How to Add a 'Customers Also Bought' Section on Squarespace
If you've ever shopped on Amazon, you've seen it: "Customers who bought this item also bought..." followed by a tight row of genuinely useful product suggestions. It works because it reflects real purchasing behavior — not a guess. And it sells.
Squarespace doesn't include a "Customers Also Bought" section. But you can add one — and it takes less time than you might expect. Here's how.
Why 'Customers Also Bought' Is Different From 'Related Products'
Most people use these terms interchangeably, but they mean different things in practice.
Related products are manually curated. You decide which products appear alongside which. This works well when you know your catalog and your customers well.
Customers also bought (or Frequently Bought Together) is data-driven. The system analyses your actual order history and surfaces products that appear together in completed purchases. No guessing. No curation. Just your customers' real behavior reflected back to new shoppers.
The reason this converts so well is trust. When a suggestion is based on what other people actually bought, it carries a social proof element that a manually curated suggestion doesn't.
Does Squarespace Support This Natively?
No. Squarespace 7.1 has no "Customers Also Bought" feature. There's no order-history analysis, no FBT algorithm, and no native cross-sell widget. To get this on your store, you need a plugin.
How to Add 'Customers Also Bought' With UpsellGrow
UpsellGrow includes a Frequently Bought Together offer type that works exactly like this. It analyses your Squarespace order history, identifies which products are most commonly purchased together, and displays those pairings automatically on your product pages.
Setup Process
Install UpsellGrow on your Squarespace 7.1 store. It works as a native block — no code required.
Create a new FBT offer. In the dashboard, select "New Offer," choose "Product Page" as the location, and select "Frequently Bought Together" as the type.
Select trigger products. You can apply the FBT offer to specific products, or set it to run across your entire catalog.
Set the position. "Below Add to Cart" is typically the strongest performing position for FBT sections. You can also use a popup that fires when the customer clicks Add to Cart.
Customize the widget. Set the heading text to "Customers Also Bought," "Others Also Bought," "Frequently Bought Together," or any label that fits your store. Match the design to your existing product page layout.
Publish. UpsellGrow begins pulling from your order history immediately and updates the suggestions automatically as new orders come in.
What if You Don't Have Enough Order History?
FBT needs data to work. If your store is relatively new or has a small number of orders, UpsellGrow lets you set a fallback — a manually curated cross-sell that displays instead until the FBT data becomes meaningful. This means you're never showing an empty section.
Where Else Can It Appear?
UpsellGrow doesn't limit "Customers Also Bought" suggestions to the product page. You can show FBT offers in the slide-out cart, on the cart page, and on the order confirmation page. Each additional touchpoint multiplies the opportunity.
How Much Does It Increase Sales?
The impact varies by store, product type, and how well-configured the suggestions are. Generally, stores that add FBT see 15 to 30 percent increases in average order value within the first month. The benefit compounds over time as the data improves.
The reason is simple: when customers see a suggestion that reflects what people like them actually bought, they trust it. That trust converts to sales.
Getting the Most Out of 'Customers Also Bought'
Let it run for a few weeks before judging performance. The suggestions get more accurate as more order data accumulates. Early results may be modest. Give it time.
Combine with cross-sells for new products. New products don't have order history. Use a manual cross-sell for new arrivals and let FBT handle your established catalog.
Check the analytics regularly. UpsellGrow shows impressions, conversions, and revenue for every offer. If a pairing isn't converting, look at whether the products are genuinely complementary — or whether the position on the page needs adjusting.
