no balance credited into the referrer wallet

currently, I’m testing the signup referral function. I have no problem with the back-end setup. But I’m not sure how it works for end-user. Because when I successfully sign up using the referral link, there’s no balance credited into the referrer wallet. The only balance for referring visitors is credited to the referrer’s wallet. Can you provide me an article for my reading to clarify my understanding of using this feature? Thank you.
