To add upsell products in WordPress using WooCommerce, follow these steps:

1. Edit the Product:

• In your WordPress dashboard, go to Products > All Products.
• Select the product you want to edit.

2. Navigate to Product Data:

• Scroll down to the Product Data section.
• Click on the Linked Products tab.

3. Add Upsell Products:

• In the Upsells field, start typing the name of the product(s) you want to upsell.
• Select the products you want to recommend as upsells.
• Upsell products are those that you think the customer will want to buy in addition to the current product, typically a higher-value item or a complementary item.

4. Save Changes:

• After adding the upsell products, scroll up and click the Update button to save your changes.

5. Displaying Upsell Products on the Front-End:

• By default, WooCommerce will display upsell products on the product page in a section like “You may also like…” or “Related Products”, depending on your theme.
• If you want to customize how upsell products are shown, you can edit your theme files or use a page builder plugin to style them as desired.

6. Customize Upsell Product Display (Optional):

If you want to customize where or how the upsell products are displayed (e.g., different location on the page or in a custom style), you might need to add custom code or use a page builder plugin (like Elementor) for more control.

Here’s an example of custom code to change the position of upsell products on the single product page:

phpCopy coderemove_action( 'woocommerce_after_single_product_summary', 'woocommerce_upsell_display', 15 );
add_action( 'woocommerce_after_single_product_summary', 'woocommerce_upsell_display', 5 );

This code moves the upsells higher up on the page.

7. Use a Plugin for Enhanced Upsell Features (Optional):

There are plugins like WooCommerce Boost Sales or WooCommerce Customizer that provide more options for setting up and displaying upsells, including adding advanced logic, and customizing the upsell behavior.

By following these steps, you can easily add and manage upsell products on your WooCommerce store!
