How To Configure And Use Categories In PostsWordPress categories can help to make finding information about similar topics on your site easier for visitors. Categories also help to organize your content and allow search engines to better index your WordPress site.

Learn about configuring categories in WP posts in this tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Default WordPress post URLs aren’t search engine friendly. In order to make the best use of 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 same post URL display 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 configuring and using permalinks, see this step-by-step tutorial: Improve Your WordPress SEO Using Permalinks

Step 2: Create A List Of Your Main 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 searching for, but can also help to significantly boost your site’s optimization for better search engine results.

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

When creating a list of topics, include areas of your business that your visitors, prospects, and clients should 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 subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer to others.

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:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Locations
  • Commitment Ceremonies
  • etc.

Step 3: Select Relevant Category Titles

Dominating an entire market (i.e. “Weddings”, “Travel”, “Technology”, etc…) is extremely difficult, especially if you’re just starting out. It’s better to focus on trying to establish your authority in a smaller niche, or sub niche of your main 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 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 - a useful tool for category planning

(Google Keyword Planner – Keyword research for category planning)

When planning your topic categories, it’s important to take your time and think carefully about all the elements you can control (like the keywords that will be used throughout your site), and how to use these elements to 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 sub-niche, you could experience little to no activity on your site and hence no significant opportunities to grow your market share online.

For tutorials on online business online strategies like effective keyword research, identifying target audience demographics, etc., see this tutorial: How To Plan Your Website - A Useful 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 Post Categories

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

WordPress lets you easily organize content by categories

(Organize content using categories)

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

(Categories screen – Add New Category)

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

Categories panel - Add New Category fields

(WP Post Categories screen – Add New Category section 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 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 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 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 category hierarchies on your site.
  4. Description – Write a brief category description here. Some WordPress themes display this category description, and it can help with search engine optimization. Your category description will be used for the category pages “meta” description.

How To Delete 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 (see further below).

You can delete WordPress categories individually, or in bulk.

Deleting Single Categories

To remove an individual category, place your mouse over the category and click Delete

Deleting a single category

(How to delete an individual category)

A warning message will pop up asking you to confirm the deletion. Click OK to proceed, or Cancel to abort …

Click 'OK' to proceed

(Click ‘OK’ to proceed)

Deleting 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 existing 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 comes in handy.


Important: Make sure that any posts that will be affected when unnecessary categories are deleted have been reassigned to an existing or new category. For more details on reassigning post categories, go to this tutorial: How To Edit And Delete Posts

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

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

How To Edit Categories

To edit a WordPress category, do the following:

Go to your ‘Categories’ screen, find the category that needs to be edited, then place your mouse over the category title, and click the ‘Edit’ link …

Edit link - WordPress category

(Category table – Edit)

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

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 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.

WordPress Categories – Special 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 automatically to a default category called “Uncategorized” …

WordPress category - 'Uncategorized'

(’Uncategorized’ post category)

Important 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 posts as “uncategorized”, let’s make the category a little more meaningful to your site users and better for search engines too.

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

Quick Edit

(Category table: Uncategorized – Quick Edit)

Change 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 …
