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 …

Configuring CategoriesWordPress categories can help make finding information about similar topics 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 how to set up categories in WordPress posts in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

By default, post URLs in WordPress are not search engine friendly. In order to make the best use of WordPress categories, you will 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 look like this:

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

To learn more about permalinks, refer to this step-by-step tutorial: Improve Your WordPress SEO Using SEO-Friendly URLs

Step 2: Create A List Of Your Main Topics

Maintaining your 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 to significantly boost your site’s optimization for improved search engine results.

We recommend, therefore, planning what kind of broad “topics” you will write about. 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: How To Plan Your Website - A Cost-Saving Blueprint For Non-Technical Business Owners

When creating a list of topics, remember to include areas of your business that you believe 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 subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer other people to.

For example, let’s say that you would like 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:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Planning
  • Commitment Ceremonies
  • and so on …

Step 3: Choose Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Technology”, etc…) is very difficult, especially when you’re just getting started. It’s better to focus on 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 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 …

Use keyword research tools to help plan your categories

(Use keyword research tools to help plan your categories)

When planning category titles, 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 to a competitive advantage. If you set an unrealistic goal (i.e. trying to dominate the entire online “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 business online.

If you need help with strategic online business online strategies like effective keyword research, identifying target audience demographics, etc., see this tutorial: A Cost-Saving 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 convert your keywords into post categories.

Step 4: Set Up WordPress Post Categories

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

WordPress allows you to easily organize your posts by categories

(WordPress lets you easily organize your posts with categories)

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

Posts Menu - Categories

(Posts Menu – Categories)

This opens the ‘Categories’ panel …

WP Post Categories Screen

(Categories Panel)

Here you can add, edit, and delete categories, including adding descriptions for categories and other information that can optimize your site for search engines.

How To Add Post Categories

Post Categories screen - Add New Category area

(Categories screen – Add New Category section)

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

Categories screen - Add New Category fields

(WordPress Post Categories panel – Add New Category fields)

  1. Name – Enter a short 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” refers to the words that display in the URL of all posts published under a specific 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 (explained further below).
  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 the ‘Add New Category’ button to add your new category …

Removing WordPress Categories


Deleting a category does not delete the 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 categories individually, or in bulk.

Deleting Single Categories

To remove categories individually, place your mouse over the category and a menu will display containing a range of options. Click the ‘Delete’ link to remove the category from your list …

How To Delete Categories In Bulk

Let’s say that you import product data into your WordPress site containing a large number of 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 one at a time, 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: Editing And Deleting A Post In WordPress

To delete multiple WordPress categories, click the main checkbox next to the ‘Name’ column title. This will select all category items on the page.

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

Useful Information

Modifying the category slug affects the URL of posts published under that category. This can lead to “page not found” errors when visitors click on links pointing 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 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 attribute your post to a default category called “Uncategorized” …

Post category - 'Uncategorized'

(’Uncategorized’ WordPress category)

Important Info

The default category cannot be deleted.

Publishing posts under 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 meaningful to your readers and better for search engines too.

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

Quick Edit Link

(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 an extra SEO boost …

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

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

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

Use SEO-friendly URLs
