What this means in practice
Headings create a document outline for people, assistive technology, and machines. A strong hierarchy makes long pages easier to scan and understand.
Implementation path
- Use one clear page-level heading that names the primary topic.
- Use h2 and h3 elements according to document structure, not because a visual size looks attractive.
- Make headings informative enough that a reader can skim them and understand the page.
- Avoid inserting keywords into every heading when a natural phrase is clearer.
What good looks like
A strong implementation makes the intended behavior obvious to a visitor, a crawler, and a machine reader. It has one clear purpose, uses consistent signals, and does not rely on hidden assumptions.
