Online Shopping Gets Better x Personalization

Personalization has become a “go-to” strategy in modern eCommerce. Today, customers are truly “spoiled for choice” with endless online options. To get their interest, you need to offer a “personalized” experience—recommending the “specific” products they want, whether it’s the perfect “color/style,” a unique “special offer,” or using “AR” to for a more immersive experience, all powered by “big data.”

Let’s explore the WHY of personalization, the WHAT (common challenges) in implementing it, and HOW retailers can take advantage of it.

Why personalization matters?

In the late 1990s, online shoping was built on a “one-size-fits-all” model. Every visitor—whether a sneaker enthusiast or a dress shoe aficionado—received the same static “Top Picks for You!” list. This generic approach meant that personal tastes were ignored, leaving customers feeling like just another number.

How data & AI changed things

By the 2010s, big data and machine learning emerged as a disruptive new approach to e-commerce. Retailers began to collect detailed insights - from click behaviour to the length of time a customer spent on a product. This data collection boom enabled systems to analyse customer actions in real time. This meant that whenever a shopper was about to leave without making a purchase, the system could instantly trigger a tailored offer, such as a discount or free shipping, transforming hesitation into action.

What customers expect today

Today, online shopping should feel personal—like walking into your favorite local shop where the owner knows your name and exactly what you love. Customers don’t want to waste time searching, endure never-ending checkouts, or feel like just another order number. They crave an experience that’s easy, familiar, and maybe even a little fun. As Steve Jobs once said, “You’ve got to start with the customer experience [CX] and work backwards".

Listen to your CUSTOMERS when they say:

—“Show me what I actually want.”

Recommendations should feel like advice from a trusted friend—“You’ll love this because…”—rather than a generic pitch. Well today you can actually give them what they want through AI-powered engines.

E-commerce is evolving into truly personalized experiences, where every customer finds exactly what they’re looking for. By understanding shopping habits and individual preferences, we create intuitive, trusted recommendations.

For example x Pets4Home, we faced the challenge of guiding customers to products they would love.

We tracked how customers browsed and what they purchased, then used an AI engine to analyze the patterns and deliver personalized suggestions seamlessly integrated into the shopping experience. This approach not only helped customers find what they desired faster but also boosted engagement and sales.

—“Let me shop on my terms.”

Customers expect to pick up where they left off, whether they’re shopping on a phone, laptop, or in-store. Losing progress—like a cart resetting between devices—creates that feeling when you worked for 8 hours straight in a document and you didn’t save it. The fix? Make your systems talk to each other. By integrating your point-of-sale, website, and app with your CRM and inventory software, customer preferences and selections remain intact, ensuring a seamless shopping experience.

—“Don’t make me wait”

People want fast, easy, and 0 problems. A streamlined checkout using secure single sign-on (SSO) and one-click payment systems removes unnecessary steps, making the purchase quick and easy.

—“Tech should help, not just hype.“

People love trends in technology. But they soon can find out that it doesn’t add real value. Use tools like AR for virtual try-ons, AI-powered assistants for real-time guidance, and intuitive size guides but make sure they are what they need and serve their purpose, dont add tech just for the hype.

Personalization challenges (we've met along the way)

Personalizing the customer experience brings many benefits—but it also comes with a set of challenges that retailers must overcome to deliver a seamless experience.

They can be grouped into 3 MAIN AREAS:

SaaS or disconnected tools

Retailers often start with SaaS solutions like Shopify because they’re simple to set up—a great launching pad for eCommerce.

However, as businesses grow, these platforms can limit flexibility; relying on native payments until the need for diverse options or in-store integration arises can lead to delays, inconsistent transactions, and even abandoned carts. Likewise, disconnected internal tools often become outdated, resulting in fragmented processes and lost revenue.

We have encountered such an issue with Pets4Homes. Outdated payment tools meant transactions weren’t properly verified, leaving users exposed to fraudulent charges and financial losses.

We fixed this by refactoring the payment module and replacing it with a modern, escrow-based system integrated with over 40 global processors. Now, every transaction is securely verified and processed in real time.

Many data & sources [big data]

Personalization relies on a lot of data—even small retailers can collect huge amounts, from website clicks to real-time browsing behavior. But gathering this data is only the first step. To avoid offering outdated or irrelevant recommendations, you need efficient systems to store, clean, and analyze the information.

The solution is to use smart tools that centralize your data in one place. This unified approach prevents data silos and ensures that your recommendations are always fresh and accurate. Regular audits help remove duplicates and outdated entries, keeping your system both reliable and efficient.

Efficient data management and synchronization across all channels—website, mobile app, and social commerce—creates a coherent and well-structured ecosystem.

A great example of this is our work with Lensa.ro. They faced the challenge of managing diverse data from both their online store and physical showrooms

By integrating these systems into a seamless omnichannel experience, we helped them gain better control over inventory, customer data, and personalization.

Customer data & legislation

Regulations like GDPR (Europe) and CCPA (USA) mandate transparency in data collection and usage, transforming compliance into a trust-building advantage. Platforms can now track and log user actions automatically, ensuring adherence to legal requirements. Remember the checkbox in front of the Terms & Conditions? It serves as both user notification and platform protection—a win-win.

To further safeguard collected data, implementing robust security measures, such as encryption and regular security audits, is essential in preventing unauthorized access.

High traffic spikes

A personalization feature that runs smoothly for 500 customers can break under the load of 500,000.

We had a situation when Tanzania’s leading online marketplace, launched a large TV ad campaign, resulting in an unexpected traffic surge that led to performance issues and user dissatisfaction. — Marcel

To address this, we migrated their data to a secure cloud environment and adopted DevOps best practices, achieving a scalable infrastructure capable of handling over 2 million active monthly users. This transformation resulted in a 40% increase in customer engagement.

Role of data and feedback

Data shows what happens, but feedback reveals why. Knowing how many people clicked “add to cart” is one thing; understanding why they left without purchasing is another. By blending numbers with actual customer voices, you gain insights that can reshape your approach and strategy to better fit your customer mindset (shopping patterns) and operational efficiency (business money).

Numbers + customer voices

ㅤ• What DATA tells you: Tools like [heatmaps, click paths, CRM logs, and POS systems] reveal actual shopping behaviors and trends.

ㅤ• What CUSTOMERS say: Data like [surveys, polls, social media comments, and reviews] capture the emotions and frustrations behind those actions.

By combining these perspectives, you gain a clear picture of what works and what needs improvement. For instance, if data shows a high checkout drop-off and customers say the process feels too long, you know exactly where to focus your enhancements.

Putting data ‘silos’ together

Often, different tools in your business—like your website analytics, email platform, and in-store systems—collect data separately. When these systems don’t share information, you miss out on the full picture of customer behavior.

Bring all your data together into one integrated system. This “single source of truth” makes it easier to spot trends, understand customer needs, and make adjustments that improve the overall shopping experience. - Marcel

By combining both hard data and customer feedback, and by ensuring all your data works together, you can refine your personalization strategy to truly meet your customers’ needs.

Moving forward x personalization

Personalization turns your store into a space that feels familiar (welcoming) to each shopper. Customers expect brands to understand their preferences, anticipate their needs, and provide a seamless experience across web, mobile, and in-store.

However, many retailers struggle with disconnected SaaS platforms and outdated tools that prevent key systems—like CRM, inventory, and recommendation engines—from working together. When data doesn’t flow freely, personalization efforts fall short, leading to irrelevant recommendations and lost sales.

The solution lies in integrating AI, machine learning, and real-time customer data into a unified system. By analyzing shopping patterns and behavior, retailers can deliver smarter recommendations, optimize pricing, and create smoother shopping experiences.

After 14 years of helping businesses scale, we’ve seen that those who break down data silos and embrace AI-driven personalization don’t just increase sales—they build stronger customer relationships and future-proof their retail experience.
