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 …

Add, Edit, And Delete WordPress CategoriesWordPress categories can 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 experience and your search engine rankings.

Learn about using WordPress post categories in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Out of the box, WordPress URLs aren’t search engine friendly. In order to make the best use of post 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 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 now before configuring your categories.

Step 2: List Your Main Topics

Maintaining your 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 search engines to better index your content.

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


If you need help with planning a website, see this tutorial: How To Plan Your Business Website: A Basic Primer For Non-Technical Business Owners

When creating a list of topics, remember to 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 website as an online authority that visitors will want to come back repeatedly to 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 Tips
  • Marriage Vows
  • and so on …

Step 3: Select Relevant Category Headings

Dominating an entire market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is extremely difficult, especially when you’re just starting out. you have a better chance of getting somewhere by focusing on establishing your authority in a niche, or micro niche of your market.

Take a look at the illustration below …

How To Add, Edit And Delete WordPress Categories

You can see in the above hierarchy 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 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 online searches performed each month for each of the above keywords …

Keyword research - a useful tool for category planning

(Keyword research can help you with 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 keywords that will be used throughout your site), and how to use these elements to gain a competitive advantage. If you set too big a goal (i.e. dominating the “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 increase your business online.

For tutorials on online business online strategies like keyword research, identifying audience demographics, etc., visit this tutorial: The Web Site Planning Process - A Comprehensive Blueprint 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 convert these into post categories.

Step 4: Set Up Categories

Publishing WordPress posts under carefully planned categories helps keep your content organized, provides your visitors with a better user experience, and helps to optimize your web pages for search engines.

Organize posts using categories

(WordPress lets you easily organize posts using categories)

To access your Categories area, in your Dashboard menu, select Posts > Categories

(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 display in all 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 automatically 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 site.
  4. Description – Add a brief description of your category here. Some WordPress themes display this category description, and it can help with SEO. Your category description will be used for the category pages “meta” description.

How To Remove Categories


Removing a category does not delete posts assigned to that category. Instead, any posts assigned to deleted categories 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 delete categories individually, hover over the category you would like to delete and a menu will display containing various options. Click the ‘Delete’ link to remove the category from your list …

(How to delete a single category)

A 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)

Deleting WordPress Categories In Bulk

Let’s say that you import product data into your site containing many different categories (e.g. an e-commerce catalog), 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 Info

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 how to reassign post categories, go to this tutorial: Editing And Deleting A Post

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

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

Editing Categories In WordPress

To edit a category, do the following:

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


(Category table menu – Edit)

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

Modifying 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 that have already been indexed by search engines.

For this reason, we strongly 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 – Useful Tip

All posts must be assigned to a category 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'

(Category – ‘Uncategorized’)

Useful 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 users and optimized for search engines too.

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

Quick Edit

(Quick Edit)

Change both the Category Name and Category Slug to a keyword or keyword phrase that will be relevant to the overall topic of your site.
