Free Canonical URL Checker

Paste a URL. We'll fetch it, follow redirects, parse the head, and tell you the canonical URL, robots meta, redirect chain, title, description, and hreflang annotations — plus flag common SEO issues.

What this checks

  • Canonical tag — present? Self-referencing? Or pointing elsewhere?
  • Redirect chain — every hop between your input URL and the final destination. Multi-hop chains bleed link equity.
  • Robots meta — is the page accidentally noindexed?
  • Title + description — present? Within optimal length (60 / 160 chars)?
  • Hreflang — international-SEO annotations for multi-language sites.
  • HTTP status — final page returning 200? Or 4xx/5xx?

Never worry about canonicals

InBuild emits self-referencing canonical tags on every page automatically. No duplicate content issues, no redirect chains, no manual configuration.
