Heading structure FAQ
Why does heading hierarchy matter for SEO?+
Search engines use headings to understand page structure and topic relevance. A clear H1 to H6 hierarchy helps Google parse your content correctly. Skipped levels (H1 jumping to H3) confuse crawlers.
How many H1 tags should a page have?+
Exactly one. Your H1 is the primary topic signal for that page. Multiple H1s dilute the signal and make it harder for search engines to determine the main topic.
What happens if I skip heading levels?+
Going from H2 directly to H4 (skipping H3) breaks the logical outline. Screen readers and search engines both rely on sequential heading levels to understand content relationships.
Does this tool check competitor pages?+
Yes. Paste any public URL. Checking how competitors structure their headings helps you find gaps in their content organisation that you can exploit.
