Reward your customers with any point system, currency, gift or membership benefit.
Build referral rewards that devalue over time and give advocates the incentive to convince quicker.
Relay important brand updates and give rewards after each step of your new customer's on-boarding.
Create ambassadors of your affiliates, employees and influencers. Appeal to these groups with KPI-based or staggered rewards, and build a stronger base of dedicated users.
Get your advocates to be more hands-on with their referrals. Set rewards that increase in value for each completed stage of the onboarding with their friends or for each referral they make.
Spend less on referrals by incentivizing any success criteria you like. Reduce credit value over time to show the clock is ticking or only reward advocates after a period of time is up.
