Did you know that cross-selling can boost sales by 20% and profits by 30%, according to McKinsey? This strategy is powerful, and one of the easiest ways to upsell & cross-sell on Shopify is by using a “frequently bought together” widget.
In this guide, you’ll learn 2 ways to create an FBT (Frequently bought together) widget:
Plus, we’ll share expert tips to maximize conversions and fix common issues like low engagement or slow page speed. Let’s dive in!
“Frequently Bought Together” widget is a feature suggesting products that customers purchase concurrently with other items. This technique presents complementary products under the product description or at checkout to enable one-time purchasing of necessary items instead of making customers search.
“Frequently Bought Together” widget can also appear in the cart drawer, checkout page, or thank-you page as a final nudge before purchase.
This strategy goes by different names, such as:
No matter what it’s called, the goal is the same: increase the average order value (AOV) by encouraging customers to buy related products in one transaction.
Real-Life Example: Velotric
Just have a look, Velotric uses the “Frequently Bought Together” widget to deliver valuable product bundle deals to customers. Their system implies items such as a front basket, a phone mount, and a water bottle & cage for automatic recommendation while users browse for e-bikes. Customers will find these selected products reinforce the riding experience since they do not contain random items.
Velotric offers attractive deals on combined packages to enhance customer value. Someone who chooses not to purchase the entire bundle might end up buying additional accessories, which increases their total purchase value. Through this smart approach, the brand generated higher sales and improved shopping simplicity and customer satisfaction.
So Why is FBT Important for Shopify Merchants?
For Shopify merchants, increasing AOV is one of the most effective ways to boost revenue without constantly spending more on acquiring new customers. Since digital advertising costs continue to rise, it’s crucial to make every transaction count.
The Shopify analytics app LittleData did a comprehensive survey of Shopify stores’ conversion rates and found the average conversion rate for Shopify stores is 1.4%. This means for 1000 visitors to your store, 14 of them will actually spend money. If your AOV (Average order value) is 30$, you are probably going to earn around 420$.
Now, with an effective upselling & cross-selling strategy using the FBT widget, customers are encouraged to add relevant products to their cart. If the AOV increases to $50, total revenue jumps to $700, without increasing traffic or marketing spend.
This strategy works because the FBT widget encourages customers to buy more by showing relevant add-ons at the right time. Instead of pushing random products, it uses AI to recommend practical, complementary items.
Beyond revenue growth, the “Frequently Bought Together” widget also improves customer satisfaction by simplifying the shopping experience. Instead of leaving the store to search for accessories elsewhere, customers can complete their purchase in one go, saving time and effort.

You can add a “Frequently Bought Together” widget without having to spend extra money for a third-party app by leveraging Shopify’s built-in features and the Search & Discovery app. The process consists of 2 main steps:
Here’s a step-by-step guide on how to do it:
First, you need to check whether your theme has this feature or not. Many Shopify themes, such as Dawn, Sense, Warehouse, Impulse, and Broadcast, include this feature by default.
To add the widget to your product page, follow these steps:
Step 1: Log into Shopify and go to the Sales Channels widget in the left sidebar.
Step 2: Click “Customize” next to your theme to open the Shopify Theme Editor.
Step 3: Use the dropdown menu at the top to select the default product page template.
Step 4: Check the left sidebar for the Related Products – Automatically suggested similar items, and then adjust settings if needed.
At this stage, the recommended products will be automatically generated by Shopify based on related items. However, you won’t have much control over which products are shown. If you want to manually choose specific products to be displayed in this section, proceed to Step 2.
To have more control over the recommended products, Shopify provides the Search & Discovery app, which allows you to manually select items that appear in the “Frequently Bought Together” widget.
By default, every Shopify store will have this app installed since this is an app developed by Shopify.
To customize your recommendations, follow these steps:
Step 1: Go to Search & Discovery > Recommendations, click Add Recommendations, and select a product. similar items, and then adjust settings if needed.
Step 2: Click Browse under Add complementary products and add up to 10 items.
Step 3: Click Browse under Related products, add up to 10 items, and check Hide auto-generated recommendations if needed.
Step 4: Click Save and View if needed.
However, this method only works with themes that support product recommendations. Moreover, like Shopify’s default settings, it doesn’t support discounts, making it better for basic recommendations rather than an advanced upselling strategy. Consider using a Shopify “frequently bought together” app if you need more advanced features ( I’ll take you through it now!).
The method above allows you to show product recommendations, but it has many limitations. Most importantly, Shopify does not allow you to create discounts for upselling products using its built-in theme features.
As we all know, discounts are a key factor in encouraging customers to buy more, as many shoppers are more likely to add extra items when they see a special offer. Hence, you may struggle to maximize your upsell potential without being able to apply discounts.
If you want full control over the FBT widget, using an app like BOGOS Free Gift & Bundle is the best solution.
BOGOS.io lets you manually select products, apply discounts, customize the widget design, and track performance. Here’s how you can set up an FBT section using this app.
Step 1: Choose an Upsell Offer Type
Step 2: Set Up the Upsell Information
Step 3: Choose an Upsell Trigger
You can control where the FBT section appears:
Step 4: Select an Upsell Method
There are 3 ways to select the recommended products:
Step 5: Enable Discounts (Optional)
Step 6: Preview and Publish
Step 7: Customize the FBT Widget

A well-optimized Shopify “Frequently Bought Together” (FBT) widget isn’t just about adding products—it’s about showing relevant recommendations that make sense to the customer. When items naturally complement a purchase, shoppers are more likely to buy more.
Amazon is a prime example. Its data-driven “item-to-item collaborative filtering” analyzes user behavior to suggest relevant products, leading to a 29% sales increase in one quarter, from $9.9B to $12.83B. (Source)
For Shopify merchants, the takeaway is clear: relevance matters. Don’t group random items. Instead, use real customer data to pair products that shoppers actually buy together, like cameras with memory cards and bags. Optimize based on sales trends to make your FBT widget truly effective.
Where you display the FBT widget affects how often customers engage with it. The best spot is usually below the product description on the product page since that’s when customers are considering their purchase.
You can also test showing FBT recommendations on the cart page, especially for last-minute upsells before checkout. Avoid placing it too low where visitors might not see it, and make sure it doesn’t clutter the page.
Use high-quality images, clear product names, and a layout that matches your store’s theme. Display the total price before and after discounts to emphasize savings. Buttons like “Add Selected Items” should be bold and visible. Shopify merchants who personalize their FBT widget – matching fonts, colors, and spacing – tend to see higher engagement and conversion rates.
Recently, mobile-friendly design has become vital because smartphones deliver 78% of retail site traffic and 68% of online orders (Statista, Q4 2024). To prevent the page from becoming excessively long, a carousel layout with scroll functionality should replace vertical stacking. Ease of tapping buttons should complement fast and efficient image loading. Shopify themes typically perform well on mobile screens; however, you must examine a mobile preview through your app before making it live.
If customers aren’t noticing the FBT widget, it’s likely due to poor placement or weak visibility. Many stores place it too low on the page, making it easy to miss.
To fix this, position the FBT widget right below the product description or near the “Add to Cart” button for better visibility. A bold heading like Frequently Bought Together – Save 15% can grab attention and encourage clicks. Also, ensure the widget matches your store’s design but still stands out visually. For better engagement, consider using a pop-up version of the FBT offer when customers add an item to their cart.
A slow-loading page can cause customers to leave before they even see the FBT wdiget. The most common culprits are large images, excessive scripts, or unoptimized third-party apps.
To improve speed, compress images to reduce file sizes without sacrificing quality. Also, limit the number of upsell products in the FBT widget – 3 to 4 recommendations are enough. If you’re using an app for FBT, check its impact on page speed, as some apps can slow down your store. Shopify’s performance reports can help identify bottlenecks that may be affecting your page speed.
If customers see the FBT widget but aren’t adding products, it could be because the recommendations aren’t relevant or valuable enough.
A good FBT strategy pairs complementary products that make sense together, like a phone case with a smartphone or a charger with a laptop. Customers are also more likely to buy when they see clear savings, so show both the original and discounted prices to highlight the deal.
If possible, offer additional incentives like a limited-time discount or free shipping for bundled purchases. Sometimes, simply moving the FBT widget higher up on the product page can also improve conversions.
Shopify Frequently Bought Together might not be as effective for stores selling custom jewelry, engraved gifts, or made-to-order items. Since these products require individual customization, fixed product bundles may not appeal to customers.
Instead of a standard FBT widget, try offering related product suggestions that help customers explore similar styles or materials. Another alternative is a “Build Your Own Bundle” feature, where customers can select personalized items and receive a discount for buying multiple pieces. If your store sells fashion or accessories, a “Complete the Look” widget may work better than traditional FBT recommendations.
I hope you find this post helpful in setting up your “Frequently Bought Together” widget on Shopify to increase sales and make shopping easier for customers. A well-placed FBT widget with relevant products and incentives can boost conversions and improve customer experience. Choosing the right method and optimizing it for visibility and engagement will help maximize its impact on your store.
Yes, but it depends on your theme. Some Shopify themes support automatic product recommendations, but they are not customizable.
The best place is below the product description or above the Add to Cart button. You can also test showing it on the cart page for last-minute upsells.
The ideal number is 3-4 products. Too many options can overwhelm customers and reduce conversions.
Yes, if you use an upsell app with built-in analytics. Shopify’s default feature does not provide performance tracking.
BOGOS.io Free Gift is one of the best options because it allows manual product selection, discounts, and full customization.
