A Complete Guide to Product Recommendations on WhatsApp

As product sales have moved online, product recommendation engines have surfaced to leverage the huge volumes of user data to serve customers.

Conventional businesses typically depend on customers to visit the retail outlet to discover their product inclinations, but a tech-powered purchasing ecosystem banks on the potential of data, analytics, and customer-specific personalization.

Consumers now demand brands to realize their tastes and purchasing preferences in advance. That's why integrating product recommendation systems in the sales model has gained traction over the years.

Statistics suggest that visitors who browse product recommendations have 4.5 times more chances to add these products to their cart and are 4.5 times more likely to finish the purchase.

As a result, numerous multinational brands are already offering tailored product recommendations to create relevant customer experiences for increasing conversion rates.

What are Product Recommendations?

Fundamentally, product recommendations are just products that a business suggests to consumers. It is, at its core, a filtering mechanism that anticipates and promotes products that your customers are likely to purchase.

Product recommendations can be provided in several ways, such as by an experienced shop assistant, in a promotion email, on a product page of an online website, or using instant messaging platforms like WhatsApp to deliver personalized messages to entice customers.

With the eCommerce boom, as product sales have moved online, product recommendation engines have surfaced to leverage the huge volumes of user data to serve customers with personalized product recommendations.

A product recommendation engine is a robust solution that produces tailored recommendations based on user analytics, machine learning algorithms, and consumer-specific data, including:

✅Product reviews and testimonials

✅Product page view frequency

✅Purchase and return history

✅Shopping cart events

✅Click-through and search activity

Three Prominent Types of Product Recommendation Engines

1. Collaborative Filtering

This filtering strategy gathers and analyzes users' purchasing behavior and preferences data and projects which products they would like based on their buying patterns in relation to other users.

2. Content-Based Filtering

These filtering engines rely on a product's description and a customer's profile of top choices. In this recommendation engine, algorithms attempt to offer products similar to those a customer has previously liked.

3. Hybrid-Recommendation System

This engine integrates collaborative-based and content-based techniques, generating a recommended products list based on data from customers with similar interests and an individual customer's previous preferences.

How Does a Product Recommendation Engine Work?

An effective and powerful product recommendation engine goes through four stages of data processing-

1. Data Collection

It is inclusive of both explicit and implicit data. The explicit data refers to the details offered by customers, such as product reviews and ratings. In contrast, implicit data includes characteristics, such as order and return activity, cart transactions, product page views, click-through rate, and keyword search logs.

2. Storing Data

Humongous volumes of user data are fed into a product recommendation engine as the data quality and quantity input into the models and algorithms directly influence the performance and reliability of the recommendation engine. The data type and format utilized can assist you in deciding what sort of storage to use.

3. Customer Data Analytics

The next step is to refine the data using numerous analytical methodologies. You can analyze the gathered information in multiple ways, including-

✅Real-time systems

✅Near real-time analytics

✅Bath analysis

4. Data Filtering

The last phase is to select a screening mechanism. You can pick the most suitable recommendation system from the three options for filtering: collaborative, content-based, or hybrid.

4 Real-World Examples of How Top Brands Leverage Recommendation Engines

1. Amazon

To achieve the personalization of the online marketplace for each consumer, Amazon employs item-to-item collaborative filtering recommendation algorithms as a targeted advertising strategy throughout the platform.

When a user clicks the "your recommendations" link, he is taken to another product page where he can sort recommendations by product relevance, category, reviews, and past orders. The buyer could also discover why a specific product got recommended.

According to statistics, Amazon's recommendation engine generates 35% of its revenue.

2. Best Buy

The recommendation system of the consumer electronics retailer is centered on query and keyword search and clicking metrics. Best Buy has leveraged user data to anticipate what products buyers may be willing to engage with. The query-based and product-to-product approach generates clustered models, which enable the business to provide product recommendations to visitors.

The algorithm predicts which product a shopper is inclined toward based on their platform activity and buying history.


3. Spotify

Spotify's renowned Discover Weekly playlist is one of the company's most prominent use cases of ML-powered recommendation engines. This application refreshes customized playlists weekly so that people don't miss freshly released content by their favorite artists.

The platform uses three recommendation models -

  • Collaborative filtering- Sorting music by analyzing individuals' past listening data and comparing it with the listening history of other users.
  • NLP- Scraping online for gathering data on certain artists and music, then assigning each to a dynamic list of top expressions that constantly changes and is weighed by relevance. The algorithm then evaluates if two work samples of the artists depict some similarity.
  • Audio analytics- The system analyzes each person's audio file's attributes, such as volume, tempo, tone, etc., and offers content suggestions accordingly.

4. YouTube

The online video streaming platform employs recommendation engines to provide personalized content recommendations, allowing users to hop on to relevant videos seamlessly.

The content recommendations get updated regularly according to changing user content consumption preferences, tastes, and browsing activity on the platform while also spotlighting the huge set of alternative content.

The content recommendation engine on YouTube is powered by deep learning algorithms and composed of two neural networks. The first one analyzes and aggregates data on users' viewing patterns and leverages collaborative filtering to filter user-relevant content among several videos. The second one ranks the filtered content pieces to offer useful suggestions.
