Canonical Link Element From Google
February 25th, 2009 by hbond{{chris}} Google announced the Canonical Link Element tag and Ask! is supporting it too.
To help webmasters deal with duplicate content within their own site Google has developed a canonical link element. The new element allows webmasters to tell Google which version of a page of content is the master page. Google can then easily ignore the others.
For more on this new announcement have a look Matt Cutts post on the Google Webmaster Central Blog:
