How to Show Related Products on Squarespace Product Pages
Your product pages are doing most of the heavy lifting in your Squarespace store. They're where customers make the decision to buy — or not. And they're where you have the best opportunity to increase the value of that decision by showing them something else they'll want.
Squarespace doesn't make this easy by default. There's no native related products widget, no cross-sell feature, and no way to connect products to each other in a meaningful merchandising sense. Here's how to fix that.
Why Showing Related Products on Product Pages Works
The customer who lands on your product page is already interested. They searched, clicked, and arrived at a specific item. That intent is valuable — and it extends beyond the single product they're viewing.
A customer looking at a leather belt is probably building an outfit. A customer looking at a coffee grinder is probably also thinking about beans, filters, and a decent cup. Showing them related products meets them where they already are — it doesn't interrupt, it completes.
Studies across ecommerce platforms consistently show that customers who see related product suggestions spend 10 to 30 percent more per order than those who don't. The lever is real. The question is how to activate it on Squarespace.
What Squarespace Gives You by Default
Very little. Some Squarespace 7.1 themes show a "Related Products" section at the bottom of product pages, but this pulls from the same category — which often means showing products that compete with the one the customer is already viewing, rather than ones that complement it.
True related products — where you control the pairing, position, and presentation — requires a plugin.
How to Show Related Products With UpsellGrow
UpsellGrow gives you full control over which products appear alongside which, where they appear on the page, and how they look. Here's the full picture:
Three Types of Related Product Suggestions
Cross-sell: You manually select which products to suggest alongside each trigger product. Best when you know your catalog and have clear complementary pairs.
Frequently Bought Together: UpsellGrow analyses your order history and automatically surfaces the combinations your customers actually buy together. Updates as new orders come in.
Bundle: Instead of suggesting a separate product, you offer a curated package at a discount. Highest average order value impact of the three types.
Six Positions on the Product Page
UpsellGrow doesn't lock you into one placement. On the product page alone, you can position related products in six locations:
- Above the product title — catches the customer before they engage with the product details
- Below the product title — appears as they read the description
- Above Add to Cart — last thing they see before clicking
- Below Add to Cart — the most common high-converting position
- Bottom of page — catches customers who scroll the full page
- Popup on Add to Cart — fires when the customer clicks Add to Cart, highest-intent moment on the page
Full Design Control
The related products widget can be displayed as a vertical stack (one product per row) or a horizontal grid (up to four products per row, with an optional carousel). Six color pickers give you control over the background, card, text, and button colors. The widget is built to match your store's existing design — not to look like a generic plugin.
Which Position Should You Start With?
For most stores, "Below Add to Cart" is the best starting position. The customer has already decided they want the main product — they're in buying mode — and the related products appear right as they're completing that decision.
If your products have a higher price point, the popup on Add to Cart click can outperform the inline positions. The popup creates a deliberate moment of attention before the customer proceeds to checkout.
Test both positions with UpsellGrow's analytics and let the data guide you after two to three weeks.
Keeping It Clean
The most common mistake when adding related products is showing too many. More than three or four suggestions on a product page starts to feel cluttered — and clutter kills conversions. The related products section should feel like a helpful addition to the page, not a second catalog.
One offer, three products, one clear position. Start there. Measure. Expand once you have data.
