The real selling point for MLMs is that distributors can make money in two different ways. The first is money made from commissions from direct selling to consumers. And the second way to make money with an MLM is from the commissions made from sales of distributors below you in the pyramid (these are sometimes referred to as recruits or downline distributors).
A program with no or a low-quality product, or with a focus on getting paid per recruit, could be an illegal pyramid scheme. However, don't let the term pyramid throw you off. It's not the shape of the organization that makes it illegal. In fact, most companies have a pyramid structure with a CEO at the top, VPs next, mid-level managers etc. What makes an illegal pyramid scheme is the lack of a quality product, or that income is earned on recruiting, not commissions from sales.
Using link referral sites is another great way to generate free MLM leads. Link referral sites are basically a database of websites and blogs grouped in categories. After creating an account the network marketer will be asked to review up to 15 other websites and write a review of each on a daily basis. This is a great way to make new friends and expand the network of referrals.
