Heading Tag Checker
Short answer
Verify heading hierarchy (H1-H6) for proper structure and SEO.
What It Does
Lists your page's headings in order and checks three things: exactly one H1, no skipped levels (such as an H2 followed by an H4) and no empty headings. Returns a score, the heading outline and the checks that failed.
Why It Matters
Headings do two jobs. Screen reader users jump between them to find their way around a page, and search engines read them to understand how the content is organized. A missing H1, empty headings or jumps between levels make both harder.
How It Works
-
Enter a page URL or paste its HTML
-
We fetch the live HTML and extract every H1–H6 in document order
-
Validate H1 count, heading order, and empty headings
-
Return a score, the heading outline and the checks that failed
Sample input + output

Frequently Asked Questions
Should every page have exactly one H1?
HTML allows more than one, and Google has said multiple H1s are not a problem for search. One H1 that names the page topic is still the clearest choice for readers and screen reader users, and it is what this check expects.
Can I skip heading levels?
Avoid it. A jump from H2 to H4 suggests a missing section to screen reader users, and the W3C's accessibility tutorials recommend nesting headings in order.
Does H1 need the primary keyword?
An H1 that says plainly what the page is about helps readers and search engines, and it usually contains the main topic. Write it for people first.
What length is ideal for headings?
There is no fixed limit. Keep headings short and easy to scan; a very long heading usually means the section should be split. This tool does not measure heading length.
Does it check ARIA landmarks?
No — this tool checks heading order and presence only. ARIA landmark roles (main, nav, aside) are a separate check this tool doesn't perform.
