If you’re a blogger, I recommend signing up under another blogger because they help you sell and market online rather than having in person parties or bugging your friends. If you want to join our team, contact me through my contact form or ping me on Facebook. There is no monthly minimum order required so you’re not paying while you’re learning, so this is the only MLM that interests me at all. Plus I’ve been a happy customer for many years.
At the other end of the spectrum is buying leads. This is also not the best option since it can be very expensive and may result in leads that may not actually be interested in your products or business. These are not great leads, either. The best leads will always be the ones you generate yourself—people who have shown some sort of interest in what you have to offer.
Many MLM companies recommend starting with a list of 100 people you know, called your warm market. Although it's not a bad place to start when looking for customers and business builders, the technique could also backfire and get to the point where you're annoying friends and family. You're better off spending your time finding people who are interested in what you've got rather than trying to convince your commuting buddy to sign up when he doesn't want to.
