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.

Configuring WordPress CategoriesWordPress categories can help make finding information on your site easier for visitors. Adding post categories not only helps to organize your content, it also improves both your visitor’s experience and your search engine rankings.

This step-by-step tutorial helps you learn about adding, editing, and deleting categories in posts.

Using WordPress Post Categories

Step 1: Configuring Permalinks

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

Permalinks let you display search engine friendly URLs, so instead of having a post link that looks like this:

You can have the post URL display like this:

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

Step 2: Create A List Of Topics

Maintaining your site’s content organized at all times is 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.

We recommend, therefore, planning what kind of broad “topics” you will be writing about. These can be topics related to your niche, your business, your industry, etc.


We have written a detailed tutorial about website planning here: A Comprehensive Guide To Web Site Planning For Business Owners

When creating your 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 “authority” that online 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 website 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
  • and so on …

Step 3: Choose Relevant Category Headings

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Technology”, 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 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 in the above Market > Niche > Sub niche 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 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 online searches performed each month for each of these keywords …

Google Keyword Planner - Useful keyword research for category planning

(Keyword research - a useful tool for category planning)

When planning your 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 content), and how to use these elements to gain a competitive advantage. If you set too big a goal (i.e. dominating the entire online “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 business online.

If you need help with strategic online business planning like keyword research, identifying audience demographics, etc., refer to this tutorial: A Cost-Saving 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 turn your keywords into categories and add them to your WordPress site.

Step 4: Set Up Your Categories

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

Organize posts with categories

(WordPress allows you to easily organize content with categories)

To access your Categories section, log into your WordPress dashboard, then go to the admin navigation menu and click on Posts > Categories

Posts - Categories

(Posts – Categories)

This opens the ‘Categories’ screen …

Categories Area

(Post Categories Panel)

This section lets you create, edit, and remove categories, including inserting descriptions for categories and other information that can optimize your website or blog for search engines.

Adding Post Categories To WordPress

Categories screen - Add New Category

(Categories panel – Add New Category section)

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

Categories screen - Add New Category fields

(Categories panel – 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 site.
  2. Slug – The “slug” are the words that display in the URL of all posts published under a specific category. The slug can be different than 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 category hierarchies on your site (explained further below).
  4. Description – Write a brief category description 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.

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

Deleting Categories


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

You can delete categories individually, or in bulk.

Deleting A Single Category

To remove a single category, hover over the category and a menu will display containing a range of options. Click Delete to remove the category from your list …

A warning message will pop up asking you to confirm the deletion. Click OK to go ahead, or Cancel to stop …

Click 'OK' to proceed

(Click ‘OK’ to delete the category)

Deleting Multiple WordPress Categories

Let’s say that you import product data into your WordPress site containing a large number of categories (e.g. product manufacturers), and you want to reduce the number of existing 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 will be affected by deleting unnecessary categories have been reassigned to an existing or new category. For more details on reassigning categories in posts, see this tutorial: Editing And Deleting A Post In WordPress

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

Next, go through the table and unselect categories that you DO NOT want to delete. You can select/deselect categories by toggling on the check box next to the item.

Edit link

(WordPress category – Edit link)

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

Changing the category slug affects the URL of all posts assigned for 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 posts and pages have been indexed in the search engines.

WordPress Categories – Useful Tip

In WordPress, all posts must be assigned to a category. If you do not assign a post to a category, WordPress will assign your post to “Uncategorized” …

WordPress post category - 'Uncategorized'

(WordPress post category – ‘Uncategorized’)


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 meaningful to your visitors and optimize it better for search engines too.

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

Quick Edit Link

(Category table: Uncategorized – Quick Edit link)

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