Because of the nature of recruitment and the dream of living the life of riches, it is no stretch to the imagination that sometimes, the real picture gets blurred between the lines. Also, MLM is notoriously known for getting you on the bad books of friends and family. This is of course a general stereotype against the industry and not a concrete consequence.
Multi-level marketing is a strategy 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 the 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.

If you want to go the technological route, it’s not a bad idea to check out what is out there in lead generation software. You will be able to more effectively send e-newsletters, organize your contacts in a database, and exploit a variety of features which will help you to generate more network marketing sales leads. Implement these step by step, and before you know it you will have a well-developed marketing strategy that helps you to reach out to prospects in a more personalized way.
But more than product selling MLM/NM provides a lucrative option to earn great part/full-time money and most importantly passive income. Once you sign up somebody in the business by selling a product and he signs-up someone else and so on, you create a network of people who are recommending a product or offering a business opportunity thus generating sales for the company and also earning 10-125 of the total sale happening through your network. In MLM u get percent of every sale that happens in your group of people directly (when u personally sell to someone) or indirectly (your team member sells to someone). So, if you have a network of 10 people and your team sold product worth $1000 then you would earn $100-150 as commissions. For direct sale u get more money.
The Internet has made it so easy now. In the old days you had to actually visit people, or at least call them, to pitch your fabulous new opportunity. Face-to-face marketing is still practiced, but it is not so common these days. Besides, no one really loves the idea of having someone over, so they go online where everyone can be as safe as they want. They create sites with videos, testimonials, and pictures.

The term “MLM company” isn’t exactly accurate because the company is not necessarily defined by the fact that it uses a multi-level marketing structure. Instead, a good MLM will be a product-centric company, meaning that it will be, for example, a cosmetics company that uses an MLM structure. Test the product of the company you are interested in; the product must be something that you would willingly advertise even if you weren't working for the company.
MLMs are successful because they provide tempting possibilities — the more you recruit, the more you sell, and the more you make. The possibility for income seems almost endless. However, only a few companies can make this dream a reality. So how do you spot the good ones from the bad ones? Look at the product. If the company has put time and money into creating a valuable product, they will put time and money into selling it.
