Validation
Headings Checker
Analyze the H1-H6 structure of a page and detect basic problems of hierarchy, semantic clarity and document order.
INFO
WHAT DOES THE HEADING CHECKER CHECK?
This tool extracts H1, H2, H3, and other headings from the pasted HTML to show the actual structure of the document.
It helps detect missing H1s, multiple H1s, level jumps, and empty headings that make reading, crawling, and content segmentation more difficult.
-
Main H1:
Checks whether an identifiable H1 heading exists.
-
H1-H6 hierarchy:
Extracts heading levels and shows document structure.
-
Level jumps:
Detects jumps such as H2 to H4 without transition.
-
Empty headings:
Flags headings without meaningful text.
Questions about headings
Common questions about H1-H6, hierarchy, and structure.
Should a page have only one H1?
As a technical clarity guideline, yes. AISEO prioritizes a single, identifiable H1 to reduce ambiguity.
Are headings only for design?
No. They should describe the structure and hierarchy of the content, not be used only to change visual size.
Is skipping heading levels always bad?
It depends on the context, but inconsistent skipping makes structural reading and content segmentation more difficult.
