Category is one of the default taxonomies in WordPress. You can use categories to sort and group Posts or People into different sections.
Categories help visitors quickly know what topics your website is about and allows them to navigate your site faster.
The default category in a new WordPress installation is “Uncategorized“. If you don’t pick a category for a post/person, it is automatically placed into the default category.
Types of categories
There are two types on most sites: Post Categories and People Categories.
