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 Categories In WordPress PostsWordPress categories can help make finding information 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.

Learn about adding, editing, and deleting post categories in WordPress in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

By default, post web addresses in WordPress are not search engine friendly. In order to make the best use of post categories, you will first need to modify the way WordPress displays your URLs.

Permalinks allow WordPress to display SEO-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 do so first before configuring your post categories.

We have created a detailed tutorial on setting up permalinks here: Using Permalinks To Improve Your WordPress SEO

Step 2: List Your Main Topics

Keeping your content organized 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 boost your site’s optimization for improved search results.

We recommend, therefore, planning what kind of broad “topics” you will write about and publish on your website or blog. These can be topics related to your specific niche, your business, and even your industry.


If you need help with planning a website, see this step-by-step tutorial: A Basic Guide To Web Site Planning For Business Owners

When creating your list of topics, remember to 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 site as an online authority that visitors will want to come back repeatedly to and/or refer to others.

Let’s say, for example, that you want 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
  • and so on …

Step 3: Choose Relevant Category Topics

Dominating an entire market (i.e. “Weddings”, “Travel”, “Technology”, etc…) is very difficult, especially if you’re just getting started. It’s better to try and establish your authority in a niche, or a segment of your market.

Take a look at the example 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 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 estimates from Google for the average number of monthly searches for each of the sample keywords …

Keyword research - a useful tool for category planning

(Keyword research - a useful tool for category planning)

When planning your topic categories, 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 gain a competitive advantage. If you set an unrealistic 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 sub-niche, you could experience little to no activity on your site and hence no significant opportunities to increase your business online.

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

Step 4: Set Up Your Post Categories

Saving 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 for search engines.

WordPress allows you to easily organize posts with categories

(WordPress lets you easily organize your posts using categories)

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

Here you can create, edit, and remove categories, including inserting descriptions for categories and other information that can optimize your website or blog for search engines.

(WP Post Categories screen – Add New Category section)

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

Categories panel - Add New Category fields

(Categories screen – Add New Category area fields)

  1. Name – Use 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 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 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 automatically using a lower case version of the category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories 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 your category pages “meta” description.

Deleting Post Categories


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

You can delete WordPress categories individually, or in bulk.

Deleting An Individual Category

To delete a specific category, place your mouse over the category you want removed and a menu will display containing various options. Click the ‘Delete’ link to delete the category from your list …

Delete link - Category

(Category table menu – Delete)

A window 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)

How To Delete Multiple Categories

Let’s say that you import product data into your site containing a large number of categories (e.g. product manufacturers), and you want to reduce the number of categories by assigning your imported posts to a fewer number of categories. If there are too many categories to delete one at a time, this is where the bulk delete feature comes in handy.


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 reassigning categories in posts, go to this tutorial: How To Edit And Delete Posts

To bulk delete categories, click on 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 deselect any 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 WordPress Post Categories

To edit a WordPress category, do the following:

In your ‘Categories’ screen, locate the item that you would like to edit, then hover over the category name, and click the ‘Edit’ link …

Edit - WordPress post category

(WordPress post category table – Edit)

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

(‘Edit Category’ section)

You can also edit a category using the Quick Edit option. Place your mouse over the category title you would like to edit and click on Quick Edit

Quick Edit - WordPress category

(Quick Edit – Category table menu)

(Quick Edit fields)


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

Categories – Useful 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 to a default category called “Uncategorized” …

'Uncategorized' WordPress category

(’Uncategorized’ post category)

Useful Information

The default category cannot be deleted.

Publishing posts under 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 relevant to your visitors and better for search engines too.

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

Category Table: Uncategorized - Quick Edit Link

(Category table: Uncategorized – Quick Edit link)

Change both 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” to give your site a little extra SEO boost …

Step 5 – Using WordPress Categories Effectively

Optimizing content, categories, and search-friendly URLs can help increase your site’s navigation and relevance in the search engines, which can help drive more visitors to your site.

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

Choose Relevant Keywords For Post Titles

SEO experts recommend including the main keyword of your post in your the title of your post, preferably near the beginning. This helps to optimize your page for search engines, and improves click through rates.

So, for example, an article on Outdoors Adventure Travel targeting the “Winter Camping” niche could be titled “Winter Camping Tips – 5 Survival Accessories Everyone Needs For A Safe Winter Camping Trip“.

Publish Your WordPress Posts Under The Most Relevant Post Category
