Ref = Canonical

[JustInsulation]

Does it make sense to use the Canonical statement on pages on your web site that already have the correct URL. Or, should I ask, "Does it do any harm?"

Thanks for the speedy response Streamline,

We have just rewritten our web site using a directory structure, rather than having all of the HTML pages in the root folder, and used rel=canonical on all pages, because we were/are really worried about our (fairly good) rankings being negatively impacted.

We have also used rel=canonical in the redirect pages, as we believed that this was an appropriate use of of the 'tag.'

PS

(Sorry about the earlier 'Ref' typo)

It doesn't do any harm and in fact, I would recommend using canonical tags just in case some people access your site via a link that has parameters in the URL, such as www.yoursite.com/?utm_campaign=twitter, etc. The canonical tag will ensure that the search engines are always aware about indexing the correct URL.

Also, it's important to note that the proper syntax is rel="canonical" and not ref="canonical".
