• Excitement from discovery (when no rewards given)

• FOMO (Fear of missing out)
Rewards are great, but if you can convince them to SPEAK IT OUT is even better

The Viral Coefficient
(aka k-factor) .
K-factor is the total number of registrations
per unique inviting user.
Say that, on average, 1 in 5 of our users will successfully recruit a new
user in their first month. In other words, our viral factor is 1/5 = 0.2, and
our initial 5,000 users will recruit another 5,000 * 0.2 = 1,000 users in
month 1.

For a consumer internet product, a
sustainable viral factor of 0.15 to 0.25 is
good, 0.4 is great, and around 0.7 is
outstanding .
