Add, Edit & Delete WordPress Post CategoriesWordPress post categories can help to make finding information about similar topics on your site easier for visitors. Categories also help to organize your content and allow search engines to better index your WordPress site.

This tutorial helps you learn how to set up & use categories in WordPress.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post URLs aren’t search engine friendly. In order to make the best use of 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 post URL look like this:

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

If you need help with permalinks, see this step-by-step tutorial: Improve Your WordPress SEO Using SEO-Friendly URLs

Step 2: List Your Main Topics

Keeping 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 searching for, but can also help search engines to better index your content.

We recommend, therefore, first planning 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.


To learn more about website planning, see this tutorial: A Basic Guide To Website Planning For Business Owners

When creating your list of topics, include areas of your business that your visitors, prospects, and clients should 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 come back again to learn from and/or refer to others.

Let’s say, for example, 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:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Tips
  • Commitment Ceremonies
  • etc.

Step 3: Choose Relevant Category Headings

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is very hard to do, especially when you’re just starting out. It’s better to try and establish your authority in a niche, or a subniche of your market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see in the above 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 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 online searches performed each month for each of the sample keywords …

Google Keyword Planner - Useful keyword research for category planning

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

When planning your topic categories, it’s important to spend time thinking carefully about all the elements you can control (like the keywords that will be used throughout your site), and how you are going to use these elements to try to a competitive advantage. If you set an unrealistic goal (i.e. trying to dominate the entire online “Wedding” market), you will only end up feeling disappointed. If, on the other hand, you focus on a very narrow niche or sub-niche, you could experience little to no activity on your site and hence no significant opportunities to grow your business online.

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 Your Post Categories

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

WordPress allows you to easily organize your content with categories

(Organize content with categories)

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

Posts - Categories

(Posts – Categories)

This opens the ‘Categories’ panel …

Categories Screen

(Categories Area)

This section allows you to create, edit, and delete categories, including adding category descriptions and other information that can help to optimize your website or blog for search engines.

(Categories panel – Add New Category area)

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

WP Post Categories panel - Add New Category fields

(Post Categories panel – Add New Category section fields)

  1. Name – Enter 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 then display in all the 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 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 – Add a brief description of your category here. Some WordPress themes display this category description, and it can help with SEO. WordPress uses the category description you write here for the category pages “meta” description.

Deleting Post Categories In WordPress

Important Info

Deleting a category does not delete the posts assigned to that category. Instead, any posts assigned to the deleted category 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 a single category, place your mouse over the category and a menu will display containing a range of options. Click the ‘Delete’ link to delete the category from your list …

How to delete an individual category

(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 proceed

(Click ‘OK’ to proceed)

How To Delete 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 reduce the number of 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.

Useful Information

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 Post

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

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

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

Editing Categories

To edit a category in WordPress, do the following:

Go to your ‘Categories’ screen, find the category that you would like to edit, then place your mouse over the category title, and click Edit


(Edit link)

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

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

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 Categories – Useful Tip

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

Post category - 'Uncategorized'

(Post category – ‘Uncategorized’)

Useful Info

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

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

Quick Edit

(Quick Edit link)

Change the Category Name and Category Slug to a keyword or keyword phrase that will be 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” to give your site a little extra SEO boost …

Step 5 – Use WordPress Post Categories Effectively

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

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

Choosing Relevant Keywords For Your Post Titles

SEO experts recommend including the main keyword of your post in your your post title, preferably near the beginning. This helps to optimize your page for search engines, and improves click through rates.

So, for example, a blog post on Outdoors Adventure Travel focused on the “Winter Camping” niche could be titled “Winter Camping Tips – 5 Survival Tools Everyone Needs For A Safe Winter Camping Trip“.

Publish Your WordPress Posts Under Relevant Categories
