On your WordPress blog, you must assign every post to at least one category. There’s nothing you can do about this – it’s the way WordPress works.
For this reason, WordPress uses a default category called Uncategorized.
It’s not a particularly nice word, but the description fits the purpose because you’ve published a post and haven’t assigned it to a suitable category. Assigning it to a suitable category helps your readers find the content that interests them. If you end up with a ton of posts in Uncategorized your blog won’t make any sense and will deliver a poor user experience.
Apart from these issues, assigning your posts to Uncategorized makes you look like you don’t know what you’re doing and looks unprofessional on a business blog. Which isn’t good if you’re out to impress potential new clients.
It’s fair to say that some people won’t even notice.
Luckily, it’s easy to change the default category to something more appropriate so no posts ever get published in the Uncategorized category. In my case, most of the posts currently go into the WordPress category. So it makes sense to choose this one as the default.
How to Change the Default Post Category in WordPress
The simple three-step process goes like this:
1. Navigate to Settings > Writing.
2. Then choose an alternative category from the drop-down menu.
3. Hit Save Changes.
After you’ve made this change, all future posts will be assigned to the new default category upon publication. If your focus switches to another subject in a month or two, you can change the default category again.
