Geotargeting is a great start to that. I want to add to that dayparting as I want to target the business customer and avoid students doing homework at night.
I figure the simple version of this is to assume that since Asia is 12 hours ahead of us, I go to the scheduling section of AdWords and choose 9 PM to 9 AM.
Of course, AdWords tells me that my campaign ends before it starts so it does not allow that.
I'm on the east coast and am guessing their timezone is ~12 hours ahead of us.
Does geotargeting auto adjust for time in the targeted timezone?
