As I found some user-agents of mobile phones/pdas in my logfiles, I thought maybe targeting them seperately would be interesting and reveal some data about searchvolume on these devices.
I set up a adwords campaign (for mobile users only) with my most used keyphrases but didn't get a single view in a month (I adjusted my cpc and budget a few times to meet the 1st page amount necessary, but no success).
