Frequently asked questions
Why do headings matter for SEO?
Headings show the structure and topics of a page. Search engines use them to understand sections, and screen-reader users jump between them, so a clear outline helps both.
Is it bad to skip heading levels?
It's not a ranking penalty, but jumping from H2 to H4 breaks the outline for screen readers and accessibility checks. Go one level down at a time.
Should headings include my keyword?
Use your main topic in the H1 and related phrases in some H2s where they fit naturally. Write headings for readers first: clear headings also help AI answers quote your page.
