I've seen software used for newsletter subscriptions where after they subscribe they go to a page with 5 other lists they may be interested in and can subscribe to them too, so it makes everyones lists grow, anyone know what that was called?
Also wondering if there is anything out there for affiliate products just like this? Say with clickbank after someone purchases a product they go to a page with related products.
It would not only gets you heaps of backend affiliate commisions, but you get your own product sold by others a lot more (helping everyone grow their businesses).
Is there anything like that out there?
