The Frequently Bought Together(FBT) widget uncovers items that customers often purchase in the same transaction—empowering you to present complementary products at exactly the right moment. FBT drives incremental revenue through cross-sell and up-sell opportunities on product detail pages, cart pages, and beyond.
Recommended Placements

1. Product Page: Show “Customers Also Bought” for the current item

2. Cart Page: Surface related accessories for items in cart

3. Homepage: Generic “Customers Also Bought” carousel for returning shoppers

​
How It Works

The algorithm analyzes customers’ purchase histories to find patterns of frequently bought products. It uses artificial intelligence techniques to find patterns, and then it gives recommendations that the customer intends to buy together
  1. Purchase Pattern & Association Rule Mining
    Analyzes historical order data to identify items frequently bought together.
  2. Collaborative Filtering
    Uses AI techniques to surface strong item-pair associations.

​
Supported Rule Types

You can scope FBT behavior at multiple levels, each of which can override the global settings:
  • Global (default for all placements)
  • Home Page
  • Product Page
  • Cart Page

​
Behavior for Non-Logged-In Users

  • With Session Activity:
    Displays FBT based on items added or viewed in the current session.
  • Brand-New Visitors:
    • Fallback Disabled: On the product page, users will find suggestions to help them get started with the product. If the user is on the home page, it will not show any suggestions because there is no browsing history.
    • Fallback Enabled: Shows fallback algorithm suggestions to mitigate cold-start. On the product page, users will see suggestions for getting started with the product. When the user is on the home page, there are no suggestions due to the absence of browsing history. Instead, products will be displayed from Fallback.

​
Behavior for Logged-In Users

  • Returning Customers:

  • Freshly Registered (No History):
    • Fallback Disabled: On the product page, users will find suggestions to help them get started with the product. If the user is on the home page, it will not show any suggestions because there is no browsing history.
    • Fallback Enabled: Fallback suggestions fill the widget, guiding new users. On the product page, users will see suggestions for getting started with the product.

When to Use FBT

  • Complementary Products: Recommend laptop bags, mice, or chargers alongside laptops.

Example Scenario

  1. A shopper views a leather armchair on your PDP.
  2. FBT detects that past buyers often also purchased a throw pillow, footrest, and side table.
  3. A “Frequently Bought Together” carousel appears beneath the product details—showing those complementary items.
