There are advantages to Multi-level marketing. First, the start up cost is usually very low and that is a big plus to the work-at-home mom (for example) who has limited funds to launch an online business. It is a way to get started in an online business with a very small personal investment and that is a very appealing thing for many people. Pre-packaged tools and products are provided and that saves a lot of money and relieves the need for warehousing.
Also, sales techniques are given and for the newbie to Internet marketing this is a very attractive advantage.
There are also disadvantages to Multi-level marketing. Many (if not most) people lose money in MLM activities, because they cant sell the product as effectively as they thought they could. And then there is the problem of credibility. It can become an issue, especially if you start treating friends like theyre customers.
