In WordPress, a taxonomy is a way of grouping and organizing content. It’s a classification system that helps structure your site’s content and improve navigation. While categories and tags are the default taxonomies in WordPress, you can also create custom taxonomies to suit your specific needs.

Key aspects of taxonomies:

Types: Taxonomies can be hierarchical (like categories) or non-hierarchical (like tags).

Custom Taxonomies: You can create custom taxonomies for specific content types or organizational needs.

Terms: Individual items within a taxonomy are called terms. For example, “Fiction” and “Non-fiction” could be terms in a “Genre” taxonomy.

Association: Taxonomies are typically associated with specific post types, including custom post types.

Examples of custom taxonomies:

  • “Cuisine” for a food blog
  • “Location” for a travel website
  • “Skill Level” for a tutorial site

To create a custom taxonomy, you can use a plugin like Custom Post Type UI or add code to your theme’s functions.php file.
