Heading structure checker: review H1–H6 outline and full headings

A clean heading hierarchy helps users scan a page and helps crawlers understand sections. This tool shows a list view (counts per URL) and a detailed view (overview + full headings).

What this tool detects

  • H1 problems: missing H1 or multiple H1.
  • Skipped levels: jumps like H2 → H4.
  • Full headings list: all heading texts grouped by level.

Best practice

  • Use one main H1, then build sections with H2 and subsections with H3/H4.
  • Keep headings descriptive and consistent across templates.

FAQ

Why is the UI split into 3 tables?

Because it’s readable. The list table stays compact (counts per URL), while the selected URL shows two separate tables: Overview and Full Headings.

What does “skipped levels” mean?

It means heading jumps like H2→H4 or H3→H5. Technically it renders, but it usually signals messy templates and a confusing outline for users and assistive tech.

Is missing H1 always a problem?

Not always, but usually yes. A single clear H1 helps define the page topic. Some designs fake headings using div/span, which makes structure worse for accessibility.

Is multiple H1 always bad?

Multiple H1 can be valid in HTML5 in some patterns, but in real SEO/content workflows it usually indicates duplicated templates (logo/title repeated) or poor content hierarchy.

Why can the tool show “no headings found” even if the page has headings?

Because the checker reads server HTML only. If headings are injected by JavaScript after load, the raw HTML may not contain them. Also, some sites use styled text instead of actual H1–H6 tags.

Why does the tool limit headings per level?

For performance and safety. Pages can contain thousands of headings (spam, infinite lists, or broken markup). Counts remain accurate, but the “Full Headings” list is capped per level.

Does fixing headings guarantee better rankings?

No guarantees. But good heading hierarchy improves readability, crawl understanding, and accessibility — that’s “on-page quality” and it rarely hurts.

What’s a “good” heading structure?

A common clean pattern is: one main H1, then section H2, and nested subsections with H3/H4 — without random jumps.
