Targeting Facebook users
I'm selling Ts and ive got several niches but im wondering whats the best way to target the users? ive got one aimed by race for minorities but should it also include people who like to buy Ts online? how about by income level? politics? credit card holders? college graduates? etc do people who are richer buy more $20 Ts than someone who is poor or is it the opposite? How about by age 18 to 65? or 25 to 55? tips appreciated.
