Heading Hierarchy

Heading hierarchy provides structural clarity that benefits both search engines and users. The H1 tag identifies the page's primary topic and should be unique per page. H2 tags denote major sections, H3 tags mark subsections within H2 blocks, and so on. This creates a logical outline that search engines use to understand content organization and identify key topics.

For content and engineering teams, proper heading hierarchy improves SEO, accessibility, and user experience simultaneously. Use one H1 per page that includes the primary keyword. Structure H2 headings to cover main subtopics, which are often natural targets for featured snippets. Use H3 and below for supporting detail sections. Avoid skipping levels (jumping from H2 to H4) as this confuses the document outline. For dynamic content and component-based architectures, ensure that composed pages maintain a logical heading hierarchy even when sections come from different components. Audit heading structure as part of your content QA process and include heading hierarchy checks in your automated SEO testing suite.
