The small business guru behind Duct Tape Marketing shares his most valuable lesson: how to get your customers to do your best marketing for you. The power of glitzy advertising and elaborate marketing campaigns is on the wane; word- of-mouth referrals are what drive business today. People trust the recommendation of a friend, family member, colleague, or even stranger with similar tastes over anything thrust at them by a faceless company. Most business owners believe that whether customers refer them is entirely out of their hands. But science shows that people can't help recommending products and services to their friends-it's an instinct wired deep in the brain. And smart businesses can tap into that hardwired desire. Marketing expert John Jantsch offers practical techniques for harnessing the power of referrals to ensure a steady flow of new customers. Keep those customers happy, and they will refer your business to even more customers. Some of Jantsch's strategies include: -Talk with your customers, not at them. Thanks to social networking sites, companies of any size have the opportunity to engage with their customers on their home turf as never before-but the key is listening.
