Use social media. Posts asking people to join your team won't likely produce results, but if you're clever, you can use social media to generate interest in your business and possible leads. For example, if you sell weight-loss products, you can promote before and after pictures on Pinterest or Instagram. If you sell makeup, you can post tutorials on YouTube that you share across social sites.
On the part of the company who sells a certain product via MLM, the advantage is really huge. Imagine if you have an unknown product that came from the wilderness and nobody has really ever heard. Since you are an MLM type of guy, you made a simple conversation with a few of your neighbors and relatives and let them know about your newly discovered product.
