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 & Delete Categories In WordPressWordPress post categories help to make finding information on your site easier for visitors. Publishing posts under categories also helps to organize your content and allows search engines to better index your WordPress site.

Learn how to set up & use post categories in WordPress in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

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

You can have the same post URL look like this:

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

To learn more about permalinks, refer to this tutorial: Configuring WordPress Permalinks

Step 2: List Your Topics

Maintaining your site’s 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 search engine results.

The first step, then, is to carefully plan 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.

When creating your 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 repeatedly to 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 the following:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Locations
  • Commitment Ceremonies
  • and so on …

Step 3: Choose Relevant Category Names

Dominating an entire market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is extremely difficult, especially if you’re just starting out. you have a better chance of getting somewhere by focusing on building your authority in a smaller niche, or a segment (i.e. subniche) 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 sub niche (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 consider 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 sample keywords …

Google Keyword Planner - Keyword research for category planning

(Use keyword research to help plan your categories)

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 to use these elements to gain a competitive advantage. If you set too big a goal (i.e. trying 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 sub-niche, you could experience little to no activity on your site and hence no significant opportunities to increase your market share online.

If you need help with strategic online business online strategies like keyword research, identifying audience demographics, etc., refer to this tutorial: A Cost-Saving 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 turn these keywords into categories and add them to your WordPress site.

Step 4: Set Up Categories

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

How To Add Post Categories To WordPress

(Post Categories panel – Add New Category)

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

WordPress Post Categories panel - Add New Category fields

(Post Categories screen – Add New Category section fields)

  1. Name – Enter 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 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 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 using a lower case version of your 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 search engine optimization. WordPress uses the category description you write here for the category pages “meta” description.

Deleting Categories In WordPress

Useful Info

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

You can delete categories individually, or in bulk.

Deleting Categories Individually

To delete a specific category, hover over the category you would like to delete and click Delete

WordPress post category - Delete

(Delete link)

A warning message will pop up asking you to confirm the deletion. Click OK to permanently delete the item, or Cancel to abort …

Click 'OK' to proceed

(Click ‘OK’ to proceed)

Deleting Multiple Categories

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 existing categories by assigning your imported posts to a fewer number of categories. If you have 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 unnecessary categories are deleted have been reassigned to an existing or new category. For more details on reassigning post categories, go to this tutorial: Editing And Deleting A WordPress Post

To bulk delete categories, click the main checkbox next to the ‘Name’ column title. This will select all category items on the page.

Next, go through the table and untick the box next to categories that you DO NOT want to delete. You can select/deselect categories by toggling on the check box next to the item.

Select/Deselect Categories

(Select/Deselect Categories)

Once you have ticked all the items you would like to delete, choose the ‘Delete’ option from the ‘Bulk Actions’ dropdown menu …

To edit a post category in WordPress, do this:

In your ‘Categories’ section, find the category entry that you would like to edit, then place your mouse over the category title, and click Edit

Edit - Category table menu

(WordPress category menu – Edit)

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

(Quick Edit)

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

(Category table – Quick Edit screen)


Important: Modifying the category slug will change 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 Post Categories – Useful Tip

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

Post category - 'Uncategorized'

(’Uncategorized’ category)


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 relevant to your readers and optimized for search engines too.

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

Quick Edit

(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” in order to give your site a little extra SEO boost …

Change 'Uncategorized' category to something more meaningful to your site visitors and search engines

(Change ‘Uncategorized’ category to something more meaningful to your site visitors and search engines)
