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 Post Categories In WordPressWordPress post categories help make finding information about similar topics on your site easier for visitors. Filing posts under categories also helps to organize your content and allows search engines to better index your WordPress site.

Learn about adding, editing, and deleting categories in WP posts in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

By default, post URLs 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 let you 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 yet configured your permalinks, then we recommend doing so now before configuring your post categories.

For a detailed tutorial on using permalinks, go here: How To Improve Your WordPress SEO Using Permalinks

Step 2: Make A List Of Your Main Topics

Maintaining 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 to boost your site’s optimization for better SEO.

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


For more information about planning a website, go here: A Cost-Saving Guide To Web Site Planning 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.

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 the following:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Locations
  • Commitment Ceremonies
  • and so on …

Step 3: Choose Relevant Category Headings

Dominating an entire market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is very difficult, especially if you’re just starting out. It’s better to focus on establishing your authority in a smaller niche, or a sub niche 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 Market > Niche > Subniche 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 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 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 above keywords …

Keyword research can help you with category planning

(Use keyword research to help plan your categories)

When planning category names, it’s important to take your time and think carefully about all the elements you have control over (like the keywords that will be used throughout your site), and how you are going to use these elements to gain a competitive advantage. If you set an unrealistic goal (i.e. trying to dominate the 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 increase your business online.

For tutorials on strategic online business online strategies like effective keyword research, identifying audience demographics, etc., see this tutorial: How To Plan Your Website - A Practical Blueprint 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 convert these into post categories.

Step 4: Set Up Categories

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

Organize content using categories

(WordPress lets you easily organize content by categories)

To access your WordPress Categories area, log into your WordPress site, then go to your navigation menu and select Posts > Categories

Posts - Categories

(Posts Menu – Categories)

This opens the ‘Categories’ panel …

WordPress Post Categories Section

(Categories Section)

This screen lets you create, edit, and remove categories, including adding category descriptions and other information that can help to optimize your site for search engines.

Adding WordPress Categories

Categories screen - Add New Category area

(Categories panel – Add New Category section)

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

WordPress Post Categories screen - Add New Category area fields

(Categories panel – Add New Category section 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 website.
  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 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 automatically create one for you 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 (explained further below).
  4. Description – Write a brief description of your category here. Some WordPress themes display this category description, and it can help with search engine optimization. WordPress uses the category description you write here for the category pages “meta” description.

Click Add New Category when done to add the new category …

Removing 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 default category (see further below).

You can delete categories individually, or in bulk.

How To Delete A Single Category

To remove categories individually, hover 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 table menu

(Deleting categories individually)

A message will appear in your browser asking you to confirm the deletion. Click OK to go ahead, or Cancel to abort …

Click 'OK' to delete the category

(Click ‘OK’ to proceed)

How To Delete WordPress Categories In Bulk

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 you have 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 when categories are deleted have been reassigned to an existing or new category. For more details on how to reassign categories in posts, see this tutorial: Editing And Deleting A Post In WordPress

To bulk delete categories, click on the main checkbox in the header row. This will select all items .

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.

Select/Deselect Categories

Useful Info

Modifying the category slug will affect the URL of all posts published under that category. This can lead to “page not found” errors when visitors click on links 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 post category slug afterward if at all possible, especially after your site is established.

WordPress Category – 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” …

WordPress post category - 'Uncategorized'

(’Uncategorized’ post category)


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

Hover over the “Uncategorized” entry and click on Quick Edit

Quick Edit Link

(Quick Edit link)

Change both the Category Name and Category Slug to a keyword or keyword phrase that will be generally 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 …

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

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

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

Use search engine-friendly URLs
