Welcome to the Q&A Forum

Hi, my first question and hopefully an easy enough one to answer. Currently in the head element of our pages we have canonical references such as: (Yes, untidy URL...we are working on it!) I am just trying to find out whether this snippet of the full URL is adequete for canonicalization or if the full domain is needed aswell. My reason for asking is that the SEOmoz On-Page Optimization grading tool is 'failing' all our pages on the "Appropriate Use of Rel Canonical" value. I have been unable to find a definitive answer on this, although admittedly most examples do use the full URL. (I am not the site developer so cannot simply change this myself, but rather have to advise him in a weekly meeting). So in short, presumably using the full URL is best practise, but is it essential to its effectiveness when being read by the search engines? Or could there be another reason why the "Appropriate Use of Rel Canonical" value is not being green ticked? Thank you very much, I appreciate any advice you can give.
