Using WordPress Post Categories

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

In this tutorial, you will learn how to set up post categories in WordPress.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

By default, WordPress URLs aren’t really search engine friendly. In order to make the best use of WordPress 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:


The same post URL can display like this:


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

We have written a detailed tutorial about permalinks here: Changing Your WordPress Permalinks

Step 2: List Your Topics

Maintaining 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 searching for, but can also help to boost your site’s optimization for improved search results.

The first step, therefore, is to carefully plan what kind of broad “topics” you will be writing about. These can be topics related to your niche, your products or services, and even your industry.

If you need help with website planning, see this tutorial: A Cost-Saving Guide To Web Site Planning For Non-Technical Business Owners

When creating your list of topics, 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 website as an “authority” that online 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:

Step 3: Select Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is extremely difficult, especially if you’re just starting out. It’s better to focus on building your authority in a smaller niche, or segment of your market.

Take a look at the illustration below …

You can see from the above Market > Niche > Sub niche 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 choosing 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 Google’s estimates for the average number of monthly searches for each of the above keywords …

(Google Keyword Planner – Useful keyword research tool for category planning)

When planning your main topic categories, it’s important to take your time and think carefully about all the elements you can control (like the main keywords 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. trying to dominate the entire “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.

For tutorials on online business online strategies like effective keyword research, identifying audience demographics, etc., see this tutorial: The Web Site Planning Process: A Practical 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 post categories.

Step 4: Set Up Your Post Categories

Saving WordPress posts under carefully planned categories that relate to the main topics of your site helps keep your content organized, provides online 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)

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

(Posts – Categories)

This brings you to the ‘Categories’ screen …

(Post Categories Screen)

In this panel, you can create, edit, and delete categories, including inserting descriptions for categories and other information that can improve your website’s SEO.

How To Add WordPress Categories

(Categories screen – Add New Category)

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

(Post Categories screen – Add New Category fields)

  1. Name – Type 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 specific category. Your 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 your category name.
  3. Parent – Ignore this field, unless you plan to create nested hierarchies of categories on your website.
  4. Description – Write 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 Add New Category to add your new category …

How To Remove Post Categories

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

You can delete categories individually, or in bulk.

Deleting Single Categories

To delete categories individually, place your mouse over the category you would like removed and a menu will display containing a range of options. Click Delete to remove the category from your list …

(How to delete an individual category)

A window will appear asking you to confirm the deletion. Click OK to proceed, or Cancel to abort …

(Click ‘OK’ to proceed)

Deleting Categories In Bulk

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 fewer number of categories. If you have too many categories to delete individually, this is where the bulk delete feature can be useful.

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 how to reassign categories in posts, see this tutorial: Editing And Deleting A Post In WordPress

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

Next, go through the table and unselect any 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)

After ticking all the entries you would like to delete, select the ‘Delete’ option from the ‘Bulk Actions’ pulldown menu …

(Choose ‘Delete’ from the ‘Bulk Actions’ dropdown menu)

With the ‘Delete’ option selected in the drop down menu, click the ‘Apply’ button …

(Deleting multiple categories)

The categories you’ve selected will be deleted …

(Categories deleted)

How To Edit Categories

To edit a category, do this:

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

(WordPress category table – Edit)

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

(‘Edit Category’ screen)

You can also edit a category using the Quick Edit option. Hover over the category title you would like to edit and click the ‘Quick Edit’ link …

(Quick Edit)

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

(Category table menu – Quick Edit fields)

Important: Modifying the category slug affects the URL of posts assigned for 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 Categories – Special 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’)

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)

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 the ‘Quick Edit’ link …

(Category table menu: 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 an extra SEO boost …

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

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

(SEO improved URLs)

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

Step 5 – Use WordPress Categories Effectively

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

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

Choosing Relevant Keywords For Your Post Titles

As you create new content for your site, include the main keyword of your post in the title, preferably near the beginning. This helps to optimize your post for search engines, and improves clickthrough rates.

So, for example, an article on Outdoors Adventure Travel focused on the ”Kayaking” niche could be titled “Kayaking In Australia – 7 Remote Kayaking Destinations“.

Publish Posts Under Relevant Post Categories

Every time you add a new article or post, remember to select the correct category box before publishing your post …
