Let's say I am having a tag page at wordpress like
http://www.mysite.com/tag/tag_name/ having 2 blog posts A & B and a category page like
http://www.mysite.com/category/category_name/ having blog posts B & C. The content of post B 'll be shown on both pages and the permanent link of post B too. Can this example be a case of Duplicate content as the full post B is being shown in various pages along with other posts which are different in each page?
Those pages are already are
nofollow except permalink of the blog posts but still they content is being duplicated all over. I wonder if it would have impact on my seo?
