Cross-selling is the act of pushing other products related to the primary product on offer. Statistically, cross-sales attributes to 30% of e-commerce websites’ sales, which means using this technique can dramatically increase your online store sales. Cross-selling makes customers’ work easier if they are looking for alternative products. They won’t have to scavenge your e-commerce platforms to find those alternatives. Your sales promotion strategy should include cross-selling, which means listing out alternative products from the main promotion product. Case in point: If your e-commerce website deals with Smartphones, your promotion should include Smartphone accessories such as charging cables, phone cases, and Bluetooth earbuds.
