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 CategoriesWordPress post categories help make finding information about similar topics on your site easier for visitors. Publishing posts under categories also helps search engines to better index your WordPress site.

Learn about configuring post categories in WordPress in this tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Default WordPress post web addresses 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 WordPress to display search engine friendly URLs, so instead of having a post link 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 first before configuring your categories.

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

Step 2: List Your Topics

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

The first step, then, is to carefully work out what kind of broad “topics” you will be publishing on your website or blog. These can be topics related to your niche, your services or products, your industry, etc.


To learn more about website planning, see this step-by-step tutorial: Planning Your Small Business Website: A Money-Saving Blueprint For Business Owners

When creating your list of topics, include areas of your business that you believe your visitors, prospects, and clients should be better educated or informed about. This is very important in terms of establishing your site as an online authority that visitors will want to subscribe to (if you offer a newsletter or valuable content like 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 the following:

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

Step 3: Select Relevant Category Titles

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 focusing on establishing your authority in a niche, or a sub niche 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 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 “Weddings” market (another category).

When deciding on 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 the above keywords …

Google Keyword Planner - Useful keyword research tool for category planning

(Use keyword research tools to help plan your categories)

When planning your category topics, 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 gain a competitive advantage. If you set a strategic objective that is too big (i.e. trying to dominate the online “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 grow your business online.

If you need help with strategic online business planning like keyword research, identifying target audience demographics, etc., visit this tutorial: The Website Planning Process Explained: A Money-Saving Primer 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 turn these into WordPress post categories.

Step 4: Set Up Your WordPress Categories

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

Organize posts with categories

(Organize content using categories)

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

Posts Menu - Categories

(Posts Menu – Categories)

This brings you to the ‘Categories’ screen …

(Post Categories Section)

In this area, you can create, edit, and delete categories, including inserting descriptions for categories and other information that can improve your site’s SEO.

Adding Post Categories

(Categories panel – Add New Category)

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

Categories screen - Add New Category fields

(Post Categories panel – Add New Category fields)

  1. Name – Type a concise 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 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 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 SEO. Your category description will be used for your category pages “meta” description.

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

How To Remove Categories In WordPress

Important Info

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

You can delete categories individually, or in bulk.

How To Delete Categories Individually

To delete a single category, place your mouse over the category and a menu will display containing various options. Click Delete to remove the category from your list …

Delete - WordPress category

(How to delete a single category)

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

Click 'OK' to delete the category

(Click ‘OK’ to proceed)

Deleting Multiple Categories

Let’s say that you import product data into your 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 fewer number of categories. If you have too many categories to delete one at a time, this is where the bulk delete feature comes in handy.

Useful Information

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

To delete multiple categories, click on the main checkbox in the header row. This will select all category items on the page.

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

How To Edit Post Categories In WordPress

To edit a WordPress post category, do this:

Go to your ‘Categories’ panel, locate the category entry that needs editing, then hover over the category name, and click Edit


(WordPress post category menu – Edit)

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

You can also edit categories using the Quick Edit option. Hover over the category title you would like to edit and click on Quick Edit

Quick Edit link

(Quick Edit link)

Quick Edit fields

(Quick Edit fields)


Modifying the category slug will change the URL of all posts assigned to 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, we recommend investing 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

All posts must be assigned to categories in WordPress. If you do not assign a post to a category, WordPress will assign your post automatically to “Uncategorized” …

'Uncategorized' category

(WordPress category – ‘Uncategorized’)

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 unassigned posts as “uncategorized”, let’s make the category a little more meaningful 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 …

Quick Edit

(Category menu: Uncategorized – Quick Edit)

Change the Category Name and Category Slug to a keyword or keyword phrase that will be relevant to the main 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 …

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

Now, when 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
