Multi-Level Marketing (MLM) is a business model that involves recruiting individuals to become distributors of a company's products or services. These distributors then earn commissions on their own sales as well as the sales made by the people they recruit into the business. MLM is also known as network marketing, referral marketing, and direct selling. The MLM industry has a hierarchical structure where distributors are organized into levels or tiers. Distributors at the top of the hierarchy are responsible for recruiting and training new distributors, while those at the bottom are responsible for selling the products or services to customers. MLM companies typically offer training and support to their distributors to help them succeed in the business. MLM has been a controversial industry due to its resemblance to pyramid schemes, which are illegal. However, MLM companies operate legally by focusing on the sale of products or services rather than solely on recruiting new distributors.
