Most of them fail because they don't know anything about marketing.
Whether you are selling you your products or someone else's products, you have to know how to do online marketing. Once you understand how to place an ad in front of a very targeted audience and how to convince the customer to buy through a sales funnel, you can make money fast.
With affiliate marketing, you are simply using a product already selling which is in my opinion, 5 times easier than starting your own ecommerce store.
I want o know your stories and how successful others are online so that we can all help each other creating passive income and living a life of freedom.
Have a nice day,
