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.

Add, Edit, And Delete Post CategoriesWordPress post categories help to make finding information about similar topics on your site easier for visitors. Publishing posts under categories not only helps to organize your content, it also improves both your visitor’s experience and your search engine rankings.

This tutorial helps you learn about using post categories.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

By default, post URLs in WordPress aren’t really search engine friendly. In order to make the best use of 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 post link that looks like this:

You can have the post URL display like this:

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

We have written a detailed tutorial on permalinks here: How To Improve Your WordPress SEO Using SEO-Friendly URLs

Step 2: Make A List Of Topics

Maintaining 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.

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


To learn more about website planning, refer to this step-by-step tutorial: How To Plan A Website: A Basic Guide For Non-Technical Business Owners

When creating your list of topics, remember to include areas of your business that you believe your visitors, prospects, and clients should be better educated or informed about. This is important in terms of establishing your site as an “authority” that online visitors will want to subscribe to (if you offer a newsletter or valuable content like ongoing training, tips, etc.) and/or refer to others.

For example, let’s say that you want 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
  • Marriage Vows
  • etc.

Step 3: Select Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is very difficult, especially if you’re just starting out. It’s better to focus on trying to establish your authority in a niche, or subniche 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 take into account 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 these keywords …

Use keyword research to help plan your categories

(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 can control (like the keywords that will be used throughout your content), and how you are going to use these elements to try to a competitive advantage. If you set an unrealistic goal (i.e. aiming 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 microniche, you could experience little to no activity on your site and hence no significant opportunities to grow your business online.

For tutorials on strategic online business areas like effective keyword research, identifying target audience demographics, etc., see this tutorial: Planning Your Small Business Website - A Money-Saving Guide 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 your keywords into categories and add them to your WordPress website or blog.

Step 4: Set Up Categories

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

Organize your content using categories

(Organize posts by categories)

To access your WordPress Post Categories section, in your admin area, click on Posts > Categories

(Post Categories screen – Add New Category area fields)

  1. Name – Use 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” refers to the words that display in the URL of all posts published under a specific category. The 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 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 category description here. Some WordPress themes display this category description, and it can help with SEO. Your category description will be used for the category pages “meta” description.

Deleting WordPress Post Categories

Useful Info

Removing 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 (see further below).

You can delete categories individually, or in bulk.

How To Delete Categories Individually

To delete categories individually, hover over the category and a menu will display containing various options. Click the ‘Delete’ link to remove the category from your list …

(Delete link)

A message will pop up asking you to confirm the deletion. Click OK to permanently delete the item, or Cancel to abort …

Click 'OK' to delete the category

(Click ‘OK’ to delete the category)

How To Delete Multiple WordPress Categories

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 consolidate posts to a fewer number of categories. 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 by deleting unnecessary 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 A WordPress Post

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

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.

How To Edit Categories

To edit a WordPress category, do this:

In your ‘Categories’ panel, find the item that needs editing, then hover over the category name, and click Edit

Edit - Category

(Edit link – Category)

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

Changing the category slug affects the URL of posts assigned to that category. This can lead to “page not found” errors when visitors click on links to posts published elsewhere.

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 already been indexed in the search engines.

Post 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 assign your post to a default category called “Uncategorized” …

'Uncategorized' category

(Category – ‘Uncategorized’)


The default category cannot be deleted.

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

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

Category: Uncategorized - Quick Edit

(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 …

Step 5 – Use Post Categories Effectively

Optimizing content, categories, and post URLs helps to improve your site’s navigation and relevance in the search engines, which helps drive more visitors to your site.

Here are some additional tips for getting the most benefit when using categories.

Choose Relevant Keywords For Post Titles

As you create new content for your site, try to include the main keyword of your post in the title of your post, preferably at the beginning. This helps to optimize your page for search engines, and improves clickthrough rates.

So, for example, if writing a blog post for an Outdoors Adventure Travel site focused on the ”Kayaking” niche could be titled “Kayaking In America – 3 Remote Kayaking Locations“.

Publish Your WordPress Posts Under Relevant Post Categories

Each time you add a new article or post to your website or blog, remember to tick a relevant category box before publishing your post …
