Heading Structure Analyzer
Check your page's heading hierarchy (H1-H6) for SEO best practices.
- • One H1 per page: Use a single H1 as your main title
- • Logical hierarchy: Don't skip levels (H1 → H3 without H2)
- • Descriptive text: Include keywords naturally in headings
- • Not just styling: Use headings for structure, not just visual formatting
- • Reasonable length: Keep headings concise but descriptive
About the Heading Structure Analyzer
Headings tell readers and search engines what a page is about at a glance. The Heading Structure Analyzer inspects the H1-H6 outline of any public URL so you can spot missing H1s, skipped levels, duplicate headings and other structural issues that quietly hurt SEO and accessibility.
What it does
Paste a URL and the tool fetches the rendered HTML, extracts every heading in the order they appear, and displays them as an indented outline. Warnings flag common problems such as multiple H1s, empty headings, or H4s appearing before an H3.
Why it matters
Search engines use heading hierarchy to understand the structure of your content. Screen readers use the same headings to help vision-impaired users navigate. A clean outline improves rankings, accessibility scores and user comprehension, all without touching the visible design.
How to use it
- Enter the full URL of the page you want to check.
- Click Analyze and let the tool crawl the page.
- Review the outline for exactly one H1 at the top.
- Look for warnings about skipped levels or empty headings.
- Rewrite headings so they describe the section beneath them clearly.
Best-practice tips
- Use exactly one H1 per page and make it match the search intent.
- Do not skip heading levels; H2 should follow H1, H3 should follow H2.
- Include target keywords in H2s where they read naturally.
- Keep headings under 70 characters so they are easy to scan.
- Never style regular text as a heading just to make it bold or larger.
Frequently asked questions
Can I have multiple H1 tags?
HTML5 technically allows multiple H1s inside separate sections, but for SEO clarity we recommend one H1 per page that clearly states the topic.
What is a good heading structure?
A single H1 followed by two to eight H2s that map to the main sections, with H3s used sparingly for sub-points. It should read like a clean table of contents.
Does heading structure really affect rankings?
Yes. Google uses headings to understand topical structure, and pages with a logical outline tend to perform better for their target queries.
