A Recommendation engine or recommendation system is an information filtering tool that provides the most relevant suggestions regarding products or services to various customers. A recommendation engine uses machine learning algorithms to collect and analyze user activities such as their preferences, search history, and others.
Nowadays most digital products or service providers use recommendation engines in their platforms to come up with the most relevant content for different users. It is used in most of the leading digital stores starting from Netflix, Spotify to online shopping stores like Amazon. A good recommendation system not only enhances the users’ experience but also helps in scaling up your B2B SaaS business.
Recommendation engine works in three different ways-
- Collaborative Filtering
In the collaborative filtering method, a recommendation engine can predict a user’s preferences by collecting the data regarding the preferences of a large number of users. A recommendation engine based on collaborative filtering has a simple yet effective approach- people often get the most helpful recommendation from other people having a similar taste. The workflow of a recommendation engine equipped with a collaborative filtering method is as follows-
- Generally, a customer conveys his or her preferences by rating the products or services such as music, videos, books, and others. A recommendation engine takes these ratings as representations of the user’s interest.
- The recommendation system then matches a single user’s rating against other users’ ratings to find the people with the most similar tastes and recommend accordingly.
- Collaborative filtering generally works with a large set of data to provide the most relevant and precise recommendation to different users.
- Content-based Filtering
Content-based filtering enables a recommendation engine to suggest the most accurate and relevant content to users based on their preferences for features of products or services. A recommendation engine with content-based filtering works on-
- Description or details of a digital product or service
- Profile of the user’s preferences which includes the history of the user preferences
A content-based recommendation engine often includes an opinion-based recommendation system that analyzes the information related to the user’s reviews, comments, and feedback to offer more appropriate recommendations.
- Hybrid of the Two
A hybrid filtering comprises both the above filtering methods. A recommendation engine with hybrid filtering is capable of recommending customers on the basis of both their preferences and the preferences of the more significant number of customers.
