    What Are Recommender Systems in eCommerce? 

    A recommender system is a type of information filtering system that predicts and recommends items that a user may be interested in based on their historical behavior, preferences, and characteristics. It analyzes patterns and relationships in user data, such as purchase history, browsing behavior, and ratings, to make personalized recommendations. Recommender systems are commonly used in eCommerce platforms, online streaming services, social media, and search engines to provide personalized suggestions and improve user engagement. 

    Recommender systems are commonly used by eCommerce platforms and websites to personalize the shopping experience for their users. By analyzing user data such as purchase history, search queries, and browsing behavior, recommender systems can suggest products that the user is likely to be interested in, and improve the chances of a successful sale.

    How do Recommender Systems in eCommerce Boost Sales? 

    There are many advantages to using a recommender system. 

    Enhancing Sales 

    Recommender systems can enhance sales and increase the average order value in several ways:

    • By providing personalized recommendations to users, the system can increase the chances of a successful sale. When users see products that are tailored to their preferences and interests, they are more likely to make a purchase. This can lead to increased conversion rates and higher revenue for the eCommerce platform.
    • Recommender systems can help with cross-selling and upselling. By recommending products that are related to the ones the user is currently viewing or have previously purchased, the system can encourage users to buy additional items they may not have considered otherwise. This can increase the average order value and revenue per customer.
    • They can help reduce the time and effort required for users to find relevant products. By analyzing vast amounts of data and presenting users with personalized recommendations, the system can save users the effort of searching for products themselves, making the shopping experience more convenient and enjoyable.

    Customizing Content

    Recommender systems help websites deliver relevant, customized content by analyzing user data such as search queries, browsing history, and demographics to make personalized recommendations. 

    By using machine learning algorithms and data mining techniques, a recommender system can identify patterns and relationships in user behavior and make predictions about what content a user is likely to be interested in. This can help websites deliver targeted content that is more likely to engage users and keep them on the site. Additionally, by tailoring content to each individual user, recommender systems can improve the overall user experience and increase user satisfaction.

    Keeping Everything On-Brand

    A recommendation engine can help deliver a consistent brand experience by providing personalized recommendations based on the user’s browsing and shopping history, and other data. By presenting a cohesive and tailored set of products or content to the user, the recommendation engine can help reinforce the brand’s messaging and image. 

    Additionally, the system can identify and exclude items that are inconsistent with the brand’s values, ensuring that the user is only presented with products or content that align with the brand’s message and image.

    Providing Information for Buyers

    Recommender systems can provide reports to guide consumers’ decision-making. For example, some recommender systems can display detailed product information, ratings, reviews, and comparison charts to help users make informed purchasing decisions. 

    Recommender systems can also provide insights and feedback based on user behavior, such as which products are frequently viewed or purchased together, and which products have the highest ratings or reviews. This information can be used to guide the user towards products that are more likely to meet their needs and preferences. 

    How Recommender Systems in eCommerce Work 

    eCommerce recommender systems work by analyzing user behavior data and making predictions about the items the user is likely to be interested in. There are different types of algorithms used in recommender systems, including collaborative filtering, content-based filtering, and hybrid methods that combine both approaches:

    • Collaborative filtering algorithms analyze implicit and explicit user data to make recommendations. Implicit data refers to the user’s behavior data, such as purchase history, search queries, and clickstream data. Explicit data, on the other hand, refers to user ratings, reviews, and other explicit feedback. Collaborative filtering works by finding patterns and relationships between users and their interactions with products, and using that information to make recommendations. One approach is to identify users with similar behavior patterns, and recommend items that are popular among those users.
    • Content-based filtering algorithms, on the other hand, analyze the characteristics of the items and the user’s behavior data to make recommendations. This approach involves analyzing the attributes of the items, such as product descriptions, tags, and other metadata, and matching them to the user’s preferences. The system can also analyze the user’s behavior data to identify patterns in the user’s interests and preferences, and use that information to make recommendations.

    In practice, eCommerce recommender systems can use a combination of these approaches and data sources to make personalized recommendations to users. For example, a system might use collaborative filtering to identify users with similar interests and content-based filtering to match items to a user’s preferences.

    To gain insights, recommender systems can use multiple sources of information, focusing on product information, user profiles, and other user behavior data. They can also use information from external sources, such as social media activity, to gain additional insights into user preferences and behavior.

    4 Examples of Recommender Systems in eCommerce 

    Amazon

    Amazon.com’s book section has several features that use recommender systems to help users discover new books and authors based on their preferences and behavior:

     

    • “Customers who bought this item also bought” is a collaborative filtering algorithm that analyzes implicit user data, such as purchase history, to recommend books that are frequently purchased together. This feature helps users discover related titles and authors that they may be interested in based on the behavior of other users with similar interests.
    • “Eyes” is a content-based filtering algorithm that analyzes the user’s browsing behavior and recommends books based on the user’s past viewing history. This feature uses implicit data to identify the books that the user has looked at in the past, and then matches those books with similar titles, authors, or themes.
    • “Book matcher” is a hybrid approach that combines collaborative and content-based filtering. This feature asks users to rate books they have previously read, and then uses those ratings to generate personalized recommendations based on both implicit and explicit user data. The system uses collaborative filtering to identify users with similar interests, and content-based filtering to match those users with books that are likely to appeal to their individual tastes and preferences. 

    eBay

    eBay’s feedback profile feature is a system that allows buyers and sellers to rate and provide feedback on their transaction experience. After a transaction is complete, both parties have the opportunity to rate each other and provide comments on the transaction. These ratings and comments are then displayed on the user’s feedback profile, which is publicly available to all eBay users. 

    The feedback profile feature is designed to help establish trust and accountability between buyers and sellers, and to provide information to other users about the reliability and quality of the transaction experience. It is a key component of eBay’s user rating and feedback system, which is intended to ensure a safe and successful transaction experience for all users.

    Netflix

    Netflix’s recommender system is a content-based filtering algorithm that analyzes user viewing history and feedback to make personalized recommendations. The system uses implicit data such as viewing history, search queries, and ratings to identify patterns and relationships between users and the content they engage with. The system then uses this data to generate personalized recommendations for each user. 

    In addition, Netflix uses a technique called recommendation clusters to group similar items into categories, such as action movies, romantic comedies, or science fiction series. These clusters help to further refine recommendations by identifying patterns in user behavior and content preferences, and grouping similar items together for easier browsing and discovery.

    Levi’s

    The style finder feature on the Levi’s clothing website is a tool that helps users find the perfect pair of jeans based on their style preferences. Users are first prompted to choose their gender, and then select their preferred fit, rise, and leg opening. The system then uses a 7-point scale to gauge the user’s preference for different design details. Users can rate each category on a scale from “not at all” to “very much,” and the system generates personalized recommendations based on their preferences.
