Link Canonical Plugin will help you to get rid of duplicate content on the site, indicating the preferred URL to search engine robots.
If your site contains multiple pages with largely identical content, this plugin provides you with the URL returned in search results. At the same time you can be sure that all characteristics (for example, reference weight) will be transferred on the desired page.
For example, the same products that have different sort order are displayed on category pages:
-
http://site.ru/category/kompyutery/
http://site.ru/category/kompyutery/?sort=name&order=asc
http://site.ru/category/kompyutery/?sort=tota&order=desc
To prevent the duplicate content from display in search results you should use the tag from sort order pages <link rel="canonical" href="http://youdomain.com/..." /> on the category page. It can be done with the help of Link Canonical Plugin.
Plugin features:
-
automatic generation of tag value <link rel="canonical" href="http://youdomain.com/..." />;
ability to add exceptions to the pages with get-parameters;
