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 Configure Categories In WordPressWordPress categories can help to make finding information about similar topics on your site easier for visitors. Publishing 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 add, edit & delete categories in WordPress.

Using WordPress Post Categories

Step 1: Configuring Permalinks

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

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

The same post URL can look like this:

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

To learn more about setting up permalinks, refer to this step-by-step tutorial: Changing Your WordPress Permalinks

Step 2: List Your Main Topics

Maintaining your content organized 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 to significantly boost your site’s optimization for better search engine results.

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

Useful Info

We have created a detailed tutorial on website planning here: How To Plan Your Small Business Website - A Practical Guide For Business Owners

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

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 Locations
  • Marriage Vows
  • etc.

Step 3: Select Relevant Category Topics

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Health”, etc…) is extremely difficult, especially when you’re just getting started. It’s better to focus on trying to establish your authority in a smaller 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 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 publish your posts under, it’s a good idea to consider factors like “market competition.”

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

Google Keyword Planner - Keyword research for category planning

(Keyword research - a useful tool for category planning)

When planning your topic categories, it’s important to spend time thinking carefully about all the elements you have control over (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 an unrealistic goal (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 business online.

If you need help with strategic online business areas like effective keyword research, identifying target audience demographics, etc., see this tutorial: A Practical Guide To Website Planning For 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 into categories and add them to your WordPress site.

Step 4: Set Up Your WordPress Post Categories

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

Organize posts with categories

(Organize content using categories)

To access your WordPress Post Categories area, in your Dashboard menu section, select Posts > Categories

Posts Menu - Categories

(Posts Menu – Categories)

This opens the ‘Categories’ panel …

Categories Area

(Categories Area)

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

How To Add Categories

Categories panel - Add New Category section

(WP Post Categories screen – Add New Category area)

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

WordPress Post Categories panel - Add New Category area fields

(Categories screen – Add New Category section 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” refers to the words that display in the URL of all posts published under a category. The slug can be different than 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 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.
  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. Your category description will be used for the category pages “meta” description.

Removing Categories

Important Info

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 WordPress default category (this is covered further below).

You can delete WordPress categories individually, or in bulk.

Deleting Single Categories

To delete categories individually, hover over the category you want to delete and a menu will display containing a range of options. Click the ‘Delete’ link to delete the category from your list …

How to delete single categories

(WordPress category table – Delete link)

A window will pop up asking you to confirm the deletion. Click OK to proceed, or Cancel to stop …

Click 'OK' to proceed

(Click ‘OK’ to proceed)

How To Delete Multiple Categories

Let’s say that you import product data into your site containing many different categories (e.g. product manufacturers), and you would like to reduce the number of existing categories by assigning your imported posts to a fewer number of categories. If you have 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 by deleting categories have been reassigned to an existing or new category. For more details on reassigning categories in posts, refer to this tutorial: Editing And Deleting Posts In WordPress

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

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

Select/Deselect Categories

(Selecting/Deselecting Categories)

Once you have selected all of the items you would like to delete, choose the ‘Delete’ option from the ‘Bulk Actions’ drop-down menu …

Choose 'Delete' from the 'Bulk Actions' dropdown menu

(Select the ‘Delete’ option from the ‘Bulk Actions’ dropdown menu)

With the ‘Delete’ option selected in the drop menu, click the ‘Apply’ button …

Editing Categories

To edit a post category, do the following:

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



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

'Edit Category' screen

(‘Edit Category’ section)

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

Quick Edit link - Category

(Quick Edit link)

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

Category menu - Quick Edit fields

(Quick Edit fields)


Modifying the category slug will change the URL of all posts published under 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 site is established.

WordPress Categories – Special Tip

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

'Uncategorized' category

(Post category – ‘Uncategorized’)


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 relevant to your visitors and better for search engines too.

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

Quick Edit

(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 a little extra SEO boost …

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

Now, when new posts are published under the default WordPress category, the URL will make more sense to visitors and be more effective for SEO …

Step 5 – Using WordPress Categories Effectively

Optimizing content, categories, and search engine-friendly URLs can help increase your site’s navigation and relevance in search engines, which helps drive more visitors to your site.

Here are some additional tips for getting the most benefit when using post categories.

Choose Relevant Keywords For Your Post Titles

As you create new content for your site, include the main keyword of your post in the title of your post, preferably near the beginning. This helps to optimize your page for search engines, and improves clickthrough rates.

So, for example, if writing a blog post on Outdoors Adventure Travel focused on the ”Kayaking” niche could be titled “Kayaking In Australia – 10 Unforgettable Kayaking Adventures“.

Publish Your WordPress Posts Under Relevant Categories

Every time you add a new article or post, remember to select a relevant category box before publishing the post …
