Everyone has to start somewhere in life as far as I am concerned.
It simply isn't possible to know everything there is to know about affiliate marketing from the word the go.
Whilst it is possible to research the topic online, I have found it beneficial to be part of communities that give you the foundational knowledge you need to get you started fast.
There is a company whose services I use that can provide you with the knowledge you need to get started as an affiliate marketer.
You will get 10 lessons on affiliate marketing absolutely free. What I love is that you can also build two websites with them absolutely free.

Now I do know that at times, we can be skeptical about the benefit of partnering with a company.
So if you want to know whether their training in affiliate marketing is of any use, I highly recommend that you read this article from a fellow member with current examples of members who have benefited from the training.
