Undercover marketing, also known as stealth marketing or buzz marketing, is a form of advertising that involves promoting a product or service in a subtle and covert manner. This type of marketing relies on creating a sense of intrigue and curiosity among consumers, often through the use of unconventional tactics such as product placement, viral campaigns, or influencer endorsements. The goal of undercover marketing is to create a buzz and generate interest in a product without overtly appearing as an advertisement. It is a strategic and often sneaky approach to marketing that aims to reach consumers in a more organic and authentic way. However, it has also been criticized for being deceptive and manipulative.
