ClickBank is a great marketplace if you want to do affiliate marketing. It's very easy to sign up and get your affiliate link. Well, I start promoting ClickBank products since last month and earn my first 100$ by this month. First thing remember I am not new in online marketing so success came to my door very swiftly. If you are newbie I suggest you to learn first then come to online marketing. I always focus one item and promote it various way. I know there are thousands of product in ClickBank but if I promote a lot of products even 10 products at one time then it is sure I'll fail. I have used paid campaign for promoting my product. This is because paid traffic are more convert then free one. So I always focus on that. I am not use A/B testing rather then use A/B/C/D... testing. I used different banner adds and calculate which one is converting. Then only use the right one. So my suggestion to the newbie. Work hard, being focus only one thing, don't be frustrated. Success definitely salutes you.
