Sucks and it sucks, oh and it sucks. When I added the code to my forum I was surprised at how many impressions I got off mobile ads right away. But what also surprised me, and disturbed me, is that no one clicks the ads and the earnings suck. 2 days 5043 impressions, 3 clicks, and 3 cents earnings I rank this up there with useless video ads, useless search, and the defunct google referral program... The scary part is that I am assuming more and more internet surfers are using mobile devices every day, and if this is true then mobile is not good for AdSense earnings.
