Is there a way to see how uniques vs. impressions and which sites are getting clicks?

I *think* the number above all your stats is raw numbers, and the actual numbers when you click on "details" are uniques.

As for tracking sites - if I'm not mistaken you have to designate channels to each site you want to track.

There may be another way I don't know about, though.
