Canonical URL

A canonical URL is designed to eliminate one of the most common problems that websites experience – duplicated content. The canonical URL was warmly received in 2009 by large search engines, including Google, Yahoo and Bing. It’s important to know that duplicate content in a website impedes promotional efforts being performed on the website, and in fact, the canonical URL tag determines the preferred URL among those that contain similar or duplicate content. Almost every website, including commercial websites, contains duplicate and similar content, which is why the tag filters the relevant data when making the page available for users.
