1. Emotion: People are compulsive when it comes to sharing emotional stories with many details. These stories, both good and bad, are irresistible to re tale to others, and thus the idea spreads.
2. Public Service: In order for viral marketing to really work, you must have your audience wanting to interact with you. If they like your idea or product, they will tell everyone they know about it for free.
3. Trigger: This is what keeps your audience talking about you and your company. It is a steady reminder of what your audience loved about your company to begin with and begins a need for them to tell others.
