Increasing average order value is one of the most efficient growth levers in eCommerce. Upselling (encouraging a higher-value version of the chosen product) and cross-selling (suggesting complementary products) can increase revenue by 10-30% without increasing customer acquisition costs. The key is relevance — poorly targeted suggestions feel pushy, while well-matched recommendations feel helpful.
Product Page Upselling
The product page is where upselling is most natural. When a customer is evaluating a specific product, showing a premium alternative alongside a clear value proposition works well. Frame the upsell in terms of benefits, not just price difference. "For $20 more, get the Pro version with 2-year warranty and premium materials" is compelling. Simply listing a more expensive product is not.
Comparison tables on product pages are effective for upselling because they let the customer see exactly what they gain by upgrading. Highlight the differences that matter most to your audience, and use visual cues like a "Most Popular" or "Best Value" badge on the tier you want to promote.
Cross-Selling Strategies
- Frequently bought together: Show products commonly purchased alongside the current item. This leverages real purchase data to make relevant suggestions.
- Complete the look: For fashion and home decor, show styled combinations that include the current product. This turns individual products into aspirational outfits or room settings.
- Essential accessories: Suggest necessary add-ons — a phone case for a phone, batteries for a toy, a mounting bracket for a TV. These feel genuinely helpful rather than promotional.
- Bundle discounts: Offer a small discount when customers buy related items together. "Save 15% when you buy the set" encourages larger orders while giving customers a reason to add more.
Cart and Checkout Opportunities
The cart page is an underutilised cross-selling opportunity. Show relevant add-ons based on the items already in the cart. Keep suggestions limited to 2-3 items to avoid overwhelming the customer. One-click add-to-cart functionality removes friction — the customer should be able to add a suggestion without leaving the cart page.
Free shipping thresholds are a powerful upselling mechanism. "Add $15 more for free shipping" with a specific product suggestion that meets that threshold converts well because the customer perceives the product as essentially free (they would have paid for shipping anyway). Display a progress bar showing how close they are to the threshold.
Post-Purchase Cross-Selling
The confirmation page and follow-up emails are opportunities for cross-selling without disrupting the checkout flow. After purchase, customers are in a buying mindset and have demonstrated trust in your brand. Recommend complementary products in the order confirmation email or on the thank-you page with a time-limited discount to create urgency.
Measuring Impact
Track average order value, items per order, and cross-sell/upsell conversion rate (percentage of customers who add a suggested product). A/B test different recommendation placements, product selections, and copy to find what resonates with your specific audience. At Born Digital, we build recommendation logic and tracking into every eCommerce project so our clients can continuously optimise their upselling and cross-selling strategies.
