what is the normal conversion of Cb products

I have a site receive 100 to 150 targeted visitors everyday，but 2 week have past， the conversion is still zero, is it normal for me ？

Average clickbank conversion is in the 1%-5% range. I know that is a pretty wide range for an average but I guess the 1% applies to newbies and the higher percentages apply to those who use email marketing, highly targeted landing pages etc.

Bottom line is that conversions for clickbank products in general is pretty low. There are a few exceptions of course.

Post some more info. How many hops, how long do they stay on the site, where is the traffic coming from, etc..

Mostly depends on two factors. The quality of your traffic and the gravity of the product you are selling. You can send 10k random visitors to 1 product and never get a single sale.

If you are getting highly targeted traffic and still not converting though, there is a problem either with the information you are providing or the seller is not making the necessary emotional connection with the prospect.
