waht is the key to affiliate marketing?

[Angie]

To be a super affiliate you have to know the product you are going to market. You have to believe in it so that you can let others know the benefit to you.
You can either choose a less competitive niche to dominate which might have less traffic or you can choose a highly competitive niche like weight loss and still make it because of the high traffic volume.
Secondly your product must have a great sale page. For example if you want to market clickbank products you have to go to the sales page to check it out yourself to see if you will buy from such a page. You have to test the sale page to see if all the links work.
One Internet marketer you can learn a great deal on affiliate marketing from is Ewen Chia you can check his super affiliate program from the link below.
He has taught a great number of marketers including me about affiliate marketing.
When you find yourself a winning sales page then you start driving traffic to it either through forums, criagslist , yahoo group etc.
