Heading Checker
List H1, H2 and H3 headings on a page and spot missing or duplicate structure issues.
What this tool checks
This tool extracts all H1, H2 and H3 headings from a page and lists them in order. It counts H1 tags and flags pages with missing or multiple H1 elements.
Why it matters
Headings give both users and search engines a hierarchical outline of your content. A page without an H1 loses a key relevance signal. Multiple H1 tags can confuse crawlers about the main topic.
How to fix common issues
Ensure every page has exactly one H1 that describes the primary topic. Use H2 for major sections and H3 for subsections. Avoid skipping levels (e.g. going from H1 directly to H4). Keep headings concise and descriptive.
Frequently asked questions
- How many H1 tags should a page have?
