Welcome to the Q&A Forum

Hi, We are using custom wordpresss posts to showcase different services we provide, these are then grouped within custom archives. These custom archive pages are our main keyword landing pages and traffic generators (although ranking is fairly average). It's come to my attention that these custom posts have also been listed in the wordpress standard categories, with an identical title, excerpts and near identical urls as the custom archives. This appears to have been the case for quite a while. We are concerned that this is may causing duplicate content issues and unsure how to proceed. We have been advised to simply no-index the redundant 'standard' categories but as they have been indexed for some time we are cautious of causing any upset with search engines (although the categories are indexed they are not ranking for any major keywords) Are we best 301ing the redundant category to the custom archives or using a canonical tags or simply no-indexing the categories like other archive pages? Any advice is aprreciated Many thanks BC
