On January 18th, I ran another ad campaign with AdMob. My first campaign was run in last december (see: http://buildingiphoneapps.blogspot.com/2009/12/admob-campaign-finished.html). The reason I ran those ad campaigns was that I was trying to lift the sales of my iPhone application. So, what happened? I first ran an ad campaign via AdMob at the beginning of december 2009 then another one yesterday.
How those two ad campaigns compare ?
The first campaign was run in the US and was for a very broad audience with three slogans.
The second campaign was run in Canada only and was targeting iPhone 3G and iPhone 3GS devices only.
