When you don’t assign a catergory to your post, it will automatically go to ‘uncategorized’. The ‘Uncategorized’ category is a generic category where WordPress that doesn’t have a specific category go. Oftentimes I’m annoyed that my posts go in here since it doesn’t help me connect to my readers and provide useful information to them.
One quick solution is to edit “Uncategorized” in Post>Categories. This is a great option if you only have one category and haven’t created a content yet. Another quick solution is to set the default category in Settings>Writing. But, what if you want multiple categories?
