Adsense on Finance site pr0

I set up adsense on my sfinances domain. I created three subdomain also on my sfinances.com domain. But my domain is still pr0 and not hug traffics. I submitted in hundreds free directories. I posted on 20 blog. All blog are do follow and blog's home pages are good page rank aslo.

Is domain page rank necessary to get adsense revenue?

What sub domains will help me?

I created three subdomains as...
1. wordpress install on sub domain.
2. Free discussion forums install on sub domain.
3. Online shopping cart.
and main website with 8-10 pages.

 

I've got a PR3 blog on my finance blog (not in english), follow the link in my signature.

 

If you managed to get traffic without PR, then PR is not necessary.

 

nah at all .. the page rank is only useful in the search engines but if you get traffic throw paid advertisements you will get the traffic to your site !
