What is Product Recommendation?
Product recommendation is a marketing and sales technique that uses customer data, purchase history, and behavioral patterns to suggest relevant products that customers are likely to buy. This personalized approach enhances the shopping experience by presenting targeted product suggestions at optimal moments throughout the customer journey.
Why is Product Recommendation Important?
Product recommendation is essential for increasing sales revenue and improving customer satisfaction in retail and eCommerce environments. Effective recommendations can boost average order value by 10-30% and increase conversion rates significantly. By showing customers relevant products they might not have discovered otherwise, businesses enhance the shopping experience, reduce decision fatigue, and build stronger customer relationships through personalized service.
Example of Product Recommendation
An electronics store uses product recommendations when a customer purchases a new laptop. The POS system automatically suggests compatible accessories like a wireless mouse, laptop case, and external hard drive based on previous customer purchase patterns. The sales associate mentions these items, and the customer adds a $50 mouse and $30 case to their purchase, increasing the transaction value by $80.
