Hello @laurpm,
Thank you for reaching out to us.
If you wish to apply those variables to all the product’s meta description, you can simply add them in the meta description field in your Titles & Meta settings which you can see in Rank Math > Titles & Meta > Products. This should be applied as the default meta description.
Please note that this is the order we follow to generate meta descriptions for WooCommerce products or product categories for that matter:
- Content from SEO Description field
If that is missing, then:
- WooCommerce Excerpt or Product Short Description
If that is missing, then:
- Template From General Settings in WordPress Dashboard > Rank Math > Titles & Meta > Products
If that is missing, then:
- Auto-generated Content from the product page.
Hope that helps and please do not hesitate to let us know if you need my assistance with anything else.
