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 …

How To Set Up WP Post CategoriesWordPress categories help to make finding information on your site easier for visitors. Categories also help to keep you content organized and allow search engines to better index your WordPress site.

Learn about using WordPress categories in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Out of the box, WordPress post URLs aren’t really 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 your WordPress site to display SEO-friendly URLs, so instead of having a post link that looks like this:

You can have the same post URL display like this:

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

We have written a detailed tutorial about setting up and using permalinks here: Using Permalinks To Improve Your WordPress SEO

Step 2: List Your Topics

Keeping your content organized is very 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 improved search results.

The first step, then, is to plan what kind of broad “topics” you will publish on your site. These can be topics related to your niche, your business, and even your industry.


We have written a detailed tutorial on website planning here: Planning Your Business Web Site - A Basic Primer For Non-Technical 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 web site as an “authority” that online visitors will want to subscribe to (if you offer a newsletter or valuable content like ongoing training, tips, etc.) and/or refer to others.

For example, let’s say 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:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Locations
  • Marriage Vows
  • and so on …

Step 3: Choose Relevant Category Titles

Dominating an entire market (i.e. “Weddings”, “Travel”, “Technology”, etc…) is extremely difficult, especially when you’re just getting started. you have a better chance of getting somewhere by trying to establish your authority in a niche, or segment (i.e. subniche) 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 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 publish your posts under, it’s a good idea to take into account factors like “market competition.”

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

Use keyword research tools to help with category planning

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

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

After mapping out your top-level topics and figuring out what your main keywords are, the next step is to turn your keywords into post categories.

Step 4: Set Up WP Categories

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

WordPress lets you easily organize your posts with categories

(WordPress allows you to easily organize content using categories)

(WP Post Categories panel – Add New Category fields)

  1. Name – Type a short category name here, preferably one that uses 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. Your slug can be different from your 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 your category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website.
  4. Description – Add a brief description of your category here. Some WordPress themes display this category description, and it can help with SEO. Your category description will be used for the category pages “meta” description.

Deleting Post Categories


Deleting a category does not delete posts assigned to that category. Instead, posts assigned to the deleted category will be reassigned to the default category (this is covered further below).

You can delete categories individually, or in bulk.

How To Delete An Individual Category

To remove single categories, place your mouse over the category and click Delete

WordPress post category - Delete link

(How to delete a single category)

A message will appear 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 site containing many different categories (e.g. an e-commerce catalog), and you want to reduce the number of existing categories by assigning your imported posts to a fewer number of categories. If there are too many categories to delete one at a time, this is where the bulk delete feature can be useful.


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 reassigning categories in posts, see this tutorial: How To Edit And Delete Posts

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

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

After selecting all of the items to be deleted, choose ‘Delete’ from the ‘Bulk Actions’ drop menu …

How To Edit Post Categories

To edit a category, do this:

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

Category - Edit link

(Category table menu – Edit link)

This brings up the ‘Edit Category’ panel. Make changes to the information in the category fields, and click Update to save the changes …

You can also edit information in categories using the Quick Edit option. Hover over the category title you want to edit and click on Quick Edit

Quick Edit - Category table

(WordPress post category – Quick Edit)

(Category table menu – Quick Edit fields)


Important: Modifying the category slug changes the URL of all 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, it’s best to invest time into planning your categories before publishing content, and avoid changing the post category slug afterward if at all possible, especially after your site is established.

WordPress Post Categories – Useful 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 a default category called “Uncategorized” …

WordPress post category - 'Uncategorized'

(WordPress category – ‘Uncategorized’)


The default category cannot be deleted.

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

Hover over the “Uncategorized” entry and click on the ‘Quick Edit’ link …

Quick Edit

(Category table menu: Uncategorized – Quick Edit link)

Change both 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” to give your site a little extra SEO boost …
