About the Bulk Canonical Tag Checker

This tool inspects <link rel="canonical"> across many pages, resolves relative URLs, detects multiple or missing tags, and verifies the HTTP status of the canonical target.

Find missing or multiple canonical tags.
Validate canonical URLs (absolute, resolvable) and flag off-site or non-self canonicals.
Check target HTTP status (200, redirects, or errors) to avoid wasted signals.
Export a CSV for quick sharing and fixes.
