How recommendation engines work

Recommendation engines (or recommender systems) is very important feature for online stores. It helps users to get the products that better meet their needs. On the other hands it increases revenue of the merchant (or service provider) by up to 25% according some estimates. So recommendation engine is a good example of win-win IT solution – good for both consumers and businesses.

  • Content-based, based on similarities between the pieces of the content
  • Collaborative, based on the preferences of other users
