The book let me know a truth: for political candidates, when they burn their supporters up and spreading the word, it is called "energizing the base". Companies and customers are in the same situation. It is a powerful way to energizing the base and use the relative groundswell to let your customers spreading the products or services to more people. In chapter 7, the social media strategy leader Josh Bernoff told us how to charge up your best customers and let them use social media technologies to recruit the people around them through positive word of mouth, such as using ratings, reviews and on-line communities.
The word of mouth succeeds because it is believable, self-reinforcing and self-spreading. I think no company will say bad thing about their products or services, so when customers see the advertising or the post on Facebook about introduction or recommendation of the products and services, they may not believe all they showed is true. But you can image if someone really used it before, and told you it's wonderful and recommended you to try, I believe you will. That is what we call "the word of mouth".
I can give an example of myself. I love traveling, which means I should often search the flight and hotel information on the web. The web I often use is "cheaptickets".
so I can write what's my feeling about this hotel, and then can give the suggestion to the following customers. Before I choose the hotel or activities in my trip, I also will read the review about them and then make a decision.
It totally showed that the value of word of mouth means much, so many companies would like to recruit volunteer by giving them samples or coupons for new products, and let them write the reviews. The positive reviews will help them spreading their products, and the negative reviews also can help the company do some good change to improve their product. In life, people would like to share the good things to family and friends, so it is worth to energize them. Many companies even create a community for their customers, so people can talk about the product or service together and solve each others' problem.
