Using E-commerce Data to Predict Customer Behavior and Boost Online Sales

E-commerce has become a part of our lives as part of the Digital Economy.

Businesses generate vast amounts of data through online sales every second, including all consumer clicks, searches, product views on widgets, and cart additions, as well as completed purchases.

Many online businesses track data generated by consumers; however, very few use this data to better understand their customers and develop business strategies for growth.

E-commerce provides tools to predict customer trends from online shopping behaviour and the opportunity to make predictions based on the information available to online stores.

This article outlines how e-commerce datasets provide insight into consumer trends; the types of e-commerce data that are valuable to a business; and the best approaches for driving profitable revenue through predictive analysis of your customers' shopping experiences and purchases.

From Descriptive to Predictive Analytics

E-commerce analytic tools have focused on what is already occurring (last month’s revenue, highest selling product, and average order value), while predictive customer analytic tools allow online retailers to forecast events that will take place in the future (predictions are based on customers' historical behaviour):

  •  Who are the most likely customers to transact with (buy from) your site?
  •  Who is likely to leave your business?
  •  What products are likely to be of interest to a particular customer?
  •  At what time will you send a promotional offer to the defined customer group?

“The data doesn’t mean anything on its own. Target’s good at figuring out the really clever questions.” — Eric Siegel, Founder of Predictive Analytics World

Predictive models identify customer trends and behaviours using past and present data, helping determine possible outcomes of customer interactions and helping retailers prepare for future interactions.

Retailers have changed from being reactive with respect to making customer-related decisions to proactively developing strategic plans that offer the most appropriate opportunities (consumer products) to their customers when the customers are most likely to take action.

Core Types of E-commerce Data Used for Prediction

There are numerous aspects of ecommerce that should be considered when building accurate predictive models.

1. Behavioral Data (Clicks, Views, Cart Activity)

Behavioral data captures how users interact with your website and mobile app, e.g., page views, search queries, click paths, how long they stay on pages, what gets added to the cart, and checkout behaviour.

Users' browsing behaviours often indicate whether they’re going to buy or hold off on buying something, and therefore, this data is critical for creating predictive conversion models.

2. Transactional Data (Purchases, Frequency, Returns)

Transactional data consists of an individual's previous purchases, how often they purchased items, the average dollar amount of their purchases, when and how they purchased items, and how many items they returned.

Meaningful information can be derived from transaction history, including lifetime value, repeat-purchase likelihood, and customer loyalty, ultimately leading to accurate predictive lifetime value models.

3. Customer Profile & Demographic Data

A customer profile data set contains various demographic fields (age, sex, income level, etc.) as well as geographic location, the type of device they are using to access your store and any associated customer account details.

When combined with behavioral and transactional data, you can create highly accurate customer segmentation and personalize the shopping experience.

4. Product, Pricing, and Inventory Data

Product categories, pricing history, available inventory and discount structures impact how and why customers buy items.

Predictive models can use product and inventory data to effectively forecast customer purchase demand, make sound product recommendation decisions and optimize pricing strategies.

Elements such as seasonality, holidays, promotional events, social trends, and even local weather patterns can also affect how buyers behave.

If you incorporate these external signals when developing predictive models, you will improve the accuracy of your demand forecasting, campaign planning, etc. 

How Predictive Models Forecast Customer Behavior

After businesses aggregate their data, they can use predictive modeling techniques to analyze and forecast customer behavior.

Purchase Propensity Modeling

By utilizing historical data such as product interest, browsing depth, and purchase patterns, companies can estimate which site visitors or customers will buy products within the next few days. These estimates allow businesses to direct targeted campaigns to customers who are most likely to buy products.

Churn Prediction & Retention Signals

Through churn prediction methods, businesses identify customers most likely to stop engaging with the company and/or cease purchasing products.

The warning signs of churn may include reduced frequency of visits to a business's website, lower total order value, or abandoned shopping carts.

Identifying customers at risk of churn allows companies to create strategies to retain them before they leave, such as sending re-engagement emails or personalizing discounts.

Recommendation Engines & Personalization

Recommendation engines use previous purchases and browsing history to predict which products customers are likely to buy next.

With personalized recommendations, a company's conversion rates and average orders will be higher than without them.

Forecasting Customer Lifetime Value (CLV)

Forecasting customer lifetime value provides insight for a business in determining which customers are likely to generate the largest revenue over time; therefore, businesses use this information to allocate their marketing budget, develop loyalty programs, and prioritize customer service efforts.

Turning Predictions Into Revenue Growth

Predictions only don't produce revenue; they require taking action to create revenue. The best value of predictive insights is to incorporate and utilize them into an organization’s daily operations.

Personalized Marketing Campaigns

Marketers can use predictive insights to customize their marketing communications to specific customers.

Businesses can use predictive insights to send customers personalized offers, resources, or replenishment reminders when customers' intent to purchase is highest.

Dynamic Pricing and Promotions

By forecasting demand and pricing, precisely as demand occurs via predictive insights, an organization can adjust or optimize competitive prices or discounts according to the current demand.

Website & Checkout Experience Optimization

The best way to predict a customer's intent to purchase is to personalize the entire browsing and purchasing process. The homepage, search results, basket and checkout processes can dynamically adapt to the customer based on their intent to purchase.

Smart Inventory & Demand Planning

Predictive insights will allow organizations to identify what the most likely products to sell are and which ones can remain in inventory until sold out. The result is the prevention of stockouts, which will lead to better sales and lower costs associated with overstocking inventory.

Customer Retention and Loyalty Strategies

To improve customer retention and loyalty, businesses must first identify which customers are most valuable and which are at risk of leaving.

Businesses can then create tailored incentives and programs designed to keep customers engaged for longer periods. Engaging current customers is generally considered to be more cost-effective than acquiring new customers.

The Role of AI and Machine Learning in Predictive E-commerce

Predictive e-commerce analytics rely heavily upon artificial intelligence (AI) and machine learning (ML). Unlike traditional static rules, ML models continue to grow in accuracy over time as they are fed with additional data.

In addition, ML can process large amounts of data, identify hidden patterns, and adapt to changing customer behaviours.

“Every part of your business will change based on what I consider predictive analytics of the future.” — Ginni Rometty, former CEO of IBM

Many e-commerce companies have invested in vertical AI solutions (i.e., those designed specifically for retail and e-commerce applications) rather than generic analytic tools because vertical AI solutions deliver faster time-to-value for their industry and outperform generic tools.

Vertical AI solutions natively understand the complexities and uniqueness of their respective industries' data structures, performance metrics, and other challenges.

Why High-Quality Data Is Essential for Accurate Predictions

The success of predictive analytics relies heavily on high-quality (clean, accurate, and well-governed) data.

If the data is incomplete or contains biases, predictions made from such datasets will be inaccurate, resulting in a damaged customer experience.

Likewise, businesses must protect their customers' privacy, so they must have approved policies on how they collect, store, and protect customer data and comply with data protection regulations.

Customers desire transparency about how their information will be used; therefore, adherence to these principles helps build long-term trust and loyalty between the customer and the business.

Conclusion

Using e-Commerce data to predict customer behaviour has become increasingly important. As consumers continue to evolve, so too must the retailers that cater to them.

Predictive analytics combines behavioural data, transactional data, and contextual information to help retailers determine customer needs, when customers require a service, and how best to deliver that service.

The predictive value of predictive analytics can drive increased conversion rates, lifetime customer value, and sales growth for retailers that incorporate it into their marketing strategies, personalization techniques, pricing models, and operations.

By applying predictive insights in a data-driven model to produce actionable outcomes, e-Commerce retailers are now better equipped than ever to respond to the growing demands of an increasingly demanding consumer base.
