How do I check the heading structure of a page?

Enter the URL to extract and display the page's full H1–H6 heading outline.

Why do headings matter for SEO?

Headings create a clear content hierarchy that helps search engines understand page topics and helps readers scan content.

Should a page have only one H1?

Yes — one H1 per page is the safest practice; it defines the page's main topic for search engines and screen readers.

Can I skip heading levels?

Avoid skipping levels (e.g., H1 straight to H3); sequential headings keep the document outline logical for crawlers and assistive technology.

// HEADING STRUCTURE CHECKER · ABOUT THIS TOOL

About the Heading Structure Checker

This tool pulls every H1 through H6 from the page HTML, displays them as an indented outline, and flags missing or multiple H1s, skipped levels, empty headings and duplicate text.

Use it to QA articles before publishing or audit pages that underperform, and give both readers and crawlers a clean document structure.

Where it helps most

Wherever the outline shapes understanding.

Pre-publish QA

Content teams run it as a pre-publish QA step: paste the draft URL, fix every flag, then publish clean with confidence.

Underperforming pages

SEOs reach for it on underperforming pages, because a muddled outline usually means a muddled topic focus too for crawlers.

Landing pages

Templates inject extra H1s from logos and hero banners; audit your most important landing pages, not just blog posts first.

Template bugs

One audit pass across your top ten pages usually surfaces a template-level heading bug worth fixing everywhere at once today.

Checking well

Know what it catches, and its limits.

Classic faults

Flags missing or multiple H1s, skipped levels, empty headings and duplicate heading text.

Plain explanations

Each issue is explained in plain terms with the offending heading quoted.

Server HTML only

It reads server-rendered HTML, so headings injected later by JavaScript will not appear.

Heading Structure Checker: built for trust

Tightening the headings sharpens the page's message for crawlers and readers alike.
