I just signed up for clickbank, I've got no experience with it at all. I'm looking to choose a product to promote and I see quite a few that have "Initial $/sale: $0.00". Does that mean if I make a sale I make no money? What would be the point of promoting that, if any? Thanks!
Usually that means the product is a re-bill and the customer will be charged a subscription fee moving forward. You might only make a little bit off the original sale, but you would make revenue each time they are re-billed (every month or whatever). If the customer holds the subscription for a long time, these re-bill offers can be very lucrative.
