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 Categories In PostsWordPress categories can help make finding information on your site easier for visitors. Categories also help to organize your content and allow search engines to better index your WordPress site.

Learn how to configure and use categories in WordPress posts in this tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

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

If you need help with setting up and using permalinks, refer to this tutorial: Using Permalinks To Improve Your WordPress SEO

Step 2: List Your Topics

Keeping your content organized at all times 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 search engines to better index your content.

We recommend, therefore, planning what kind of broad “topics” you will write about. These can be topics related to your specific niche, your business, your industry, etc.

When creating your 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 important in terms of establishing your site as an online authority that visitors will want to come back repeatedly to and/or refer to others.

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
  • etc.

Step 3: Choose Relevant Category Names

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Sports”, etc…) is very difficult, especially if you’re just getting started. you have a better chance of getting somewhere by trying to build your authority in a smaller niche, or a subset of your market.

Take a look at the illustration below …

How To Add, Edit And Delete WordPress Categories

You can see from the above Market > Niche > Sub niche 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 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 estimates from Google for the average number of online searches performed each month for each of these keywords …

Use keyword research to help plan your categories

(Google Keyword Planner – Useful keyword research for 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 you are going to use these elements to try and gain a competitive advantage. If you set an unrealistic goal (i.e. dominating the online “Wedding” market), you will only end up feeling disappointed. If, on the other hand, you focus on a very narrow niche or microniche, you could experience little to no activity on your site and hence no significant opportunities to grow your business online.

If you need help with strategic online business areas like effective keyword research, identifying audience demographics, etc., refer to this tutorial: A Practical Guide To Web Site Planning For Business Owners

After mapping out your top-level topics and figuring out what your main keywords are, the next step is to turn these keywords into categories and add them to your WordPress site.

Step 4: Set Up Post Categories

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

Organize your content by categories

(Organize your content by categories)

To access your Post Categories area, go to your WP administration area and click on Posts > Categories

(Categories screen – Add New Category section fields)

  1. Name – Type 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” are the words that display in the URL of all posts published under a specific category. Your 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 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 hierarchies of categories on your website (explained further below).
  4. Description – Add 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.

To learn how to create and edit posts in WordPress, see these step-by-step tutorials:

Removing Categories


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

You can delete WordPress categories individually, or in bulk.

Deleting A Single Category

To delete categories individually, place your mouse over the category and click the ‘Delete’ link …

WordPress post category table - Delete link

(Deleting single categories)

A message will pop up in your browser asking you to confirm the deletion. Click OK to go ahead, or Cancel to stop …

Click 'OK' to delete the category

(Click ‘OK’ to proceed)

How To Delete Categories In Bulk

Let’s say that you import product data into your WordPress site containing many different categories (e.g. an e-commerce catalog), and you want to reduce the number of categories by assigning your imported posts to a single category. If there are 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 by deleting categories have been reassigned to an existing or new category. For more details on how to reassign categories in posts, go to this tutorial: Editing And Deleting Posts

To bulk delete WordPress categories, click the main checkbox next to the ‘Name’ column title. This will select all 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.

Important Info

Important: Changing the category slug changes the URL of posts published under that category. This can lead to “page not found” errors when visitors click on links pointing to posts that have already been indexed by search engines.

For this reason, it’s best to invest time into planning your categories before publishing content, and avoid changing the post category slug afterward if at all possible, especially after your posts and pages have been indexed in the search engines.

Post Category – Special 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 the default category “Uncategorized” …

Post category - 'Uncategorized'

(Post category – ‘Uncategorized’)


The default category cannot be deleted.

Having posts attributed to 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 visitors and optimize it better for search engines too.

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

Category Table: Uncategorized - Quick Edit

(Quick Edit)

Change 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 an extra SEO boost …

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

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

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

Use SEO-friendly URLs

(SEO improved URLs)

Note: The site used in the example above has been configured to display search engine-friendly URLs, with the Permalinks set to display posts as “domain/category/post title”. If you need help setting up search engine-friendly URLs on your site, see this tutorial: Changing WordPress Permalinks
