Why does Amazon offers you to become an affiliate? If some user is interested in the advertisement and clicks the link of the ad, she/he is brought to the website of the merchant or the seller directly and the individual involved in the marketing is paid for it. If the user purchases something from the website, the owner of the website for business earns a commission and percentage from it and thus, gets paid again. It also helps in cost effective promotions/ marketing and developing a good and competitive strategy with web email hosting. Without an effective and competitive strategy, a company is unable to earn the profits. It can be a differentiation strategy or a cost strategy. E-business has also resulted in better customer service.
