Heading Hierarchy

The structured use of H1-H6 tags to organise page content for users and crawlers.

A clean heading hierarchy uses one H1 for the main topic, H2s for major sections, H3s for subsections and so on. Skipping levels (H1 to H4) confuses crawlers and assistive technology. Logical hierarchy improves accessibility, readability and the chances of winning featured snippets. Wix's heading checker tool surfaces hierarchy issues across an entire site in seconds.
