Unless you want to or want to pay someone to set up an adwords campaign it is gambling to buy annuity leads.
One, no one reaponds to an annuity offer like life insurance or medicare. So if you bought a lead it would be for something else like a social security report.
Second, annuity leads would be so valuable you couldn't trust anyone you bought them from. Not your IMO
not anybody. Think about it... a medsup lead will lead to a few hundred bucks. A life lead will lead to 300 to 800 bucks on average. An annuity lead would lead to thousands of dollars even for a lower end client and $50,000+ for a higher end client. You can't trust someone with the golden tickets.
People that buy leads with success are FE people and medsup people. Even buying traditional life leads is a tough business. People in annuities develope their own at a high cost of time or money.
