Electronic Word of Mouth (eWOM) is a form of buzz marketing and it can become viral if the message is persuasive or funny enough. In eWOM we focus on person-to-person contacts that happen on the internet. You may think this is new but in fact it's the oldest type of marketing we know. Second is product development and quality control. eWOM can help a company to understand consumers' reactions to its products and services in a better way. However, eWOM communications can reveal information to companies' competitors and spread information about product and service flaws. Using word-of-mouth marketing helps build positive feelings about your products and services, and that helps build your company's brand. Providing resources—such as tips, information and articles—gives your customers an easy means of sharing information about your company while establishing your brand.
