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 …

How To Configure Categories In WordPress PostsWordPress categories help to make finding information about similar topics on your site easier for visitors. Adding categories not only helps to keep your content organized, it also improves both your visitor’s search experience and your search engine rankings.

In this step-by-step tutorial, you will learn about adding, editing, and deleting categories in posts.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Out of the box, post URLs in WordPress aren’t 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 search engine friendly URLs, so instead of having a web address that looks like this:

You can have the post URL display like this:

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

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 searching for, but can also help search engines to better index your content.

The first step, then, is to carefully plan what kind of broad “topics” you will write about and publish on your site. These can be topics related to your specific niche, your business, your industry, etc.

Important Info

When creating your list of topics, remember to 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 online authority that visitors will want to subscribe to (if you offer a newsletter or ongoing training, tips, etc.) and/or refer other people to.

For example, let’s say that you want 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 Locations
  • Marriage Vows
  • and so on …

Step 3: Select Relevant Category Headings

Dominating an entire market (i.e. “Weddings”, “Travel”, “Pets”, etc…) is very difficult, especially if you’re just starting out. you have a better chance of getting somewhere by focusing on building your authority in a smaller niche, or a micro niche 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 estimates from Google for the average number of monthly searches for each of these keywords …

Use keyword research to help plan your categories

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

When planning your topic categories, it’s important to take your time and think carefully about all the elements you have control over (like the main keywords used throughout your site), and how to use these elements to gain a competitive advantage. If you set a goal that is too big (i.e. dominating 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 grow your market share online.

If you need help with strategic online business areas like effective keyword research, identifying audience demographics, etc., see this tutorial: How To Plan Your Business Website - A Useful Guide 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 Categories

Publishing your 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 content using categories

(Organize posts by categories)

To access your WordPress Post Categories area, log into the Dashboard and choose Posts > Categories

(Categories panel – 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 then 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. The slug can be different from 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 create one for you using a lower case version of the category name.
  3. Parent – Ignore this field, unless you plan to create nested category hierarchies on your website (explained further below).
  4. Description – Write a brief category description 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.

How To Delete Categories In Bulk

Let’s say that you import product data into your WordPress site containing a large number of categories (e.g. an e-commerce catalog), and you would like to consolidate posts to a single category. If you have too many categories to delete individually, this is where the bulk delete feature can be useful.

Important Info

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, go to this tutorial: Editing And Deleting A Post

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

Important: Changing the category slug will affect the URL of all posts assigned to that category. This can lead to “page not found” errors when visitors click on links to posts published elsewhere.

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 already been indexed in the search engines.

Post Category – Useful Tip

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

'Uncategorized' post category

(Post category – ‘Uncategorized’)


The default category cannot be deleted.

Assigning posts 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 posts as “uncategorized”, let’s make the category a little more relevant to your site visitors and better for search engines too.

Place your mouse over the “Uncategorized” entry and click on Quick Edit

Quick Edit

(Quick Edit)

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” to give your site an extra SEO boost …

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

SEO experts recommend including the main keyword of your post in your the title, preferably near the beginning. This helps to optimize your page for search engines, and improves clickthrough rates.

So, for example, if writing a blog post for an Outdoors Adventure Travel company focused on the ”Kayaking” niche could be titled “Kayaking In Australia – The 3 Most Insane Kayaking Destinations“.
