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 …

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

In this tutorial, you will learn about adding, editing, and deleting WordPress categories.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Out of the box, WordPress post URLs 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 allow your WordPress site to display SEO-friendly URLs, so instead of having a web address that looks like this:

You can have the same post URL display like this:

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

We have created a detailed tutorial about configuring and using permalinks here: Using Permalinks To Improve Your WordPress SEO

Step 2: Create A List Of 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 significantly boost your site’s optimization for better search engine results.

We recommend, therefore, first planning what kind of broad “topics” you will publish on your site. These can be topics related to your specific niche, your business, your industry, etc.

Useful Info

We have written a detailed tutorial on website planning here: The Website Planning Process: A Practical Guide For Business Owners

When creating your list of topics, 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 “authority” that online visitors will want to subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer to others.

Let’s say, for example, that you want to start a site 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 Topics

Dominating an entire market (i.e. “Weddings”, “Travel”, “Fashion”, etc…) is extremely hard, 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 sub niche of your 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 deciding on the keywords you would use as a top-level category to publish 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 …

Google Keyword Planner - Keyword research for category planning

(Keyword research can help you with category planning)

When planning your main topic categories, 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 to use these elements to try to 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 market share online.

Once you have mapped out your top-level topics and figured out what your main keywords are, the next step is to convert these keywords into post categories.

Step 4: Set Up Your WP Categories

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

Organize posts with categories

(WordPress lets you easily organize posts using categories)

To access your WordPress Categories section, in the Dashboard, choose Posts > Categories

Posts - Categories

(Posts Menu – Categories)

This opens the ‘Categories’ screen …

Categories Section

(WordPress Post Categories Panel)

This panel allows you to create, edit, and delete categories, including inserting category descriptions and other information that can help to improve your website’s SEO.

Adding Post Categories To WordPress

(Post Categories panel – Add New Category area)

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

Categories screen - Add New Category area fields

(Categories screen – Add New Category area fields)

  1. Name – Type 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 site.
  2. Slug – The “slug” are 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 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 site.
  4. Description – Write a brief description of your category 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.

Let’s say that you import product data into your site containing many different categories (e.g. product manufacturers), and you want to reduce the number of categories by assigning your imported 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 by deleting unwanted categories have been reassigned to an existing or new category. For more details on reassigning post categories, go to this tutorial: Editing And Deleting A WordPress Post

To delete multiple categories, click the main check box next to the ‘Name’ column title. This will select all category entries on the page.

Important: Changing the category slug changes the URL of all 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 category slug afterward if at all possible, especially after your posts and pages have been indexed in the search engines.

WordPress Post 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 automatically to “Uncategorized” …

Category - 'Uncategorized'

(Post category – ‘Uncategorized’)

Useful Information

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 site readers and better for search engines too.

Hover over the “Uncategorized” entry and click on the ‘Quick Edit’ link …

Category Table Menu: Uncategorized - Quick Edit Link

(Category table menu: Uncategorized – Quick Edit link)

Change both the Category Name and Category Slug to a keyword or keyword phrase that will be generally relevant to the overall topic of your site.
