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 Set Up And Use Categories In PostsWordPress post categories help make finding information on your site easier for visitors. Filing posts under categories also helps to organize your content and allows search engines to better index your WordPress site.

In this tutorial, you will learn how to add, edit & delete WordPress categories.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Default WordPress post URLs are not 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 allow your WordPress site to display search engine friendly URLs, so instead of having a web address that looks like this:

You can have the same post URL look like this:

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

We have written a detailed tutorial about permalinks here: Using Permalinks To Improve Your WordPress SEO

Step 2: Create A List Of Your Main Topics

Keeping your 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 to boost your site’s optimization for improved SEO.

We recommend, therefore, first planning what kind of broad “topics” you will publish on your site. These can be topics related to your specific niche, your business, your industry, etc.


We have created a detailed tutorial on website planning here: How To Plan Your Business Website - A Money-Saving Blueprint For Non-Technical Business Owners

When creating a 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 important in terms of establishing your web site as an online authority that visitors will want to come back again to learn from 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:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Locations
  • Marriage Vows
  • etc.

Step 3: Choose Relevant Category Headings

Dominating an entire market (i.e. “Weddings”, “Travel”, “Health”, etc…) is very difficult, especially if you’re just starting out. It’s better to try and establish your authority in a smaller niche, or micro niche of your main market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see from the above Market > Niche > Subniche 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 publish your posts under, it’s a good idea to take into account 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 – Useful keyword research tool for category planning)

When planning your main 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 site), and how 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 microniche, you could experience little to no activity on your site and hence no significant opportunities to increase your market share online.

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

Step 4: Set Up Your Categories

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

Organize content with categories

(WordPress lets you easily organize your posts with categories)

To access your Post Categories section, log into the WordPress Dashboard and choose Posts > Categories

Posts - Categories

(Posts Menu – Categories)

This brings you to the ‘Categories’ panel …

Categories Panel

(Post Categories Panel)

Here you can add, edit, and delete categories, including inserting category descriptions and other information that can help to improve your site’s SEO.

How To Add WordPress Categories

Categories screen - Add New Category

(Categories panel – Add New Category)

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

WordPress Post Categories screen - Add New Category fields

(Categories screen – Add New Category fields)

  1. Name – Use 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 the category-related sections of your website.
  2. Slug – The “slug” are the words that display in the URL of all posts published under a 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 hierarchies of categories 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 SEO. Your category description will be used for the category pages “meta” description.

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

Removing Categories


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

You can delete categories individually, or in bulk.

How To Delete Categories Individually

To remove a specific category, place your mouse over the category and a menu will display containing various options. Click Delete to delete the category from your list …

How to delete an individual category

(Category table menu – Delete)

A 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 proceed)

How To Delete Multiple WordPress Categories

Let’s say that you import product data into your site containing many different categories (e.g. an e-commerce catalog), and you would like to consolidate posts to a single category. If there are too many categories to delete one at a time, this is where the bulk delete feature can be useful.


Important: Make sure that any posts that will be affected by deleting categories have been reassigned to an existing or new category. For more details on how to reassign post categories, refer to this tutorial: Editing And Deleting A Post

To delete multiple categories, click the main checkbox 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. Select/deselect categories by toggling on the check box next to the item.

Editing Categories In WordPress

To edit a WordPress post category, do the following:

Go to your ‘Categories’ screen, find the item that you would like to edit, then hover over the category name, and click Edit


(Category table menu – Edit)

This brings up the ‘Edit Category’ panel. Edit the category fields, and click Update to save your new details …

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 – Category table)

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

(Category table – Quick Edit screen)


Modifying the category slug affects the URL of 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, 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 Category – Special Tip

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

WordPress post category - 'Uncategorized'

(Category – ‘Uncategorized’)


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 meaningful to your readers and better for search engines too.

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

Category Table Menu: Uncategorized - Quick Edit

(Category table menu: Uncategorized – Quick Edit)

Change 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 …

Step 5 – Using Categories Effectively

Optimizing content, categories, and search-friendly URLs helps to improve 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 from using post categories.

Choosing Keyword-Relevant Post Titles

In your content strategy, try to include the main keyword of your post in the title of your post, 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 business targeting the “Winter Camping” niche could be titled “Winter Camping Tips – 5 Survival Accessories You Will Need For Your Winter Camping Trip“.

Publish Posts Under The Correct Post Category

Each time you add a new article or post to your website or blog, remember to select the most relevant category box before publishing the post …
