awhile back, google decided it would be better to ram mobile traffic down your throat. ie when you buy from them mobile is included by default. thats not to say that mobile won't do well for you. you'd be best served to separate this. on the google content network you'd be better served to create specific placements instead of using keywords. especially in your case. you can get good traffic from the content network it just takes a bit of learning/tweaking.
