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 Post CategoriesWordPress post categories can help to 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 search experience and your search engine rankings.

This step-by-step tutorial helps you learn about configuring & using categories in WordPress posts.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post URLs are not very search engine friendly. In order to make the best use of 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 web address that looks like this:

The post URL can look like this:

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

We have created a detailed tutorial about permalinks here: How To Improve Your WordPress SEO With Permalinks

Step 2: Create A List Of Your Main Topics

Keeping your site’s 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 search engines to better index your content.

The first step, then, is to carefully work out what kind of broad “topics” you will write about. These can be topics related to your specific niche, your services or products, your industry, etc.


If you need help with planning a website, refer to this step-by-step tutorial: A Basic Guide To Web Site Planning For Business Owners

When creating a list of topics, remember to 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 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 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 the following:

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

Step 3: Select Relevant Category Headings

Dominating an entire market (i.e. “Weddings”, “Travel”, “Health”, etc…) is very hard to do, especially when you’re just starting out. It’s better to focus on building your authority in a smaller 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 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 take into account 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 …

Keyword research - a useful tool for category planning

(Google Keyword Planner – Useful keyword research for category planning)

When planning your category names, 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 you are going to use these elements to gain a competitive advantage. If you set too big a goal (i.e. dominating the 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 market share online.

For tutorials on strategic online business areas like effective keyword research, identifying target audience demographics, etc., refer to this tutorial: A Comprehensive 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 turn these keywords into post categories.

Step 4: Set Up Categories

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

(WordPress lets you easily organize content using categories)

To access your WordPress Post Categories area, go to the administration area and choose Posts > Categories

Posts - Categories

(Posts – Categories)

This brings you to the ‘Categories’ screen …

Post Categories Section

(Categories Area)

This section lets you add, edit, and delete categories, including inserting descriptions for categories and other information that can help to optimize your site for search engines.

How To Add Post Categories

Categories panel - Add New Category area

(Categories screen – Add New Category area)

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

Categories panel - Add New Category area fields

(Categories panel – Add New Category section fields)

  1. Name – Type 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 site.
  2. Slug – The “slug” are the words that display in the URL of all posts published under a specific category. Your 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 your category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website.
  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.

Click Add New Category when done to add your new category …

How To Remove WordPress Categories

Useful Info

Deleting a category does not delete 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 Categories Individually

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

How to delete categories individually

(How to delete single categories)

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

Click 'OK' to delete the category

(Click ‘OK’ to proceed)

Deleting WordPress Categories In Bulk

Let’s say that you import product data into your site containing many different categories (e.g. product manufacturers), and you want to consolidate posts to a single category. If there are 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 when categories are removed have been reassigned to an existing or new category. For more details on reassigning categories in posts, refer to this tutorial: How To Edit And Delete Posts

To bulk delete categories, click the main check box in the header row. This will select all category items .

Next, go through the list and unselect 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 ticked all the categories you want to delete, select the ‘Delete’ option from the ‘Bulk Actions’ pulldown menu …

Editing Post Categories

To edit a WordPress post category, do the following:

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

Edit link

(WordPress post category menu – Edit link)

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

'Edit Category' screen

(‘Edit Category’ section)

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

Quick Edit link

(Quick Edit – Category table menu)

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

Quick Edit fields

(Category – Quick Edit screen)


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

For this reason, we strongly 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 assign your post to “Uncategorized” …

'Uncategorized' category

(WordPress post category – ‘Uncategorized’)

Important 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 meaningful to your visitors and better for search engines too.

Hover over the “Uncategorized” entry and click on Quick Edit

Category Table Menu: Uncategorized - Quick Edit Link

(Quick Edit)

Change both 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 …

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

Choose Relevant Keywords For Your Post Titles

As you create new content for your site, try to include the main keyword of your post in the title of your post, preferably at the beginning. This helps to optimize your page for search engines, catch your visitor’s attention.

So, for example, an article for an Outdoors Adventure Travel site targeting the “Winter Camping” niche could be titled “Winter Camping Tips – 10 Survival Accessories Everyone Needs For A Safe Winter Camping Adventure“.
