SE Questions: URL & submitting
 

Two quick ones:

I'm looking to set up a series of niche specific pages that I want to submit to SE's. I'd like to submit each page individually, even though they're a similar setup.


A) Should I buy unique domains for each page OR can I run them all off one domain without SE's looking at it with less weight?
B) If I run them off one domain, is it still okay to subit them individually?

Any help you can provide would be appreciated! Damn, I hate being new!
