We’ll create a couple WordPress categories now. The reason we need to create these will become evident in our next post. One of the powerful features of WordPress is categories. Categories allow you to segregate your posts into different topics. For example, if your site is about muscle cars, you might have a category for Mustang, one for Camaro, and so on. In the example above, I am creating a category for “WordPress”. Note that I entered the name as I want it to appear on my site. It this case, with proper capitalization. In the “Slug” box you would enter it in all lower case. This is how it will appear in URL links. They do not have to be the same values. For our muscle car example, you could title the category “Mustang” and make the slug “ford-mustang”. For now, enter your category name and slug and scroll to the bottom and click “Add New Category”. We’ll circle back to categories in a few more steps once it becomes clearer their use case. Once you’ve added a couple categories you will see them show up on the right side of the screen in a list (see picture below).
