Learn what categories are, how to use categories to improve your content navigation and SEO, and how to add, edit, and delete WordPress categories.

Landing Pages for WordPress

How To Set Up Post CategoriesWordPress categories help to make finding information on your site easier for visitors. Publishing posts under categories not only helps to keep your content organized, it also improves both your visitor’s search experience and your search engine rankings.

Learn about adding, editing, and deleting categories in this tutorial.

Step 1: Configure Your Permalinks

Default WordPress post URLs are not very search engine friendly. In order to make the best use of 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 web address that looks like this:

You can have the same post URL look like this:

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

Step 2: List Your Main Topics

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

The first step, then, is to work out what kind of broad “topics” you will be writing about. These can be topics related to your niche, your products or services, or your industry.


For a detailed step-by-step tutorial on planning a website, go here: The Website Planning Process: A Money-Saving Primer For Business Owners

When creating a 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 site 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.

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

Step 3: Select Relevant Category Names

Dominating an entire market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is extremely hard, especially when you’re just getting started. you have a better chance of getting somewhere by trying to build your authority in a niche, or a subset 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 subniche (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 plan your categories

(Keyword research can help you with category planning)

When planning your topic categories, it’s important to take your time and think carefully about all the elements you can control (like the main keywords used throughout your site), 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. dominating the entire “Wedding” market), you will only end up feeling disappointed. If, on the other hand, you focus on a 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 areas like effective keyword research, identifying target audience demographics, etc., see this tutorial: A Comprehensive Guide To Website 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 into categories and add them to your WordPress website or blog.

Step 4: Set Up Your WP Categories

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

Organize content by categories

(Organize content with categories)

To access your Post Categories section, go to your admin area and select Posts > Categories

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

(Categories panel – Add New Category fields)

  1. Name – Type 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 then 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 using a lower case version of the 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 description of your category here. Some WordPress themes display this category description, and it can help with SEO. WordPress uses the category description you write here for your category pages “meta” description.

How To Remove Categories In WordPress


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

You can delete categories individually, or in bulk.

Deleting Single Categories

To remove a single category, hover over the category and click Delete

Delete link - WordPress category

(Delete – Category)

A 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 delete the category

(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. product manufacturers), and you would like to reduce the number of categories by assigning your imported 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.

Useful Information

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

To delete multiple categories, click the main checkbox in the header row. This will select all category entries .

Next, go through the list 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.

How To Edit Categories

To edit a post category in WordPress, do the following:

Go to your ‘Categories’ table, find the category that needs to be edited, then hover over the category title, and click Edit

WordPress post category table - Edit

(Edit link)

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

'Edit Category' panel

(‘Edit Category’ section)

You can also edit information in categories using the Quick Edit option. Hover over the category title you want to edit and click on Quick Edit

WordPress category - Quick Edit

(WordPress category table menu – Quick Edit link)

Edit your details and click Update Category to save your changes …

Category - Quick Edit fields

(Category menu – Quick Edit fields)


Changing the category slug will change the URL of posts assigned to 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 category slug afterward if at all possible, especially after your site is established.

WordPress Categories – 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 a default category called “Uncategorized” …

'Uncategorized' post category

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

Hover over the “Uncategorized” entry and click on Quick Edit

Quick Edit Link

(Category menu: Uncategorized – Quick Edit link)

Change 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” to give your site an extra SEO boost …

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

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

Optimizing content, categories, and search engine and visitor friendly URLs helps to increase 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.

Choose Keyword-Relevant Post Titles

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