Promote products that are stepping stones to products you will create in the future. This is a bit more advanced, but is a great way to think ahead.

For example, I teach people how to blog, so the first thing they need to start a blog is hosting. That’s why I am an affiliate for hosting.
Let's do a little reality check here, I highly doubt you can buy traffic on Fiverr and have it convert on any ClickBank offer. Quality traffic is not acquired on Fiverr (that's for sure). Focus on building a value adding funnel like described in the post rather than looking for a shortcut. You can't just spend 5 bucks to make 40 in 5 minutes, I'd be a billionaire otherwise :).
In online affiliate marketing course, they will teach you everything you need to know to run a business online everything you need, even you'll learn how to create affiliate campaigns from scratch even if you currently don't have an audience or a list and the best part is you don't even need your own products to make money with affiliate marketing.
