Network marketing, also known as multi-level marketing (MLM), is a business model where a company sells products or services through a network of independent distributors or representatives.

In network marketing, the distributor earns a commission on sales made by themselves and the sales made by the people they have recruited into the business, known as their downline. The downline can consist of multiple levels of recruits, hence the term "multi-level marketing."

The main goal of network marketing is to build a team of distributors who sell the company's products or services and recruit others to do the same. Distributors earn commissions on their own sales and the sales of their downline, which creates an incentive for them to recruit and train new team members.

Network marketing companies typically provide training, support, and marketing materials to their distributors to help them grow their business. The distributors are responsible for finding customers and promoting the company's products or services to them.

The network marketing business model has both its advocates and detractors, with some people believing it to be a legitimate business opportunity, while others view it as a pyramid scheme. It's important to do your research and choose a reputable company before getting involved in network marketing.
