In this video you will learn about Product Category and Tag in WooCommerce.
Managing Product Categories and Tags
Product categories are the primary way to group products with similar features. You can also add subcategories if desired.
For example, if you sell clothing, you might have “t-shirts”, “hoodies” and “pants” as categories.
What are product tags?
Product tags are another way to relate products to each other, next to product categories. Contrary to categories, there is no hierarchy in tags; so there are no “subtags.”
For example, if you sell clothing, and you have a lot of cat prints, you could make a tag for “cat.” Then add that tag to the menu or sidebar so cat lovers can easily find all t-shirts, hoodies, and pants with cat prints.
How to add/edit product tags
Tags can be added similarly to adding product categories and work in exactly the same way as post tags. See the WordPress.org Codex for more information.
The taxonomy is product_tag.
