Rakuten is a cash back rewards platform that allows members to earn money back on their purchases by shopping through their website at over 3,500 partner stores. The company earns commissions from merchants when customers visit their shops via Rakuten's links, and passes a portion of these commissions back to members as cash back rewards. Rakuten works by having members shop as usual through their platform, then receive cash back on those purchases. They are best suited for referrals from e-commerce businesses, retailers, and discount-focused services that want to connect customers with ways to save money on their shopping.
