An affiliate program is one where you join the company as an affiliate, and they provide payment methods, marketing materials, etc., to help promote their product. An affiliate product is usually an individual who has invented or hand-selected a product that they can then sell on their website (depending on marketing agreements with the manufacturer). An affiliate would earn money for promoting specific products based on purchases generated through referral links provided with pay-out percentages determined by the value of each sale (usually 2-5% of each sale cost goes to purchase price) or commissions through referral link clicks 1%-50%.
