Word of mouth marketing (WOMM) involves creating positive conversations about brands and products to gain new customers. It is based on customer satisfaction and two-way communication. The goal is to identify brand advocates and give customers tools to share their experiences. Marketers can amplify word of mouth by launching campaigns, but organic word of mouth from satisfied customers is the most effective. Common WOMM strategies include viral marketing, buzz marketing, and influencer marketing. Marketers should provide value to customers and make it easy for positive experiences to be shared.
