Level 1 (Direct Referral):
These are people you directly refer to a program or platform. You earn a reward or commission when they sign up, make a purchase, or perform a qualifying action.
Level 2 (Indirect Referral):
If your Level 1 referrals go on to refer others, those new sign-ups become your Level 2 referrals. You often earn a commission from their actions.
Level 3 and Beyond:
This is same as previous and extends this idea to multiple layers.
