The product recommendation software finds the best suitable product based on individual characteristics. Today’s learning will discuss eCommerce product recommendation systems in detail.

What is Product Recommendation Systems?

Recommendation systems or recommendation engine is a subclass of mission learning. Similarly, machine learning is also a subset of artificial intelligence. The recommendation software predicts the most suitable product based on a rating of products and users. Based on the ranking of prediction, it is back to the user.

A product recommendation engine tracks all users’ activities like browsing history, purchase history, search pattern, frequency of transaction, demographic and age category, etc. After analyzing all of that data, it automatically recommends products to the user.

The recommendation system deals with large volumes of data. With the help of data science, artificial intelligence product recommendation systems recommend the most suitable items to the specific user.

Similarly, the business organization can sell goods faster, increasing their turnover and preserving data for future offerings.

Benefits of recommendation system

All the big organizations like Google, Instagram, Spotify, Netflix, Amazon, and Reddit use recondition engines to increase engagement with users. For example, Amazon recommends its products based on the collected data from the user. Spotify recommends music in the same way. So there is a massive benefit to using a product recommendation tool. Here is some help for you.

Breath of Data Depth of Data

Businesses serve only a handful of customers. The automated recommendation is not useful. Customers need direct conversation and interaction. For example, using sales girls.

Having a single data point for each customer is not helpful. They purchase online. Moreover, they expect online recommendations.

I want to classify the industries that can use product recommendation engines best on this framework.

1. Recommendation engine eCommerce business

Most of the recommendation systems are used in an eCommerce business. There are three types of e-commerce business to business, business to customer, and customer to customer. We can see business-to-customer eCommerce business uses recommendation tools. Amazon, eBay, Walmart, and Flipkart are the best example.

4. Banking sector

Financial data is essential for decision-making. The SME sector always needs financial data. Based on the economic behavior and transaction history, Bank can recommend their customers for father loans.

5. Telecom sector

Telecom securities are similar to banking because it has millions of customers. Based on the geographical and is group, the requirement is different. Someone may need a small data plan, and someone needs free Talktime. Recommendation systems can improve customer service for maximum sales.

6. Utilities

Tips before choosing a product recommendation engine

Before implementing a recommendation engine for your business, you need to know the actual requirement of your eCommerce platform. Hair solid backlog of valuable customer information is a must. Based on some other criteria, this engine can become fully optimized.

What to the procedure before offering a recommendation strategy?

The ultimate goal of a business organization is to provide the right product to the right person. This strategy will create a good user experience and increase the possibility of cells. This recommendation system follows several strategies and rules. Here are some procedures that you can follow:

1. Focus on algorithm

The filtering algorithm is essential to recommend any product to your customer. Many filtering algorithms like collaborative filtering, content-based filtering, and hybrid recommendation.

Out of the three hybrid algorithms, it is the most suitable. It combines all the rules and data and suggests the best product for your customer.

2. A/B testing

A/B testing is comparing several engines to find the best suitable product. There are a lot of comparing tools for A/B testing. However, VWO optimized, and Google optimized the popular testing tools.

3. Study your case

Own business case study is critical. Track your recommendation engine to find out the responses from customers. You have to ensure your return on investment and marketing matrix. If it does not get any testimonials from the users, you can switch to other options.

4. Customer support

Customer support and after-sales service are essential for users and businesses because of many technical issues, such as software errors like wrong recommendations and unresponsiveness. For an online eCommerce business, 24/7 support is vital. 

Types of recommendation system

The recommendation engine is classified based on various criteria and algorithms. Here are some types of this system:

1. Popularity based system

The popularity system works based on popular topics and recent trends. Movies, songs, and videos are recommended based on popularity algorithms.

I can site examples like new year sales, geographical festival sales, YouTube movie recommendations, and Netflix episode suggestions.


  • You do not need any historical data for the popularity algorithm.
  • Day one business also can recommend products.


  • The popularity algorithm system is not personalized based on the user.
  • It recommends products based on the liking of other users.


  • The trending videos on YouTube.
  • Google News feed on Chrome browser.

2. Classified model

The classified model uses the feature of products as well as users. It predicts whether the user will choose the product or not. The outcome will be 0 or 1. 0 represents the user will not select the product. When a user would like it, the output will be 1. 


  • Classified models ensure more customization.


  • Collecting data is a rigorous process. Without a high volume of information, correct recommendations will be complex.
  • Classification of the data is also difficult.
  • You may face flexibility issues.

3. Content-based recommendation engine

Content-based recommendation works based on the algorithm of similarity. When you watch a movie of adventure, the system automatically recommends another adventure movie.

Content best recommendation system uses the Euclidean distance model. The system checks the similarity of different products and computes the distance between them. Based on the different scenarios, it finds a parallel. Moreover, it uses a different matrix. The matrix mainly follows Cosine similarly and Jaccard similarly.


  • There is no requirement for users’ much data.
  • We only need the item data to recommend users.
  • It is not dependent on the user’s data. You can recommend any new user if they do not have any profile.
  • It’s free from the cold start problem.


  • You need a good volume of item data.
  • The features may not be available for finding similarities.

4. Collaborative filtering

The eCommerce websites and online movie websites use a collaborative filtering recommendation system. This smart recommendation engine checks the taste of similar users and searches for the similarities of products. The system is more efficient if we have a large volume of data. 


  • Collaborate filtering is a smarter algorithm than any other recommendation algorithm.
  • The chances of selling conversation become higher.


  • The system requires enough users to find the match.
  • Due to sparsity problems, there may arise the issue of recommending items.
  • Knowledge-based system

When the system needs a complete decision, you can use a knowledge-based system. It requires knowledge regarding subject data. It has a set of rules or guidelines.

When your customer buys any camera, they need a camera bag. Your system may offer 5 to 10% discount on the camera bag. The rules may be based on diversity, privacy, serendipity, trust, long tail, and user demographic.

5. K Fold Cross-Validation

You can use the K Fold cross variation model if you need more accuracy. This algorithm makes a model predict the demand of users based on a set of features. It trains the recommendation system. This system is very costly.

6. Hybrid recommendation system

The hybrid recommendation engine combines both collaborative filtering and content best filtering method. It can overcome the limitation of the above two algorithms.
