The basic concept of affiliate marketing is easy, you are simply selling other people’s products and getting a commission for it. It’s also relatively easy to get starting with affiliate marketing. All you need is a following of some sort and an affiliate link! What’s not easy is scaling your affiliate income and maintaining a constant flow of passive income.
In summary, it’s not that difficult to make a passive income out of affiliate marketing but to make a living out of it takes a lot of work! Nothing worth having is easy.
