A promotional code, also known as a coupon code or discount code, is an alphanumeric string that customers can enter during the checkout process to receive a discount or other benefit, such as free shipping or gift-wrapping. Promotional codes are typically associated with an overarching promotional marketing strategy and can apply to individual products or an entire order. They can be a percentage or a specific dollar amount off the purchase price. Promotional codes are an effective way to incentivize customers to make a purchase, adding value for the customer and building loyalty for both new and returning customers. Different types of promotional codes include percentage-based discounts, fixed amount discounts, and reward codes for loyal customers. Promotional codes can also be used to track marketing efforts and see which platforms are generating the most traffic or leading to conversions.
