When deciding whether to give you their business, prospective customers trust one source of information above all others: their peers. To sell more, you need to get your current customers marketing and selling — advocating — for you. First, find the core customers who are passionate about your company. One way to do this is by asking the “net promoter” question: “How likely are you to recommend us to a friend?” Then, for those who respond with “highly likely,” make it easy for them to do so right then. Give them the option to easily post a recommendation to their Facebook friends, LinkedIn connections, and Twitter followers. Try giving them the tools to write a product review on a site important to your market. Or make it simple for them to upload a video singing your praises.
I believe Verizon uses this kind of strategy - word-of-mouth. It is obviously the most powerful tool a business can have. We buy things according to suggestions of our neighbors, friends and family because they have already tried it. TRIED and TESTED as they say. But what if you are advertise a book? I am currently reading Vivek Sood's The 5 star business networkwhich is all over Goodreads.com . It is about different business trends that can help students and business execs. But what is a good book if no one reads it. Do you have any idea how to promote a book aside from book reviews?
