Why product recommendations matter for your Shopify store. Product recommendations are one of the most effective ways to increase average order value (AOV) and drive repeat purchases. When a customer sees a complementary item - like a phone case with a screen protector or a dress with matching shoes - they are far more likely to add it to their cart. Studies show that personalized recommendations can boost AOV by 20-35% and account for up to 30% of ecommerce revenue. But not all recommendation engines are created equal. The best Shopify app for product recommendations uses machine learning to analyze your store's order history, identify product pairs that are frequently bought together, and surface those suggestions at the right moment - on product pages, in the cart, during checkout, and even in post-purchase emails. Without ML, you are stuck with manual rules or generic suggestions that miss the mark. Personalized product recommendations can increase average order value by 20-35% and account for up to 30% of ecommerce revenue.
