What if your next revenue boost didn’t require more traffic or ad spend, but simply smarter product suggestions? That’s the power of cross-selling strategies in eCommerce. You should recommend relevant add-ons or complementary products during the shopping journey and increase Average Order Value (AOV), deepen customer engagement, and improve the overall shopping experience - all at once.
It’s important to distinguish cross-selling from upselling.
Used well, cross-selling is not sales - it is smart, timely, and genuinely helpful. In this blog post, we will explore why cross-selling in eCommerce works, unpack proven cross-selling examples, and show you how to implement high-converting strategies that drive results.
Cross-selling is the practice of suggesting complementary products to customers based on what they are currently viewing or have already added to their cart. It is a powerful strategy that increases your AOV and boosts the overall shopping experience by anticipating customer needs.
For example, if a shopper buys a laptop, a well-placed cross-sell can suggest a laptop bag, wireless mouse, or external hard drive. These are not upgrades, but they are useful related products that naturally fit with the main purchase.
Cross-selling can be implemented across multiple touchpoints, on product pages, during checkout, in post-purchase emails, and even in retargeting campaigns. More importantly, it drives revenue without increasing traffic or acquisition costs, making it one of the most cost-effective growth levers in any eCommerce playbook.
While often confused, cross-selling and upselling are distinct but complementary tactics:
Both strategies work best when personalized and timely, but cross-selling strategies stand out in flexibility. It can be applied throughout the customer journey, from discovery to checkout to post-purchase, making it a consistent driver of engagement and conversion.
The effectiveness of cross-selling strategies lies in psychology, in understanding shopper intent and timing. When done right, cross-selling feels like helpful guidance that makes the customer’s life easier.
Shoppers often arrive at an online store with a narrow focus: a problem they want to solve or a specific product in mind. Cross-selling introduces complementary products that they may not have considered but are genuinely useful. This taps into a powerful principle known as "solution bundling", helping customers get more value out of their original purchase.
It also reduces decision fatigue. Rather than forcing customers to browse endlessly, cross-selling makes their next step obvious.
Smart cross-selling in eCommerce satisfies unspoken needs, increases trust, and boosts AOV, all without additional marketing spend.
Effective cross-selling strategies are rooted in relevance and timing. It is not about showing more products, but showing the right products. When cross-sell offers are personalized, well-priced, and timely, they drive more value for the customer and more revenue for your business. Here are the key best practices for implementing cross-selling in eCommerce:
Personalization is the backbone of successful cross-selling in eCommerce, and it starts with data. Generic product suggestions often fall flat because they don’t match individual customer needs or context. That’s where data-driven cross-selling makes the difference.
Brands can present product recommendations that feel timely, relevant, and helpful after using real-time behavioral data. For example, if a customer is browsing a tent, they are likely to respond better to suggestions like sleeping bags than to generic outdoor gear.
Crobox’s Product Finder takes this one step further. It uses behavioral science and AI to identify shopper intent and surface cross-sell products based on what customers actually care about, not just what is in the cart. This results in smarter product discovery, higher engagement, and more meaningful cross-selling outcomes.
Top-performing brands don’t treat cross-selling as a second-hand strategy because they integrate it smoothly into the shopping experience to boost AOV, improve retention, and impress customers. Below are creative and effective cross-selling examples that showcase how smart execution leads to real results:
1. Sephora – Product Pairing Based on Skin Type
Sephora recommends complementary skincare or makeup items based on the shopper’s selected skin concerns or tones. This highly personalized cross-selling approach drives repeat purchases and customer loyalty.
2. ASOS – Style the Look
Fashion retailer ASOS includes a “Style It With” section under product pages to suggest full outfit combinations. These curated looks increase both engagement and multi-item purchases by making styling easy for the customer.
3. Apple – Device Ecosystem Bundling
Apple’s checkout cross-sell flow encourages customers to add accessories like AirPods, cases, and chargers when purchasing devices. It strengthens the ecosystem, increases the attachment rate, and improves the product experience.
4. IKEA – Complete the Room
IKEA recommends products that match the selected furniture style, like rugs, lighting, and storage for a specific room. This smart cross-selling tactic supports inspiration-driven buying and boosts total basket value.
5. Nike – Personalized Product Recommendations Post-Purchase
Nike uses purchase data to send post-checkout cross-sell emails featuring accessories or apparel that match previous orders. This strategy extends the journey beyond checkout, increasing customer lifetime value.
This section is reserved for the essential steps of creating an effective cross-selling strategy that boosts the customer experience while driving incremental revenue. To do it right, let’s see how it works:
Start by studying what your customers buy together when they abandon carts, and how they navigate your store. Look for patterns in purchase history, browsing data, and customer segments to identify natural product pairings.
Generic suggestions rarely convert. Instead, personalize cross-sell offers based on each customer’s interests, preferences, and journey stage. This leads to more relevant offers and better engagement.
Run controlled experiments to test which cross-sell formats, placements (product page vs. cart), and messages perform best. Use data to iterate and continuously improve your cross-selling eCommerce performance.
