Learn how to add a category in WordPress websites thereby improving the experience of visitors to your site.

Gaining a good understanding of the correct procedure for Categories in WordPress before publishing to a new website, is something to take notice of.

Being knowledgeable about Categories in WordPress was not at the top of my list when building my first website. In my early days of experiencing internet marketing I mainly learned by trial and error. Sometimes error being more predominant than success.

So, that does not need to happen to you as I will show you just how simple it is to manage categories in WordPress.

The first thing to deal with is:

Exactly What a Category Is in WordPress

The Merriam Webster Thesaurus states: – A Category is a division within a system of classification.

In WordPress, it is simple to appropriately name ‘divisions’ and provide for easy navigation throughout a website.

Please note that ‘Divisions’, as referred to by the Merriam Webster Dictionary, are known in WordPress as ‘Parent Categories’ and ‘Child Categories’.

About Parent Categories

To keep things simple, I relate Parent Categories to a book. Let’s say you are interested in finding information about different brands of motor vehicles.

You see a book for sale named “Best Motor Vehicles” You decide to purchase the book because it has information about several brands of motor vehicles, and you feel you just have to buy this book.

So, relating this to a website, the title of the book “Best Motor Vehicles” would be the Parent Category

About Child Categories

Again, think about the Chapters in the book. Each Chapter has its own title, such as:

  • Jaguar
  • Bently
  • Holden
  • Toyota
  • Suzuki
  • Honda
  • Daewoo.

Relate these to a website about motor vehicles, and they are the Child Categories.

Why Categories Need to be Included in Your Website

There are two main reasons why Categories need to be included in your website.

1. To Help Visitors Find Information They Are Looking For   

An example is: You visit a dog training website to find information about how to stop your dog from biting.

The most prominent information to be found is about what to feed a dog, or how walk a dog, and many other dog related issues, but no information about how to stop a dog from biting.

It’s not long before you leave that website and look for a website that provides clear information, easily found. And, the reason information is clearly accessible on the second site you visit is because of well-organized categories.

2. For Search Engine Optimization   

Categories also assist with Search Engine Optimization (SEO). In turn, SEO assists with the ranking of your website.

So, you can see from this the importance of giving attention to the Categories in your WordPress website.


Where On Your Website You Can Access Categories

WordPress provides 2 areas where you can enter category information.

The First and most accessible area is from in the WordPress Dashboard

Access your website Dashboard and on the left-hand side of your screen click on Posts –> Categories as shown in the image below.

How to use Categories in WordPress

This opens to a new area where you will:

  • Name the Category
  • Add the slug
  • Select Parent Category (The Parent category is always the Name of the category. See image below)

Note that I have not placed an arrow in the Description as it is not necessary to include a description. However, as you build your site you may wish to add a description of each category. It is your choice.

Please read the information below this image about Parent and Child Categories

Adding a new category








Parent Categories

The image directly above shows where to place the Name and Slug of a new Parent Category.

When adding the slug, insert a dash between each word. e.g. food-for-adult-dogs

Note that where the 3rd Red Arrow is you can see a Down Arrow. This Down Arrow needs to be ignored when creating a Parent Category.


Child Categories

  • Type the name of the Child Category (See image below – Food Not To Eat)
  • Then enter the slug (food-not-to-eat)
  • Now select the Parent Category (Canine Diet)

When creating Child Categories, the down arrow shown in the image below, is clicked and a Parent Category selected.

Name of child category








The next image shows that Parent Categories of ‘Canine Diet’ and ‘Dog Behavior Training’ are now in place. Beneath each of these two categories, Child Categories have been added.

Managing categories in WordPress









The Second Area to Access Categories is on the Right-hand side of the WordPress Dashboard.

To access this area, first make sure that Categories are enabled at the top of the WordPress Dashboard. This is done by clicking on Screen Options (near the top left-hand side) and checking off Categories (see image).

Selecting Categories on a WordPress website







As seen in the image below, this is a second option for managing Categories in a WordPress website.

Categories and Pages Do Not Go Together

It is important to note that Categories in WordPress do not apply to Pages. Working with Pages is a different hierarchy managed in WordPress Menus.

How Many Categories Should be Included in a Website

There are varying opinions regarding the number of categories to include in a website, and that is something you will find depends on your site.

The important thing is to aim for a tidy and well-structured list of categories.

Child categories will be much greater in number than Parent categories.

As shown in the third image above, the two Parent categories each have multiple Child categories. Remember that the image is an example. In most cases, a functional website would have many more Child Categories listed beneath Parent Categories.

About ‘Uncategorized’ Categories

Avoid the use of an Uncategorized category. This will not benefit your website in any way at all.

In the event of being undecided on a suitable category for a post, place it as a Child Category under a Parent Category that has the closest relevancy to your new post. By categorizing the post it will add to user experience as well as have SEO value, which is not the case with Uncategorized posts.

Can a Post be Placed in More Than One Category

It is said that a post can have more than one category. However, it is also said that a post should be in one category only.

As mentioned at the beginning of this post, I had little knowledge when starting out with WordPress. However, over the years I have studied and practised building websites for affiliate marketing.

Now, from experience, I recommend placing each post on your website in one category only.

Where to Display Categories On Your Website

The most popular way to provide visitors with easy access to Categories on your site is to display them in a Sidebar. To do this you will need to use a widget that can be accessed from the WordPress Dashboard.

On the left-hand side of the Dashboard, click on Appearance then click on Widgets

Look for Available Widgets — Categories (as shown below)

How to Use a Widget for Displaying Categories






Left click on Categories and slide the tab to the right-hand side for placement on the Sidebar.

How to Slide a Category Tab into a Sidebar










To choose how to display the categories, Click on the Down Arrow in the Category tab where you will see 3 options. I suggest you try each option and view their appearance on your website.

My Final Recommendation about How to Add a Category in WordPress

I am including a video that I recommend you watch. Although this video is on the lengthy side, I believe it is well worth your time to watch, listen and make notes.

The correct use of Categories is essential to the success of your website.

From watching the video you will also learn a little about Tags. I have not mentioned tags in this post due to the fact that I don’t believe they hold great importance these days. Also, I did not wish to complicate the use of Tags, as opposed to Categories, for anyone new to WordPress.

It is common knowledge that points of view about the way to manage WordPress websites varies between those who build websites. Again, you will make your own decisions as your confidence with building a website grows. The more knowledge you gain from authorities in particular areas, the greater understanding you will have of how to develop and maintain your own website.

So here the video for you to enjoy.


I would be interested in reading your comments about what you gained from the video.
