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 Set Up WordPress CategoriesWordPress categories help to make finding information on your site easier for visitors. Adding categories not only helps to organize your content, it also improves both your visitor’s search experience and your search engine rankings.

This tutorial helps you learn how to set up categories in posts.

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 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:

You can have the same post URL display like this:

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

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

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


If you need help with website planning, go here: 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 should be better educated or informed about. This is very important in terms of establishing your business as an online authority that visitors will want to subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer other people to.

Let’s say, for example, 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: Select Relevant Category Names

Dominating an entire market (i.e. “Weddings”, “Travel”, “Business”, etc…) is very difficult, especially if you’re just starting out. It’s better to focus on building your authority in a smaller niche, or micro niche of your main market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see in the above 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 selecting the keywords you would use as a top-level category to publish 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

(Google Keyword Planner – Keyword research 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 you are going to use these elements to try to a competitive advantage. If you set a strategic objective that is too big (i.e. aiming to dominate the entire “Wedding” market), you will only end up feeling disappointed. If, on the other hand, you focus on a narrow niche or sub-niche, you could experience little to no activity on your site and hence no significant opportunities to grow your business online.

For tutorials on online business areas like effective keyword research, identifying target 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 categories and add them to your WordPress site.

Step 4: Set Up Your WordPress Categories

Saving 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.

WordPress lets you easily organize your posts with categories

(Organize posts by categories)

To access your Categories area, log into your WordPress admin section, then go to your navigation menu and click on Posts > Categories

Posts - Categories

(Posts – Categories)

This opens the ‘Categories’ panel …

Post Categories Area

(WordPress Post Categories Area)

Here you can add, edit, and delete categories, including adding category descriptions and other information that can optimize your website or blog for search engines.

How To Add Post Categories

(WordPress Post 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 below:

Categories panel - Add New Category fields

(WordPress Post Categories screen – Add New Category 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 category. The 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 the category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website (explained further below).
  4. Description – Write 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 the 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 that were assigned to the deleted category will be reassigned to the WordPress default category (see further below).

How To Delete Multiple 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 would like to consolidate posts to a single category. 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 when unnecessary categories are deleted have been reassigned to an existing or new category. For more details on how to reassign post categories, see this tutorial: Editing And Deleting Posts

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

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

Important Info

Important: Modifying the category slug will affect the URL of all posts assigned for 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 – Useful Tip

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

Category - 'Uncategorized'

(’Uncategorized’ category)


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 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 Table Menu: Uncategorized - Quick Edit Link

(Quick Edit)

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 site readers and search engines

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

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

(Use SEO-friendly URLs)

Note: The site used in the example above has been configured to display search engine-friendly URLs, with the Permalinks set to display posts as “domain/category/post title”. If you need help setting up search engine-friendly URLs, see this tutorial: How To Change WordPress Permalinks

Step 5 – Using WordPress Categories Effectively

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

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

Choosing Relevant Keywords For Your Post Titles

In your content strategy, include the main keyword of your post in the title of your post, preferably near the beginning. This helps to optimize your post for search engines, and improves click through rates.

So, for example, an article on Outdoors Adventure Travel targeting the ”Kayaking” niche could be titled “Kayaking In Asia – The 5 Most Insane Kayaking Locations“.

Publish Your WordPress Posts Under Relevant Post Categories
