Using WordPress Post Categories

Learn what categories are, how to use categories to improve your content navigation and SEO, and how to add, edit, and delete WordPress categories.

Adding, Editing & Deleting Post Categories In WordPressWordPress categories can help make finding information on your site easier for visitors. Filing posts under categories also helps to keep you content organized and allows search engines to better index your WordPress site.

In this step-by-step tutorial, you will learn how to configure post categories.

Using WordPress Post Categories

Step 1: Configuring Permalinks

By default, WordPress URLs aren’t very search engine friendly. In order to make the best use of WordPress categories, you will first need to modify the way WordPress displays your URLs.

Permalinks allow WordPress to display search engine friendly URLs, so instead of having a web address that looks like this:

The same post URL can display like this:

If you have not configured your permalinks yet, then we recommend doing so now before configuring your post categories.

We have created a detailed tutorial on configuring permalinks here: How To Change Your WordPress 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 to significantly boost your site’s optimization for better search results.

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


We have written a detailed tutorial on website planning here: How To Plan Your Website - A Money-Saving Blueprint For Business Owners

When creating a list of topics, remember to include areas of your business that you believe your visitors, prospects, and clients need to be better educated or informed about. This is very important in terms of establishing your business as an online authority that visitors will want to subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer to others.

For example, let’s say that you want 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 Tips
  • Marriage Vows
  • etc.

Step 3: Select Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Sports”, etc…) is very hard to do, especially if you’re just getting started. you have a better chance of getting somewhere by focusing on building your authority in a niche, or segment of your main market.

Take a look at the illustration below …

How To Add, Edit And Delete WordPress Categories

You can see from the above Market > Niche > Sub niche hierarchy that “Marriage Celebrant Course” is a sub niche (i.e. a subcategory) of the “Marriage Celebrant” niche (a category), which itself is a subcategory of the “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 sample keywords …

Keyword research can help you with category planning

(Google Keyword Planner – Useful keyword research tool for category planning)

When planning your topic categories, it’s important to take your time and think carefully about all the elements you have control over (like the keywords that will be used throughout your site), and how you are going to use these elements to try and gain a competitive advantage. If you set a strategic objective that is too big (i.e. aiming to dominate the entire “Wedding” market), you will only end up feeling disappointed. If, on the other hand, you focus on a very narrow niche or microniche, you could experience little to no activity on your site and hence no significant opportunities to increase your business online.

If you need help with online business online strategies like keyword research, identifying target audience demographics, etc., see this tutorial: A Money-Saving Guide To Web Site Planning 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 WP Categories

Saving posts under carefully planned categories that relate to the main topics of your site helps keep your content organized and easy to find, provides site visitors with a better user experience, and helps to optimize your content for search engines.

Organize your posts with categories

(Organize your content by categories)

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

(WP Post Categories panel – Add New Category)

To create a new post category in WordPress, complete the fields in the ‘Add New Category’ section as per the example shown below:

Categories screen - Add New Category fields

(Post Categories screen – Add New Category fields)

  1. Name – Enter a concise 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 display in all 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 specific 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 create one for you automatically using a lower case version of the category name.
  3. Parent – Ignore this field, unless you plan to create nested category hierarchies on your website.
  4. Description – Write a brief description of your category here. Some WordPress themes display this category description, and it can help with search engine optimization. WordPress uses the category description you write here for your category pages “meta” description.

Removing Categories


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

You can delete categories individually, or in bulk.

Deleting Categories Individually

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

Delete link - Category table menu

(Delete link)

A warning message will appear in your browser asking you to confirm the deletion. Click OK to proceed, or Cancel to abort …

Click 'OK' to proceed

(Click ‘OK’ to proceed)

How To Delete WordPress Categories In Bulk

Let’s say that you import product data into your site containing a large number of categories (e.g. an e-commerce catalog), and you would like to consolidate posts to a single category. If there are too many categories to delete individually, this is where the bulk delete feature comes in handy.


Important: Make sure that any posts that will be affected by deleting unwanted categories have been reassigned to an existing or new category. For more details on how to reassign categories in posts, go to this tutorial: How To Edit And Delete A WordPress Post

To delete multiple categories, click the main checkbox in the header row. This will select all category entries on the page.

Next, go through the table and untick the box next to 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 WordPress post category, do this:

In your ‘Categories’ table, locate the category entry to be edited, then place your mouse over the category name, and click the ‘Edit’ link …

Edit - Category

(Category table menu – Edit link)

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

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

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

Post Category – 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 “Uncategorized” …

'Uncategorized' post category

(’Uncategorized’ post category)

Important Info

The default category cannot be deleted.

Publishing posts under the ‘Uncategorized’ category 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 posts as “uncategorized”, let’s make the category a little more relevant to your site readers and optimized for search engines too.

Hover over the “Uncategorized” entry and click on Quick Edit

Quick Edit Link

(Category menu: Uncategorized – Quick Edit link)

Change the Category Name and Category Slug to a keyword or keyword phrase that will be generally relevant to the main 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 an extra SEO boost …
