How To Set Up Post Categories In WordPressWordPress post categories help make finding information on your site easier for visitors. Adding post categories not only helps to organize your content, it also improves both your visitor’s search experience and your search engine rankings.

Learn about configuring categories in WordPress in this tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

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

Permalinks let you display search engine friendly URLs, so instead of having a web address that looks like this:

The same post URL can display like this:

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

If you need help with permalinks, refer to this tutorial: Using Permalinks To Improve Your WordPress SEO

Step 2: Create A List Of Your Main Topics

Keeping your site’s content organized is important, as this will not only make it easier for your visitors to find the information they’re looking for, but can also help to boost your site’s optimization for better search engine results.

We recommend, therefore, first planning what kind of broad “topics” you will write about and publish on your website or blog. These can be topics related to your niche, your products or services, and even your industry.


For more information about planning a website, go here: A Money-Saving Guide To Website Planning For Non-Technical Business Owners

When creating a list of topics, 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 “authority” that online visitors will want to subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer to others.

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
  • Marriage Vows
  • etc.

Step 3: Select Relevant Category Names

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Technology”, etc…) is very hard to do, especially when you’re just starting out. It’s better to focus on building your authority in a niche, or segment of your market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see from the above Market > Niche > Sub niche hierarchy 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 deciding on 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 monthly searches for each of these keywords …

Use keyword research tools to help with category planning

(Keyword research - a useful tool for 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 content), and how to use these elements to gain a competitive advantage. If you set a strategic objective that is too big (i.e. trying to dominate the entire “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.

For tutorials on strategic online business online strategies like keyword research, identifying target audience demographics, etc., see this tutorial: How To Plan Your Business Website - A Practical Primer For Non-Technical 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 post categories.

Step 4: Set Up Categories

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

WordPress allows you to easily organize posts using categories

(WordPress allows you to easily organize posts by categories)

To access your WordPress Post Categories section, log into the WP admin section and select Posts > Categories

To add a new category, simply fill in the fields in the ‘Add New Category’ section as described below:

Post Categories panel - Add New Category area fields

(Categories panel – Add New Category area fields)

  1. Name – Type a concise 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 the category-related sections of your site.
  2. Slug – The “slug” refers to the words that display in the URL of all posts published under a 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 automatically create one for you using a lower case version of your category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website (explained further below).
  4. Description – Add a brief description of your category 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.

Click Add New Category to add the new category …

Removing Categories

Important Info

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

You can delete WordPress categories individually, or in bulk.

How To Delete Single Categories

To remove single categories, place your mouse over the category you want to delete and click Delete

WordPress post category - Delete


A window will pop up asking you to confirm the deletion. Click OK to proceed, or Cancel to abort …

Click 'OK' to proceed

(Click ‘OK’ to proceed)

Deleting Categories In Bulk

Let’s say that you import product data into your site containing many different categories (e.g. product manufacturers), and you want 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 Info

Important: Make sure that any posts that may be affected when unnecessary categories are deleted have been reassigned to an existing or new category. For more details on how to reassign categories in posts, go to this tutorial: How To Edit And Delete Posts In WordPress

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

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

Select/Deselect Categories

(Selecting/Deselecting Categories)

After selecting all of the entries to be deleted, select ‘Delete’ from the ‘Bulk Actions’ dropdown menu …

Editing Categories In WordPress

To edit a post category in WordPress, do this:

In your ‘Categories’ table, find the item that needs editing, then hover over the category title, and click the ‘Edit’ link …

Category table menu - Edit

(Category – Edit)

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

(WordPress category – Quick Edit)

(Quick Edit fields)


Important: Changing the category slug affects the URL of all posts published under 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, 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 – Useful Tip

All posts must be assigned to a category in WordPress. If you do not assign a post to a category, WordPress will attribute your post automatically to the default category “Uncategorized” …

'Uncategorized' WordPress category

(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 users and optimized for search engines too.

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

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 …

Change 'Uncategorized' category to something more meaningful to readers and search engines

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

Now, when new posts are published using the default WordPress category, the URL will make more sense to visitors and be more effective for SEO …

Note: The site used in the example above has been configured to display SEO-friendly URLs, with the Permalinks set to display posts as “domain/category/post title”. For more details on how to set up search engine-friendly URLs on your site, see this tutorial: Setting Up WordPress Permalinks
