AI/ML in Ecommerce Personalisation: How Retailers Turn Customer Data into Sales

Every visitor to your ecommerce store leaves a trail of behavioral signals. These can be queries, scrolls, clicks, pauses, additions to cart, and completed purchases. Most retailers gather this information, but few effectively capitalise on it. This is where AI/ML in ecommerce can generate substantial value for businesses. Instead of using the same homepage for every customer, a retailer can dynamically alter offers, recommendations, and product placements on a per-visitor basis.

Companies that want to accelerate their time-to-value in AI/ML for ecommerce tend to partner with third-party providers. They help with bespoke AI development solutions for ecommerce for their particular catalog, customers, and infrastructure.

Let us discuss how personalisation works, which use cases bring maximum ROI, and how to get started with AI retail solutions.

What is AI in eCommerce Personalisation?

Retailers used to group customers broadly as per their age, geography, or past purchases, and send similar marketing emails. While this approach had decent ROI, it was relatively crude since it relied on aggregated segments. Today, AI/ML in ecommerce can operate at a much finer level by analysing each customer’s behavior and comparing it to similar individuals in real-time. If one visitor shops for running shoes on a Monday evening from their phone, and another browses the same category on a Sunday afternoon from their desktop, each will see a different recommendation on the homepage.

Customers are increasingly demanding more personalised shopping with AI experiences. They are unforgiving toward generic banners and will quickly abandon a site if they cannot find what they need. In contrast, smart personalisation helps drive engagement by providing a tailored AI customer experience. For example, users who receive relevant recommendations tend to spend more time on the site, view more products, and return more often.

AI eCommerce personalisation has evolved from a shiny stack into a critical growth necessity for companies of all sizes. It increases measurable outcomes such as the conversion rate, average order value, and repeat rate for businesses.

According to research, sellers can save an average of nearly 5 hours per week by implementing AI for the right use cases.

How AI/ML in Ecommerce Turns Raw Data Into Actions

At a fundamental level, AI/ML for ecommerce turns raw data into predictions about what a customer is likely to do next. There are three core elements to this process: data itself, predictive models, and the personalisation “actions.”

1. Customer Data Personalisation for eCommerce

To make accurate predictions, every personalisation model for ecommerce requires data about what customers do on the website or mobile application. Customer data personalisation (CDP) platforms bring together first-party data from multiple sources. These can be the website, app, CRM system, and frontline staff, about an individual’s behavior, preferences, and past purchases. The more comprehensive the view of each customer’s journey, the better the predictive models for AI-driven ecommerce can be.

2. Machine Learning Predictive Models for Ecommerce

Machine Learning in ecommerce comes in various forms, but they all share a common goal: using information about past customer behavior to generate predictions about future purchases. Predictive models for personalisation commonly implement an amalgamation of the following three techniques:

A. Collaborative filtering

• This approach in AI/ML for eCommerce analyses which products were bought or viewed by similar customers and recommends those items to a visitor.

B. Content-based filtering

• This technique for personalisation in ecommerce focuses on the characteristics of products that a customer viewed, searched for, or purchased and recommends similar ones.

C. Deep learning and reinforcement learning

• These advanced ML techniques in ecommerce can analyse unstructured data, including images and text. They automatically identify patterns in how individual customers behave. They allow an AI recommendation engine for ecommerce to optimise product recommendations, merchandising, and marketing in real-time.

3. Personalisation Actions in eCommerce

Predictions only create value when they trigger action. Personalisation actions are the visible outcomes shoppers experience. They can be tailored product recommendations, customised homepages, dynamic pricing and offers, personalised search results, and timely emails or push notifications. These actions improve engagement, increase conversion rates, and build long-term customer loyalty by delivering the right message at the right moment.

Top Use Cases for Ecommerce Personalisation With AI/ML

Not every personalisation initiative is created equal, and savvy retailers typically start with a select set of high-impact applications. AI/ML in ecommerce can be leveraged to recommend products, optimise search results, power dynamic pricing, suggest related items, detect fraud, and forecast demand. All of these use cases share the common characteristic of utilising data about past customer behavior and using it to predict future actions.

The list below contains the most impactful applications of personalisation in ecommerce, ordered by their potential impact and speed of implementation.

1. Personalised Product Recommendations for Ecommerce

An eCommerce recommendation engine can suggest which products to promote and on which channel. For example, the homepage, the product page itself, push notifications, or emails, etc. Such recommendations in AI/ML for ecommerce can be tailored to each visitor’s preferences while also taking into account business objectives (e.g., profit margins, inventory levels).

For most retailers, product recommendations with AI/ML present a significant growth opportunity, as they can drive a substantial amount of sales (sometimes in excess of 50% of total revenue).

2. Smart Search in AI/ML-Driven Ecommerce

Personalisation in ecommerce search engines can increase conversion rate by making it easier for customers to find products. AI/ML for ecommerce can be utilised to rank search results according to individual customers’ intent, while also suggesting relevant products on category pages.

For instance, machine learning in ecommerce can help suggest the right size for a given apparel product or recommend items that are similar to those a customer previously viewed or purchased. Moreover, personalised shopping with AI helps process natural language queries and interpret typos or alternative spellings.

3. Predictive Personalisation for Ecommerce

Personalisation for predictive analytics in ecommerce can help take action before customers have explicitly stated their intent. Various machine learning models in ecommerce can predict the likelihood of a purchase, recommend products that a customer is likely to buy, or even identify when an active session is likely to end.

This type of AI/ML in ecommerce helps notify the customer when an item they have been looking for is back in stock. Relevant add-ons,  abandoned cart, and notifications for AI product recommendations are also supported.

4. Marketing Personalisation in Ecommerce with AI/ML

AI in eCommerce personalisation can enhance engagement and increase sales along with dynamic email marketing. By analysing customers’ behavioral signals on the website and mobile app, AI/ML for ecommerce can decide what to say, when to send, and how to format the message.

For example, text-only vs. image-heavy. Similar approaches in ecommerce AI solutions can be utilised to suggest the most relevant promotions for individual customers, recommend products to return, and optimise push notification campaigns.

5. Pricing, Chatbots, and Operations Personalisation for Ecommerce

AI/ML for ecommerce can be leveraged to establish the optimal price for an individual customer, taking into account their behavior, demographics, and purchase history.

Smart assistants in ecommerce can help answer frequently asked questions, such as about returns, and support customers in choosing the right size or other attributes.

E-Commerce automation with AI helps sort orders, refund requests, and other messages to speed up operations.

What Data Is Needed for Personalisation in Ecommerce?

There are various data sources for AI eCommerce personalisation. We have listed the four major categories of data needed for training an AI model for eCommerce. 

1. Behavioral data

• It represents what customers do on the website or mobile app. This includes clicks, page views, searches, scrolls, and other actions. 

2. Transactional data

• It concerns what a customer purchased or attempted to purchase on the website. 

3. Profiling data

• This represents what is known about the customer’s age, gender, etc., and their behavior segments. 

4. Contextual data

• It captures the customer’s device, location, time of day, and other relevant information.

The Role of Privacy in Ecommerce Personalisation with AI/ML

When it comes to personalisation in ecommerce, data privacy regulations are an important consideration. Multiple such laws and regulations are applicable, including GDPR in Europe and the upcoming DPDP Act in India.

When designing a CDP for machine learning in ecommerce personalisation, it is critical to store only the data that can be justified. For instance, with explicit customer consent. Furthermore, data privacy laws often restrict how such information can be processed and utilised, which requires careful design.

Business Impact of Personalisation in Ecommerce

AI in ecommerce personalisation can have a substantial impact on businesses. By providing more relevant product recommendations and bundles, smart personalisation tends to increase the conversion rate, average order value, and overall satisfaction of customers.

A dynamic recommendation engine for ecommerce can help eliminate irrelevant suggestions that would otherwise annoy the customer and erode margins due to excessive discounting. As customers see more value, they tend to return to the website or mobile app more often, boosting retention and lifetime value.

Common Challenges for AI in Ecommerce Personalisation

AI has proven immensely useful in eCommerce personalisation. But there are a few hurdles along this path that need to be taken care of. Some of the most common challenges that developers and businesses face include:

1. Data Fragmentation and Data Quality Issues

It is not uncommon for large-scale ecommerce players to have their data stored in silos across different systems. Data integration for personalisation in ecommerce typically requires a CDP that operates as a central repository of information about the customer journey. In addition to building a unified view of the customer, data quality checks should be performed to ensure that the model is trained on accurate information.

2. The Cold Start Problem in Ecommerce Personalisation

One of the common challenges with ML algorithms for personalisation in ecommerce is that they typically require historical data about a customer’s behavior to make relevant product recommendations. eCommerce AI solutions usually do not have behavioural data for new visitors. This makes it challenging to suggest products that they might find interesting. There are multiple approaches to tackle this issue, including utilising collaborative filtering and demographic data to make initial recommendations.

3. Transparency and Trust in Ecommerce Personalisation

Many consumers are concerned about how their data is used, which makes it essential for businesses to be transparent about how personalisation in AI/ML for ecommerce works. Businesses should give customers control over their personal data. Avoid using intrusive tactics like showing retargeting banners. By building trust with consumers, organisations can improve their long-term revenue from personalisation initiatives.

4. Measuring the Impact of Personalisation in Ecommerce

It is critical to measure the impact of AI in ecommerce personalisation on business metrics. A/B testing is a common technique that can be utilised to gauge the impact of a recommendation engine for ecommerce. By splitting the traffic into a control group and an experimental one, businesses can compare metrics such as conversion rate or revenue per visitor. Ultimately, personalisation in ML for ecommerce should be evaluated based on its impact on business goals, not merely on theoretical metrics.

A Roadmap for Getting Started With Ecommerce Personalisation

There are several steps that most companies need to undertake before launching a personalisation initiative. Below is a sample roadmap for getting started with implementing eCommerce AI solutions:

Define clear objectives

• Every personalisation initiative should have clearly defined objectives. A business could aim to increase the conversion rate, average order value, or retention, or reduce the rate of returns.

Assess the data

• It is critical to analyse which data sources are available for training a recommendation engine for eCommerce. The quality of data has a direct impact on the outcome.

Decide on use cases

• It is advisable to prioritise use cases that have the potential to deliver the most value. Product recommendations for an AI/ML ecommerce platform are often a good place to start due to their relative ease and high impact.

Prepare data pipeline

• It is necessary to create a reliable data stream that can be used for training and testing. This could involve setting up a CDP, defining customer segments, etc.

Select an approach

• Most companies can benefit from utilising existing AI retail solutions for recommendation engines. At the same time, custom models may be required for specific applications.

Test and iterate

• Dynamic recommendation engines for ecommerce typically require a substantial amount of testing before they can deliver the desired result. It is important to run A/B tests and analyse the impact on key metrics.

Scale personalisation

• Once an effective personalisation model has been validated, it can be expanded to other channels and functions such as email marketing, pricing, etc. More mature companies can begin using AI/ML for ecommerce personalisation across all channels and touchpoints.

Evaluating Potential Partners for Ecommerce Personalisation

When selecting an external partner for AI-powered ecommerce solutions, it is advisable to conduct due diligence. Ideally, the vendor should have experience in AI/ML for retail and have successfully delivered personalisation initiatives for other ecommerce companies.

The expertise of a potential partner is of particular importance when it comes to data engineering, predictive modeling, and system integration. Also, ask about their approach to data privacy and transparency. Lastly, request references and ask how they measure the business impact of personalisation in ecommerce.
