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

Learn how to set up categories in WP posts in this tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Out of the box, WordPress post URLs aren’t 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 SEO-friendly URLs, so instead of having a post link that looks like this:

You can have the same post URL look like this:

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

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

Step 2: List Your 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 looking for, but can also help search engines to better index your content.

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

Important Info

To learn more about website planning, see this step-by-step tutorial: The Web Site Planning Process: A Money-Saving Primer For Non-Technical Business Owners

When creating a 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 online authority that visitors will want to come back repeatedly to 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 Tips
  • Commitment Ceremonies
  • etc.

Step 3: Choose Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is very difficult, especially if you’re just getting started. you have a better chance of getting somewhere by trying to establish your authority in a niche, or a sub niche of your market.

Take a look at the illustration below …

How To Add, Edit And Delete WordPress Categories

You can see in the above Market > Niche > Sub niche hierarchy 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 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 …

Use keyword research tools to help plan your categories

(Keyword research - a useful tool for category planning)

When planning your category topics, it’s important to spend time thinking carefully about all the elements you can control (like the main keywords used throughout your site), and how to use these elements to try and 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 microniche, you could experience little to no activity on your site and hence no significant opportunities to grow your market share online.

For tutorials on strategic online business online strategies like effective keyword research, identifying audience demographics, etc., see this tutorial: A Practical Guide To Web Site Planning For 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 WordPress post categories.

Step 4: Set Up Your WP Post Categories

Publishing your posts under carefully planned categories helps to keep your content organized, provides online visitors with a better user experience, and helps to optimize your content for search engines.

Organize your posts using categories

(Organize posts by categories)

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

WP Posts Menu - Categories

(WP Posts Menu – Categories)

This opens the ‘Categories’ screen …

(WP Post Categories Section)

In this area, you can add, edit, and delete categories, including adding category descriptions and other information that can help to optimize your website for search engines.

Adding Categories

Categories panel - Add New Category

(Post Categories screen – Add New Category)

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

Post Categories screen - Add New Category area fields

(Categories screen – Add New Category area 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 then display in all 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. Your slug can be different than 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.
  4. Description – Add a brief category description here. Some WordPress themes display this category description, and it can help with SEO. WordPress uses the category description you write here for your category pages “meta” description.

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

How To Delete Categories

Useful Information

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 (this is covered further below).

You can delete categories individually, or in bulk.

Deleting A Single Category

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

How to delete categories individually

(Deleting an individual category)

A message will appear in your browser asking you to confirm the deletion. Click OK to proceed, 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 would like to reduce the number of existing categories by assigning your imported posts to a fewer number of categories. If you have too many categories to delete individually, this is where the bulk delete feature can be useful.

Useful Information

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 reassigning post categories, see this tutorial: Editing And Deleting Posts

To bulk delete categories, click on the main check box in the header row. This will select all category listings on the page.

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

Editing WordPress Post Categories

To edit a post category, do the following:

In your ‘Categories’ section, find the category to be edited, then hover over the category title, and click the ‘Edit’ link …

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

You can also edit information in a category using the Quick Edit option. Hover over the category title you want to edit and click on Quick Edit

Category - Quick Edit

(Quick Edit)

Edit your details and click on the ‘Update Category’ button to save your changes …

(Category – Quick Edit screen)

Important Info

Modifying the category slug changes 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, 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 a default category called “Uncategorized” …

'Uncategorized' WordPress post category

(’Uncategorized’ WordPress post category)


The default category cannot be deleted.

Attributing 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 relevant to your readers and optimized for search engines too.

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

Quick Edit Link

(Quick Edit link)

Change the Category Name and Category Slug to a keyword or keyword phrase that will be generally 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” to give your site a little extra SEO boost …

Change 'Uncategorized' category to something more meaningful to your users and search engines

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

Now, when posts are published using the default WordPress category, the URL will make more sense to visitors and be more effective for SEO …

Use search engine-friendly URLs

(SEO improved URLs)

Note: The site used in the example above has been configured to display SEO-friendly URLs, with the Permalinks set to display posts as “domain/category/post title”. To learn how to set up search engine-friendly URLs on your site, see this tutorial: Configuring Your WordPress Permalinks

Post Categories – Additional Information

Let’s take a look at some additional features of categories:

Multiple WordPress Post Categories

Step 5 – Use Categories Effectively

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

To optimize your site further, here are some additional tips for getting the most benefit from using categories.

Choosing Relevant Keywords For Your Post Titles

As you create new content for your site, always try to include the main keyword of your post in the title, preferably near the beginning. This helps to optimize your post for search engines, catch your visitor’s attention.

So, for example, if writing a blog post for an Outdoors Adventure Travel site targeting the ”Kayaking” niche could be titled “Kayaking In America – 7 Memorable Kayaking Adventures“.

Publish Posts Under Relevant Categories

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