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 Configure And Use WordPress CategoriesWordPress categories can help make finding information on your site easier for visitors. Filing posts under categories also helps to organize your content and allows search engines to better index your WordPress site.

Learn about adding, editing & deleting WordPress categories in this tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

By default, WordPress 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 allow your WordPress site to 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 now before configuring your post categories.

We have created a detailed tutorial on configuring permalinks here: Improve Your WordPress SEO Using SEO-Friendly URLs

Step 2: Create A List Of Topics

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

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


We have written a detailed tutorial about website planning here: The Website Planning Process Explained - A Basic Guide For 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 “authority” that online visitors will want to come back repeatedly to 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
  • etc.

Step 3: Select Relevant Category Names

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is very difficult, especially when you’re just getting started. It’s better to try and build your authority in a smaller niche, or a subniche of your main market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see in the above Market > Niche > Subniche 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 choosing the keywords you would use as a top-level category to publish your posts under, it’s a good idea to consider factors like “market competition.”

For example, the screenshot below shows estimates from Google for the average number of online searches performed each month for each of the sample keywords …

Keyword research can help you with category planning

(Keyword research can help you with category planning)

When planning your main topic categories, it’s important to spend time thinking carefully about all the elements you can control (like the keywords that will be used throughout your content), and how to use these elements to try and gain a competitive advantage. If you set a goal that is too big (i.e. trying to dominate 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 strategic online business areas like keyword research, identifying audience demographics, etc., see this tutorial: The Website Planning Process Explained - A Money-Saving Guide For 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 Your Post Categories

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

WordPress lets you easily organize posts by categories

(Organize content by categories)

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

WP Posts Menu - Categories

(WordPress Posts Menu – Categories)

This opens the ‘Categories’ screen …

(Categories Section)

In this panel, you can create, edit, and delete categories, including adding descriptions for categories and other information that can help to improve your site’s SEO.

(Post Categories panel – Add New Category)

To add a new category, complete the fields in the ‘Add New Category’ section as per the example below:

Categories panel - Add New Category fields

(Categories screen – 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 website.
  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 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 the category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website.
  4. Description – Write a brief category description 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.

Click the ‘Add New Category’ button when done to add the new category …

How To Remove Post Categories

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

You can delete categories individually, or in bulk.

Deleting Single Categories

To remove categories individually, hover over the category and a menu will display containing a range of options. Click Delete to delete the category from your list …

Deleting an individual category

How To Delete Multiple Categories

Let’s say that you import product data into your WordPress site containing a large number of categories (e.g. product manufacturers), and you want to reduce the number of categories by assigning your imported posts to a single category. If you have too many categories to delete individually, this is where the bulk delete feature comes in handy.


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

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

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

Important Info

Changing the category slug will affect 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, 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.

WordPress 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 automatically assign your post to a default category called “Uncategorized” …

WordPress category - 'Uncategorized'

(’Uncategorized’ post category)

Important Info

The default category cannot be deleted.

Having posts assigned 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 visitors and optimized for search engines too.

Place your mouse over the “Uncategorized” entry and click on the ‘Quick Edit’ link …

Category: Uncategorized - Quick Edit Link

(Category menu: Uncategorized – Quick Edit link)

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. 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 a little extra SEO boost …
