Viral marketing is a strategy that encourages individuals to share a marketing message with others, rapidly spreading the message like a virus. This often occurs through social media, email, or word-of-mouth, and can lead to exponential growth in the message’s reach. Viral marketing campaigns typically involve content that is highly engaging, entertaining, or emotionally resonant, prompting people to share it with their networks. While the success of viral marketing can be difficult to predict, it has the potential to generate massive brand awareness, increase traffic, and create a buzz around a product or service.
