FOMO: (Fear Of Missing Out)
Originally, FOMO is a psychological concept which represents the feeling that others are basically living a better life than you, and that you could be doing something better. Social media in particular is a real problem for some people as it intensifies this feeling. As a result, marketers cleverly started using “FOMO marketing” in order to encourage people to jump on an opportunity before it’s too late. FOMO marketing techniques include offers with a deadline, limited editions products, showing stock levels.
