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 And Using CategoriesWordPress categories help to make finding information about similar topics on your site easier for visitors. Adding post categories not only helps to organize your content, it also improves both your visitor’s experience and your search engine rankings.

In this tutorial, you will learn how to configure WordPress categories.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Out of the box, WordPress post URLs aren’t 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 SEO-friendly URLs, so instead of having a post link that looks like this:

The post URL can look like this:

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

We have created a detailed tutorial on permalinks here: How To Improve Your WordPress SEO With SEO-Friendly URLs

Step 2: Create A List Of Your Main Topics

Maintaining your content organized at all times 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 search engines to better index your content.

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

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 very important in terms of establishing your site as an “authority” that online visitors will want to come back repeatedly to and/or refer other people to.

Let’s say, for example, 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
  • Commitment Ceremonies
  • and so on …

Step 3: Choose Relevant Category Headings

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is very hard to do, especially when you’re just starting out. It’s better to try and establish your authority in a smaller niche, or a micro niche 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 subniche (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 publish your posts under, it’s a good idea to take into account factors like “market competition.”

For example, the screenshot below shows Google’s estimates for the average number of online searches performed each month for each of the above keywords …

Keyword research can help you with category planning

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

When planning your main topic categories, it’s important to take your time and think carefully about all the elements you can control (like the keywords that will be used throughout your content), and how you are going to use these elements to try and 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 narrow niche or microniche, you could experience little to no activity on your site and hence no significant opportunities to grow your business online.

For tutorials on online business planning like effective keyword research, identifying target audience demographics, etc., see this tutorial: A Basic 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 these into WordPress post categories.

Step 4: Set Up Your Categories

Publishing posts under categories that best relate to the main topics of your site helps 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 your content by categories

(WordPress lets you easily organize your posts by categories)

To access your WordPress Categories section, in your main menu section of your WordPress admin, click on Posts > Categories

In this screen, you can add, edit, and remove categories, including adding category descriptions and other information that can help to optimize your website for search engines.

How To Add Categories To WordPress

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

Categories panel - Add New Category section fields

(WordPress Post Categories screen – 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 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 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 your category pages “meta” description.

Removing Categories


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

How To Delete Categories Individually

To delete single categories, hover over the category you would like to delete and a menu will display containing various options. Click Delete to delete the category from your list …


(Delete link – WordPress category)

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

Click 'OK' to proceed

(Click ‘OK’ to delete the category)

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 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 will be affected when unnecessary categories are removed have been reassigned to an existing or new category. For more details on how to reassign post categories, see this tutorial: How To Edit And Delete WordPress Posts

To bulk delete categories, click on 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. You can select/deselect categories by toggling on the checkbox next to the item.

Select/Deselect Categories

(Selecting/Deselecting Categories)

Once you have ticked all of the items you would like to delete, select the ‘Delete’ option from the ‘Bulk Actions’ drop-down menu …

How To Edit Post Categories In WordPress

To edit a category in WordPress, do this:

In your ‘Categories’ screen, find the category item to be edited, then hover over the category name, and click the ‘Edit’ link …

Category table menu - Edit


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

'Edit Category' panel

(‘Edit Category’ screen)

You can also edit a category using the Quick Edit option. Hover over the category title you would like to edit and click on Quick Edit

Quick Edit link - Category table

(WordPress post category menu – Quick Edit)

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

Category - Quick Edit screen

(Category – Quick Edit fields)


Changing the category slug changes the URL of all posts assigned to that category. This can lead to “page not found” errors when visitors click on links to posts that have already been indexed by search engines.

For this reason, we recommend investing time into planning your categories before publishing content, and avoid changing the post category slug afterward if at all possible, especially after your site is established.

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 automatically attribute your post to the default category “Uncategorized” …

'Uncategorized' WordPress category

(WordPress post category – ‘Uncategorized’)


The default category cannot be deleted.

Attributing posts to 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 readers 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: Uncategorized – Quick Edit link)

Change both the Category Name and Category Slug to a keyword or keyword phrase that will be generally 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” to give your site a little extra SEO boost …

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

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

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

Choosing Relevant Keywords For Your Post Titles

SEO experts recommend including the main keyword of your post in the the title of your post, preferably near the beginning. This helps to optimize your post for search engines, and improves click-through rates.

So, for example, if writing a blog post on Outdoors Adventure Travel focused on the “Winter Camping” niche could be titled “Winter Camping Tips – 10 Essential Survival Tools Everyone Needs For A Safe Winter Camping Adventure“.

Publish Your Posts Under Relevant Categories
