Google AdWords mobile bid adjustment
Do I understand correctly that Lulu works ok with computers and tablets but not with smartphones (because smartphone screen is too small for wide Lulu cart)?
Is it a good idea to lower Google AdWords bid for mobile devices -100% so that smartphone users would not see my ads at all? Or maybe lower it but not all 100%, because it is hard but possible to do a Lulu purchase from a smartphone? If so, how much percents it should be lowered?
