If an affiliate changes the terms of its program, your revenues could be directly affected. Choosing the wrong affiliates can also be problematic if your blog or website audience doesn't feel compelled to buy their products or services. With the affiliate-marketing industry experiencing a boom, you’ll also have to contend with competition from other marketers shilling the same affiliate products.
But the biggest factor that determines how much money you will make, is joining a training program that will help you success. It is very hard to expect success right away if you are a beginner and all alone. The best program that offers you the information, help, tools and support to succeed is Wealthy Affiliates. Some Wealthy Affiliate members are already making over $8000 a month after only 6 months of being a member.
