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 Post Categories In WordPressWordPress categories help to make finding information about similar topics on your site easier for visitors. Publishing posts under categories also helps to keep you content organized and allows search engines to better index your WordPress site.

In this tutorial, you will learn about adding, editing & deleting categories in WP posts.

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 post categories, you will 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:

You can have the post URL display like this:

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

If you need help with setting up and using permalinks, refer to this step-by-step tutorial: How To Improve Your WordPress SEO Using Permalinks

Step 2: List Your Topics

Keeping 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 search engines to better index your content.

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


We have written a detailed tutorial on website planning here: The Web Site Planning Process Explained - A Useful Guide For Business Owners

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

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

Step 3: Choose Relevant Category Titles

Dominating an entire market (i.e. “Weddings”, “Travel”, “Business”, 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 a segment of your main market.

Take a look at the example below …

How To Add, Edit And Delete WordPress Categories

You can see from 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 larger “Weddings” market (another category).

When deciding on 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 estimates from Google for the average number of online searches performed each month for each of these keywords …

Keyword research can help you with category planning

(Keyword research - a useful tool for category planning)

When planning category topics, it’s important to spend time thinking 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 to a competitive advantage. If you set an unrealistic 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 market share online.

If you need help with strategic online business online strategies like effective keyword research, identifying target audience demographics, etc., refer to this tutorial: Planning Your Business Website: A Useful Primer For Business Owners

After mapping out your top-level topics and figuring out what your main keywords are, the next step is to turn these keywords into post categories.

Step 4: Set Up Your WP Post Categories

Publishing your WordPress posts under categories that best 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 content for search engines.

(Post Categories screen – Add New Category section 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 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 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 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 your category pages “meta” description.

Useful Information

Changing the category slug will affect the URL of all posts published under 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.

Post Category – Special Tip

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

'Uncategorized' category

(Category – ‘Uncategorized’)

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)

Category Table Menu: Uncategorized - Quick Edit Link

(Category table: Uncategorized – Quick Edit)

Change both the Category Name and Category Slug to a keyword or keyword phrase that will be relevant to the main topic of your site.
