Ok I have seen this in practice in a few themes where, as an example, one uses the "About" page as an embed in the sidebar or footer of a site. Basically a bit of a hack way to get multiple content areas on a single html page. One uses:
to do this. I have found it quite useful but have been weary to push it too far as I have been wondering about the SEO impact of this as each "content area" created this way exists as a page on it's own creating duplicate content across the site.
Any suggestions or comments? I can't see having multiple content, especially if duplicated on same page (picture About page with the About content also in the footer) as being anything but bad.
Is there any way of creating post types that aren't "published" but can still be queried as areas of pages?
