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 CategoriesWordPress categories can help to make finding information on your site easier for visitors. Categories also help to keep you content organized and allow search engines to better index your WordPress site.

In this step-by-step tutorial, you will learn about configuring WordPress categories.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post web addresses aren’t very 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 web address that looks like this:

The post URL can display like this:

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

We have created a detailed tutorial on configuring permalinks here: Changing Your WordPress Permalinks

Step 2: List Your Topics

Keeping your site’s 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 search results.

The first step, then, is to carefully plan what kind of broad “topics” you will publish on your site. These can be topics related to your niche, your business, or your industry.

Important Info

We have created a detailed tutorial on planning a website here: How To Plan Your Small Business Website - A Basic Blueprint 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 very important in terms of establishing your site 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 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:

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

Step 3: Choose Relevant Category Titles

Dominating an entire market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is extremely hard, especially if you’re just starting out. It’s better to try and establish your authority in a smaller niche, or a subniche 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 “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 monthly searches for each of these keywords …

Use keyword research tools to help plan your categories

(Use keyword research to help with category planning)

When planning your category titles, 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 to use these elements to try to a competitive advantage. If you set too big a goal (i.e. trying to dominate 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 increase your business online.

For tutorials on online business planning like effective keyword research, identifying target audience demographics, etc., see this tutorial: The Website Planning Process Explained - A Money-Saving Guide For Business Owners

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

Step 4: Set Up Post Categories

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

Organize posts using categories

(WordPress allows you to easily organize posts by categories)

To access your WordPress Categories section, in your main menu section of your admin area, click on Posts > Categories

WP Posts Menu - Categories

(Posts Menu – Categories)

This opens the ‘Categories’ panel …

Categories Area

(WordPress Post Categories Area)

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

How To Add Categories

WordPress Post Categories panel - Add New Category

(Categories screen – Add New Category)

To create a new post category in WordPress, complete the fields in the ‘Add New Category’ section as per the example below:

Categories screen - Add New Category fields

(Categories screen – Add New Category area fields)

  1. Name – Enter a concise 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 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 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 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 site (explained further below).
  4. Description – Add a brief category description 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 the ‘Add New Category’ button to add the new category …

Deleting WordPress Post Categories


Deleting a category does not delete the posts assigned to that category. Instead, posts that were assigned to deleted categories will be reassigned to the WordPress default category (this is covered further below).

You can delete categories individually, or in bulk.

Deleting Categories Individually

To delete categories individually, place your mouse over the category and a menu will display containing various options. Click the ‘Delete’ link to remove the category from your list …

Delete link - Category table

(Category table menu – Delete)

A window will pop up asking you to confirm the deletion. Click OK to go ahead, or Cancel to stop …

Click 'OK' to delete the category

(Click ‘OK’ to delete the category)

Deleting Multiple Categories

Let’s say that you import product data into your WordPress site containing many different categories (e.g. product manufacturers), and you want to reduce the number of existing categories by assigning your imported posts to a single category. If you have too many categories to delete individually, this is where the bulk delete feature comes in handy.

Important Info

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 categories in posts, see this tutorial: How To Edit And Delete Posts

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

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

How To Edit Categories

To edit a category in WordPress, do the following:

Go to your ‘Categories’ table, locate the category entry that you would like to edit, then hover over the category title, and click the ‘Edit’ link …

Category table - Edit

(Edit – Category table)

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

You can also edit categories using the Quick Edit option. Hover over the category title you would like to edit and click on Quick Edit

(Quick Edit fields)


Important: Modifying the category slug affects the URL of posts assigned to 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 category slug afterward if at all possible, especially after your site is established.

Categories – Useful Tip

In WordPress, every post must be assigned to a category. If you do not assign a post to a category, WordPress will assign your post automatically to the default category “Uncategorized” …

Post 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 users and better for search engines too.

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

Category Table: Uncategorized - Quick Edit

(Category: 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 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” in order to give your site an extra SEO boost …

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

(Change ‘Uncategorized’ category to something more meaningful to your site users 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 SEO-friendly URLs
