Heading Structure Checker
Heading tags (H1–H6) are one of the most important on-page SEO signals. They tell Google the structure and topics of your page. A correct heading hierarchy improves rankings and accessibility.
What does the Heading Structure Checker check?
Everything you need to know about your heading structure checker in one report.
H1 Tag Validation
Checks that exactly one H1 tag exists on the page (not zero, not multiple).
Heading Hierarchy
Validates that headings flow in logical order (H1 → H2 → H3) with no skipped levels.
Heading Count
Lists all headings by level and flags pages with too few or too many headings.
Duplicate Headings
Identifies identical heading text that appears multiple times on the same page.
Empty Headings
Finds heading tags with no text content — invisible to users but confusing for crawlers.
Heading Length
Flags headings that are too long or too short to be effective SEO signals.

Frequently asked questions
How many H1 tags should a page have?
Exactly one. The H1 is your page's main title — it should contain your primary keyword and clearly describe what the page is about. Multiple H1s confuse both users and search engines.
Do heading tags directly affect SEO rankings?
Yes. Google uses headings to understand page structure and topic relevance. Your H1 and H2 headings should include your target keywords naturally — not stuffed, but genuinely descriptive.
What is heading hierarchy and why does it matter?
Heading hierarchy means H2s are subsections of H1, H3s are subsections of H2, and so on. Skipping levels (H1 → H3) breaks the structure, making it harder for Google to understand the page and hurting accessibility.
Should my H1 match my page title (meta title)?
They should be similar but don't need to be identical. Your meta title appears in search results; your H1 is the visible headline on the page. Both should include your primary keyword.
