Google Goes Canonical +

Google announced a nice upgrade this week for people who have duplicate content on their sites because of catalogs.  Often times the same content will appear more than once depending on how you searched for something.  So you may get the same content for a pair of brown shoes by filtering down to shoes>brown or shoes>men’s.  You can now add a tag <link rel=”canonical” href=”">  inside the <head> tag and Google will understand that all of the duplicate pages refer to this url.  This will also help shore up PageRank to this one particular page rather than it being diluted to all of the pages with the same content.  You can read more about the particulars on the Google Webmaster Central blog.
