Add, Edit & Delete WordPress CategoriesWordPress categories can help to make finding information about similar topics on your site easier for visitors. Publishing posts under categories also helps search engines to better index your WordPress site.

Learn about adding, editing & deleting categories in WordPress in this tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Default WordPress post web addresses are not very search engine friendly. In order to make the best use of categories, you will need to modify the way WordPress displays your URLs.

Permalinks allow your WordPress site to display SEO-friendly URLs, so instead of having a web address that looks like this:

You can have the post URL display like this:

If you have not configured your permalinks yet, then do so first before configuring your categories.

To learn more about permalinks, refer to this tutorial: How To Improve Your WordPress SEO With Permalinks

Step 2: Create A List Of Topics

Keeping your site’s content organized is important, as this will not only make it easier for your visitors to find the information they’re searching for, but can also help search engines to better index your content.

The first step, then, is to carefully plan what kind of broad “topics” you will be publishing on your website or blog. These can be topics related to your niche, your services or products, your industry, etc.

When creating a list of topics, remember to include areas of your business that your visitors, prospects, and clients need to be better educated or informed about. This is important in terms of establishing your business as an “authority” that online visitors will want to come back repeatedly to and/or refer to others.

Let’s say, for example, that you would like to start a site to promote your marriage celebrant business. After a little brainstorming, some of the broad topics (i.e. categories) you may expect to see on an authoritative wedding celebrant’s site could include the following:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Planning
  • Commitment Ceremonies
  • etc.

Step 3: Choose Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is extremely difficult, especially when you’re just starting out. It’s better to try and build your authority in a niche, or a segment of your main market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see from the above Market > Niche > Subniche hierarchy that “Marriage Celebrant Course” is a subniche (i.e. a subcategory) of the “Marriage Celebrant” niche (a category), which itself is a subcategory of the larger “Weddings” market (another category).

When selecting the keywords you would use as a top-level category to file your posts under, it’s a good idea to take into account factors like “market competition.”

For example, the screenshot below shows Google’s estimates for the average number of monthly searches for each of the above keywords …

Google Keyword Planner - Keyword research for category planning

(Use keyword research tools to help with category planning)

When planning your category titles, it’s important to spend time thinking carefully about all the elements you can control (like the main keywords used throughout your content), and how you are going to use these elements to try and gain a competitive advantage. If you set a goal that is too big (i.e. trying to dominate the “Wedding” market), you will only end up feeling disappointed. If, on the other hand, you focus on a narrow niche or microniche, you could experience little to no activity on your site and hence no significant opportunities to increase your market share online.

For tutorials on online business areas like effective keyword research, identifying audience demographics, etc., see this tutorial: How To Plan Your Business Web Site: A Basic Primer For Non-Technical Business Owners

Once you have mapped out your top-level topics and figured out what your main keywords are, the next step is to convert these keywords into post categories.

Step 4: Set Up Your Post Categories

Saving posts under carefully planned categories helps to keep your content organized, provides site visitors with a better user experience, and helps to optimize your web pages for search engines.

WordPress allows you to easily organize content using categories

(Organize posts with categories)

To access your WordPress Categories section, in the Dashboard menu, click on Posts > Categories

Posts - Categories

(Posts – Categories)

This opens the ‘Categories’ panel …

(Post Categories Screen)

In this section, you can create, edit, and delete categories, including inserting descriptions for categories and other information that can optimize your website for search engines.

(Categories screen – Add New Category)

To add a new category, simply fill in the fields in the ‘Add New Category’ area as shown in the example below:

WP Post Categories screen - Add New Category fields

(WordPress Post Categories screen – Add New Category fields)

  1. Name – Type a short category name here, preferably using your main keyword (e.g. if you have a “Travel” related blog, you could have categories like “Travel Tips”, “Travel Destinations”, etc …). Your category names will then display in all the category-related sections of your website.
  2. Slug – The “slug” refers to the words that display in the URL of all posts published under a category. The slug can be different from the category name. Note: Keep all words lower case and make sure they only contain letters, number and hyphens (i.e. no spaces between words). If you don’t enter a slug into this field, WordPress will automatically create one for you using a lower case version of your category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website (explained further below).
  4. Description – Add a brief category description here. Some WordPress themes display this category description, and it can help with SEO. WordPress uses the category description you write here for the category pages “meta” description.

Click the ‘Add New Category’ button when done to add your new category …

How To Remove Categories


Deleting a category does not delete posts assigned to that category. Instead, any posts that were assigned to deleted categories will be reassigned to the default category (see further below).

You can delete WordPress categories individually, or in bulk.

How To Delete Single Categories

To delete categories individually, place your mouse over the category you would like to delete and click the ‘Delete’ link …

Deleting single categories

(WordPress category menu – Delete)

A warning message will pop up in your browser asking you to confirm the deletion. Click OK to permanently delete the item, or Cancel to abort …

Click 'OK' to proceed

(Click ‘OK’ to delete the category)

How To Delete Categories In Bulk

Let’s say that you import product data into your WordPress site containing many different categories (e.g. an e-commerce catalog), and you want to reduce the number of categories by assigning your imported posts to a single category. If you have too many categories to delete one at a time, this is where the bulk delete feature comes in handy.


Important: Make sure that any posts that may be affected when categories are removed have been reassigned to an existing or new category. For more details on how to reassign categories in posts, go to this tutorial: Editing And Deleting WordPress Posts

To delete multiple categories, click the main check box next to the ‘Name’ column title. This will select all category entries on the page.

Next, go through the list and untick the box next to any categories that you DO NOT want to delete. You can select/deselect categories by toggling on the checkbox next to the item.

Editing Categories

To edit a category in WordPress, do this:

Go to your ‘Categories’ section, locate the item to be edited, then hover over the category title, and click Edit

Edit link - Category table menu


This brings up the ‘Edit Category’ section. Edit the category fields, and click Update to save your details …

'Edit Category' panel

(‘Edit Category’ panel)

You can also edit categories using the Quick Edit option. Place your mouse over the category title you want to edit and click the ‘Quick Edit’ link …

Quick Edit

(WordPress post category table menu – Quick Edit link)

Edit your details and click Update Category to save your changes …

Category - Quick Edit fields

(Quick Edit screen)


Modifying the category slug affects the URL of all posts published under that category. This can lead to “page not found” errors when visitors click on links pointing to posts that have already been indexed by search engines.

For this reason, we recommend investing time into planning your categories before publishing content, and avoid changing the category slug afterward if at all possible, especially after your posts and pages have already been indexed in the search engines.

WordPress Post Categories – Special Tip

All posts must be assigned to categories in WordPress. If you do not assign a post to a category, WordPress will automatically assign your post to the default category “Uncategorized” …

Category - 'Uncategorized'

(’Uncategorized’ WordPress category)

Useful Info

The default category cannot be deleted.

Attributing posts to a category named ‘Uncategorized’ not only creates unattractive URLs, but URLs that are not very effective in terms of helping your site’s SEO (Search Engine Optimization)…

Publishing posts under the 'uncategorized' category is not recommended

(Publishing posts under the ‘uncategorized’ category is not recommended)

Instead of publishing unassigned posts as “uncategorized”, let’s make the category a little more meaningful to your visitors and optimize it better for search engines too.

Place your mouse over the “Uncategorized” entry and click on the ‘Quick Edit’ link …

Category: Uncategorized - Quick Edit

(Quick Edit)

Change the Category Name and Category Slug to a keyword or keyword phrase that will be generally relevant to the overall topic of your site. For example, in the example below the site is about travel, so you could change the “Uncategorized” category to “Travel Tips” in order to give your site a little extra SEO boost …
