Distribution is a commonly used social marketing tool under the Internet economy model. It allows you to share the services/products to your friends and earn commissions for all their future purchases.
It works in below manners, assuming you are A, and you share the product/service link to your friend B. After your friend B purchases, you can get commission rewards.
Your friend B may also apply to become a distributor, and then recommend to a friend C, after C make purchases, both A and B can get a commission bonus.
Then, C can recommend D to purchase, so ABC will all be rewarded on different commission rate.
The sooner you become a distributor, the more subordinate distributors you will have, and the greater commission rewards you can get.
