Just a thought if sub folders reduce the PR by one (1), does anyone have any ideas about using sub domains for this purpose?
EG instead of using yourdomain.com/casino-forum/
use casino-forum.yourdomain.com
Years ago sub domains were some what frowned upon, however, I’ve seen a number of these aquire top (spot 1) SERP’s at many SE’s lately.
Any one with any ideas?
