Free Heading Structure Checker
Analyze your page's heading hierarchy for proper nesting and structure. Fix heading issues that confuse screen reader users and hurt your SEO.
How Our Heading Structure Checker Works
Our heading checker maps out the complete heading hierarchy (H1 through H6) on your page and identifies structural problems. It detects missing H1 tags, multiple H1 tags, skipped heading levels (jumping from H2 to H4), empty headings, headings used purely for visual styling, and overly long headings that should be paragraphs instead.
The Impact of Heading Structure Checker Issues
Headings are the primary way screen reader users navigate web pages. Over 60% of screen reader users say they find information by navigating through headings. When headings are missing or improperly nested, blind users cannot scan your content or understand the page structure. Good heading hierarchy also improves SEO by helping search engines understand your content structure.
Issues Our Heading Structure Checker Finds
-
Missing H1 heading
Pages without a main H1 heading. Every page should have exactly one H1 that describes the page's primary content.
-
Skipped heading levels
Jumping from H2 to H4 or H1 to H3 without the intermediate level. This creates gaps in the document outline that confuse screen reader navigation.
-
Multiple H1 headings
More than one H1 on a page. While technically allowed in HTML5, best practice is a single H1 per page for clarity.
-
Empty headings
Heading elements with no text content, often left from template code. These appear as blank items in screen reader heading lists.

Frequently Asked Questions
Does heading structure affect SEO?
Yes. Search engines use heading structure to understand your page content and hierarchy. A clear H1 followed by logically nested H2-H6 headings helps search engines index your content properly. Google has confirmed that headings help them understand page structure.
Can I have more than one H1 on a page?
While HTML5 technically allows multiple H1 elements within sectioning elements, best practice for both accessibility and SEO is to use a single H1 per page. Multiple H1s can confuse screen reader users about the page's main topic.
What is the right heading order?
Start with a single H1 for the page title, then use H2 for major sections, H3 for subsections within H2s, and so on. Never skip levels - do not jump from H2 to H4. Think of headings as an outline of your page content.
