The Viral Loop
The Math behind ViralityKey variables:Custs(0)	The initial set of customersi			The number of invites sent outconv%		The percentage of invites that				convert into customers
The Viral CoefficientK		The Viral CoefficientK = no of invites  x  The conversion %    (i x conv%)Turns out to be a very important variable. It equals the number of new customers that each customer is able to successfully invite.
An ExampleCusts(0)		= 5i 			= 10conv% 		= 20%K			= 2
The FormulaNew custs added in this cycle =New custs added in the previous cycle    x     KAssumes that customers only send out invites once, and not continuously in every later cycleTo calculate the number of customers at any particular cycle (c):Custs(c) = Custs(c-1) + NewCusts(c)

Lessons Learned Optimizing for Virality
Lessons LearnedApply my “Unblock your Sales Funnel” principles to the viral loop steps
GET INSIDE YOUR CUSTOMER’S HEADCONCERNSHate being sold to
Find it offensive to give name and email
Don’t want to get spam sales emails
Worried that email address will be given to other marketersUNDERSTAND WHAT MOTIVATES THEMCONCERNSMOTIVATIONSWant to solve my problem

Meeting other people like me that have insights to shareCREATE A SOLUTION THAT ENTICES THEM AND ADDRESS THEIR CONCERNSCONCERNSENTICE & ADDRESS CONCERNSCustomer testimonials address vendor risk
Free trials address product viability and fit concerns
Lowest price guaranteesExample: Groupon
Example: Living Social
Another strategyOffer a reward both to the user and to their friendOvercomes the feeling of being sleazyCan lead to much higher success rates
Lessons LearnedMaximize the number of invites they send outLeverage tools that provide easy reach to their friends:TwitterFacebook: post to their News StreamLinkedInAutomate access to their address bookWorks well for GMail, and other on-line address booksEtc.
Lessons LearnedLook for ways to automate the whole invitation processNo thinking requiredNo work required
