The best strategies for referral bonuses include offering tiered rewards, providing double-sided incentives, and ensuring clear communication. Tiered rewards motivate users to refer more by increasing bonuses with each referral (e.g., ₹100 for the first, ₹200 for the second). Double-sided incentives reward both the referrer and the referee, making participation more appealing. Additionally, use limited-time offers to create urgency and track performance to optimize results. Make sure the referral process is simple, mobile-friendly, and promoted across email, social media, and in-app notifications for maximum reach.
