Lets imagine i have 20 topics to deal with. What I exactly want is to have a wordpress blog and a forum for each one of them.
I need your advice on going for either 20 different subdomains or 20 different sub directories. Which of the following option would be a better option:
A) blog1.mydomain.com & forum1.mydomain.com ... or
B) mydomain.com/blog1 & mydomain.com/forum1 etc...
I need this inputs from page rank perspective(see here, how PR is affected if the top level domain is not that active) and also from feasibility, performance & backup view.
As it is somewhat clear that each subdomain has to grow on its own in the Page Rank view, I am inclined to create mydomain.com/blog1, mydomain.com/blog2 ....Is it possible to install different wordpress & phpBB in 20 or more sub directories. OR is there any better option.
