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 categories help to make finding information about similar topics on your site easier for visitors. Categories also help to organize your content and allow search engines to better index your WordPress site.

Learn about configuring & using WordPress categories in this step-by-step tutorial.

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 let you display SEO-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 we recommend doing so now before configuring your post categories.

If you need help with permalinks, refer to this tutorial: Setting Up Your WordPress Permalinks

Step 2: Make A List Of Topics

Maintaining your site’s 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 significantly boost your site’s optimization for improved SEO.

We recommend, therefore, first planning what kind of broad “topics” you will write about and publish on your site. These can be topics related to your specific niche, your products or services, and even your industry.

Important Info

We have written a detailed tutorial about planning a website here: A Practical Guide To Web Site Planning For Business Owners

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 web site as an online authority that visitors will want to come back again to learn from 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 Locations
  • Commitment Ceremonies
  • etc.

Step 3: Select Relevant Category Headings

Dominating an entire market (i.e. “Weddings”, “Travel”, “Sports”, etc…) is extremely hard, especially if you’re just getting started. It’s better to focus on establishing your authority in a smaller niche, or a subniche 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 subniche (i.e. a subcategory) of the “Marriage Celebrant” niche (a category), which itself is a subcategory of the “Weddings” market (another category).

When deciding on 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 monthly searches for each of the sample keywords …

Google Keyword Planner - Keyword research tool for category planning

(Use keyword research to help plan your categories)

When planning your 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 you are going to use these elements to try and gain a competitive advantage. If you set a strategic objective 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 increase your market share online.

For tutorials on strategic online business planning like keyword research, identifying audience demographics, etc., see this tutorial: How To Plan Your Business Website: A Money-Saving Guide For Business Owners

After mapping out your top-level topics and figuring out what your main keywords are, the next step is to convert these into categories and add them to your WordPress website or blog.

Step 4: Set Up Post Categories

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

Organize content with categories

(WordPress allows you to easily organize your posts using categories)

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

WordPress Posts Menu - Categories

(Posts – Categories)

This opens the ‘Categories’ panel …

(WordPress Post Categories Section)

This screen lets you add, edit, and remove categories, including inserting category descriptions and other information that can help to optimize your site for search engines.

How To Add WordPress Post Categories

(Post Categories screen – Add New Category area)

To create a new post category, simply fill in the fields in the ‘Add New Category’ section as per the example below:

Categories panel - Add New Category area fields

(Categories screen – Add New Category fields)

  1. Name – Enter 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 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 than 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.
  4. Description – Write 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.

Deleting Categories In WordPress

Useful Information

Deleting a category does not delete posts assigned to that category. Instead, any posts that were assigned to the deleted category will be reassigned to the WordPress default category (see further below).

You can delete categories individually, or in bulk.

Deleting Categories Individually

To remove a single category, place your mouse over the category and click Delete

WordPress category - Delete

(How to delete categories individually)

A warning message will appear in your browser asking you to confirm the deletion. Click OK to go ahead, or Cancel to abort …

Click 'OK' to delete the category

(Click ‘OK’ to delete the category)

Deleting Multiple Categories

Let’s say that you import product data into your WordPress site containing a large number of categories (e.g. product manufacturers), and you want to consolidate posts to a fewer number of categories. 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 will be affected when unwanted categories are removed have been reassigned to an existing or new category. For more details on how to reassign post categories, refer to this tutorial: Editing And Deleting Posts

To delete multiple WordPress categories, click on the main check box next to the ‘Name’ column title. This will select all category items on the page.

Next, go through the table and deselect any categories that you DO NOT want to delete. You can select/deselect categories by toggling on the checkbox next to the item.

(Quick Edit)

(Category table menu – Quick Edit screen)

Important Info

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

WordPress Post 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 automatically assign your post to “Uncategorized” …

'Uncategorized' category

(’Uncategorized’ WordPress post category)


The default category cannot be deleted.

Having posts attributed 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)

Instead of publishing unassigned posts as “uncategorized”, let’s make the category a little more relevant to your readers and optimized for search engines too.

Hover over the “Uncategorized” entry and click on the ‘Quick Edit’ link …

Category: Uncategorized - Quick Edit Link

(Category: 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. 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 …

Change 'Uncategorized' category to something more meaningful to your readers and search engines

(Change ‘Uncategorized’ category to something more meaningful to your users and search engines)

Now, when posts are published under the default WordPress category, the URL will make more sense to visitors and be more effective for SEO …

Use SEO-friendly URLs

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

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

Choose Relevant Keywords For Your Post Titles

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

So, for example, a blog post on Outdoors Adventure Travel targeting the “Winter Camping” niche could be titled “Winter Camping Tips – 5 Survival Accessories Everyone Needs For A Safe Winter Camping Adventure“.
