How To Set Up & Use WordPress CategoriesWordPress post categories help make finding information about similar topics on your site easier for visitors. Filing posts under categories also helps search engines to better index your WordPress site.

Learn how to set up & use categories in WordPress in this tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post web addresses aren’t 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 allow WordPress to display search engine friendly URLs, so instead of having a post link that looks like this:

The post URL can 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 permalinks, refer to this tutorial: How To Set Up Your WordPress Permalinks

Step 2: Create A List Of Your Main Topics

Keeping your site’s 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 to significantly boost your site’s optimization for better SEO.

The first step, therefore, is to plan what kind of broad “topics” you will be writing about. These can be topics related to your niche, your products or services, your industry, etc.


For a detailed step-by-step tutorial about website planning, go here: A Basic Guide To Web Site Planning For Non-Technical Business Owners

When creating your 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 web site as an “authority” that online 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 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:

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

Step 3: Select Relevant Category Topics

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Health”, etc…) is extremely difficult, especially when you’re just getting started. you have a better chance of getting somewhere by trying to build your authority in a niche, or a segment of your 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 monthly searches for each of the sample keywords …

Google Keyword Planner - Useful keyword research for category planning

(Use keyword research to help with category planning)

When planning category titles, it’s important to spend time thinking carefully about all the elements you have control over (like the main keywords used throughout your content), and how to use these elements to try to a competitive advantage. If you set too big a goal (i.e. dominating 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 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 areas like effective keyword research, identifying target audience demographics, etc., see this tutorial: A Money-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 categories and add them to your WordPress website or blog.

Step 4: Set Up Categories

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

Organize posts by categories

(Organize your content with categories)

To access your WordPress Categories section, go to the WP Dashboard and select Posts > Categories

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

Post Categories screen - Add New Category fields

(Categories screen – Add New Category area fields)

  1. Name – Enter a short 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 website.
  2. Slug – The “slug” are the words that display in the URL of all posts published under a 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 the category name.
  3. Parent – Ignore this field, unless you plan to create nested category hierarchies on your site (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 search engine optimization. WordPress uses the category description you write here for your category pages “meta” description.

How To Remove Post Categories In WordPress


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

Delete - Category table menu

(Deleting an individual category)

A warning message will pop up in your browser asking you to confirm the deletion. Click OK to permanently delete the item, or Cancel to stop …

Click 'OK' to delete the category

(Click ‘OK’ to proceed)

Deleting Multiple WordPress Categories

Let’s say that you import product data into your site containing a large number of categories (e.g. an e-commerce catalog), and you want to consolidate posts to a fewer number of categories. If you have too many categories to delete one at a time, this is where the bulk delete feature can be useful.


Important: Make sure that any posts that may be affected by deleting unnecessary categories have been reassigned to an existing or new category. For more details on how to reassign post categories, visit this tutorial: How To Edit And Delete Posts In WordPress

To bulk delete WordPress categories, click the main check box next to the ‘Name’ column title. This will select all category listings on the page.

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

(Edit link – Category table)

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

Changing the category slug affects the URL of posts assigned for 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 category slug afterward if at all possible, especially after your site is established.

WordPress Categories – Special Tip

In WordPress, all posts must be assigned to a category. If you do not assign a post to a category, WordPress will attribute your post to “Uncategorized” …

Category - 'Uncategorized'

(’Uncategorized’ category)

Important Info

The default category cannot be deleted.

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

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

Quick Edit Link

(Category: Uncategorized – 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.
