As we all know there are disadvantages of affiliate marketing.
The first disadvantage is that the owner of the product that you will be promoting will be the one who earns the majority of the profit from the sale.
You will be working on commissions and therefore you will only get a portion of the sale.
Your affiliate commissions will never be as much as you could earn if you were to produce and sell your own product, then you could keep all of your profits.
An Affiliate Program is not recommended to be your sole source of income. It basically should be used as an additional way to make and earn money online.
Yes, there are affiliates who make a large amount of money as an affiliate, but these affiliates have been in the business for a while and they know what it takes to run a profitable business online.
