Answer 1

Google gives ranks to pages e.g

a) site.com/dir/
b) site.com/dir/?q=875445
c) site.com/dir/?q=adssda

a = page, b = different page, c = another different page

if you want to check ranks for pages on the go

you can download an extension for google chrome called SEOquake it lets you see all kinds of stuff for the current page that you are looking at.

SO it doesn't matter how your pages URL are like,if it's a different page than it's a different page e.g different page rank
