This contribution will add the new canonical url link tag to your osCommerce webshop. The canonical link tag was recently introduced by Google, Yahoo! and Live and tells the search engines which URL it should have for the current page. This will prevent that content available on irregular urls will not be tagged as duplicate content.
This contribution will improve indexation of your website and prevent duplicate content.
