I have a Placement Targeting campaign consisting of all kinds of "nice" looking banners, the placement is "internet marketing" or "affiliate marketing" related sites.

My problem is that with google image ads and placement targeting, i dont have ANY idea how "good" my campaign is and whether my current bid is ok.

I just see that i have a rather mediocre number of impression, and VERY few clicks.

How can i optimize my banners/placements and get more impressions/clicks?
