As an affiliate marketer, clickbank is the best place to be on. There are quite a few special terms used in the Clickbank marketplace. All of them can be understood below :
$/sale: This is the average amount that an affiliate earns for each sale of this product. This number takes into account refunds, chargebacks, and sales tax, so it gives an accurate picture of how much you can really expect to earn from a sale over time.
Future $: This number only applies to recurring billing products (i.e., products like memberships and subscriptions that regularly bill customers over time). This number shows the average amount an affiliate makes on all of the rebilled sales. Note that this number doesn’t include the original sale amount.
Total $/sale: For one-time purchases, this number is the same as $/sale. For recurring billing products, it equals the average total of the initial sale plus all rebills, divided by the number of initial sales. To put it simply, for every new purchase of this product, this amount is the average you’d make in total over the life of the new customer. However, this is just an average; this amount is not guaranteed.
%/sale: This number typically shows the commission rate for a product. It should only ever change if the vendor changes their commission rate.
%refd: This is the percentage of sales that were referred by affiliates. This can give you an indication of how popular a product is with affiliates, and how competitive it might be to promote it.
Grav: Short for Gravity, this number represents a unique calculation by ClickBank that takes into account the number of different affiliates who earned a commission by promoting this product over the past 8 weeks. Since more recent transactions are given a higher value, this number can give you an idea of what products are “hot” at the moment, in terms of being promoted by many affiliates and making a good number of sales. However, high gravity can also indicate that there will be a lot of competition in promoting this product.

Thanks for the details, this would help many users out there.
I use to promote Clickbank products on my blog back in the day, but something happened and I just don’t use them anymore. I think it might have to do with me not making much money from them and leading my traffic away from my blog. I might go have a look at them again and see if anything has really changed.

I liked it. So much useful material. I read with great interest.
I think that I’m not a good marketer. BTW, I still believe that Clickbank is still the best marketplace for newbies and pro
