I would really appreciate if you could through some light on The conversion ratio you are getting by selling products/ebooks Thanks
The conversion rate varies from product to product. The CB marketplace with gravity option shows all the top movers and shakers.
It really depends on the product, the traffic you are sending, and a whole lot of other things - like the time of day and the day of the week. I could give you a number for one of my recent campaigns - around 9% conversions - but that is just a number and doesn't mean much.
I think to sell a product through my website I need at least 50 organic visitors to make a sale. Direct/referral I need about 150ish. So work out the CTR. Its about 2%.
