What is Virality
Virality is the phenomenon where content or products self‑propagate through user sharing at a rate that exceeds acquisition via paid or owned channels, often measured by the viral coefficient.
Key points
- Viral coefficient (K): Average invites sent × conversion rate; K > 1 indicates growth.
- K‑factor lever: Increase invites per user or invite‑to‑signup rate.
- Network effect: More users create more value, fueling sharing loop.
- Trigger types: Utility (Dropbox), emotion (videos), incentives (referral credits).
- Decay: Virality fades; sustain with new hooks.
Pro tips
- Make share action frictionless (one‑tap).
- Align incentives with core value, not gimmicks.
- Track K weekly; small lifts compound exponentially.
