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.

Adding, Editing & Deleting Categories In WordPressWordPress post categories can help to make finding information about similar topics on your site easier for visitors. Categories also help to keep you content organized and allow search engines to better index your WordPress site.

In this step-by-step 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 are not really 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 post URL display like this:

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

We have created a detailed tutorial on configuring permalinks here: How To Improve Your WordPress SEO With Permalinks

Step 2: List 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 looking for, but can also help to significantly boost your site’s optimization for improved SEO.

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

Important Info

We have written a detailed tutorial about planning a website 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 your visitors, prospects, and clients need to be better educated or informed about. This is very important in terms of establishing your business as an online authority that visitors will want to come back again to learn from and/or refer to others.

For example, let’s say that you want 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:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Locations
  • Marriage Vows
  • etc.

Step 3: Choose Relevant Category Titles

Dominating an entire market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is very difficult, especially when you’re just getting started. you have a better chance of getting somewhere by focusing 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 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 Google’s estimates for the average number of monthly searches for each of these keywords …

Use keyword research to help plan your categories

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

When planning category topics, 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 you are going to use these elements to try and gain a competitive advantage. If you set a goal that is too big (i.e. aiming to dominate the entire online “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.

If you need help with strategic online business planning like effective keyword research, identifying audience demographics, etc., visit this tutorial: The Web Site Planning Process: A Cost-Saving Primer 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 your keywords into categories and add them to your WordPress website or blog.

Step 4: Set Up Your WP Post Categories

Saving your posts under carefully planned categories helps to keep your content organized, provides online visitors with a better user experience, and helps to optimize your site for search engines.

Organize content with categories

(Organize posts using categories)

To access your WordPress Post Categories section, log into your WordPress site, then go to the navigation menu and click on Posts > Categories

Posts - Categories

(WordPress Posts Menu – Categories)

This opens the ‘Categories’ screen …

(Categories Section)

In this panel, you can create, edit, and remove categories, including inserting category descriptions and other information that can help to improve your website’s SEO.

How To Add Categories To WordPress

(Categories panel – Add New Category area)

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

Categories panel - Add New Category section fields

(Post Categories panel – Add New Category fields)

  1. Name – Use 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 display in all category-related sections of your website.
  2. Slug – The “slug” are the words that display in the URL of all posts published under a category. Your slug can be different from your 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 your category name.
  3. Parent – Ignore this field, unless you plan to create nested category hierarchies on your website.
  4. Description – Add 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.

Click Add New Category to add the new category …

Deleting WordPress Post Categories


Removing 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 Categories Individually

To remove a single category, hover over the category and click the ‘Delete’ link …

Deleting categories individually

(Deleting categories individually)

A warning message will appear asking you to confirm the deletion. Click OK to go ahead, or Cancel to stop …

Click 'OK' to proceed

(Click ‘OK’ to proceed)

How To Delete Multiple WordPress 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 single category. If there are too many categories to delete one at a time, this is where the bulk delete feature can be useful.


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

To delete multiple WordPress categories, click on the main checkbox in the header row. This will select all category items on the page.

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

Once you have ticked all the items you want to delete, select the ‘Delete’ option from the ‘Bulk Actions’ drop menu …

How To Edit Post Categories

To edit a WordPress post category, do this:

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

(Edit link)

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

(Quick Edit link)

Quick Edit fields

(Quick Edit screen)

Useful Information

Changing the category slug will change the URL of posts published under that category. This can lead to “page not found” errors when visitors click on links 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 posts and pages have already been indexed in the search engines.

WordPress Category – Special Tip

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

Post category - 'Uncategorized'

(’Uncategorized’ category)

Useful Info

The default category cannot be deleted.

Having posts attributed to the ‘Uncategorized’ category 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 relevant to your readers and better for search engines too.

Hover over the “Uncategorized” entry and click on the ‘Quick Edit’ link …

Category: Uncategorized - Quick Edit

(Category menu: Uncategorized – Quick Edit)

Change both 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” 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 users and search engines)

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

(Use SEO-friendly URLs)

Note: The above site 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 SEO-friendly URLs on your site, see this tutorial: Using Permalinks To Improve Your WordPress SEO

Step 5 – Use WordPress Categories Effectively

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 tips for getting the most benefit from using categories.

Choose Relevant Keywords For Your Post Titles

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

So, for example, an article for an Outdoors Adventure Travel site focused on the ”Kayaking” niche could be titled “Kayaking In Europe – The 10 Most Insane Kayaking Adventures“.

Publish Your WordPress Posts Under Relevant Post Categories

Each time you add a new article or post, remember to select a category box before publishing your post …
