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.

Add, Edit, And Delete CategoriesWordPress post categories can help to make finding information on your site easier for visitors. Categories also help to organize your content and allow search engines to better index your WordPress site.

This step-by-step tutorial helps you learn how to configure and use post categories.

Step 1: Configure Your Permalinks

Out of the box, WordPress post URLs aren’t 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 post link that looks like this:

The post URL can look like this:

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

We have written a detailed tutorial on setting up permalinks here: How To Improve Your WordPress SEO Using SEO-Friendly URLs

Step 2: Create A List Of Topics

Keeping your 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 boost your site’s optimization for better SEO.

The first step, then, is to work out what kind of broad “topics” you will write about. These can be topics related to your specific niche, your products or services, and even your industry.


If you need help website planning, go here: A Comprehensive Guide To Website Planning For Business Owners

When creating your list of topics, include areas of your business that your visitors, prospects, and clients should be better educated or informed about. This is 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.

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

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

Step 3: Choose Relevant Category Titles

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Business”, etc…) is very hard to do, especially when you’re just getting started. you have a better chance of getting somewhere by trying to establish your authority in a niche, or sub niche of your 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 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 publish 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 online searches performed each month for each of the above keywords …

Keyword research can help you with category planning

(Keyword research can help you with category planning)

When planning category topics, it’s important to take your time and think carefully about all the elements you can control (like the keywords that will be used throughout your site), and how you are going to use these elements to try and gain a competitive advantage. If you set an unrealistic 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 narrow niche or microniche, you could experience little to no activity on your site and hence no significant opportunities to increase your business online.

If you need help with strategic online business planning like keyword research, identifying audience demographics, etc., see this tutorial: A Cost-Saving Guide To Web Site Planning 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 convert these into post categories.

Step 4: Set Up Post Categories

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

Organize your content using categories

(WordPress allows you to easily organize content with categories)

To access your WordPress Categories section, in your Dashboard menu section, click on Posts > Categories

To add a new category to WordPress, simply fill in the fields in the ‘Add New Category’ area as shown in the example below:

(WordPress Post Categories panel – Add New Category fields)

  1. Name – Type a short 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” refers to the words that display in the URL of all posts published under a specific category. The 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 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 website.
  4. Description – Add a brief category description 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 bulk delete categories, click on the main checkbox in the header row. This will select all category listings on the page.

Useful Information

Important: Changing the category slug affects the URL of all 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 category slug afterward if at all possible, especially after your posts and pages have already been indexed in the search engines.

WordPress Category – Useful 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 automatically to a default category called “Uncategorized” …

'Uncategorized' WordPress post category

(’Uncategorized’ category)

Useful Info

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 site visitors and optimize it better for search engines too.

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

Category: Uncategorized - Quick Edit Link

(Quick Edit link)

Change both 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 …
