Can I Add Categories and Tags to WordPress Pages?

Yes, you can. Both Categories and Tags are “taxonomies” and they can help you sort your content. However, on a normal WordPress site, both Categories and Tags are only available for Posts. This means that you do not have any options to organize your Pages … unless you use a plugin such as PublishPress Taxonomies. I’ll show you how to add Categories to your WordPress Pages.

• Install the PublishPress Taxonomies plugin.
• Go to “PublishPress Taxonomies” and then “Taxonomies” in your WordPress admin area.
• Click “Edit” under “Categories”.
• Click the “Post Types” tab.
• Check the box for “Pages”.
• You may also want to check the box “Show content from all post types on archive page” so that your Posts and Pages are grouped together on the Category pages.
• You will now see that “Categories” are available under “Pages” in your WordPress admin menu.
• When you are editing a Page, you will see the “Categories” box in the right sidebar.
• You will also be able to add and remove Categories using the “Quick Edit” and “Bulk Edit” features.

How Many Levels of Sub-Categories Does WordPress Support?

There is no technical limit to how deep your nested categories can go. In an image you can see by clicking the link below, I’ve created 10 levels of categories. You can keep adding sub-category levels as deep as you wish.

The main limitation to consider will be the WordPress admin area which will start to look strained. In another you can see by clicking, I’ve added twenty levels. When I go to add “Level 21”, the “Parent Category” dropdown appears to be broken. Those extra levels appear on the main “Categories” screen, but each one is only displayed after a long row of hyphens. And when you try to add a category to a post, you may find that the lower levels are not easily visible inside the metabox. The reason that WordPress allows you to have an unlimited number of sub-categories is that these are simple database entries. The sub-categories are controlled by the parent column in the wp_term_taxonomy table. Adding more sub-categories will not slow your site down at all.

Finally, I’ll note that you can add multiple levels to any WordPress taxonomy. Go to the “Taxonomies” screen in PublishPress Taxonomies. When you click “Edit”, you’ll be able to change the settings for each taxonomy. You can control whether the taxonomy is organized in parent-child relationships.

What’s the Difference Between WordPress Categories and Tags?

The main difference between Categories and Tags is the ability to create levels of Categories. Categories are hierarchical, which means terms can be organized into a parent-child relationship. For example, you could have a Category called “Fruit”, and under this Category you could have categories called “Apples”, “Bananas”, “Grapes”, and “Peaches”. Tags are not hierarchical, which means there’s no relationship between them. You can still add the same words as Tags, but by default they can not have relationships. You can modify this using the Taxonomies screen in PublishPress Taxonomies.
