I have wordpress integrated blog on my site. I use moz tools as well. When i checked, the tool shows many pages as duplicate from wordpress. ie mysite. com/post_name" has duplication issue with "mysite. com/tag/keyword" and "mysite .com/2010/posts" so on. How to avoid this issue? I tried yoast plug in. But it doesn't fulfill my requirement. Is there any options to add canonical to each section? Please advice.
