Product Recommendations have become a must-have for eCommerce businesses to deliver the best experience to their customers. In the digital age where users have access to the best customer experiences that help them build loyalty towards their favourite brands, not having a personalized recommendation system might be putting retailers at a disadvantage. 

Most eCommerce websites leverage data and Artificial Intelligence to deliver a personalized experience to their customers by giving them relevant product recommendations, increasing their engagement, conversions and revenue. Listed below are some real-world examples of success with product recommendations.

What are Product Recommendations?

Product Recommendations is an eCommerce personalization strategy that aims to populate a customer’s webpage with relevant products based on pre-existing data such as browsing history, customer attributes and product information. 

Product recommendations influence a customer’s choices and increase revenue, engagement and conversions for eCommerce retailers at scale. Ecommerce recommendations particularly come into play when a retailer has a diverse inventory of products.

How do Product Recommendations work?

A product recommendations system takes into account specific information about the users and predicts whether a specific product would be suited to their needs or not. Typically, a rating is used to determine the likelihood of the user picking a product based on the existing data provided to the recommendation engine.

A good product recommendation engine can make informed decisions about the users with the data provided even before the user interacts with the system. A product recommendation system usually comprises a combined mechanism of specialized algorithms and techniques that can score through large volumes of data(product catalogues, inventory, etc).
A product recommendation system processes data in four steps, as follows:

  1. Data Collection – The product recommendation system collects data from the users – like product ratings and reviews, comments, etc(Explicit data) or page views, order and return history(implicit data)
  2. Data Storage – The product recommendation system then stores the data and sorts it out in a database. This helps with the next step, which is analysis.
  3. Data Analysis – Different analysis methods are run on the data that was collected and the product recommendation engine finds products with similar user engagement
  4. Data Filtering – The product recommendation system then filters the relevant information based on the specific algorithms to provide recommendations to the user.

Here are some Product Recommendations examples:

  • Bundling – Recommending products that are frequently brought together as a package to customers is called ‘Bundling’. Bundling helps you increase the value of your customer’s cart.

    For example – If they are buying a new smartphone, recommend a compatible case and other accessories.
  • Upselling – Recommending higher-priced products based on similarity to tempt your customers to upgrade their purchase can help increase revenue-per-transaction. Upselling particularly works very well with high-intent browsers.
  • Trending Products – Featuring products that are popular and gaining traction helps to maintain relevancy in the eyes of the customer. Popular products that are moving fast also lead to higher traffic.

    For example, many eCommerce sites listed COVID-19 Essentials such as masks and sanitisers on their homepages which significantly contributed to their traffic, engagement and sales.
