First and foremost welcome to the forum! Now lets look at your question and why you probably should not have asked it...
First Reason- If someone has great results with a clickbank product they do not come to the forum and tell everyone. Imagine, someone comes here and says Im promoting ....... and in the last month I have converted 1/10 clicks. Can you guess what would happen next? Well now that person would have hundreds if not thousands more people competing with him. Not very logical.
Second Reason- Im sure many people have ebooks or products in the clickbank marketplace. Now how easy would it be for me to come on here and say "Oh ya I am promoting ....... and I am converting about 1/5 clicks, its the best product I have ever promoted." But as it turns out the part I didnt tell you was that its my product and im trying to get people to promote it. And guess what, I have never sold any copies because its garbage.
So here is what you need to do. You need to find a way to get some quality traffic, my recommendation is to start researching SEO ( search engine optimization ). Whether its black hat or white hat it doesn't matter, your already at the right place. Now once you know more about SEO you can start getting organic traffic to your sites promoting clickbank products. You will get your own clicks and see which product is best to promote. Then your going to find your gem. Now take what you did and duplicate it over and over and over and over. You going to come back here one day and see someone post this exact same question and your going to laugh.
Please do not take what I said here to be an easy task. Its going to take a while and its not going to be easy. But once you start seeing the sales on your CB account everyday you will see that the hard work was worth it.
Now look on the left hand side of this site. There are two links you will want to click on. White hat SEO and Black Hat SEO. Start reading until your eyes bleed.
Hope this helped my friend!!! I wish you great success!
