Things people ask
- What does CrawlRanker actually do?
- Two scores from one URL. SEO side: title tags, headings, mobile readiness, schema, broken links, alt text. The stuff a careful human reviewer checks. AI side: how much of the page reads machine-made across content, structure, imagery, and tone. Confidence percentage on every finding.
- Is my scan public?
- Yes. Submitting a URL creates a public report at crawlranker.com/.../s/[id] that anyone with the link can view, and it appears in our sitemap. That's the core mechanic. Public reports are how the methodology gets challenged and how good scans build trust. If you don't want a particular scan published, don't submit it. Removal requests work. See the Terms page.
- Do I need an account?
- No. The free scanner doesn't require sign-up, payment information, or any personal details. You paste a URL, you get a result. Accounts arrive in a later release for users who want a private scan history. The free public scan stays free.
- How long does a scan take?
- First result in under 30 seconds for most sites. The scan fetches the page once, parses it server-side, runs the SEO rubric, then asks Claude to read the same content for the AI-automation score. Slow or large sites take longer. Sites blocking our crawler return a clear error rather than a guess.
- How accurate is the AI-automation score?
- Useful where the signal is strong, honest about where it isn't. Every score includes a confidence percentage. Pages with mixed signals deliberately produce lower confidence and a 'Mixed signals' verdict rather than a forced call. When confidence drops below 0.6 the scan automatically re-runs on a stronger model. The full methodology is published. See the link in the navigation.
- Is this a plagiarism detector?
- No. The score is a fingerprint of the page itself. It doesn't compare against any other page or corpus, and it doesn't produce a 'copied from' output. A page can be entirely original and still score high on AI-automation if a person used a model to draft the prose. The score reads automation, not originality and not quality.
