profit share for attracting subscribers to signal

 
Does anyone know the answer to this:::::::::: if you offer a set percent for example 30% to affiliates on mql5 to promote your signal, does the affiliate then get 30% share of the subscription price every month or is it a one off payment to the affiliate of 30% of 1months subscription but no more if that subscriber stays with the signal provider for many more months
