Whenever you make a new post on your WordPress blog, you have the opportunity to categorize it. Some people don’t bother, but SEO experts will tell you this is a big mistake.
To add a new category, you can do it from the actual blog post, by clicking Add Category, or you can click on your dashboard by navigating to Posts and then Categories, which takes you to the entire categories page so you can edit and manage all of your categories at once.
Here, you can create a new category and give it a parent category if you want this to work in a hierarchy system, with sub-categories. You’ll create the slug (which is the URL version of the category). Depending on the theme you’re using, you may want to add a description because some themes show the description while others don’t.
You can delete categories here too. If you delete a category, it doesn’t do away with your blog post. Instead, it just causes that blog post to return to the default category of “Uncategorized.”
Categories help your visitors navigate your website better. Some people truly depend on them to find what they need. Tags help too, but they’re a bit different. For instance, let’s say you have a vegetarian blog and one category is vegetarian foods.
You can post a blog post about a certain brand of food and place it in the vegetarian foods category. But the tags you use might be the brand name and type of food that it is, such as “Yvess, vegetarian corn dogs.”
The only bad thing about categories is if you over do it. If you have a long scrolling list of categories on your site, it can get confusing for your visitors. So it’s better to keep them trimmed back, and possibly create sub-categories instead.
