Welcome to the Q&A Forum

Hi Marco, I took a look at your page at http://www.beautifulpuglia.com/it/linea-costiera/isole-tremiti.html Looks like you've got the canonical in place okay here. The next step is to add the canonical on every page that is a duplicate of this page. And you want to make sure to point to the right page. Let me be clear: Every page that is a duplicate of this page should have the same canonical. In this case: <link rel=”canonical” href=[”http://www.beautifulpuglia.com/it/gargano/isole-tremiti.html”/](view-source:http://www.beautifulpuglia.com/linea-costiera/%E2%80%9Dhttp://www.beautifulpuglia.com/it/gargano/isole-tremiti.html%E2%80%9D/)> You can find the other pages you need to add this tag to in your SEOmoz report. In each duplicated content report, it will list the number of other pages that are duplicates. Simply click on the number to see the URLs. I'm not a Joomla expert, but webmasters I've talked to have expressed that other platforms such as Wordpress and Drupal are much more accommodating of these types of fixes. There are some various plugin modules you can use, but you'll have to select one appropriate to your configuration. Here's a good resource from Dr. Pete: http://www.seomoz.org/blog/duplicate-content-in-a-post-panda-world Hope this helps. Best of luck.
