FAQ
Why is heading structure important for SEO?
Search engines use headings to understand the content hierarchy and topic structure of a page. A clean heading hierarchy helps with indexing and can improve rankings for related queries.
How many H1 tags should a page have?
Best practice is exactly one H1 tag per page. It should contain the primary topic or keyword. Multiple H1s dilute topical focus.
What does "skipped heading level" mean?
Going from H2 directly to H4 (skipping H3) creates a gap in the document outline. While not a hard rule, maintaining proper nesting improves accessibility and SEO.
