hey, i have Wordpress blog, about domain please see it Domain name Blog tags and categories????is that douple contents?? 2nd question ... do you see any seo error i can edit??? please help Thanks
Yes it can be duplicated content, but you won't get penalized for that. What can happen is that these category or tag pages will rank higher then you article pages so if you see unwanted results you may put a noindex, follow tag on the tag pages. So it will not be indexed, but the links in it will be followed.
