Validate canonical URL tags.
Canonical differs from expected — verify this is intentional.
Canonical tags tell search engines which URL is the preferred version when duplicate or similar pages exist (parameters, print views, HTTP vs HTTPS).
This tool compares your expected canonical URL against the canonical found in fetched HTML or a simple URL pair check.
Fixing canonical mismatches prevents split ranking signals and wrong URLs in search results.
Paste the URL you are testing and click Fetch page HTML.
Enter the single URL you want indexed as the primary version.
Green = match, amber = missing tag, red = different canonical found.
Update CMS canonical, add redirects, or fix conflicting tags.
Consolidate signals on one preferred URL.
Essential for sort/filter URLs and tracking parameters.
Verify HTTPS and www migrations point to the right canonical.
One check beats reading raw HTML for every template.
