What Is A Recommendation Engine?
A product recommendation engine is essentially a solution that allows marketers to offer their customers relevant product recommendations in real time. As powerful data filtering tools, recommendation systems use algorithms and data analysis techniques to recommend the most relevant product/items to a particular user. The main aim of any recommendation engine is to stimulate demand and actively engage users. Primarily a component of an eCommerce personalization strategy, recommendation engines dynamically populate various products onto websites, apps, or emails, thus enhancing the customer experience. These kinds of varied and omnichannel recommendations are made based on multiple data points such as customer preferences, past transaction history, attributes, or situational context.
Here are the top 10 recommendation engines commonly used in various industries:
