Everyone’s talking about personalization and customization in ecommerce. But when it comes to actually implementing them, you’re left wondering—what’s the difference, who’s doing it right, and how can I do the same without breaking the bank… or my tech stack?

In this guide, we’ll break it down with real-world examples of both strategies in action and tips to help you get started—without needing a data science team or a massive rebrand.

Let’s dive in!

Personalization and customization in ecommerce: what’s the difference?

You’ve probably seen both terms thrown around in ecommerce circles, often used like they mean the same thing. But while they’re related, they solve very different problems—and serve different goals.

So, what exactly sets them apart? Let’s break it down.

What is e-commerce customization?

Customization is when users take the wheel and tailor their own experience.

This could be anything from choosing a product color to selecting features, uploading a design, or configuring components. The key here is that the customer is actively involved in shaping the final product or journey.

It works best when shoppers want something unique or tailored to their tastes. Think of it like ordering a burger exactly how you like it—no onions, extra pickles. That’s customization in action.

What is e-commerce personalization?

Personalization, on the other hand, is driven by data—not user input. It happens behind the scenes. The website (or app) adjusts its content, product recommendations, offers, or messaging based on what it knows about the user to enhance customer satisfaction.

This could include purchase history, purchase behavior, location, device type, or even time of day. So instead of asking the customer what they want, you predict it—and serve it up automatically.

The goal? To make the experience feel relevant, seamless, and almost instinctively helpful, increasing customer satisfaction and loyalty in the process.

Why the distinction matters in ecommerce

Knowing the difference between personalization and customization helps you design better experiences.

Personalization is automated and scalable—it tailors the shopping journey with little effort from the user. Customization is more hands-on, giving users control and boosting emotional connection.

For UX, personalization keeps things smooth. Customization makes it feel personal. Used together, they can seriously boost satisfaction and customer engagement.

8 ecommerce customization examples

So, how are brands actually using customization to wow customers? Let’s look at a few standout examples.

1. Nike by You

Nike lets customers design their own sneakers with Nike By You. From choosing the colors and materials to adding custom text, users can create something truly personal.

This strategy doesn’t just sell shoes—it builds emotional ownership. When a customer customizes their own design, they’re not just buying a product; they’re investing in their own creation.

2. Function of Beauty

Ever wish your shampoo was made just for you? Function of Beauty makes that a reality.

It starts with a detailed hair quiz.

Based on the answers, customers get a formula tailored to their hair goals.

It’s a clever way to gather data while also engaging users—and the end result feels both personal and premium.

3. TeeSpring

TeeSpring gives creators the tools to design and sell custom merch, from mugs to hoodies.

Users can upload their own designs or create new ones using TeeSpring’s editor. This level of creative control has helped TeeSpring become a go-to platform for creators and influencers looking to build their brand.

4. Michael Kors

Even luxury brands are getting in on the customization game.

Michael Kors lets customers personalize select products with monograms or custom messages. It’s a small touch, but one that adds exclusivity and uniqueness—two things luxury shoppers love.

5. Chilly’s Bottles

Chilly’s gives customers the power to design their own reusable bottles with a full suite of customization options. From picking lid, body, and base colors to engraving personalized text, shoppers can create a bottle that reflects their unique style.

This hands-on design journey boosts user engagement and creates a sense of ownership, driving up perceived value and conversion rates.

6. Cadbury

Cadbury brings a sweet twist to personalization by letting customers add names or short messages directly to their chocolate bar wrappers. It’s a simple customization, but it transforms a common treat into a thoughtful, personalized gift.

This strategy shines during holidays, birthdays, and seasonal promotions. It’s a low-effort, high-impact way to create emotional resonance with buyers, especially in gift-giving moments.

7. Casetify

Casetify lets users build custom phone cases from scratch. Customers start by selecting their phone model, then choose the case type and layout, and finally upload photos, graphics, or text to make it uniquely theirs.

8. Brooklinen

Brooklinen elevates the bedding shopping experience by letting customers mix and match sheet colors, fabric types, patterns, and finishes to create a personalized bedding set. The customization is both aesthetic and functional, appealing to personal taste and sleep preferences.

As users build their set, they see live price updates—this removes surprises at checkout and makes the process feel transparent and premium. This approach not only enhances the user experience but also increases average order value (AOV) by encouraging bundle building.

4. Obvi’s landing page personalization

Online store Obvi takes their ecommerce personalization strategy to the next level by tailoring their landing pages based on the specific goals that attracted users through their ads.

For example, users who click on weight loss ads are directed to pages focused entirely on weight management—featuring relevant products, testimonials, and benefits.

Meanwhile, those who engage with ads about sleep solutions land on a completely different experience focused on rest and recovery.

By aligning ad messaging with on-site content, Obvi creates a seamless and personalized customer experience that feels hyper-relevant to each shopper.

It’s a smart, granular approach that turns clicks into conversions.

Here’s how you can get started.

5. Hobbs’ intelligent styling recommendations

Hobbs uses smart personalization to recommend complementary items that pair perfectly with what a customer is browsing. It’s like having a helpful in-store stylist suggesting ways to pull an outfit together.

This approach helps shoppers visualize the full look—making the product feel more wearable and real in their lives. It also subtly encourages larger baskets by showcasing items that naturally complete the purchase.

6. Thinx’s goal-based personalization quiz

Thinx uses a goal-driven quiz to tailor its offerings. Visitors answer a few quick questions about their needs—whether it’s menstrual protection, postpartum care, or incontinence solutions.

Based on the answers, Thinx delivers a personalized product recommendation that speaks directly to the shopper’s situation. This not only improves relevance but also builds trust and streamlines the purchase journey.

Additionally, ASOS offers personalized sizing advice based on past purchases and returns—helping reduce fit-related returns and improving customer satisfaction across the board.

8. Baby Björn’s additional accessories

BabyBjörn enhances product personalization by recommending compatible accessories once a shopper adds a baby carrier to their cart.

From teething pads to weather covers, customers can tailor the carrier to suit their lifestyle and needs.

This upsell strategy feels organic and helpful—not pushy—encouraging customers to build a fully customized kit for their little one while increasing cart value.

When to use personalization vs. customization in your ecommerce strategy

So, should you go all in on one strategy? Not necessarily.

Use customization when your product lends itself to user input—think apparel, gifts, or beauty. It works best when customers enjoy being part of the process.

Use personalization when you have access to good customer data and want to streamline the journey. It’s ideal for stores with high traffic, multiple product categories, or returning users.

If possible, use both. The best ecommerce brands combine automated personalization with optional customization to deliver a standout experience.
