Frequently Asked Questions
Why is heading structure important for SEO?
A proper heading hierarchy (H1, H2, H3) helps search engines understand your content structure and improves readability. Missing H1s or skipped levels can harm rankings.
Should I have only one H1 per page?
Yes. Best practice is one H1 per page that describes the main topic. Multiple H1s can confuse search engines about the primary topic of the page.
What does 'skipped heading levels' mean?
Skipped levels occur when you go from H1 directly to H3 without an H2. This breaks the logical hierarchy and should be avoided for proper content structure.
