Facebook used to be an easy source to tap into, but since they have formed a public company with shareholders who need to be kept happy, Facebook have changed their Terms of Service several times recently and have clamped down on a number of things that used to make lead generation relatively easy. They have discouraged siphoning off clients to external web sites and CPA offers, and have raised the cost of advertisements that do this. It remains a viable lead source however.
Get them to watch a company presentation and then ask them what they liked about what they saw. One of the, if not THE, best question to ask a bought MLM lead is: “What has recently changed in your life that has you open to a home business?” This question is frigging awesome to get them to open up. If your upline has not provided you with a place to purchase MLM leads for practice and to work with, I have a partnership with Responsive Data where you can buy MLM leads on this site. I have personally bought from this site and the leads are good quality but like I said, you STILL have to treat them like a lead, not a laydown sale. My favorite type are the local leads as I think it is a bonus if I can say I live in their area.
The reason I started Apache Leads way back in 2003 was that I was a Diamond level distributor for a San Diego based MLM company and had quite a large business. None of my associates had any access to leads, so that's how we got started. The demand for leads grew so fast that I had to focus on getting quality, affordable leads in ever increasing numbers.
