Say if you find a subscription product to promote with PPC, it pays out 25% commision, the longer length subscriptions and higher level subscriptions of the product make it worth your while if successful with it but the lower level and shorter subscriptions of it mean little profit, would you still go for promoting this through PPC? For example a 1 month subscription of a lower level would cost the subscriber less than $10 But the 12 month subscription and of the, lets call it advanced level will cost the customer over $300, so clearly room for profit there. With a two word search phrase of the higher volume words being around $0.70 - $0.80 CPC It does have a 7 day free trial available, you dont get commisions on renewals, just on the initial signup. Wondering what your thoughts are on this? my thoughts are it could balance out and longer more expensive subscriptions making up the profit, but in the other direction, if loads of people go for a monthly subscription and on the lower level then its not exactly a winner.
