How to categorize posts
- To categorize a post, view the post in editor mode and go to the right sidebar widget called Categories.
- To add a new category, click + Add New Category, and enter the category name.
Once you’ve created a category, it’ll show up as an option for all other posts of that type, i.e. Posts (news or blog), People, Places, Items or Events.
You may assign one post to multiple categories by checking multiple boxes. If you’re using categories for your posts, it’s best to assign every post to at least one category.
Editing categories or adding multiple categories at once
To edit or delete existing categories, view your site dashboard. In the left menu, select the content type (eg, News, People, Items, etc.) and select Categories. Then select the category you wish to edit or delete. Deleting a category will not delete any posts; it will just remove that category from any posts for which it has been selected.
From the Categories page you can also add new categories, which is especially useful if you want to add several categories at once. You only need to insert the category’s name; don’t worry about all the other fields.
Bulk categorizing posts
If you’ve already published some posts but are new to using categories, you can bulk edit your already-published posts to assign them categories. Before you begin, make sure your categories are created and ready to go! (See tutorial above.)
- Go to your site dashboard then select the content type (eg, Posts, People, Events, etc.)
By default, the posts page will show only 20 posts at a time. To show more posts on this page, click Screen Options at the top and change the number of items per page from 20 to 500. This update will be saved to your theme user settings, so you will only have to do this once.
- Check the boxes to the left of all the posts you want in a specific category
- From the Bulk Actions dropdown at the top of the page, select Edit, then click Apply
- Now a Categories box will appear; select the category/ies you wish to assign to the selected posts
- Click the blue Update button on the right side of the page
- Repeat steps one through four for each category
You can use this same process to un-categorize posts as well, which is particularly helpful if you have posts tagged as “uncategorized” (see note below).
Eliminating the “uncategorized” filter
When you publish a post, WordPress automatically tags it as “uncategorized” if no other categories are checked. As a result, if you forget to categorize a post before publishing it, “uncategorized” may appear in your list of filters for those posts.
The good news is that since filters appear only if they are populated, you can easily solve the problem by editing the uncategorized post(s) and de-selecting that tag. You can also remove the category from multiple posts at once by bulk editing, as described above.
Just remember: Checking a different category does not de-select “uncategorized”; it must be unchecked manually.
