Word of mouth marketing

Word-of-mouth marketing (WOMM, WOM marketing), also called word of mouth advertising, differs from naturally occurring word of mouth, in that it is actively influenced or encouraged by organizations (e.g. 'seeding' a message in a network, rewarding regular consumers to engage in WOM, employing WOM 'agents'). While it is difficult to truly control WOM, research has shown that there are three generic avenues to 'manage' WOM for the purpose of WOMM: 1.) Build a strong WOM foundation (e.g. sufficient levels of satisfaction, trust and commitment), 2.) Indirect WOMM management which implies that managers only have a moderate amount of control (e.g. controversial advertising, teaser campaigns, customer membership clubs), 3.) Direct WOMM management, which has higher levels of control (e.g. paid WOM 'agents', "friend get friend" schemes). Proconsumer WOM has been suggested as a counterweight to commercially motivated word of mouth.

George Silverman, a psychologist, pioneered word-of-mouth marketing when he created what he called "teleconferenced peer influence groups" in order to engage physicians in dialogue about new pharmaceutical products. Silverman noticed an interesting phenomenon while conducting focus groups with physicians in the early 1970s. "One or two physicians who were having good experiences with a drug would sway an entire group of skeptics. They would even sway a dissatisfied group of ex-prescribers who had had negative experiences!"

With the emergence of Web 2.0, many web start-ups like Facebook, YouTube, MySpace, and Digg have used buzz marketing by merging it with the social networks that they have developed. With the increasing use of the Internet as a research and communications platform, word of mouth has become an even more powerful and useful resource for consumers and marketers.

In October 2005, the advertising watchdog group Commercial Alert petitioned the United States FTC to issue guidelines requiring paid word-of-mouth marketers to disclose their relationship and related compensation with the company whose product they are marketing. The United States FTC stated that it would investigate situations in which the relationship between the word-of-mouth marketer of a product and the seller is not revealed and could influence the endorsement. The FTC stated that it would pursue violators on a case-by-case basis. Consequences for violators may include cease-and-desist orders, fines or civil penalties.
