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.

Adding, Editing & Deleting Categories In PostsWordPress categories help to 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.

Learn how to configure categories in this step-by-step tutorial.

Step 1: Configuring Permalinks

Default WordPress post URLs aren’t very 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 let you display search engine friendly URLs, so instead of having a post link that looks like this:

The post URL can display like this:

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

To learn more about configuring permalinks, see this step-by-step tutorial: Setting Up Your WordPress Permalinks

Step 2: Create A List Of Your Main Topics

Keeping 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 to boost your site’s optimization for better search engine results.

We recommend, therefore, planning what kind of broad “topics” you will write about and publish on your website or blog. These can be topics related to your niche, your services or products, and even your industry.

Important Info

If you need help website planning, go here: A Cost-Saving Guide To Website Planning For Non-Technical Business Owners

When creating a list of topics, remember to 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 online authority that 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 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 Locations
  • Commitment Ceremonies
  • etc.

Step 3: Select Relevant Category Topics

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Health”, etc…) is extremely difficult, especially if you’re just getting started. you have a better chance of getting somewhere by focusing on building your authority in a niche, or a sub niche 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 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 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 …

Use keyword research tools to help with category planning

(Keyword research - a useful 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 have control over (like the keywords that will be used throughout your content), and how you are going to use these elements to gain 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 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 online strategies like keyword research, identifying target audience demographics, etc., visit this tutorial: Planning Your Small Business Website - A Basic Blueprint For Business Owners

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

Step 4: Set Up Your Categories

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

Organize your content with categories

(WordPress lets you easily organize content by categories)

To access your Post Categories area, in your Dashboard, click on Posts > Categories

WP Posts Menu - Categories

(Posts Menu – Categories)

This opens the ‘Categories’ panel …

Categories Panel

(WordPress Post Categories Panel)

This area allows you to create, edit, and remove categories, including inserting descriptions for categories and other information that can optimize your website for search engines.

Adding Post Categories To WordPress

Post Categories panel - Add New Category section

(Post Categories screen – Add New Category area)

To create a new category in WordPress, simply fill in the fields in the ‘Add New Category’ area as per the example below:

Post Categories panel - Add New Category section fields

(Categories panel – Add New Category fields)

  1. Name – Enter 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 display in all the category-related sections of your site.
  2. Slug – The “slug” refers to 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 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.

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

How To Delete Categories

Useful 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 categories individually, or in bulk.

Deleting Categories Individually

To delete an individual category, hover over the category and click the ‘Delete’ link …

WordPress category - Delete link

(Deleting single categories)

A warning message will appear in your browser 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 Multiple WordPress Categories

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 consolidate posts to a single category. 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 will be affected when unnecessary categories are removed have been reassigned to an existing or new category. For more details on how to reassign categories in posts, see this tutorial: How To Edit And Delete WordPress Posts

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

Next, go through the list 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.

Select/Deselect Categories

(Selecting/Deselecting Categories)

After selecting all of the categories you would like to delete, choose the ‘Delete’ option from the ‘Bulk Actions’ drop menu …

Select 'Delete' from the 'Bulk Actions' drop-down menu

(Select the ‘Delete’ option from the ‘Bulk Actions’ drop-down menu)

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

(Bulk deleting categories)

The selected categories will be removed …

Editing Post Categories

To edit a WordPress post category, do this:

In your ‘Categories’ section, locate the item that you would like to edit, then hover over the category title, and click Edit

WordPress post category table - Edit

(Edit – Category table menu)

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

'Edit Category' screen

(‘Edit Category’ panel)

You can also edit information in a category using the Quick Edit option. Hover over the category title you would like to edit and click the ‘Quick Edit’ link …

Quick Edit link - WordPress category table

(Quick Edit – WordPress post category)

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

Category - Quick Edit screen

(Quick Edit fields)


Modifying the category slug changes the URL of posts assigned to 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, we recommend investing 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 already been indexed in the search engines.

WordPress Post 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 assign your post to a default category called “Uncategorized” …

Category - 'Uncategorized'

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

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

Category: Uncategorized - Quick Edit

(Quick Edit)

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” to give your site an extra SEO boost …

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

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

Step 5 – Using WordPress Categories Effectively

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

To improve your results further, here are some tips for getting the most benefit from using categories.

Choose Relevant Keywords For Your Post Titles

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

So, for example, a blog post for an Outdoors Adventure Travel company targeting the “Winter Camping” niche could be titled “Winter Camping Tips – 10 Essential Survival Tools You Will Need For Your Winter Camping Trip“.

Publish Posts Under The Most Relevant Post Category

Every time you add a new article or post to your website or blog, remember to tick a category box before publishing your post …
