Viral marketing is a marketing strategy that involves creating content that is intended to be shared quickly and widely among a target audience. This type of marketing relies on social networks and word-of-mouth to spread messages and encourage engagement with a brand or product. Viral marketing campaigns often leverage social media, video sharing platforms, and other online channels to reach a large audience in a short amount of time. The goal of viral marketing is to create buzz and generate interest in a product or brand through the organic sharing of content by consumers.
