Affiliate link hijacking is a big problem, some people will change your affiliate URL to their own before purchasing a product so they themselves get paid the commission giving them a discounted product This problem is far worse if you are promoting to the affiliate marketers crowd as they can spot an affiliate link from 100 yards away

There is no wonder people choose affiliate marketing when they first try to start an online business Affiliate marketing is one of the easiest ways to launch your own online business, you don't need to deal with customers, keep a stock of product, worry about refunds or delivery of products, you don't even need your own website
