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 And Use Categories In WP PostsWordPress post categories help to make finding information about similar topics 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 search experience and your search engine rankings.

This step-by-step tutorial helps you learn about configuring and using categories in WP posts.

Using WordPress Post Categories

Step 1: Configuring Permalinks

Default WordPress post web addresses aren’t really search engine friendly. In order to make the best use of post categories, you will need to modify the way WordPress displays your URLs.

Permalinks allow WordPress to display SEO-friendly URLs, so instead of having a post link 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 categories.

To learn more about permalinks, see this tutorial: How To Improve Your WordPress SEO Using SEO-Friendly URLs

Step 2: Make A List Of Your Main Topics

Maintaining your content organized is very 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 boost your site’s optimization for better search engine results.

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

Important Info

To learn more about planning a website, see this step-by-step tutorial: Planning Your Web Site: A Useful 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 website as an online authority that visitors will want to subscribe to (if you offer a newsletter or valuable content like ongoing training, tips, etc.) and/or refer to others.

Let’s say, for example, 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 Tips
  • Marriage Vows
  • and so on …

Step 3: Select Relevant Category Names

Dominating a vertical market (i.e. “Weddings”, “Travel”, “Health”, etc…) is extremely hard, especially when you’re just getting started. you have a better chance of getting somewhere by trying to build your authority in a niche, or micro 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 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 selecting 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 the above keywords …

Google Keyword Planner - Useful keyword research for category planning

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

When planning category titles, 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 to use these elements to try to a competitive advantage. If you set too big a 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 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 online strategies like keyword research, identifying audience demographics, etc., refer to this tutorial: The Website Planning Process - A Cost-Saving Blueprint For Non-Technical Business Owners

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

Step 4: Set Up Categories

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

(WordPress Post Categories panel – Add New Category section fields)

  1. Name – Enter 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 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 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 automatically using a lower case version of the category name.
  3. Parent – Ignore this field, unless you plan to create nested category hierarchies on your site.
  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 your category pages “meta” description.

How To Delete Post Categories In WordPress


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

You can delete categories individually, or in bulk.

To remove an individual category, hover over the category you would like to delete and click Delete

Deleting a single category

(Delete link)

A message will pop up in your browser asking you to confirm the deletion. Click OK to permanently delete the item, or Cancel to stop …

Deleting Categories In Bulk

Let’s say that you import product data into your 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 individually, this is where the bulk delete feature comes in handy.


Important: Make sure that any posts that may be affected by deleting unwanted categories have been reassigned to an existing or new category. For more details on how to reassign categories in posts, go to this tutorial: Editing And Deleting A Post

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

Important: Changing the category slug will affect the URL of posts assigned for 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, it’s best to invest 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.

WordPress Categories – Special 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 “Uncategorized” …

Category - 'Uncategorized'

(Category – ‘Uncategorized’)

Important Info

Having posts assigned to 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)

Step 5 – Using WordPress Post Categories Effectively

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

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

Choosing Relevant Keywords For Your Post Titles

As you create new content for your site, include the main keyword of your post in your post title, preferably near the beginning. This helps to optimize your post for search engines, and improves click through rates.

So, for example, an article for an Outdoors Adventure Travel site focused on the ”Kayaking” niche could be titled “Kayaking Adventures – 7 Insane Kayaking Adventures“.

Publish Your WordPress Posts Under The Correct Category
