Content Signals checker
Enter a domain to detect a recognised Content-Signal response header, plus its meta robots tag, X-Robots-Tag header, and canonical URL — and flag any disagreement against its RSL declaration or robots.txt rules.
What this checks
- Detects a
Content-Signalresponse header and its declaredsearch/ai-train/ai-inputvalues. - Also checks meta robots tags, the
X-Robots-Tagheader, and the canonical URL for the same page. - Flags disagreement between Content Signals and the domain's RSL declaration or
robots.txtrules.
What this does not check
Content Signals is a proposal (published by Cloudflare, September 2025) — not a ratified standard, and no major crawler is currently known to honour it in practice. A separate, more formal IETF effort (AI Preferences) is still in draft. See limitations.
