How product recommendations for eCommerce websites work?


In-store sales consultant asks you about your preferences and then shows you the items accordingly in e-commerce, a software does this automatically. When such a big, successful e-commerce company focuses that much of its resources on something it must be important. This website is one of the main activities in privatization. This feature is called Personal Product Recommendation, which displays suggested items according to algorithms and aggregated data, which are particularly relevant to each individual shopkeeper.

As an e-commerce manager, however, you do not have to wait for someone else to recommend your product to your customers. When you are in the process of shopping on your website, you can make product recommendations. This can be a better online experience in return and the conversion has increased.

How recommendations work?

Amazon provides a great example of a more sophisticated recommendation system (with other recommended things) that suggests stuff for those products that visitors want to buy, based on the fact that other customers have the item, What to buy with it, of course, is a powerful tool to increase the average order values, but a significant amount of customer data to work automatically Process is required.

Frequently Bought Together example

Most of the third-party recommendation engines will suggest suggestions by analyzing shopping behavior with relationships between products and product categories. It uses a large amount of behavioral data to eliminate a small group of products or products.

How to Create Customer Segment

To create customer segments and use those segments to look in the future, what may be the interest in visitors, the engine gets a group of customers whose purchasers overlap with the purchases of the next purchaser. Algorithms collect items from these customers, which eliminate the items purchased by the visitor, and recommend the rest to visitors. A technique called “Collaborative Filtering”.

The engine then offers a series of recommendation lists to be used at different points in the customer journey (e.g. product page, checkout page, search results page, category page, post-visit-emails, etc.). These separate recommendation lists are typically based on the following data:

  • The visitors’s past browsing behaviour (pageviews, clicks, add-to-carts, purchases)
  • Category best sellers or most popular items (most clicked, most purchased by other visitors)
  • High-margin items from the same category as the item being viewed
  • Shipping costs (i.e. listing products with no shipping costs)
  • Search query (i.e. displaying the products that other visitors purchased following the same query)Note: this usually just leads to a redundant list of products already provided as search results. Acting more to reinforce which search result to choose.
  • Complementarity (i.e like Amazon’s suggested accessories lists)
    Note: Amazon has enough data that it can determine what is potentially an accessory by looking at what past customers bought together with the item in question. Retailers that do not have Amazon level data will need to create the associations between products manually – more often relying on basic category structure (e.g. showing a list of Firestick adds when buying firestick )

Product Recommendation

Most recommendation systems will also provide you a configuration interface for creating IF-Then business logic filters that helps you to promote sale, high-margin, low-priced etc.

Finally, nearly all proprietary recommendation solutions will provide functionality for promoting those recommended products through email campaigns as well as through on-site banners and navigation. The better tools will include a way to use the recommended items in display advertising.

You can use product recommendation in a number of ways.

1. You can add recommendations of your own company. These are often products that customers are already purchased.

  • Data sparsity:  For an effective recommendation system you usually need a large number of users who have big conversations with the website. This group of people will have a big impact on how disciplined engines work
  • Cold-start: Depending on the retailer, it can take months to accumulate enough behaviour data.

2. You can highlight the user’s recommendations. These wishlists can be things that your customers share with each other. It also requires the functionality of allowing your site to share items internally on your site, but it can pay dividends.

3. You can use the recommended products to show the products of those products they are currently purchasing. So if someone is buying a Mobile from your electronic shop, you should also show them back cover, earphones or selfie stick so they can buy a group of products that work together.
