Affiliate marketing target group


Hello all. I am new to affiliate marketing and wanted to ask one question.
Should my target group needs to be from the country that i am (Greece) or global??


you are the middle man. Your job as an affiliate marketer is to connect a person who needs help with something, with an offer that solves their problem. To do this, it doesn’t matter where you live. So to answer your question, NO, your target group does not have to live where you live. The point of online marketing is to leverage the global power, not just stay local.
