# Review and Earn According to a [report](https://www.dixa.com/blog/3-important-statistics-that-show-how-reviews-influence-consumers/), 93% of customers read reviews before purchasing, and on average, reviews produce an 18% growth in sales. So, customer reviews play a significant role in product sales. #### **Challenges in Existing Review Model** A customer can write a positive review or a negative review. If a customer has a negative experience with a product, they express their dissatisfaction by writing a negative review. The customers who have a good experience with a product have no/little motivation to write a positive review. Some companies offer coupons or extra discounts for writing a positive review. However, writing reviews for incentives is immoral and unfair. #### **Reward Model as a Solution** DonBangSeok encourages customers to write a review by offering IDC. If a customer writes a review within one week/two weeks after the purchase, then the reviewer can earn 5%/1% of the brand token amount worth of IDC as a reward. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
