Heading Structure Checker

Analyze the H1-H6 hierarchy of any page. Find missing, duplicate, or skipped headings that hurt SEO.

Heading Best Practices

  • Use exactly one H1 tag per page that describes the main topic.
  • Follow a logical hierarchy. Do not skip from H1 to H3 without an H2.
  • Keep H1 tags under 70 characters and include your primary keyword.
  • Use headings to structure content, not for styling. Use CSS for visual size.
  • Each heading should describe the section below it. Do not leave headings empty.
  • H2s are great for major sections, H3s for subsections within them.

Frequently Asked Questions

Why is heading structure important for SEO?

Search engines use heading tags (H1-H6) to understand the structure and topic hierarchy of your page. A clear heading structure helps Google understand what your content is about, which sections are most important, and how subtopics relate to the main topic. This directly impacts how your page ranks for relevant search queries.

Can I have multiple H1 tags on a page?

While HTML5 technically allows multiple H1 tags (one per section), SEO best practice is to use exactly one H1 per page. Multiple H1s can confuse search engines about the primary topic of your page and dilute keyword relevance. Use H2s for major sections instead.

What does "skipped heading level" mean?

A skipped heading level occurs when you jump from, say, H1 directly to H3 without using an H2 in between. This breaks the logical document outline and can confuse both search engines and screen readers. Always follow the hierarchy: H1 > H2 > H3 > H4, etc.

Do heading tags affect accessibility?

Yes, headings are critical for web accessibility. Screen readers use heading tags to navigate pages. users can jump between headings to find content quickly. Properly structured headings with descriptive text make your site usable for people with visual impairments and improve overall user experience.
