Heading tags
HTML elements (H1-H6) that define content hierarchy and structure.
What is Heading tags?
Heading tags (H1-H6) are HTML elements that define the hierarchical structure of content on a page. H1 is the main title, with H2 through H6 representing progressively smaller subsections.
Proper heading structure helps both users and search engines understand content organization. It improves accessibility for screen readers and helps search engines identify key topics.
Why Heading tags matters
Headings communicate content structure to search engines and help identify what a page is about. Well-structured headings improve user experience, accessibility, and can appear in featured snippets. They're an on-page SEO fundamental.
How to implement
Use one H1 per page for main topic
Structure H2-H6 in logical hierarchy
Include target keywords naturally in headings
Use headings to create scannable content
Don't skip heading levels (H1 to H3)
Don't use headings for visual styling only

Frequently asked questions
HTML5 technically allows multiple H1s with sectioning elements, but for SEO, stick to one H1 per page representing the main topic. Use H2+ for sections.
Depends on content length. Use as many as needed to create logical structure. Long guides might have 10+ H2s, each with H3 subsections.
