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 And Use Categories In PostsWordPress post categories help make finding information about similar topics on your site easier for visitors. Categories also help search engines to better index your WordPress site.

Learn how to set up WordPress categories in this tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Default WordPress post web addresses are not very search engine friendly. In order to make the best use of 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 web address that looks like this:

The same post URL can look like this:

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

Step 2: List Your Topics

Maintaining your site’s 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 SEO.

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

When creating a list of topics, remember to include areas of your business that you believe your visitors, prospects, and clients need to be better educated or informed about. This is very important in terms of establishing your website as an “authority” that online visitors will want to come back again to learn from and/or refer to others.

Let’s say, for example, that you would like 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 the following:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Planning
  • Marriage Vows
  • etc.

Step 3: Choose Relevant Category Headings

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Sports”, etc…) is extremely hard, especially if you’re just getting started. It’s better to try and establish your authority in a smaller niche, or micro niche of your market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see from 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 choosing 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 these keywords …

Use keyword research tools to help plan your categories

(Use keyword research tools to help with category planning)

When planning your category names, 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 too big a goal (i.e. dominating the online “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 increase your market share online.

If you need help with strategic online business planning like effective keyword research, identifying target audience demographics, etc., refer to this tutorial: Planning A Web Site - A Basic Blueprint For Non-Technical Business Owners

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

Step 4: Set Up Your Categories

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

WordPress lets you easily organize your posts with categories

(Organize posts using categories)

To access your Post Categories section, in the Dashboard, select Posts > Categories

Posts Menu - Categories

(Posts – Categories)

This opens the ‘Categories’ screen …

Categories Section

(Categories Panel)

This area allows you to add, edit, and delete categories, including adding descriptions for categories and other information that can help to improve your site’s SEO.

How To Add Categories

Categories panel - Add New Category

(Categories screen – Add New Category section)

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

Categories panel - Add New Category area fields

(WP Post Categories screen – Add New Category fields)

  1. Name – Type 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 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 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 description of your category here. Some WordPress themes display this category description, and it can help with SEO. Your category description will be used for the category pages “meta” description.

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

How To Delete Post Categories

Important Info

You can delete categories individually, or in bulk.

Deleting Single Categories

To remove categories individually, hover over the category you would like removed and click Delete

Deleting single categories

(Delete – WordPress post category menu)

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

(Click ‘OK’ to delete the category)

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 would like to consolidate posts to a fewer number of categories. If you have too many categories to delete one at a time, this is where the bulk delete feature can be useful.

Important Info

Important: Make sure that any posts that may be affected when categories are removed have been reassigned to an existing or new category. For more details on how to reassign post categories, visit this tutorial: Editing And Deleting Posts

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

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

(Quick Edit – Category table menu)

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

(Category table menu – Quick Edit fields)

Important Info

Important: Changing the category slug will change the URL of posts assigned to that category. This can lead to “page not found” errors when visitors click on links pointing to posts published elsewhere.

For this reason, we strongly recommend investing 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 been indexed in the search engines.

Post Category – Special Tip

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

'Uncategorized' post category

(’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 unassigned 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 …

Category Table Menu: Uncategorized - Quick Edit Link

(Category: Uncategorized – Quick Edit link)

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

Change 'Uncategorized' category to something more meaningful to site visitors and search engines

Step 5 – Using Post 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.

To further improve your results, here are some tips for getting the most benefit when using post categories.

Choosing Keyword-Relevant Post Titles

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

So, for example, an article for an Outdoors Adventure Travel business targeting the “Winter Camping” niche could be titled “Winter Camping Tips – 3 Essential Survival Accessories Everyone Needs For A Safe Winter Camping Adventure“.

Publish Posts Under The Most Relevant Post Category
