WOM marketing
Referral marketing is a method of promoting products or services to new customers through referrals, usually word of mouth (WOM). Such referrals often happen spontaneously but businesses can influence this through appropriate strategies.
Referral marketing is a process to increase word of mouth marketing by encouraging customers and contacts to talk as much as possible about a brand or product.
Online referral marketing, using digital marketing as a platform, is the internet based approach to traditional referral marketing. By tracking customer behavior online through the use of web browser cookies and similar technology, online referral marketing can potentially provide a higher degree of accountability than offline models.
