Got questions about heading audits?
Yes, heading hierarchy helps Google understand the relative importance of sections. Skipping levels (e.g., H2→H4) can confuse crawlers, reducing content clarity and ranking potential.
HTML5 allows multiple H1s if sectioned properly, but it's risky. Most SEO tools flag duplicate H1s as a potential issue. Our checker highlights them so you decide best practice.
Absolutely. Core heading analysis will always be free — no hidden limits, no trial expiration. SEOScaleUp's mission is to democratize technical SEO tools.
Yes, our crawler executes JavaScript to render the DOM, so we extract headings even from client-rendered SPAs. You'll see exactly what Google sees.
For dynamic sites, run a check after every major content update. For blogs or ecommerce, we recommend monthly audits to catch new structural issues.
Skipping occurs when you jump from H2 to H4 without using H3. This breaks semantic structure, making it harder for assistive tech and search engines.
Currently our tool analyzes public URLs only. For staging sites, you may need to temporarily disable authentication or use a public preview link.
We're building heading checker API access for agencies. Join the waitlist inside the dashboard to get early beta access soon.
