranking.

Is the heading structure checker free?

Yes — it is completely free with no sign-up. It fetches the public HTML of any URL and maps its heading outline.
