Frequently bought together
The Frequently Bought Together logic analyzes what other shoppers have concurrently added to their cart with a specific product. This makes it exceptionally effective for boosting the attach rate of accessories, refills, and complementary items.

How it works
- Identifies co-occurrence patterns in add-to-cart behavior, indicating a stronger purchase intent compared to mere product views.
- Recommendations are anchored to the product currently being displayed on the product page.
- On cart templates, relevant collaborative cart logics can also be applied, subject to specific configuration settings.
Best placements
Product Detail Pages (PDPs)
A classic 'Frequently Bought Together' (FBT) or attachment merchandising placement, typically below the buy box.

Effectively reinforces the suggestion of complementary items just before the checkout process.
Things to know
- Requires a sufficient volume of cart events. New or 'cold' catalogs may initially show limited results.
- Differs from cart cross-sell, which considers the entire current cart content. This logic focuses on co-occurrence with a single anchor product.
- Utilizing filters helps ensure that suggested attachments remain relevant and within appropriate collections.
