Testing Facebook ad sets on a limited budget?
I have around 15 dollars I can spend per day testing ad sets to find an audience for my product.
My question is: how can I be effective at testing ad sets while on a limited budget?
I'm unsure how many people should be targeted within each ad set. I don't even know if it is a good idea to group together similar interests.
Any guidance would be really appreciated. Thank you for reading!
