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 PostsWordPress post categories help make finding information on your site easier for visitors. Categories also help search engines to better index your WordPress site.

Learn how to configure and use WordPress categories in this tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post URLs are not 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 WordPress to display SEO-friendly URLs, so instead of having a web address that looks like this:

You can have the same post URL display like this:

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

For a detailed tutorial on using permalinks, go here: How To Improve Your WordPress SEO Using Permalinks

Step 2: Make A List Of Your Main Topics

Keeping 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 improved search engine results.

The first step, then, is to plan 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.


We have created a detailed tutorial on website planning here: The Web Site Planning Process Explained: A Money-Saving Guide For Non-Technical Business Owners

When creating your list of topics, remember to 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 web site as an “authority” that online 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 would like to start a site 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 Tips
  • Commitment Ceremonies
  • and so on …

Step 3: Select Relevant Category Headings

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is extremely hard, especially if you’re just getting started. It’s better to focus on building your authority in a smaller niche, or a subniche 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 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 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 these keywords …

Keyword research - a useful tool for category planning

(Use keyword research to help plan your categories)

When planning your topic categories, it’s important to take your time and think carefully about all the elements you have control over (like the main keywords used throughout your content), and how to use these elements to try and gain a competitive advantage. If you set too big a goal (i.e. dominating the entire 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 market share online.

For tutorials on strategic online business online strategies like keyword research, identifying target audience demographics, etc., refer to this tutorial: A Comprehensive Guide To Web Site Planning For Business Owners

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

Step 4: Set Up WP Post Categories

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

Organize your content by categories

(WordPress lets you easily organize posts with categories)

To access your WordPress Categories section, log into your WordPress site, then go to your navigation menu and select Posts > Categories

WP Posts Menu - Categories

(WordPress Posts Menu – Categories)

This brings you to the ‘Categories’ panel …

Post Categories Screen

(Categories Area)

This section lets you create, edit, and delete categories, including inserting descriptions for categories and other information that can improve your website’s SEO.

How To Add Post Categories

Categories screen - Add New Category

(Categories screen – Add New Category)

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

Categories panel - Add New Category fields

(Post Categories screen – Add New Category area 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 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. The slug can be different than 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 (explained further below).
  4. Description – Write a brief category description here. Some WordPress themes display this category description, and it can help with SEO. Your category description will be used for your category pages “meta” description.

How To Delete Categories

Important Info

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

You can delete WordPress categories individually, or in bulk.

Deleting Single Categories

To delete single categories, hover over the category you would like removed and click the ‘Delete’ link …

Delete link

(Delete link)

A warning 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 delete the category)

Deleting Multiple Categories

Let’s say that you import product data into your site containing many different categories (e.g. product manufacturers), and you want to consolidate posts to a single category. 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 will be affected when categories are removed have been reassigned to an existing or new category. For more details on reassigning post categories, see 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 items .

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

Editing Post Categories

To edit a category, do the following:

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

Edit - WordPress category menu

(Edit link – WordPress post category)

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

(Quick Edit link)

(Quick Edit fields)


Changing the category slug will change the URL of posts assigned for that category. This can lead to “page not found” errors when visitors click on links pointing to posts published elsewhere.

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

'Uncategorized' category

(WordPress post category – ‘Uncategorized’)

Important Info

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 meaningful to your site users and optimized for search engines too.

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

Quick Edit Link

(Category table: Uncategorized – Quick Edit)

Change both 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” to give your site a little extra SEO boost …

Note: The site used in the example above has been configured to display search engine-friendly URLs, with the Permalinks set to display posts as “domain/category/post title”. For more details on how to set up SEO-friendly URLs, go here: Improve Your WordPress SEO With SEO-Friendly URLs
