Hello, it depend of traffic that you send.
For me the - best sponsors are not overused just everybody see brazzers, rk, bangbros... They are most used have good ratio but in same time most clients see their matterials every day.
I try micro niched sponsors like: VIPissyCash
VIPissyCash
For exampe they have better ration right now for me. and again it depend form traffic that you have.
