Viral marketing in the retail industry involves the strategic creation and promotion of content with the goal of it spreading rapidly and extensively among consumers. This form of marketing relies on social networks, word-of-mouth, and online sharing to increase brand visibility and reach a wide audience quickly. Viral marketing campaigns often leverage compelling and shareable content, such as videos, memes, or interactive experiences, to encourage users to share the content with their networks. The viral nature of these campaigns can lead to increased brand awareness, customer engagement, and ultimately, a positive impact on sales for retailers.
