How to Convert WordPress Categories to Custom Taxonomies

Next, simply add the IDs for all the categories that you want to convert into a specific taxonomy. Keep in mind that if you add more than one category ID, then you will have to separate them using commas.

Type category IDs in the field

Note: AIOSEO also has a free version. However, you will need the pro version for this tutorial to unlock the 301 redirection feature.

This means that we will be converting a category into a custom taxonomy.

Choose categories option from the Taxonomy to switch from dropdown menu

Now visit your WordPress block editor by opening up a new or existing post/page.

However, if you want to skip the child categories, then you can type the parent category next to the ‘Limit taxonomy switch for child terms of a specific parent’ option. This way, only the parent category will be switched to a taxonomy.

Finally, click the ‘Add Redirect’ button in the right corner.

Choose 301 as the redirect type

As your WordPress blog grows, you might need to convert your categories into a custom taxonomy because it can be overwhelming to file and keep track of each post in a category with different subcategories.

The category edit URL will now appear in a popup box at the bottom left corner of your screen.

Here, you will notice that the category you switched to taxonomy is now displayed in the block panel on the right corner of the screen. From here, you can now easily add new terms or use existing ones for your WordPress blog post.

How to Set Up Redirects From Category to Custom Taxonomy

Using custom taxonomies for tagging allows for more accurate and detailed classifications and better content organization.

However, by creating a custom taxonomy for each of these topics, you can make content organization easier.

Some of the categories in WordPress also have subcategories (child categories).

Next, make sure that ‘301 Moved Permanently’ is chosen as the redirect option from the dropdown menu.

If you want to convert all the categories on your WordPress site into this specific custom taxonomy, then simply click the ‘Switch Taxonomies’ button.

In this article, we will show you how to easily convert WordPress categories to custom taxonomies.

Converting WordPress categories to custom taxonomies

Why and When Do You Need to Convert Categories into Custom Taxonomies?

You will now see the taxonomy that you have created along with the default taxonomies in the Posts menu tab in the WordPress sidebar.

The Redirects page will now be displayed on your screen.

This redirect will now send all your category archive traffic to your custom taxonomy.

However, we recommend using this method only if you don’t want to use categories at all.

First, you will need to install and activate the Taxonomy Switcher plugin. For more detailed instructions, you may want to see our step-by-step guide on how to install a WordPress plugin.

Upon clicking on the custom taxonomy, you will be taken to a new page, where you can easily add terms for the taxonomy by typing in a name and slug.

Add a term to the dietary restrictions taxonomy

However, if your website is live, then search engines may have already crawled your category pages and indexed them. This means that those pages can appear in search results, and users coming from search engines will see a 404 error page.

For example, if you have a category for dietary restrictions and you want to switch to a taxonomy of the same name, then you can select the ‘Dietary Restrictions’ option from the dropdown menu.

Once you do that, click the gear icon in the field to open some additional settings for the source URL. From here, check the ‘Regex’ option.

A taxonomy allows you to organize groups of posts and custom post types on your WordPress website. By default, WordPress comes with two pre-made taxonomies: categories and tags.

To find a category id, you will need to visit the Posts » Categories page from the WordPress dashboard and hover your mouse over the category of your choice.

After that, enter your custom taxonomy slug, e.g. /dietary_restrictions/1 into the ‘Target URL’ field.

Add the source and target URL

Once you are there, you need to select the ‘Categories’ option from the ‘Taxonomy to switch from’ dropdown menu.

From here, you can always toggle the switch to ‘Inactive’ if you want to disable it.

Disable the redirect by toggling the switch

Categories are one of the two default taxonomies that help you sort your content. WordPress also allows you to create and use custom taxonomies.

After you turn one of your categories into a custom taxonomy, the category archive page will now show a 404 error. This is nothing to be worried about if your website is not live yet.

Once you have done that, head over to the All in One SEO » Redirects page from the WordPress admin sidebar.

For example, if you have a recipe website, then creating categories for cuisine type, dietary restrictions, and meal type can be a bit confusing.
