Doesn't this study just mean that <i>Chitika's</i> ads are half as likely to be cliked on from mobile users? It's only one data point without controlling for the type of ad. I wouldn't want to generalize to all mobile users based on just this study. Anything else out there that observed similar results?<p>Certainly for a mobile site I won't be using Chitika; instead I'll try another network. The numbers are clear :)
