Amazon has trained shoppers to expect one thing on every product page: a “Frequently bought together” box suggesting the two or three items that pair with what they are viewing. It is one of the simplest ways to lift average order value, and you can add the same thing to your store. This guide shows how to set up frequently bought together in WooCommerce for free.
What the box actually does
It shows a small set of complementary products with a combined price and a single “Add all to cart” button. Instead of hoping shoppers browse to the matching item, you put it in front of them at the moment of intent: a case next to a phone, batteries next to a toy, a lens cloth next to a camera.
Does WooCommerce include this?
Only partly. WooCommerce has Upsells and Cross-sells, but they are scattered: upsells show lower on the product page, cross-sells appear only in the cart, and neither gives a one-click “add the whole set” bundle with a combined total. For the true Amazon-style box you add a plugin.
How to add it with a free plugin
The Frequent Bundles for WooCommerce plugin puts the bundle box directly on your product pages:
- Install and activate it.
- Edit a product and choose the items that pair well with it.
- The product page now shows a “Frequently bought together” box with a live combined total and an add-all button.
Shoppers add the whole set in one click, and your average order value climbs with no extra ad spend.
How to choose bundles that convert
- Pair by genuine use, not price. The best bundles are things a customer would really buy together.
- Keep it to two or three items. A long list dilutes the nudge.
- Bundle consumables. Refills, filters and batteries are easy add-ons that also bring people back.
- Copy what already sells together in your order history.
A small box, a big payoff
Frequently bought together is one of the highest-leverage changes you can make to a WooCommerce store: nothing to run, it uses stock you already hold, and every extra item in the cart is pure margin. Set it up once and it works on every visit.
