Canonical URL

In short, a canonical URL is your "preferred" URL. For example, http://www.YOURSTORE.com/http://www.YOURSTORE.com/#, and https://www.YOURSTORE.com/ would all be valid links to your home page, but only http://www.YOURSTORE.com is your "preferred" landing page. While all these URL's would ultimately display the same home page content, the different URL's can impact your SEO results. For this reason, it's best to specify the "preferred" URL, or canonical URL for search engines.

You can update the Layout Update XML in the Design tab of the Home page (CMS / Pages / celebrity_home) and add the following:

<reference name="head">
  <action method="addLinkRel">
    <rel>canonical</rel>
    <href>http://www.YOURSTORE.com</href>
  </action>
</reference>
