Duplicate URLs

[Peter Knight]

One of my blogs seems to be accessible from multiple URLs and it's affecting my clients SEO.

For example, using the following URL structures, I can access the same page.

http://www.domain.not/blog/page2/

http://www.domain.not/blog/posts/page2/

The correct one is probably the second one as all posts are children of blog. 

My actual blog structure is as follows

Blog

- Posts

   -- Post A

   -- Post B

   -- Post C

   (etc)

- Tags

- Categories

I have pagination enabled on a template called blog-posts which is applied to the Posts page. 

I'm not sure though why the double URL is occouring?

I think this is down to the blog-posts being applied to 2 pages. Both Blog and Posts are using this template so that's my mistake!
