It's a numbers game. Don't expect to get results working leads unless you are ready to work through plenty of them. That means buying a list and working through 100 leads and then deciding whether or not they were any good isn't a big enough sample size to make your final determination. Results with MLM Leads requires not only patience with your expectations, but also coming to the full realization that QUANTITY is what is going to bring you the result you are looking for in your recruiting efforts. Don't even commit unless you're willing to commit.
Sales leads are generated on the basis of demographic criteria such as FICO score (United States), income, age, household income, psychographic, etc. These leads are resold to multiple advertisers. Sales leads are typically followed up through phone calls by the sales force. Sales leads are commonly found in the mortgage, insurance and finance industries.
