Header Hierarchy
What is Header Hierarchy?
Header hierarchy organizes a page into nested sections. An H1 states the page topic; H2s and H3s break subtopics. It aids accessibility, skimming, and semantic parsing.
Example: A long guide uses one H1, H2s for major chapters (“Equipment,” “Training plan”), and H3s for steps—rather than bold text that looks like headings but is not marked up.
Why Header Hierarchy matters
Heading hierarchy matters for accessibility, skimming, and semantic structure; confusing headings make long pages unusable and obscure what section answers which query.
How Header Hierarchy works in digital marketing
Use one descriptive H1, keep levels in order, write headings as questions or outcomes where helpful, and mirror intent from your keyword map.
