Because you see, affiliate marketing is simple to do, and requires a small amount of time to profit in, as compared to creating your own products. However I do recommend that you jump on the product creation wagon once you've got some skin in the game kiddo.
Affiliate marketing is basically you marketing someone else's product in order to receive a percentage of the sale. It's very simple and I won't over complicate it.
Now here is a kick-butt strategy that you can use to start making money with affiliate marketing if you are completely new.
First thing to do is select a niche that you want to start marketing in. Make sure you choose something that you actually enjoy talking about, and something that has money being spent in it.
Next you will have to set up a squeeze page and an email marketing auto-responder service like aweber($1 trial for 30 days), or getresponse(free for first 30 days), or even mailchimp (mailchimp is free).
Next go and select an offer that is in your niche that is converting well. By that I mean, an offer that people are actually buying and spending money on.
To find products you can go to clickbank.com, clicksure.com, click2sell.eu, warriorplus.com, and jvzoo.com for example.
Once you select your product, you can then put the affiliate offer on the thank you page after people optin to your squeeze page.
Now you build a list of subscribers and then you also hit them with the affiliate offer as soon as they opt into your list.
You'll make money by sending more and more people to your squeeze page. Remember, the more traffic you get the more money you make.
I hope this simple lucrative strategy helps. Please let me know if you have any questions.
