Hi everyone. I started an AdMob campaign on Friday. My banners were approved and my campaign (and banners) are enabled. However, I have yet to see a single impression. I'm starting to wonder if maybe I am bidding too low? I started at 2 cents, raised it to 3 cents, and then raised it to 5 cents. I'm targeting the US. Any ideas? Am I just bidding way too low? I don't see a way to contact AdMob support to ask them so I thought I would ask here. Thank you in advance!
