Add a category
- Log in to your WordPress dashboard at
https://yourdomain.com/wp-admin. See how to log in to WordPress. - Go to Posts › Categories.
- Enter a Name. The slug (the web address) is created for you.
- Optionally choose a Parent Category to create a sub-category.
- Click Add New Category.
Delete a category
On Posts › Categories, hover over the category and click Delete. Posts in it aren’t deleted; any that have no other category move to the default category.
Get rid of “Uncategorized”
WordPress always needs a default category, so “Uncategorized” can’t be deleted while it’s the default. Either:
- Rename it: hover over it on Posts › Categories, click Edit, change the name and slug (for example to “News”) and click Update. Or
- Choose a different default: go to Settings › Writing, pick another Default Post Category, click Save Changes, then delete “Uncategorized”.
