Should I include "worldwide" location while making facebook ad ?
I am working on online medical lectures and want to promote my video lectures with facebook ads. So there is no need to target a specific location. I want medical students and professionals to view those lectures globally. Is it wise, economically and strategically, to chose worldwide audience rather than targeting few locations or countries. Some people say that if you target worldwide audience your ad will be shown to only those locations where ads will cost less (3rd world countries for example)
