On-Page SEO
Heading structure
Heading structure is the ordered set of semantic headings that labels and organizes the sections of a web document.
What it means
HTML headings from H1 through H6 identify section topics and provide navigation landmarks for assistive technology. A useful structure follows the content's logical relationships rather than the visual size desired by a designer.
Why it matters
Descriptive headings help readers scan, navigate and understand long documents. They also give systems clearer section boundaries, but their primary value is organization and accessibility rather than Keyword placement.
Example
A guide uses one main H1, H2 headings for Eligibility, Documents and Submission, and H3 headings for exceptions within each section. CSS controls appearance without changing semantic ranks.
Common mistakes
Do not use headings only to enlarge text, skip levels to obtain a style or convert every bold label into a heading. Avoid judging structure solely by counting H1 elements without reading section relationships.

Problem AYSA can identify
AYSA can identify unlabeled sections, style-only headings and rank sequences that obscure the document organization.
