How To Add, Edit & Delete Post CategoriesWordPress post categories help make finding information on your site easier for visitors. Publishing posts under categories not only helps to keep your content organized, it also improves both your visitor’s experience and your search engine rankings.

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

Using WordPress Post Categories

Step 1: Configuring Permalinks

By default, post URLs in WordPress are not 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 look like this:

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

We have written a detailed tutorial about setting up and using permalinks here: How To Improve Your WordPress SEO With SEO-Friendly URLs

Step 2: Make A List Of Topics

Keeping 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 search engine results.

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

Useful Info

We have written a detailed tutorial about website planning here: Planning Your Business Web Site: A Basic Guide For Non-Technical Business Owners

When creating your list of topics, remember to 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 site as an online authority that visitors will want to come back repeatedly to and/or refer other people to.

For example, let’s say 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 the following:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Tips
  • Commitment Ceremonies
  • etc.

Step 3: Choose Relevant Category Names

Dominating an entire market (i.e. “Weddings”, “Travel”, “Business”, etc…) is extremely hard, especially if you’re just starting out. you have a better chance of getting somewhere by trying to build your authority in a niche, or a segment of your main market.

Take a look at the illustration below …

How To Add, Edit And Delete WordPress Categories

You can see from the above 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 Google’s estimates for the average number of monthly searches for each of the sample keywords …

Google Keyword Planner - Keyword research for category planning

(Google Keyword Planner – 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 have control over (like the keywords that will be used throughout your site), and how to use these elements to try and gain a competitive advantage. If you set an unrealistic goal (i.e. dominating the “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.

If you need help with strategic online business online strategies like keyword research, identifying audience demographics, etc., refer to this tutorial: The Website Planning Process: 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 convert your keywords into post categories.

Step 4: Set Up Your Categories

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

Organize your posts with categories

(WordPress allows you to easily organize content by categories)

To access your WordPress Categories section, log into your Dashboard and choose Posts > Categories

Posts - Categories

(Posts Menu – Categories)

This opens the ‘Categories’ panel …

Categories Panel

(Categories Section)

In this screen, you can create, edit, and remove categories, including inserting descriptions for categories and other information that can help to optimize your site for search engines.

How To Add Post Categories

(Categories screen – Add New Category area)

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

Post Categories panel - Add New Category fields

(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 site.
  2. Slug – The “slug” refers to the words that display in the URL of all posts published under a category. Your slug can be different than 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 hierarchies of categories 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 search engine optimization. Your category description will be used for the category pages “meta” description.

To learn how to create and edit WordPress posts, see the tutorials below:

Removing Categories


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

You can delete categories individually, or in bulk.

How To Delete Single Categories

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

Delete link

(Category table menu – Delete)

A window will pop up 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 Multiple Categories

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 you have too many categories to delete one at a time, this is where the bulk delete feature can be useful.


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

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

Next, go through the table and untick the box next to categories that you DO NOT want to delete. You can select/deselect categories by toggling on the check box next to the item.

Editing Categories In WordPress

To edit a post category, do the following:

(Edit link)

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

(Quick Edit fields)


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 that have already been indexed by search engines.

For this reason, we strongly recommend investing 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.

Post Category – Useful Tip

All posts must be assigned to categories in WordPress. If you do not assign a post to a category, WordPress will automatically assign your post to “Uncategorized” …

Category - 'Uncategorized'

(Category – ‘Uncategorized’)


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 readers and optimized for search engines too.

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

Category: Uncategorized - Quick Edit Link

(Category table menu: Uncategorized – Quick Edit)

Change the Category Name and Category Slug to a keyword or keyword phrase that will be 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 site readers and search engines

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

To optimize your site further, here are some more tips for getting the most benefit from using post categories.

Choose Keyword-Relevant Post Titles

In your content strategy, include the main keyword of your post in the post title, preferably at the beginning. This helps to optimize your page for search engines, and improves click-through rates.

So, for example, an article on Outdoors Adventure Travel focused on the “Winter Camping” niche could be titled “Winter Camping Tips – 5 Survival Accessories Everyone Needs For A Safe Winter Camping Trip“.
