Netflix is one of the most popular streaming services in the world, offering users access to a vast library of movies, TV shows, and original content.
But how does Netflix decide what to recommend to you? How does it know what you’ll like and keep track of what you’ve watched?
In this article, we’ll take a closer look at how Netflix’s recommendation system works.
The Basics of Netflix’s Recommendation System
Netflix’s recommendation system is based on a complex algorithm that takes into account a variety of factors.
These factors include your viewing history, your ratings, your search history, and even the time of day.
The algorithm uses this information to predict what you’ll enjoy watching next and offers personalized recommendations based on that prediction.
One of the key features of Netflix’s recommendation system is its use of machine learning. This means that the algorithm is constantly learning and evolving based on new data.
Every time you watch something, rate something, or search for something, the algorithm gets a little bit smarter and better at predicting what you’ll like.
How Netflix Determines What to Recommend
There are a few different methods that Netflix uses to determine what to recommend to you:
- Collaborative Filtering: This is the most common method that Netflix uses. It looks at what you’ve watched and rated, and compares that to what other users with similar viewing habits have watched and rated. Based on that comparison, it predicts what you’ll like.
- Content-Based Filtering: This method looks at the characteristics of the movies and TV shows you’ve watched and rated, such as genre, cast, and director. It then recommends other content with similar characteristics.
- Personalized Rankings: Netflix also uses a personalized ranking system to determine what to recommend. It assigns each user a unique set of rankings for each movie and TV show in its library, based on how likely that user is to enjoy that content. This ranking system is then used to offer personalized recommendations.
How Netflix Keeps Track of What You’ve Watched
In order to make accurate recommendations, Netflix needs to keep track of what you’ve watched. It does this in a few different ways:
- Viewing History: Netflix keeps a record of everything you’ve watched on its platform. This includes movies, TV shows, and even individual episodes.
- Ratings: When you rate a movie or TV show on Netflix, it uses that rating to refine its recommendations for you.
- Search History: Netflix also keeps track of what you’ve searched for on its platform. This can help it make recommendations based on your interests.
- Playlists: Finally, Netflix also keeps track of any playlists you’ve created. This can help it make recommendations based on your overall interests and viewing habits.

By using a combination of collaborative filtering, content-based filtering, and personalized rankings, Netflix is able to offer personalized recommendations that keep users coming back for more.
And with its use of machine learning and constant data analysis, the recommendation system is always getting smarter and better at predicting what users will enjoy watching next.
