Heading outline
Why heading structure matters
Headings create a logical outline of your content. A single clear H1, well-ordered H2/H3 sections and descriptive wording help users scan the page and help search engines understand topical hierarchy and key entities.
One H1
Use a single H1 that matches the primary topic of the page.
Logical order
Do not skip levels (H2 → H4). Nest sections properly.
Descriptive text
Headings should summarize the section, not just list keywords.
How to use this tool
- Copy the HTML of the main content area (or full page source).
- Paste it into the box and click Analyze Headings.
- Review the outline, fix missing H1s, skipped levels or vague wording.
- Copy or download the report for documentation or client delivery.
Best practices
- Mirror the H1 in the title tag when natural.
- Use H2s for major sections and H3s for subsections.
- Keep headings unique within the page.
- Avoid using headings purely for visual styling—use CSS instead.
Frequently asked questions
Can I have multiple H1s?
HTML5 allows it in some contexts, but for SEO clarity one primary H1 per page is still the safest recommendation.
Do headings affect rankings directly?
They help relevance and usability. Clear structure supports topical understanding and featured-snippet eligibility.
