Multi-level marketing is a strategy that some direct sales companies use to encourage their existing distributors to recruit new distributors by paying the existing distributors a percentage of their recruits' sales; the recruits are known as a distributor's "downline." All distributors also make money through direct sales of products to customers. Amway is an example of a well-known direct-sales company that uses multi-level marketing.
Multi-level marketing is a legitimate business strategy, though it is controversial. One problem is pyramid schemes, which use money from new recruits to pay the people at the top, often take advantage of people by pretending to be engaged in legitimate multi-level marketing. Pyramid schemes can sometimes be spotted by their greater focus on recruitment than on product sales
