First, I highly advise you have at least 3 different products within one vertical that you enjoy. Then, I would build a simple landing/ sales page that will provide traffic to those three offers. You should give your affiliates 50-60% of the ebook price and keep the rest or you will be spinning your wheels. Its important to have affiliates selling for you but its also important that you, yourself know what works and how to promote traffic to your offer.
Is your ebook available to affiliates on clickbank now?
