How To Make Categorising And Tagging Blog Posts Powerful

Categorising and tagging blog posts are some of the most potent ways for bloggers to get their posts noticed. However, some bloggers don’t bother with either, meaning they’re losing the potential for new readers and followers. Are you one of them?

But what are categories and tags, and how do they work?

Do you categorise and add tags to all your blog posts?

What are blogging categories?

Blogging categories act like groups where blog posts that have a connection with each other are stored.

For example, if you’re a travel blogger, you could have The United Kingdom category and list the sub-categories Scotland, Wales, England, and Northern Ireland

Categories are important because they make finding specific blog posts more straightforward for visitors to your blog (especially first-time visitors).

Every blog post should have at least one category.

Unfortunately, if you don’t categorise blog posts, they will be uncategorised, which is no help to anyone.

Imagine going into a shop to find a particular book about dinosaurs and finding that none of the books has been categorised. You’d leave and go to another shop that helps customers by categorising its books to find what you’re looking for much easier.

I never return to blogs that do not categorise posts.

How to add a category to your WordPress blog post

This tutorial uses an Apple iMac desktop computer and the WordPress ‘Default’ dashboard.

  • While drafting a blog post, you’ll see a toolbar in the settings area on the right-hand side of the page. This is where you can add categories.

Every blog post should have at least one category.

If a blog post doesn’t fit into one of your existing categories, click ‘Add New Category‘ and create a new one.

Remember to do some housekeeping regularly for the categories on your blog. For example, delete categories that are no longer being used or update categories by giving them a new name if something works better. 

How to edit the categories on your blog.

  • On your blog’s dashboard, click on Posts to open a submenu, and click on Categories.

Click Posts and Categories.
  • To edit a category, click the three verticle dots (meatball menu) next to the category you want to edit.

Click the meatball menu to edit a category.
  • The meatball menu displays four options: edit, delete, view posts, and set as a default.
  • Edit – Edit the name or description of the category.
  • Delete – Delete the category.
  • View posts – View a list of all your posts under the category.
  • Set as default – Useful when most posts fall under a particular category.
  • Remember to click the ‘Update‘ button to save any changes you make.

The number next to each category tells you how many posts are under that category. I recommend deleting any categories that are not being used.

Any sub-categories will show under each category.   

Tip: Setting your default category to ‘Uncatorigised‘ allows you to search for any blog posts you may have forgotten to categorise.

What are tags?

Tags are popular keywords that can be added to a blog post. For example, some of the tag words I’ve added to this post are –

  • blogging
  • bloggingtips
  • categories
  • tags
  • WordPress
  • HowTo

Each tag should be separated with a comma or by pushing ‘Enter’ on your keyboard.

Tags containing more than one word (such as ‘Blogging tips’) act as one tag word, but you must add them without any space between the words, i.e., ‘ blogging tips’ becomes ‘bloggingtips.’

Generally, tags do not need to connect with each other, but when used correctly, they can generate a lot of extra traffic to a blog post.

Like categories, tags can be added to blog posts in the settings area toolbar on the right side of a draft post.

Always add keywords (Tags) to your blog posts.

When adding tags to your post, consider the keywords somebody would add to the WordPress search bar when looking for specific blog posts. Or think of words you would use to search for your post.

Check out the tags I’ve added for this blog post. They appear at the end of every post.  

Important information – Did you know this…?

The cardinal tagging rule on WordPress.com is that you should never add more than 15 tags and categories (combined) to your post; otherwise, it won’t appear in the WordPress Reader. This cap prevents spam posts from appearing on the reader list, as spammers and spambots tend to use many categories and tags to lure readers in

15 tags and categories can seem like a lot, but you don’t need to use all of them.

Never tag your blog post with words that have nothing to do with the post’s subject. Otherwise, visitors will come to your blog under false pretences and probably won’t return.

Generally, I add no more than three categories and between six and ten tags to my blog posts. 

As with categories, it’s also essential to do some housekeeping for the tags you use on your blog. 

How to delete and update tags

  • On the dashboard of your blog, click on Posts – Tags.
  • A page showing your tags and how many blog posts containing each tag appears.
  • To edit, view and delete posts containing a tag word, hover your mouse over each tag word and click edit, quick edit, view or delete.
  • You can also view the posts containing the tag word by clicking the number in the ‘Count’ column. I recommend deleting any tag words that are no longer being used.

Let’s wrap it up!

  • All blog posts should be categorised and tagged.
  • Categorising and tagging your blog posts makes them user-friendly, meaning people will likely return to your blog.
  • Not categorising your blog posts means they’ll be challenging to find.
  • When tagging posts, think of keywords others will use when searching for your blog post.
  • Don’t use tag words that have nothing to do with the subject of your blog post.
  • WordPress users – never add more than 15 tags and categories (combined) to your posts; otherwise, they won’t appear on the WordPress Reader.
  • Remember to perform regular housekeeping of categories and tags on your blog.
  • Adding the proper tags to your blog posts will increase the number of readers who find them. More readers mean higher stats, more comments, and new followers.

  1. I almost missed this important post, Hugh! Guess I was busy last week, LOL! Thanks for the reminder to adjust my tags. What I like about this post is that you tell us two important concept: appropriate categories and tags used to bring readers to our posts. Using too many tags is counterproductive, so I keep mine at that number or under. I rarely use more than 3 categories. Apparently my default category is leisure, then I add the appropriate categories with each post.

    Today is a good day to update both! Thanks again for all of your great blogging tips!

    1. I’m glad this post has helped, Terri. I saw it as an opportunity to remind many bloggers to housekeep their tags and categories and not to overdo them when tagging and categorising posts. Some bloggers blame WordPress when their posts do not appear on the reader, yet if they only stopped using so many tags and categories, they’d solve the problem.

    1. It wasn’t until I took a WordPress course that I learned the importance of categorising and tagging blog posts, Linda. Fortunately, I took the course a month after creating my blog.

  2. Thanks for the info, Hugh! I use categories and tags all the time, but I wasn’t aware of the maximum 15 rule. Good to know. Shared as well. :)

  3. This is very helpful, Hugh. I use tags and categories but I’ve always been unsure I am using the proper tags. Your post is very beneficial to me in the use of tags and thank you.

  4. Super helpful! I like how you explained this in an easy to understand straight forward way. Very useful for someone trying to create categories thanks a lot for sharing!

    1. Thank you for the great feedback on how easy the tutorial in the post was to follow, Andrea. I’m not keen on too much jargon, so your comment is helpful for future posts.

  5. Yes, I do categorize and tag all my posts. I didn’t know about the 15 maximum, although I’d be very surprised if any of mine had more than that. You’ve reminded me that I should be reviewing my tags when I refresh old posts. That’s something I never think to do.

    1. It’s definitely worth reviewing the tags and categories in older posts. I always treat old posts as brand new, so I review the excerpt of the post, too. Good to hear you’re already tagging and categorising posts.

  6. Super informative and insightful post, Hugh. Especially since I thought I knew all about categories and tags, but I did learn something new – like not adding more than 15 words combined (I always seem to do more, as in anything I can think about that fits my posts) and not adding a space in between two words that I use as a tag!

    So, if we delete tags or categories that are not used anymore, would they get deleted from older posts where we did use those specific terms?

    1. Spammers and spambots always add more than 15 tags and categories to lure in as many readers as possible, Liesbet. So it’s best to add no more than 15, as SEOs could mark the post as not safe or as spam.

      I recommend only deleting categories and tags no longer used on blog posts. But in answer to your question, yes.

    1. Housekeeping of categories and tags is always a good option, Janis. I tend to do mine in December when the blogging world seems quiet.
      As for coming up with tag words, I ask myself which tags I would use if searching for the post on WordPress.

  7. I recently added a category for Short Stories because I wanted to add a menu for them. Adding a category is easy. Finding all the posts you should have been putting in a category all along is not so easy. Great post, Hugh.

    1. That’s true, Dan. I tend to add a new category to an old post when I’m going through old posts, deciding which ones to delete because they’re outdated and no longer relevant.

    1. Adding categories and tags to all blog posts is important, Jan. I don’t know why some bloggers refuse to add them. It just gives the impression that they don’t care about their readers.

  8. I do the best I can with tags but what I find funny is that on some of my blog posts when I publish they offer me tags to use and I accept but on other posts I am on my own. Very confusing.

    1. Yes, that’s happened to me, too. In one case, I added the tags they suggested and ended up with more than 15 categories and tags combined, so I had to go back into the post and delete some.

  9. You should have pointed out that if you ‘delete’ any categories or tags that you will be penalized by search engines if you don’t add a permanent redirect when deleting (That is if they have been indexed already). You can do that manually or if your host (like mine) they have a feature to do it for you, and I believe there are plugins to do it also.

  10. I use categories and tags all the time. In fact, I think you were the first blogger to teach me about them! This is an excellent tutorial, Hugh. Thanks for your hard work.

    1. I’ve unfollowed several blogs that do not categorise their posts, Colleen. They’re of no help to me if I can’t find what I’m looking for. I’d rather spend my time on blogs that help their readers rather than those where everything is just in one pile to sort through.

    1. Hi Jacqueline, To create a subcategory, first add it as a category. Then, go to the categories page on your blog’s dashboard, click the meatball menu next to the category you just created, toggle off the switch for ‘Top-level Category’, and choose the top-level category you want this subcategory associated with.

      I hope that helps.

  11. Great tutorial and guide for newbies! I try and categorize as well, but I’m not sure if I have good enough of a system 😂. I do try and use very few tags per post, but I’m still not sure I’m using the right ones.

      1. That’s what I’m trying to do. I’ve looked through the WordPress reader and found popular tags to use, so I’ve used those for some of my posts. Thanks!
