In an affiliate marketing business, you only have to promote the affiliate offers of the network you have joined. In comparison with dropshipping where you have to cater to customer support, affiliate marketing doesn’t have any of those issues. Customers only get redirected from your website to the ecommerce [merchant] store through the links and you get a commission.
All CPA marketers put their eggs in one basket. I’ve seen plenty of the greats go from zero to hero and vice versa several time in their careers. The smart ones learn to build their own business in the process and pimp their products to CPA newbies (where the real money is). So if your only focus is to make the most money you can I would advise you not to spend it all because that business model won’t last.
Honestly speaking, both dropshipping and affiliate marketing requires hard work to start. Most people enter online marketing thinking that they can easily get rich by making the website and streams of income will start popping out in no time. That is a grave mistake. Whether it is dropshipping business, affiliate marketing, or any other online business, it requires consistent effort to grow the business.
