Matt Cutts from Google shares tips on the new rel=”canonical” meta tag that the 3 top search engines now support.

Google, Yahoo!, and Microsoft have all agreed to work together in a “joint effort to help reduce duplicate content for larger, more complex sites, and the result is the new Canonical Tag”.

Example Canonical Tag From Google Webmaster Central blog:

<link rel=”canonical” href=”http://www.example.com/product.php?item=swedish-fish” />

You can put this link tag in the head section of the duplicate content urls, if you think you need it.
