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 make finding information about similar topics on your site easier for visitors. Adding categories not only helps to organize your content, it also improves both your visitor’s experience and your search engine rankings.

Learn how to configure categories in WordPress posts in this tutorial.

Using WordPress Post Categories

Step 1: Configure Your Permalinks

Default WordPress post URLs 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 your WordPress site to display search engine 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 now before configuring your post categories.

If you need help with configuring permalinks, see this step-by-step tutorial: Improve Your WordPress SEO Using SEO-Friendly URLs

Step 2: List Your Topics

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

The first step, then, is to plan what kind of broad “topics” you will be publishing on your site. These can be topics related to your specific niche, your products or services, your industry, etc.

Important Info

If you need help planning a website, go here: A Comprehensive Guide To Website Planning 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 need to be better educated or informed about. This is very important in terms of establishing your web site as an “authority” that online visitors will want to come back again to learn from and/or refer other people to.

For example, let’s say 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 the following:

  • Marriage Celebrant FAQs
  • Marriage Celebrant Services
  • Wedding Planning
  • Marriage Vows
  • and so on …

Step 3: Select Relevant Category Topics

Dominating an entire market (i.e. “Weddings”, “Travel”, “Sports”, etc…) is extremely difficult, especially if you’re just getting started. It’s better to try and establish your authority in a niche, or segment of your main market.

Take a look at the illustration below …

How To Add, Edit And Delete WordPress Categories

You can see in the above 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 selecting 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 online searches performed each month for each of the sample keywords …

Use keyword research tools to help with category planning

(Use keyword research tools to help with category planning)

When planning your main topic categories, it’s important to spend time thinking carefully about all the elements you can control (like the main keywords used throughout your site), and how you are going to use these elements to try and gain a competitive advantage. If you set a goal that is too big (i.e. aiming 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 strategic online business planning like effective keyword research, identifying audience demographics, etc., see this tutorial: A Basic Guide To Web Site Planning 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 these keywords into WordPress post categories.

Step 4: Set Up WordPress Categories

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

Organize posts with categories

(WordPress lets you easily organize content using categories)

To access your WordPress Categories area, log into your WordPress dashboard, then go to your navigation menu and choose Posts > Categories

Posts - Categories

(Posts – Categories)

This opens the ‘Categories’ screen …

(Categories Section)

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

How To Add Categories

(WordPress Post Categories panel – Add New Category)

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

Categories screen - Add New Category fields

(WordPress Post Categories screen – Add New Category fields)

  1. Name – Use a short 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 then display in all category-related sections of your website.
  2. Slug – The “slug” are the words that display in the URL of all posts published under a specific 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 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. WordPress uses the category description you write here for the category pages “meta” description.

How To Delete WordPress Categories In Bulk

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


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

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

Useful Info

Important: Modifying the category slug affects the URL of posts published under that category. This can lead to “page not found” errors when visitors click on links pointing to posts published elsewhere.

For this reason, we 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.

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” …

WordPress category - 'Uncategorized'

(’Uncategorized’ WordPress post 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
