How and when CJ pays us? How to make it make profit for me as I have some sites already with good SERP and not making good on adsense?
You should be able to ask your account manager for help and your payment terms should be listed in your profile.
You can register with CJ and then based on your niche get approved from vendors in CJ and then create links . When users click on your link and buy something you will be paid commision. (Like 8% of the price of product)
also sometimes CJ which offer high percentage from sales (like 30% - 50%) is more likely applied than CJ of a specific niche, because of higher revenues for you.
