but are you seeing clicks comparable to text ads? I generally feel that people don't click on image ads, as well as they do on text ads.This is one reason why image ads pay you more per click...
Head to head test for me over about 1.5 million impressions, image ads pulled just under twice the CTR of text ads. These were ad units set up to be image only or text only, and rotated evenly. YMMV.
Image ads pay more per click because the advertiser has to bid enough to out-bid three or four text ads in order to run. Trust me. I'm an advertiser. I know.
