Some things you must be aware of before we start:

  • While I am well-versed in PHP, I am just starting to learn to use it in a WooCommerce-specific way.
  • I am using a child theme (the default Storefront theme with minimal customization) in a development/testing environment.
  • I am placing all customization PHP code in the child theme functions.php file in order for theme updates to not overwrite and remove said changes.
  • I am using Local by Flywheel for local WordPress development and absolutely love it!
Backstory and article inspiration

I’ve been searching and reading in WooCommerce Facebook groups, specific requests shop owners are asking about in those forums and attempting to implement them in a mock setup environment. This practice helps me better prepare for real-world scenario’s.

I saw one such recent post inquiring about how to change the ‘Related products‘ heading description to something else entirely. I learned about 2 different ways to accomplish this.


I don’t necessarily know or can say that either of these solutions is the best practice for localization (language translation). Keep that in mind.

WooCommerce Single Product page default verbiage

If there are some related products then by default, for that section of the Single Product page, we have the “Related products” wording:

This might be a little bland for your tastes and can easily be changed to some other wording or phrase.

WooCommerce edit default Related products description: Use add_filter() hook

Using an add_filter() hook, you can target the woocommerce_product_related_products_heading hook, implementing your own callback function and return value:

WooCommerce edit default Related products description: Edit child theme template file

In your_child_theme/woocommerce/single-product/related.php file, change the $heading variable in the if( $related_products ) conditional:

Note: If you use this option, you are now responsible for updating the copy of this theme template file in your child theme should any updates be applied to the parent theme template file.

All that said, this is not likely the best solution for maintainability reasons.

But, it does work.
