Introduction
In today’s competitive eCommerce environment, simply listing products isn’t enough to grow your sales. To maximize profit margins and improve customer experience, online store owners must find effective ways to increase the average order value (AOV). One of the most efficient strategies is to offer WooCommerce addon products on product pages.
This guide will walk you through how to implement this on your WordPress WooCommerce store using a free plugin, so you can start increasing your sales without coding or expensive tools.
What Are WooCommerce Addon Products?
WooCommerce addon products are complementary or related items displayed alongside a primary product on a product page. These could be accessories, product bundles, or frequently purchased items.
Examples include:
A laptop sleeve offered alongside a laptop
Batteries listed with electronic gadgets
A leash added with a dog collar
By showing relevant products at the right time, you improve user convenience and boost your store’s conversion rates.
