What Is the Heading Structure Checker?

Headings (H1-H6) outline a page for readers, screen readers and search engines. This tool lists a page's headings in order so you can see its structure.

When to Use It

  • When reviewing long articles or landing pages.
  • During accessibility and SEO audits.

How to Use It

  1. Enter the page URL.
  2. Review the heading outline.

Understanding the Result

Use one clear H1 for the page topic, H2s for main sections and H3s inside them. Avoid skipping levels just for styling, and do not use headings for non-heading text.

Limitations

Headings added later by JavaScript are not included.

Example of a Good Outline

H1  How to Speed Up a WordPress Site
  H2  Measure Your Current Speed
  H2  Optimise Images
    H3  Choose the Right Format
    H3  Lazy-Load Below-the-Fold Images
  H2  Enable Caching
  H2  Use a CDN

Anyone scanning the headings can see what the page covers and jump to the part they need.

Common Problems This Reveals

  • No H1, or the logo marked up as the H1 on every page.
  • Several H1s from a theme that styles widget titles as H1.
  • Skipped levels, such as H2 followed directly by H4, because a smaller font was wanted.
  • Headings used for layout - "Follow us" or "Newsletter" in the sidebar as H2s, cluttering the outline.
  • Vague headings such as "Introduction" or "More info" that say nothing about the content.

Why It Matters

Screen-reader users navigate by headings, so a clean outline makes a page usable for them. Search engines use headings to understand the topics on a page, and clear H2s sometimes appear as jump links in search results.

Also check the meta description and image alt text, and read how to write meta titles and descriptions.

Frequently Asked Questions

The H1 is conventionally treated as the primary topic statement for the page, both for accessibility (screen readers rely on it) and as a strong on-page relevance signal - multiple or missing H1s can dilute or confuse that signal.

Yes, this is a common and worth-fixing accessibility issue - screen reader users navigate by heading level, and skipped levels break the logical document outline, even if the visual styling looks fine to sighted users.

Naturally incorporating relevant keywords into headings is good practice, but headings should primarily and accurately describe the actual content beneath them - keyword-stuffing headings at the expense of clarity is a net negative.

Significantly, yes - a logical, correctly-nested heading structure is a core accessibility requirement, directly affecting how well screen reader and other assistive technology users can navigate and understand your content.

This is a common but discouraged practice - CSS can and should style any element regardless of its tag, so choosing heading levels purely for visual appearance (rather than actual content hierarchy) sacrifices both SEO and accessibility for no real benefit.
