CPI - Up/Down -

I am concerned about the CPI of my campaign rising dramatically with a Bango audience and seeing a low ROAS … what is the average CPI for a Bango audience?

Facebook may increase the CPM cost for using Bango Audiences, it depends on many factors and is hard to predict. If CPM costs do increase then CPI may also increase, however the payment conversion rate will also increase. Paying users have a higher LTV and this should cancel out the higher CPI/CPM costs.
