How to Create Upsell Offers on Shopify Product Pages (Step-by-Step)

What Are Shopify Product Page Upsells?

Product page upsells are recommendations displayed on Shopify product pages to encourage customers to add complementary items, upgrade to premium versions, or buy bundles. They typically increase average order value by 10-30%.

Unlike post-purchase upsells (which appear after checkout), product page upsells engage customers at the decision-making moment—when they're actively evaluating a purchase.

This is one of the most valuable touchpoints in your store. A customer viewing a phone case is already interested in protecting their phone. Showing them a screen protector or charging cable at that exact moment is helpful, not pushy.

Why Product Page Upsells Increase AOV

Product page upsells are effective because they meet customers where they already are—in shopping mode, actively considering a purchase. Here's why this timing matters:

• High intent moment – The customer found your product and is evaluating it. They're receptive to relevant suggestions.
• Context is clear – You know exactly what they're interested in, making recommendations easy to personalize.
• No interruption – Unlike popups, product page upsells are part of the natural browsing experience.
• Bundle psychology – Seeing complementary products together creates a "complete the set" urge that increases cart size.

According to Shopify's Future of Commerce report, stores using personalized product recommendations see up to 35% growth in average order value^[1]. And a Forrester study found that upselling and cross-selling account for 10-30% of e-commerce revenues^[2].

4 Types of Product Page Upsells

There are four main approaches to product page upselling. Each serves a different purpose:

1. Frequently Bought Together (Bundles)

Shows products commonly purchased together as a bundle with a combined price. Customers can add all items with one click.

• Best for: Accessories, consumables, complementary items

• Example: Phone + Case + Screen Protector bundle

• Typical AOV lift: 15-25%

2. Related Products / Cross-Sells

Displays products in the same category or with similar attributes. Less direct than bundles, but helps customers discover alternatives.

• Best for: Product discovery, showing alternatives

• Example: Similar dresses in different styles or colors

• Typical AOV lift: 5-15%

3. Premium Version Upgrades (True Upsells)

Encourages customers to buy a higher-tier version of the product they're viewing. This is upselling in its purest form.

• Best for: Products with premium variants or tiers

• Example: Basic plan → Pro plan, Standard → Deluxe

• Typical AOV lift: 20-40%

4. Product Add-Ons

Small additions like gift wrapping, extended warranty, or personalization. Often displayed as checkboxes near the Add to Cart button.

• Best for: Services, warranties, customization options

• Example: Add gift wrapping for $5, Add 2-year warranty for $29

• Typical AOV lift: 5-10%

How to Set Up Frequently Bought Together

Frequently Bought Together (FBT) is the most effective product page upsell format. Here's how to implement it properly:

Choosing Products to Bundle

The key to FBT success is relevance. Ask yourself: "Would a customer genuinely want both of these products?"

• Complementary pairs: Camera + Memory Card, Laptop + Laptop Bag
• Consumable add-ons: Razor + Blade Refills, Printer + Ink Cartridges
• Protection products: Phone + Case + Screen Protector
• Complete sets: Shirt + Matching Pants, Skincare Routine Bundle

Pricing Your Bundles

Bundles work best with a small discount that incentivizes buying together:

• 5-10% off total: Gentle nudge without hurting margins
• Fixed amount off: "Save $10 when bought together"
• Free item threshold: "Add the case and get the screen protector free"

Widget Placement

Position your FBT widget where customers will naturally see it:

• Below product description: After they've read about the main product
• Near Add to Cart: Right where the buying decision happens
• Avoid below-the-fold only: Some visibility above the fold increases engagement

Product Page Upsell Best Practices

1. Prioritize Relevance Over Revenue

The highest-margin upsell isn't always the best choice. Recommend products that genuinely enhance the customer's purchase, even if they're lower-priced.

2. Limit Recommendations to 3-4 Products

Too many options cause decision fatigue. Show your top 3-4 most relevant recommendations, not your entire catalog^[3].

3. Use Social Proof

Labels like "Customers also bought" or "Frequently purchased together" leverage social proof psychology. They signal that other buyers found these combinations valuable.

4. Test Different Positions

A/B test widget placement. Some stores see better results with upsells above the fold, others below product details. Data beats assumptions.

5. Mobile Optimization

Over 70% of Shopify traffic is mobile. Ensure your upsell widgets display properly on smaller screens without disrupting the Add to Cart flow.

6. Combine with Post-Purchase

Product page upsells capture customers during browsing. But you can also reach them after purchase via SMS. Upsella sends AI-powered product recommendations via text message after customers buy—extending your upsell window beyond the single session.

Frequently Asked Questions

What is a product page upsell?

A product page upsell is a recommendation shown on your product pages while customers browse. It can be a frequently bought together bundle, related product, premium upgrade, or add-on service. The goal is to increase order value by suggesting relevant additional items.

What's the difference between upselling and cross-selling?

Upselling encourages customers to buy a more expensive version of the same product (Basic → Pro). Cross-selling suggests complementary products (Phone → Phone Case). Both increase AOV, but through different approaches.

Do I need an app for product page upsells?

Not necessarily. Shopify's built-in theme features support basic related products sections for free. However, apps offer advanced features like bundle discounts, AI matching, A/B testing, and detailed analytics that can significantly improve results.

How many products should I recommend?

3-4 products is optimal. Fewer feels sparse; more causes decision fatigue. For frequently bought together bundles, 2-3 complementary items plus the main product works best.

What discount should I offer on bundles?

5-10% is the sweet spot. It's enough to incentivize bundling without significantly hurting margins. Alternatively, offer a fixed amount off (e.g., "Save $15 on this bundle").

Will product page upsells slow down my site?

Well-built apps have minimal performance impact. Native theme features have zero impact. Always test page speed after adding new elements using tools like Google PageSpeed Insights.

Conclusion

Product page upsells are one of the highest-impact, lowest-risk ways to increase your store's revenue. You're not interrupting the buying process—you're enhancing it with relevant suggestions.

Start with Shopify's built-in related products feature to test the concept for free. Once you see results, consider upgrading to a dedicated app like Selleasy or Frequently Bought Together for bundle discounts and better analytics.

And remember: product page upsells only work while customers are browsing. To continue the relationship after they leave, Upsella's SMS upsells reach customers with AI-powered recommendations at key moments—order shipped, delivered, or any custom schedule you set.
