There's a reason Amazon is the world's largest online retailer and it's not just their prices or fast shipping.
It's how they make you feel understood as a shopper.
You land on a product page and immediately see "Frequently Bought Together" , a curated set of items that go perfectly with what you're already looking at. You didn't ask for recommendations. You didn't search for add-ons. Amazon just knew. And before you realize it, you've added three items to your cart instead of one.
This recommendation engine is one of Amazon's most valuable revenue-driving features. Studies have shown that product recommendations account for a significant portion of Amazon's total revenue, all because they show the right products at the right time.
Here's the thing: you don't need Amazon's budget or engineering team to replicate this on your Shopify store. With the right app, you can add the exact same Amazon-style "Frequently Bought Together" experience to your product pages today, for free.
This article will show you exactly what Amazon-style recommendations look like, why they work so well psychologically, and how to implement them on your Shopify store step by step.
What Makes Amazon's "Frequently Bought Together" So Effective?
Before we talk about implementation, it's worth understanding why this feature works so well. Because when you understand the psychology, you'll set up your own bundles far more effectively.
It Meets Customers at the Moment of Maximum Intent
When a customer is on a product page, they're not just browsing, they're actively considering a purchase. This is the single highest-intent moment in the entire shopping journey. Showing a relevant bundle recommendation right at this moment is like a helpful store assistant saying, "Most people also pick these up while they're here."
It Reduces Decision Fatigue
Shopping for multiple related products separately is exhausting. Customers have to search, evaluate, and decide multiple times. When you bundle those products together and present them as a single decision, especially with a discount attached, you eliminate friction and make the "yes" much easier.
It Leverages Social Proof
The phrase "frequently bought together" implies that other customers have already made this combination work. That's subtle but powerful social proof. It signals: "You're not the first person to think of this. Others have done it and it made sense."
It Creates a Perceived Deal
Even a modest discount on a bundle makes customers feel like they're getting a better deal than buying items separately. The psychological win of "saving" something, even a small amount, is a powerful purchase motivator.
What Amazon-Style Recommendations Look Like in Practice
The classic Amazon FBT widget has a few defining characteristics:
- It appears directly on the product page, below the main product details
- It shows the primary product alongside 2–3 companion items
- Each product has a checkbox so customers can deselect items they don't want
- A combined price and discount is clearly shown
- There's a single "Add all to cart" button This layout is instantly recognizable to online shoppers worldwide. They've been trained by years of Amazon shopping to understand and trust it. When your Shopify store replicates this exact experience, customers feel at home and they respond accordingly.
How to Add Amazon-Style Recommendations to Your Shopify Store
What You'll Need
- A Shopify store (any plan)
- The Frequently Bought Together IA app for free, available on the Shopify App Store
- 10–15 minutes That's it. No developer. No theme editing. No custom code.
Step 1: Install Frequently Bought Together IA
Head to the Shopify App Store and search for Frequently Bought Together IA, or go directly to:
👉 apps.shopify.com/frequently-bought-together-bundles
Click Install and authorize the app to connect with your store. Once installed, you'll find it under Apps in your Shopify Admin.
Step 2: Set Up Your First Amazon-Style Bundle
Open the app and click Create Bundle. This is where you design the recommendation that will appear on your product page.
Choose your primary product — this is the product page where the FBT widget will show up. Think of your bestsellers first; those pages get the most traffic and will generate the fastest results.
Select your companion products — pick 2 to 3 items that naturally complement the primary product. The key word here is naturally. The best bundles are ones where a customer would realistically buy all the items together. Ask yourself: "What does someone who buys this product almost always need alongside it?"
Step 3: Configure Your Recommendation Logic
Unlike Amazon, which relies on massive purchase data to generate automatic recommendations, Frequently Bought Together IA gives you manual control — which is actually an advantage for most Shopify stores because you know your products and customers better than any algorithm does.
The app offers three recommendation modes:
Manual Mode — You select exactly which products appear together. This is the most effective approach for stores with a curated catalog where the bundle pairings are obvious and intentional.
Filter-Based Mode — Automatically pull recommendations based on product type, tag, vendor, or collection. For example: "Always recommend products from the same collection as the primary item." This is great for stores with large catalogs where manual curation would take too long.
Global Recommendations — Set a default fallback recommendation that applies to any product page that doesn't have a specific manual bundle assigned. This ensures every single product page on your store always shows a bundle widget — no gaps.
Using a combination of all three gives you maximum coverage with minimum manual effort.
Step 4: Add a Bundle Discount
Amazon doesn't always offer discounts on their FBT bundles — but you're not Amazon. You're a Shopify store competing for attention, and a smart discount is one of your best conversion tools.
Frequently Bought Together IA supports four discount types:
- *Percentage Off *— "Save 15% when you buy all three." Works best when the total bundle value is high and the percentage feels meaningful.
- *Fixed Amount Off *— "Save $8 when you buy all three." Works best when you want the savings to feel concrete and predictable.
- *Free Product *— Add one of the bundle items at no cost. "Buy 2, get 1 free" is one of the most time-tested offers in retail and converts exceptionally well across almost every product category.
- Free Shipping — Remove the shipping fee when the customer purchases the full bundle. This is highly effective because shipping costs are consistently the #1 reason customers abandon their carts.
Pro tip: Test your discount type. Start with a percentage discount, then try free shipping, and compare conversion rates over 2–3 weeks. The winning offer varies by niche and audience.
Step 5: Design the Widget to Match Your Store
This is what separates a polished, professional Amazon-style widget from one that looks like an afterthought.
Frequently Bought Together IA gives you full visual control over the bundle widget:
- Background and border colors — Match your store's color palette
- Button color and text — Customize the "Add all to cart" button to match your theme's CTA style
- Font style — Align with your store's typography
- Section heading — Change "Frequently Bought Together" to whatever language fits your brand voice
- Widget placement — Control where on the product page the bundle section appears All of this is done through a visual editor — no CSS, no HTML, no code. Take 5 minutes to get this right. A widget that blends seamlessly with your store design converts significantly better than one that looks bolted on.
Step 6: Handle Exclusions and Edge Cases
Two more settings worth configuring before you go live:
Product Exclusions — Remove specific products from ever appearing as recommendations. Useful for out-of-stock items, discontinued products, or anything you don't want associated with certain bundles.
Randomization — Enable this to rotate which recommended products appear when multiple options are available. This keeps the widget fresh for repeat visitors and increases the chance of surfacing the right combination for each customer.
Step 7: Preview, Publish, and Go Live
Use the app's preview mode to see exactly how your widget will look on a real product page on both desktop and mobile. The widget is fully responsive, but always verify it looks right on your specific theme before going live.
Once you're satisfied, publish. Your Amazon-style "Frequently Bought Together" section is now live on your Shopify store.
Measuring the Impact
After your bundles go live, track these key metrics:
-** Average Order Value (AOV)** — The most direct measure of bundle success. Even a 10–15% increase in AOV across your store can dramatically impact monthly revenue.
- Bundle Add-to-Cart Rate — What percentage of customers viewing a bundle are clicking "Add all to cart"?
- Revenue Per Session — Are visitors generating more revenue per visit since the bundles went live? Review these numbers after 2–4 weeks. Use what you learn to refine your bundles, better product pairings, better discount types, better widget placement.
Why Shopify Stores That Do This Win
The eCommerce stores that grow fastest aren't necessarily the ones spending the most on ads. They're the ones that extract the most value from the traffic they already have.
Adding Amazon-style product recommendations to your Shopify store is one of the highest-leverage moves you can make because:
- It costs nothing (the app is free)
- It takes less than 15 minutes to set up
- It works on every product page, 24/7, automatically
- It improves with every optimization you make Your competitors who don't have this feature are leaving money on the table with every visitor. The ones who do are quietly building a revenue advantage you can replicate right now.
Final Thoughts
Amazon built their recommendation engine over two decades with billions in investment. You can replicate the core of it, the "Frequently Bought Together" experience that drives such a significant share of their sales on your Shopify store today, for free, in under 15 minutes.
There's no coding required. No developer needed. Just the right app and a clear understanding of your products and customers.
