What does this audit check?
It scans a single public URL for 15+ on-page SEO signals: title tag, meta description, H1-H3 structure, word count, image alt text, internal/external link counts, Open Graph and Twitter card tags, canonical URL, structured data (JSON-LD), viewport meta tag, language attribute, favicon, HTTPS, and noindex status. Each signal produces a pass, info, warning, or critical issue. The score is computed from the severity weights.
How is the AI part different from the deterministic checks?
The deterministic checks are rule-based - they always return the same result for the same input. The AI layer reads all the signals together and writes a prioritized action list in plain English: 'this is your biggest risk, here is why, fix this first.' The AI never invents data - it only reasons about the signals already collected.
Can I audit private or staging URLs?
No. The auditor only works on public URLs. Private, loopback, and local hosts are blocked at the network level to prevent misuse. For staging audits, either deploy to a public preview URL first or use a dedicated on-site SEO plugin for private environments.
Is the score comparable to other audit tools?
Directionally, yes - the major signals are the same. But each SEO auditor weights issues differently, so a 70 here is not identical to a 70 in Ahrefs or Semrush. Use the score as a snapshot of your own progress (is it trending up?), not as a rank against competitors.
Why does it not check backlinks, traffic, or rankings?
Those require paid API data. Use the free Backlink Checker, Website Traffic Checker, and Keyword Rank Checker in this suite for those off-page signals. This tool focuses exclusively on what you can fix by editing your page directly.
Is this tool free?
Yes. The deterministic audit runs without consuming any quota. The AI summary uses 1 of your 5 daily AI generations (shared across all RankPill AI tools). If you hit the AI limit, the audit still returns - just without the AI narrative.
