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 Add, Edit, And Delete WordPress CategoriesWordPress categories can help to make finding information 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.

Learn about adding, editing & deleting categories in WordPress in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

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

Permalinks let you display SEO-friendly URLs, so instead of having a post link that looks like this:

The same post URL can display like this:

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

To learn more about setting up and using permalinks, see this tutorial: How To Improve Your WordPress SEO With Permalinks

Step 2: Make A List Of Your Main Topics

Maintaining content organized 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 significantly boost your site’s optimization for better SEO.

We recommend, therefore, planning what kind of broad “topics” you will be writing about. These can be topics related to your niche, your products or services, your industry, etc.

Important Info

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

When creating your list of topics, 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 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 other people to.

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
  • and so on …

Step 3: Choose Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Business”, 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 subset of your 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 “Weddings” market (another category).

When choosing the keywords you would use as a top-level category to file 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 above keywords …

Keyword research - a useful tool for category planning

(Keyword research can help you with 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 site), and how to use these elements to gain a competitive advantage. If you set too big a goal (i.e. aiming to dominate the online “Wedding” market), you will only end up feeling disappointed. If, on the other hand, you focus on a very narrow niche or microniche, you could experience little to no activity on your site and hence no significant opportunities to increase your business online.

For tutorials on strategic online business planning like keyword research, identifying target audience demographics, etc., visit this tutorial: The Website Planning Process Explained - A Basic Blueprint 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 categories and add them to your WordPress site.

Step 4: Set Up Your Categories

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

WordPress lets you easily organize your content using categories

(Organize content using categories)

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

To create a new post category in WordPress, complete the fields in the ‘Add New Category’ area as shown below:

WP Post Categories screen - Add New Category area fields

(WP Post Categories panel – Add New Category area 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 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 category description here. Some WordPress themes display this category description, and it can help with search engine optimization. WordPress uses the category description you write here for the category pages “meta” description.

To learn how to create or edit WordPress posts, see the tutorials below:

Deleting Categories In WordPress


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

You can delete WordPress categories individually, or in bulk.

How To Delete Categories Individually

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

Delete - Category table

(Deleting single categories)

A message will appear asking you to confirm the deletion. Click OK to permanently delete the item, or Cancel to stop …

Click 'OK' to proceed

(Click ‘OK’ to proceed)

Deleting 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 want to consolidate posts to a fewer number of categories. If you have too many categories to delete individually, this is where the bulk delete feature can be useful.


Important: Make sure that any posts that may be affected when unwanted categories are deleted have been reassigned to an existing or new category. For more details on reassigning categories in posts, refer to this tutorial: Editing And Deleting Posts In WordPress

To delete multiple categories, click the main check box next to the ‘Name’ column title. This will select all category listings on the page.

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

Important Info

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

Post Category – Useful 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 automatically to “Uncategorized” …

'Uncategorized' category

(WordPress post 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 posts as “uncategorized”, let’s make the category a little more meaningful to your site readers and better for search engines too.

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

Category: Uncategorized - Quick Edit Link

(Category menu: Uncategorized – Quick Edit)

Change 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” in order to give your site an extra SEO boost …

Optimizing content, categories, and search engine and visitor friendly URLs can help improve your site’s navigation and relevance in the search engines, which helps drive more visitors to your site.

Here are some more tips for getting the most benefit from using categories.
