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 …

Configuring CategoriesWordPress post categories help to make finding information about similar topics on your site easier for visitors. Adding categories to your site 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 add, edit, and delete categories in WordPress in this tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post web addresses aren’t search engine friendly. In order to make the best use of categories, you will need to modify the way WordPress displays your URLs.

Permalinks allow your WordPress site to display SEO-friendly URLs, so instead of having a web address that looks like this:

You can have the post URL display like this:

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

To learn more about setting up and using permalinks, refer to this step-by-step tutorial: Improve Your WordPress SEO With SEO-Friendly URLs

Step 2: Make 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 searching for, but can also help to significantly boost your site’s optimization for improved SEO.

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


We have created a detailed tutorial on website planning here: How To Plan Your Business Web Site: A Money-Saving Guide 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 website as an online authority that visitors will want to subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer other people to.

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:

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

Step 3: Select Relevant Category Headings

Dominating an entire market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is extremely difficult, especially when you’re just getting started. It’s better to try and build your authority in a smaller niche, or subset 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 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 selecting 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 the above keywords …

Google Keyword Planner - Useful keyword research for category planning

(Use keyword research tools to help with category planning)

When planning your 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 you are going to use these elements to try to a competitive advantage. If you set too big a goal (i.e. aiming 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 market share online.

If you need help with strategic online business areas like effective keyword research, identifying target audience demographics, etc., refer to this tutorial: A Comprehensive Guide To Web Site Planning For Non-Technical Business Owners

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

Step 4: Set Up Your Post Categories

Publishing 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 site visitors with a better user experience, and helps to optimize your web pages for search engines.

WordPress allows you to easily organize your posts with categories

(WordPress allows you to easily organize content using categories)

To access your WordPress Categories area, in the main menu of your administration area, choose Posts > Categories

Posts - Categories

(Posts – Categories)

This opens the ‘Categories’ screen …

(WordPress Post Categories Area)

Here you can add, edit, and delete categories, including adding descriptions for categories and other information that can improve your site’s SEO.

How To Add Post Categories

(WP Post Categories panel – Add New Category)

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

Categories screen - Add New Category fields

(Categories screen – Add New Category fields)

  1. Name – Type 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 then display in all category-related sections of your site.
  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 automatically 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 website (explained further below).
  4. Description – Write a brief category description 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 when done to add the new category …

How To Delete WordPress Categories

Useful Information

Removing a category does not delete the posts assigned to that category. Instead, posts assigned to the deleted category will be reassigned to the default category (this is covered further below).

You can delete WordPress categories individually, or in bulk.

How To Delete An Individual Category

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

(Delete link – WordPress post category table menu)

A window 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 delete the category)

Deleting WordPress Categories In Bulk

Let’s say that you import product data into your WordPress site containing many different 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 one at a time, this is where the bulk delete feature comes in handy.


Important: Make sure that any posts that will be affected when categories are deleted have been reassigned to an existing or new category. For more details on reassigning post categories, refer to this tutorial: How To Edit And Delete A Post

To delete multiple categories, click on the main checkbox in the header row. This will select all category items .

Useful Info

Changing the category slug will affect 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 category slug afterward if at all possible, especially after your site is established.

Post 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 the default category “Uncategorized” …

'Uncategorized' category

(’Uncategorized’ post category)


The default category cannot be deleted.

Assigning posts to 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 meaningful to your site visitors and optimized for search engines too.

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

Category Table: Uncategorized - Quick Edit Link

(Category table menu: Uncategorized – Quick Edit)

Change both the Category Name and Category Slug to a keyword or keyword phrase that will be generally 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 …
