Use additional entries and campaign actions to reward the behavior that matters to your campaign.
The actions are defined by the campaign. The reward structure is controlled by the campaign owner. Nothing is locked to a fixed template.
A referral link earns a share of that person's audience. A newsletter subscription earns a direct line of communication. A completed form earns the exact data your team needs. Gamification turns a one-time entry into a series of small, valuable actions, each one worth rewarding on its own terms.
Reward the actions that grow your audience: referrals, subscriptions, shares, community joins.
Turn promotion into competition with a leaderboard that ranks sources by the participation they generate.
