How To Configure Categories In WordPressWordPress categories help make finding information about similar topics on your site easier for visitors. Publishing posts under categories not only helps to keep your content organized, it also improves both your visitor’s search experience and your search engine rankings.

In this step-by-step tutorial, you will learn about using WordPress categories.

Using WordPress Post Categories

Step 1: Configuring Permalinks

By default, WordPress post URLs are not 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 WordPress to display SEO-friendly URLs, so instead of having a web address that looks like this:

The post URL can look like this:

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

Step 2: Create A List Of 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 looking for, but can also help search engines to better index your content.

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


If you need help planning a website, go here: The Web Site Planning Process Explained - A Money-Saving Guide For Business Owners

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

Let’s say, for example, that you want to start a website or blog 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 Planning
  • Commitment Ceremonies
  • and so on …

Step 3: Select Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Business”, etc…) is extremely hard, especially when you’re just starting out. you have a better chance of getting somewhere by focusing on establishing your authority in a niche, or a subset of your market.

Take a look at the illustration 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 deciding on the keywords you would use as a top-level category to file your posts under, it’s a good idea to consider factors like “market competition.”

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

Google Keyword Planner - Useful keyword research tool for category planning

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

When planning your category topics, it’s important to take your time and think 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 to a competitive advantage. If you set an unrealistic goal (i.e. dominating the entire “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 grow your business online.

For tutorials on strategic online business areas like effective keyword research, identifying target audience demographics, etc., refer to this tutorial: A Comprehensive Guide To Web Site Planning For Business Owners

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

Step 4: Set Up WordPress Post Categories

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

WordPress lets you easily organize content by categories

(Organize your posts with categories)

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

(Categories screen – Add New Category)

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

Categories panel - Add New Category fields

(WordPress Post Categories screen – Add New Category fields)

  1. Name – Type 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” are 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 the category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website.
  4. Description – Write 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 your category pages “meta” description.

If you need help creating or editing posts in WordPress, see the tutorials below:

Deleting WordPress Categories


Removing a category does not delete the posts assigned to that category. Instead, posts 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 categories individually, hover over the category you want removed and click the ‘Delete’ link …

Category table - Delete link

(Deleting a single category)

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

Click 'OK' to delete the category

(Click ‘OK’ to delete the category)

Deleting WordPress Categories In Bulk

Let’s say that you import product data into your WordPress site containing a large number of categories (e.g. an e-commerce catalog), and you want to reduce the number of categories by assigning your imported posts to a fewer number of categories. 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 may be affected when unnecessary categories are deleted have been reassigned to an existing or new category. For more details on reassigning post categories, go to this tutorial: Editing And Deleting A Post In WordPress

To delete multiple WordPress categories, click the main checkbox next to the ‘Name’ column title. This will select all category items .

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

Editing Categories In WordPress

To edit a WordPress post category, do this:

Go to your ‘Categories’ table, locate the category entry that needs editing, then place your mouse over the category title, and click Edit

Edit - WordPress post category menu

(Category table menu – Edit)

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

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

Quick Edit link

(Category table – Quick Edit)

Edit your details and click on the ‘Update Category’ button to save your changes …

Quick Edit screen

(Category – Quick Edit fields)


Modifying the category slug will change the URL of all posts assigned to that category. This can lead to “page not found” errors when visitors click on links to posts published elsewhere.

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 Categories – Useful Tip

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

WordPress category - 'Uncategorized'

(WordPress category – ‘Uncategorized’)

Useful Information

The default category cannot be deleted.

Having posts assigned 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 posts as “uncategorized”, let’s make the category a little more relevant to your site readers and optimize it better for search engines too.

Place your mouse over the “Uncategorized” entry and click on Quick Edit

Category: Uncategorized - Quick Edit Link

(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 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 …

Change 'Uncategorized' category to something more meaningful to your visitors and search engines

(Change ‘Uncategorized’ category to something more meaningful to your readers and search engines)
