Heading Hierarchy
Pro Tip: Your page should have exactly one H1 tag that describes the main topic. Then use H2 tags for major sections and H3-H6 for subsections. Never skip heading levels - if you have an H2, the next heading should be H2 or H3, not H4.

Why Does Heading Structure Matter for SEO?

Search engines use your heading tags to understand what your page is about. They look at your H1 to figure out the main topic, and then they scan your H2s and H3s to understand the subtopics you cover. If your heading structure is a mess, Google has a harder time figuring out what your content is actually about.

Good heading structure also helps users scan your content quickly. Most people don't read web pages word for word - they skim the headings first to decide if the content is worth reading. Clear, descriptive headings make your content more accessible and keep people on your page longer.

What is the Correct Heading Hierarchy?

The correct heading hierarchy follows a logical outline structure, similar to how you'd organize a book or a research paper. Here's how it should work:

  • H1 is your main title - you should only have one per page.
  • H2 tags are for major sections that break up your content.
  • H3 tags go under H2s for subsections within those major sections.
  • H4, H5, and H6 follow the same pattern for deeper nesting.

The key rule is to never skip levels. If you have an H2, the next heading should be either another H2 (for a new section at the same level) or an H3 (for a subsection). Jumping from H2 to H4 breaks the logical structure and confuses both search engines and screen readers.

Common Heading Mistakes to Avoid

A lot of websites make the same heading mistakes over and over. Here are the most common ones this tool will catch:

  • Multiple H1 tags on a single page confuse search engines about your main topic.
  • Missing H1 tags mean Google has to guess what your page is about.
  • Skipping heading levels (like going from H2 to H4) breaks the logical structure.
  • Using headings just for styling instead of structure is a common problem.
  • Empty heading tags that contain no text waste valuable SEO real estate.
  • Headings that are too long lose their impact and can get truncated.

This tool checks for all of these issues and gives you specific recommendations on how to fix them.

How to Use This Tool

This tool gives you two ways to analyze your content:

  • Paste HTML directly if you have access to your page's source code. The tool will extract all heading tags automatically.
  • Paste plain text if you're working on a draft. Use markdown-style headings (# for H1, ## for H2, etc.) or just put your headings on their own lines.

After you click Analyze, you'll get a score from 0-100 based on how well your headings follow SEO best practices. You'll also see a visual tree of your heading hierarchy and a list of specific issues to fix. The goal is to get as close to 100 as possible.
