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.

Using Categories In WordPressWordPress post categories 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.

Learn about configuring and using WordPress categories in this step-by-step tutorial.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post URLs are not search engine friendly. In order to make the best use of WordPress categories, you will 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 do so first before configuring your post categories.

For more information about setting up permalinks, go here: Improve Your WordPress SEO With Permalinks

Step 2: Make A List Of Topics

Maintaining your 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 search engines to better index your content.

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


We have written a detailed tutorial about website planning here: A Practical Guide To Website 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 need to be better educated or informed about. This is very important in terms of establishing your website as an online authority that visitors will want to come back repeatedly to and/or refer to others.

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:

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

Step 3: Choose Relevant Category Titles

Dominating an entire market (i.e. “Weddings”, “Travel”, “Sports”, etc…) is very difficult, especially when you’re just starting out. you have a better chance of getting somewhere by trying to establish your authority in a smaller niche, or segment (i.e. subniche) 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 Market > Niche > Subniche 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 “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 the above keywords …

Use keyword research tools to help plan your categories

(Use keyword research to help plan your categories)

When planning category topics, it’s important to spend time thinking carefully about all the elements you can control (like the main keywords used throughout your content), and how to use these elements to try and gain a competitive advantage. If you set a goal that is too big (i.e. dominating 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 sub-niche, you could experience little to no activity on your site and hence no significant opportunities to grow your business online.

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

Step 4: Set Up Categories

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

Organize your content with categories

(Organize content using categories)

To access your Categories area, log into the WordPress administration section and choose Posts > Categories

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

WP Post Categories screen - Add New Category section fields

(WP Post Categories panel – Add New Category section 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 then display in all the category-related sections of your site.
  2. Slug – The “slug” are the words that display in the URL of all posts published under a specific category. Your slug can be different from 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 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 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 your category pages “meta” description.

How To Delete Multiple WordPress Categories

Let’s say that you import product data into your WordPress site containing a large number of categories (e.g. product manufacturers), and you want to consolidate posts to a single category. If you have too many categories to delete one at a time, this is where the bulk delete feature comes in handy.


Important: Make sure that any posts that will be affected when unwanted categories are deleted have been reassigned to an existing or new category. For more details on how to reassign categories in posts, go to this tutorial: How To Edit And Delete WordPress Posts

To delete multiple WordPress categories, click on the main checkbox next to the ‘Name’ column title. This will select all items .

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

How To Edit Post Categories

To edit a WordPress post category, do the following:

In your ‘Categories’ panel, locate the category item that you would like to edit, then place your mouse over the category title, and click Edit

Edit link - WordPress category table

(WordPress post category – Edit link)

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

(‘Edit Category’ screen)

You can also edit a category using the Quick Edit option. Hover over the category title you want to edit and click on Quick Edit

Quick Edit link

(Quick Edit link – Category table)

Edit your details and click Update Category to save your changes …

(Quick Edit fields)


Modifying the category slug changes 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 post category slug afterward if at all possible, especially after your posts and pages have been indexed in the search engines.

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 attribute your post automatically to the default category “Uncategorized” …

'Uncategorized' WordPress category

(’Uncategorized’ post category)

Useful Information

The default category cannot be deleted.

Having posts attributed to 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 unassigned posts as “uncategorized”, let’s make the category a little more relevant to your site users and optimized for search engines too.

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

Quick Edit

(Category table: Uncategorized – Quick Edit)

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

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

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

Use SEO-friendly URLs

Note: The site used in the example above has been configured to display search engine-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, go here: Improve Your WordPress SEO With Permalinks

Step 5 – Using Categories Effectively

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

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

Choosing Relevant Keywords For Post Titles

When creating content for your site, always try to include the main keyword of your post in the title of your post, preferably at the beginning. This helps to optimize your page for search engines, and improves click through rates.

So, for example, if writing a blog post on Outdoors Adventure Travel focused on the “Winter Camping” niche could be titled “Winter Camping Tips – 7 Essential Survival Tools Everyone Needs For A Safe Winter Camping Trip“.

Publish Posts Under Relevant Post Categories

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