Frequently Asked Questions – Heading Structure Checker
Why is heading structure important for SEO?
Search engines use headings to understand page structure and content hierarchy. A proper H1 signals the main topic, while H2-H6 organize subtopics. Broken hierarchy confuses crawlers.
Should I have only one H1?
Best practice is one H1 per page. Multiple H1s are allowed in HTML5 but dilute the signal of your main topic.
