多層次傳銷是一種廣泛應用於網絡營銷的模式，在這種模式下，參與者可以透過引薦他人來賺取佣金收入。每位參與者都有一個下線，下線的銷售獲利也會帶來一定的收入，這就是下線收入。而參與者可以通過招募更多人來建立自己的銷售網絡，每個人都有機會通過直銷來賺取佣金收入。
在多層次傳銷中，除了基本的佣金收入外，還有各種額外獎金和獎勵。引薦獎金是推薦新人加入並賺取一定佣金的獎勵，而團隊獎金則是根據整個團隊的銷售績效來分紅。此外，主管獎金也是一種經常出現的獎勵，激勵人們積極發展自己的團隊。
然而，多層次傳銷也有一些爭議。裂腦頭，也就是金字塔銷售的一種形式，往往會給人帶來負面印象。層層加碼的結構使得越是下面的參與者越難賺錢，造成人脈營銷的不公平現象。因此，多層次傳銷必須要警惕其中的壞習慣，確保每個參與者都能享受到公平的收益。

標題: The Network Marketing Model and Downline Income
Network marketing is a widely used model in which participants can earn commission income by referring others, known as downline income. Each participant has a downline, and the sales profits from the downline also generate income for the participant. By recruiting more people to build their sales network, everyone has the opportunity to earn commission income through direct sales.
In addition to basic commission income in network marketing, there are various additional bonuses and rewards. Referral bonuses reward participants for recommending new members who join and earning a certain commission. Team bonuses are dividends based on the overall sales performance of the team. Supervisor bonuses are also common rewards that motivate people to actively develop their teams.
However, network marketing also has some controversy. Pyramid sales, in which subsequent levels of participants find it increasingly difficult to earn money, often leave a negative impression. The layered structure creates an unfair environment in network marketing. Therefore, it is essential to be vigilant against such practices and ensure that every participant can enjoy fair income.
