Content Marketing is the marketing involves the creation and sharing of media, publishing, and distribution of content in order to inspire prospects, gain customer loyalty, and acquire customers. Content marketing is not about selling, rather on simply communicating with customers and prospects. It is a strategic marketing approach focused on creating and distributing valuable, relevant, and consistent content to attract and retain a clearly-defined audience — and, ultimately, to drive profitable customer action. The essence of this content strategy is the belief that if businesses deliver consistent, ongoing valuable information to buyers, they ultimately reward them with their business and loyalty.
