Using Categories In WP PostsWordPress categories help to make finding information about similar topics on your site easier for visitors. Filing posts under categories also helps to keep you content organized and allows search engines to better index your WordPress site.

This tutorial helps you learn how to set up categories in posts.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Out of the box, WordPress URLs are not really 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 let you display search engine friendly URLs, so instead of having a web address that looks like this:

The post URL can display like this:

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

For more information about configuring and using permalinks, go here: Changing WordPress Permalinks

Step 2: Create A List Of Topics

Maintaining your content organized is very 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.

The first step, therefore, is to plan what kind of broad “topics” you will be writing about. These can be topics related to your specific niche, your business, and even your industry.


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

When creating a list of topics, include areas of your business that you believe 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 valuable content like ongoing training, tips, etc.) and/or refer to others.

Let’s say, for example, that you would like 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 Tips
  • Marriage Vows
  • and so on …

Step 3: Select Relevant Category Topics

Dominating an entire market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is extremely hard, especially when you’re just getting started. It’s better to focus on building your authority in a niche, or a 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 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 choosing 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 the sample keywords …

Google Keyword Planner - Keyword research tool for category planning

(Use keyword research to help with 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 gain a competitive advantage. If you set an unrealistic 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 sub-niche, you could experience little to no activity on your site and hence no significant opportunities to increase your market share online.

For tutorials on online business planning like effective keyword research, identifying audience demographics, etc., see this tutorial: A Money-Saving Guide To Website Planning For Non-Technical 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 into WordPress post categories.

Step 4: Set Up Categories

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

WordPress allows you to easily organize content by categories

(Organize posts with categories)

To access your Categories area, log into the WP Dashboard and choose Posts > Categories

Posts - Categories

(Posts – Categories)

This brings you to the ‘Categories’ screen …

(Post Categories Section)

Here you can add, edit, and remove categories, including adding category descriptions and other information that can optimize your site for search engines.

How To Add Categories To WordPress

(Post Categories screen – Add New Category section)

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

WordPress Post Categories screen - Add New Category area fields

(Categories screen – Add New Category fields)

  1. Name – Enter 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” refers to the words that display in the URL of all posts published under a specific category. The slug can be different from 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 automatically create one for you using a lower case version of your 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 your category pages “meta” description.

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

How To Delete WordPress Post Categories

Important Info

Deleting a category does not delete posts assigned to that category. Instead, posts that were 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.

How To Delete Categories Individually

To delete a single category, hover over the category and click the ‘Delete’ link …

Delete link


A message will appear in your browser asking you to confirm the deletion. Click OK to go ahead, or Cancel to stop …

Click 'OK' to delete the category

(Click ‘OK’ to delete the category)

How To Delete WordPress 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 there are too many categories to delete individually, this is where the bulk delete feature can be useful.


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 reassigning post categories, visit this tutorial: Editing And Deleting A Post In WordPress

To bulk delete WordPress categories, click the main checkbox in the header row. This will select all category entries on the page.

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

Select/Deselect Categories

(Select/Deselect Categories)

Once you have selected all of the items to be deleted, choose the ‘Delete’ option from the ‘Bulk Actions’ dropdown menu …

Editing WordPress Post Categories

To edit a category, do this:

Go to your ‘Categories’ table, find the item that needs to be edited, then place your mouse over the category name, and click Edit

Edit - Category table menu


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

'Edit Category' screen

(‘Edit Category’ screen)

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

WordPress post category table - Quick Edit

(Quick Edit)

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

Quick Edit screen

(Quick Edit screen)


Changing the category slug will change the URL of posts published under that category. This can lead to “page not found” errors when visitors click on links pointing to posts that have already been indexed by search engines.

For this reason, it’s best to invest 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 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 attribute your post automatically to the default category “Uncategorized” …

'Uncategorized' WordPress post category

(’Uncategorized’ category)

Useful Information

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 users and optimize it better for search engines too.

Place your mouse over the “Uncategorized” entry and click on the ‘Quick Edit’ link …

Quick Edit

(Category table menu: Uncategorized – 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” in order to give your site an extra SEO boost …
