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-Signal response header and its declared search/ai-train/ai-input values.
  • Also checks meta robots tags, the X-Robots-Tag header, and the canonical URL for the same page.
  • Flags disagreement between Content Signals and the domain's RSL declaration or robots.txt rules.

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.
