Heading Outline Checker
Score whether the page starts with one h1, uses h2 sections, and never skips from h1 to h3 — not a ranking trick.
What this tool gives you
Check heading outline
Fetch a public page or paste HTML. The checker scores h1 → h2 → h3 order — not a ranking trick.
What this checker looks for
One h1 names the page. h2 sections answer questions. h3 is a nested detail, not a skipped jump.
Starts with h1
The first heading in the document should be the page topic.
One h1
HTML5 allows extras. Snippets still prefer one topic heading.
No skipped levels
Do not jump from h1 to h3. Nest one level at a time.
h2 sections
A lone h1 is a title, not an outline. Add section headings.
Visible text
Empty or hidden headings still get announced to screen readers.
Not a ranking lever
This is outline hygiene, not a citation trick.
How to use the checker
Fix the unique h1 first, then the outline, then image alt.
Check the live page
Fetch the public URL or paste the HTML from view-source.
Start with one h1
Name the page topic, then add h2 sections for each answer block.
Do not skip levels
h3 belongs under an h2. Never jump from the page h1 to h3.
What a healthy outline usually includes
One h1. Two or more h2 sections. h3 only when a section needs nested detail. No empty headings.
| Part | Job | Default for public sites |
|---|---|---|
| h1 | Page topic | Exactly one, first heading in the document |
| h2 | Section / question | One per answer block under the h1 |
| h3 | Nested detail | Only under the matching h2 |
| Skip | h1 then h3 | Never. Insert the missing h2 |
| Empty | Hidden or blank tags | Delete them or put visible words in |
| Never | h1 stuffing | Do not repeat the title keyword in every heading |

Heading outline FAQs
Does a perfect heading outline make ChatGPT cite my page?
No. Outlines help humans and crawlers scan the page. Citations still depend on crawl access, answer-ready content and corroboration.
Is skipping from h1 to h3 a ranking penalty?
No. It is an accessibility and scanability problem. Screen readers and table-of-contents extractors expect one step at a time.
Do I need h3 on every page?
No. h2 sections are enough for most marketing pages. Use h3 only when a section has nested details.
