Canonical tool.

Use the canonical tool to check if a page has a canonical tag and to find out which page should be index by search engines based on the canonical location.

The syntax used for a canonical tag:

  • HTML Mark-up = <link rel=”canonical” href=”http://example.com/page.html”/>
  • HTTP header = Link: <http://www.seoreviewtools.com/canonical-url-location-checker/>; rel="canonical"

The canonical tag is supported by:Google, Yahoo, and Bing.

UPDATE: This tool now also supports / checks the HTTP Canonical headers

      Update:

      • Changed HTML encoded canonical HTTP header on the test page to none-HMTL encoded characters (as it should be).
      • Updated corresponding detection parameters for canonical checker.

      Special thanks to Klaus S. Madsen for pointing out these issues.
