Stupid question about SE popularity.
 

Ok, I'm sitting here looking at a list of domains that are found in search engines from a site I am registered to.

My question is when I find one and it says it has 200 or whatever links to it in Alltheweb for instance. How can I see how it ranks for certain keywords?

there is software that can check this although SE's frown on that pretty heavily

just look at the website in question and try to find out which keywords they might rank for

then check them in google
