9 Best Product Recommendation Engines to Boost Sales in 2024

A product recommendation engine tracks your site visitors’ activities and automatically recommends products they’re probably interested in. This is a powerful marketing mechanism because it is designed to offer each customer a unique, personalized experience.

Over the years, personalization has become the new anthem in the world of marketing. This has become so paramount that 83% of customers are happy to share their data if it leads to improved personalized experiences.

eCommerce giants like Amazon, Target, L’Oreal, and Alibaba leverage the power of product recommendation engines to save marketing costs and generate extra revenue.

If your business has a large team of skilled developers, you can develop your recommender system in-house. But for smaller companies, there are several vendors that offer this solution out of the box.

Today’s guide will reveal 8 of the best product recommendation engines used by the most successful eCom businesses in 2022. You will also learn a few tips to help you make a choice that best suits your business needs.

Let’s proceed.

Before you choose a Product Recommendation Engine

Before you finally settle on which recommendation engine you would adopt for your business, there are a few things you’d need to do.

First, ensure that your store has a solid backlog of valuable customer information and can generate high-quality data regularly. This will give your recommender system what to work with right off the bat, helping it optimize faster. You could start with a clean slate and scale up on the way. However, it will take more time for your recommendation engine to fully optimize.

Also, it is important to have a data centralization solution to get the best out of your product recommendation system. 

Product recommendation strategies usually involve multiple channels, from product pages to emails and social media ads. Each channel generates unique streams of customer data. Manually tracking and analyzing these data streams from their individual sources can be messy and time-consuming, especially for scaling businesses.

However, a good data management system will pull these data streams from their respective sources, consolidate them into one destination, and offer marketers a clean, unified view of their customers’ data. This will help you gauge the efficacy of your recommendation strategy and optimize in record time.

Besides, Improvado can also help you build custom eCommerce dashboards to unify and visualize eCommerce data from over 300+ sources in real-time. Click on the image below to get your eCommerce dashboard template

When it comes to product recommendations, data is key. Without high-quality data, your recommender system will not be able to generate accurate recommendations. Tidying up your marketing data and structuring insights in centralized storage will help you achieve better ROI on your product recommendation activities. Book a call with us to learn more.

Product recommendation engines typically come with a number of strategies out of the box.

Generally, the higher the number of product recommendation strategies, the better.

Pay Attention to the Algorithm

Product recommendation systems rely on various kinds of data filtering algorithms to function. The major ones include content-based filtering, collaborative filtering, and hybrid recommendation.

Modern engines adopt hybrid recommendation because it combines the power of content-based and collaborative filtering systems. Algorithms can determine how fast you generate profit from recommendations, so it is important that you pay attention to them.

Compare Several Engines Using A/B Testing

A/B Testing allows you to compare two product recommendation engines side-by-side to find the one that best suits your needs.

There are several tools you can use for A/B Testing. A few include Google Optimize, VWO, Optimizely, and more.

Ensure That the Engine is Proven in Your Vertical

It is advisable to go for a reco engine that has a case study, demonstrating its impact on ROI and valuable marketing metrics within your vertical. If a product recommendation engine doesn't have use cases or testimonials related to your business type, then it's probably better to look elsewhere.

Consider the Customer Support

Customer support is a valuable aspect of every product. Ideally, you should consider vendors with responsive customer support teams. This will ensure that you can get assisted any time you run into issues and jump back on track as soon as possible.
