how to gain pr with subdomain

hi.. i would like to ask whether can a few subdomain with same niche topics will be listed in same search results listings? i have 1 domain h**p\\:ww*.card-centre.c*m and i would like to write my own content cause i have many working years experience in this field but i would like to add more subdomain with under this domain and have a same niche, with different demographic targets.

I'd be interested to see how this works out for you. I know that google sees subdomains as unique as I was looking into something similar recently for an affiliate site with a dynamic subdomain per affiliate. Let us know how you get on :0)

Subdomain and every page is treated like unique entity, with few exceptions off course.

Subdomain and main domain always the same.More backlinks and high traffic will get a higher PR.
