Using Categories Tags Effectively

Got a bunch of blog posts piling up with no real organization? We’ve all been there.

Here’s the quick version: Categories are broad topics that act like folders for your blog (think “Travel” or “Recipes”). Tags are specific keywords within those topics (like “Thailand” or “chocolate cake”). Use 1-3 categories per post and 3-7 tags. That’s the sweet spot for keeping things organized without going overboard.

Why bother organizing at all? Because once you’ve published 20, 50, or 100 posts, your blog becomes a maze without a good system. Readers can’t find related content, search engines struggle to understand what your blog’s about, and you’ll waste time hunting for your own posts. A solid category and tag strategy makes everything easier—for you and your audience.

What You’ll Need

Before diving in, make sure you’ve got:

Your Badass Network blog already set up
Access to your WordPress dashboard (badassnetwork.com/yourblog/wp-admin)
A few published posts (or at least some drafts to organize)
A general sense of what topics you’re planning to cover on your blog

Understanding Categories vs. Tags

Okay, this part confuses most people at first. Don’t feel bad if it seems fuzzy—the difference isn’t obvious until you start using them.

Categories are your main filing system. They’re broad, high-level topics that define what your blog covers. Think of them like the sections in a bookstore: Fiction, Non-Fiction, Mystery, Romance. A blog about food might have categories like Recipes, Restaurant Reviews, and Cooking Tips. A personal blog might use Family, Travel, Work Life.

You can have nested categories too—subcategories that sit under parent categories. For example, “Recipes” could have subcategories like “Breakfast,” “Dinner,” or “Desserts.” We’ll get to that later.

Tags are specific details within those categories. They’re keywords that describe the actual content of individual posts. If your post is in the “Recipes” category, tags might include “gluten-free,” “30-minute meals,” or “Italian.” Tags help readers find related posts across different categories.

💡

Real Example

You write a post about making quick Italian pasta for breakfast (weird, but sure). Your category might be “Recipes” (or even “Breakfast” if it’s a subcategory). Your tags could be “pasta,” “Italian,” “quick meals,” “breakfast ideas.”

Categories are required—every post needs at least one. Tags are optional, though we’d recommend using them because they improve navigation and SEO.

ℹ️

Still Unclear?

That’s normal. It makes more sense once you start actually organizing posts.

Planning Your Category Structure

Before you start creating random categories, take a minute to think about your blog’s focus. What topics do you write about? What will readers come here looking for?

Keep it simple. Most blogs work best with 5-10 top-level categories. More than that and you’re creating too many options—readers get overwhelmed and your navigation menu looks cluttered. Fewer than 5 usually means your categories are too broad to be useful.

Write down the main topics you cover (or plan to cover). Be realistic. If you’ve never written about fitness and don’t plan to, don’t create a “Fitness” category just because it sounds good.

❗

Think Long-Term

Will this category still make sense in a year? In three years? You can change categories later, but it’s easier to get them right from the start. I’d recommend starting with broad categories and adding subcategories as your blog grows, rather than creating super-specific categories right away.

Avoid overlap. Each category should be distinct. If you can’t clearly explain the difference between two categories, they should probably be one category. For example, “Travel Stories” and “Travel Adventures” are basically the same thing. Just pick one.

Some bloggers create categories based on content type (“Tutorials,” “News,” “Opinions”) instead of topics. That works too, though topic-based categories usually feel more natural for readers browsing your blog.

Creating Categories

Alright, let’s actually set these up.

From the Posts menu:

Navigate to Categories

Click Posts > Categories in your WordPress dashboard. You’ll see a page with your existing categories on the right and a form to add new ones on the left.

Enter category details

Type your category name in the Name field. Use clear, descriptive names. “Web Design” is better than “Design Stuff.”

The Slug auto-fills based on your name. This becomes part of your URL, so keep it lowercase, hyphenated, and readable. WordPress handles this automatically, so you usually don’t need to change it.

Parent Category is where you’d select a parent if you’re creating a subcategory. Leave it as “None” for top-level categories.

Description is optional. Some themes display category descriptions on category archive pages, but many don’t. We usually skip this unless we know our theme uses it.

Add the category

Click Add New Category. Done. Your new category appears in the list on the right.

Repeat for each category you want to create.

From the Post Editor:

You can also add categories while writing a post, which is honestly how most people do it.

Open any post (or create a new one).
Look at the right sidebar. Find the Categories section. If you don’t see it, click the gear icon in the top-right to show the settings panel.
Click Add New Category at the bottom of the category list.
Type your category name and press Enter. WordPress creates it and assigns it to your current post automatically.

⚠️

Limited Options

This method doesn’t let you set a parent category or description. For that, you’ll need to use Posts > Categories.

Using Subcategories

Subcategories organize content within a broader category. They’re useful once your blog grows, but you don’t need them right away.

Let’s say you run a travel blog with a “Destinations” category. As you publish more posts, you might add subcategories like “Europe,” “Asia,” and “North America” under Destinations. This keeps everything organized without cluttering your main category list.

To create a subcategory:

Go to Posts > Categories.
Fill out the Name and Slug fields like normal.
Under Parent Category, select the category you want this to sit under.
Click Add New Category.

Your subcategory now appears indented under its parent in the category list. Posts assigned to subcategories automatically belong to their parent category too—so a post in “Europe” also counts as being in “Destinations.”

💡

Keep It Shallow

Don’t go more than 2-3 levels deep. Subcategories of subcategories get confusing fast, and most themes don’t display them well anyway.

Choosing the Right Tags

Tags are easier than categories because there’s less structure involved. You’re just adding relevant keywords to help categorize and surface your content.

Be specific. Tags work best when they describe concrete details. “Chocolate cake recipe,” “budget travel tips,” “WordPress plugins,” “productivity hacks”—those are all good tags because they clearly describe what the post covers.

Avoid vague tags like “stuff,” “thoughts,” or “misc.” They don’t help anyone find anything.

Use existing tags when possible. Before creating a new tag, check if you’ve already used something similar. If you’ve tagged one post “social media marketing” and another “social media,” you’re splitting related content. Pick one version and stick with it.

Don’t go overboard. We usually recommend 3-7 tags per post. Some people use 15+ tags thinking it helps with SEO, but it doesn’t—it just makes your tag system messy. Focus on the keywords that genuinely describe your content.

Make tags reusable. A tag you’ll only use once isn’t very useful. Think about whether you’ll write other posts on this topic. If the answer’s no, it’s probably too specific to be a tag. For example, “my trip to Paris in 2023” is too narrow. “Paris travel” works better because you might write multiple Paris-related posts.

ℹ️

It Takes Practice

Yeah, this takes practice. You’ll figure out what works as you publish more content.

Adding Tags to Posts

Super straightforward.

Access the Tags field

Open your post in the editor (or create a new one). Find the Tags section in the right sidebar, usually below Categories.

Add your tags

Type a tag and press Enter. WordPress adds it to the post. Repeat for each tag you want to include.

As you type, WordPress suggests existing tags that match. Click a suggestion to use it, or press Enter to create a new tag.

Tags are comma-separated if you prefer typing them all at once: “travel, budget tips, Europe, backpacking” works just fine. Press Enter after the last one and WordPress splits them into individual tags.

To remove a tag, click the X next to it.

That’s it. Tags don’t have descriptions, parents, or any other settings—just the tag name itself.

Organizing Existing Posts

Already published a bunch of posts without organizing them? No problem. You can add categories and tags to old posts anytime.

One at a time:

Go to Posts > All Posts.
Find the post you want to organize and click Edit.
Add categories and tags in the sidebar like normal.
Click Update to save your changes.

Bulk editing:

If you’ve got a lot of posts to organize, bulk editing saves time.

Go to Posts > All Posts.
Check the boxes next to posts you want to update.
From the Bulk Actions dropdown at the top, select Edit and click Apply.
A bulk edit panel appears. You can add categories here by checking boxes. Tags are trickier—you can add them, but it won’t show existing tags, so be careful not to accidentally replace tags you’ve already set.
Click Update when done.

⚠️

Bulk Editing Limitation

Honestly, bulk editing works better for categories than tags. For tags, we usually edit posts individually to avoid messing things up.

Displaying Categories and Tags

Your categories and tags don’t do much good if readers can’t see them. Most WordPress themes display them automatically, but it’s worth checking.

Category and tag archives:

WordPress creates archive pages for every category and tag. These pages list all posts assigned to that category or tag. Readers can access them by clicking category or tag links on your posts or in your navigation menu.

Visit badassnetwork.com/yourblog/category/your-category-name to see a category archive. For tags, it’s badassnetwork.com/yourblog/tag/your-tag-name.

Adding categories to your navigation menu:

You can add categories to your site’s main menu so readers can browse by topic.

Go to Appearance > Menus.
On the left, find the Categories section. If you don’t see it, click Screen Options at the top and make sure Categories is checked.
Check the categories you want to add and click Add to Menu.
Drag them to position them in your menu structure.
Click Save Menu.

This is pretty useful if your blog focuses on specific topics and you want readers to filter by category right from your menu.

Widgets for sidebars:

Some themes include category or tag cloud widgets in sidebars or footers. Go to Appearance > Widgets to see what’s available. You can usually drag a Categories widget or Tag Cloud widget into your sidebar to display a list or cloud of your categories and tags.

Whether this looks good depends on your theme. Some blogs look cluttered with a big tag cloud. Others benefit from showing categories prominently in the sidebar. It varies.

SEO Benefits of Smart Organization

Search engines pay attention to your category and tag structure. Here’s why it matters.

Better site architecture. Categories create a hierarchy that helps Google understand what your blog covers. When your categories are clear and logical, search engines can index your content more effectively.
Keyword-rich URLs. If you’ve set up permalinks to include category names (under Settings > Permalinks), your post URLs might look like badassnetwork.com/yourblog/recipes/chocolate-cake. That “recipes” part signals to search engines what the post’s about.
Internal linking opportunities. Category and tag archives automatically create internal links between related posts. Internal linking is good for SEO because it helps search engines discover content and shows relationships between topics.
Improved user experience. When readers can easily find related content, they stick around longer. Lower bounce rates and longer session times are positive SEO signals. Categories and tags make your blog more navigable, which keeps people clicking through to more posts.

💡

Don’t Overthink SEO

Don’t overthink this part. Organize your content in a way that makes sense to humans, and the SEO benefits usually follow naturally.

Common Mistakes to Avoid

We’ve seen people mess this up in predictable ways. Here’s what to watch out for.

Too many categories. If you’ve got 30 categories and most of them only have 1-2 posts, you’ve overdone it. Consolidate. Aim for 5-10 main categories, maybe with a few subcategories under the busiest ones.
Using categories and tags interchangeably. They serve different purposes. Categories are broad; tags are specific. Don’t create a “Travel” category and a “travel” tag for the same posts—it’s redundant and confusing.
Creating single-use tags. Tags like “post about my dog Max” aren’t useful because you’ll never use them again. Stick with tags you’ll reuse across multiple posts.
Inconsistent naming. If you tag one post “SEO tips” and another “seo-tips” and a third “SEO Tips,” WordPress treats those as three different tags. Pick a format (usually lowercase, spaces not hyphens) and stick with it.
Not using the Default Category setting. Go to Settings > Writing and set a sensible default category. Otherwise, WordPress assigns “Uncategorized” to any post without a category, which looks unprofessional.
Over-tagging. Adding 20 tags to a post doesn’t help. Focus on 3-7 meaningful tags that actually describe the content.

Most of these mistakes are fixable, but it’s easier to avoid them from the start.

Cleaning Up Your Categories and Tags

If your blog’s been running for a while and your categories and tags are a mess, it’s worth taking the time to clean them up.

Delete unused categories and tags:

Go to Posts > Categories (or Posts > Tags).
Hover over any category or tag. You’ll see how many posts are assigned to it.
If a category or tag has zero posts, click Delete. No harm done.
For categories or tags with only 1-2 posts, consider whether they’re worth keeping. If not, reassign those posts to a more general category or remove the tag, then delete it.

Merge similar categories or tags:

If you’ve got “Social Media” and “Social Media Marketing” as separate categories, merge them.

Go to Posts > All Posts and filter by one of the categories using the dropdown at the top.
Bulk select all posts in that category.
Use Bulk Actions > Edit to add them to the other category.
Update, then go delete the now-empty category.

Same process works for tags.

Rename poorly named categories:

Go to Posts > Categories.
Hover over the category you want to rename and click Edit.
Change the Name field to something better.
Click Update. All posts in that category automatically use the new name.

Cleaning up takes time if you’ve got hundreds of posts, but it’s worth it. A tidy category and tag system makes your blog feel more professional and organized.

Tips We’ve Learned

Start simple, expand later. Don’t create 15 categories on day one. Begin with 3-5 broad categories and add more as your blog grows and you figure out what topics you’re actually covering.
Review your structure periodically. Every few months, look at your categories and tags. Are there new topics you’re writing about that need their own category? Tags you’re using constantly that should be a category instead? Adjust as needed.
Be consistent. Whatever naming convention you choose for categories and tags, stick with it. Title case, sentence case, all lowercase—doesn’t matter, just be consistent.
Make category names navigation-friendly. Your categories might appear in menus, so use names that work as navigation labels. “Blog Posts” is vague. “Marketing Strategies” is clear.
Use tags to connect related posts across categories. If you write about “email marketing” in your Marketing category and also mention it in a Technology category post, tag both with “email marketing.” Readers who click that tag see all related posts, regardless of category.
Don’t stress about getting it perfect. You can change categories and tags anytime. Reorganizing your blog won’t break anything—just redirect old category URLs if you delete popular categories (though honestly, most small blogs don’t need to worry about that).

When Organization Gets Tricky

Some minimalist themes hide them. Check your theme’s settings under Appearance > Customize to see if there’s an option to show post metadata. If not, you can add them manually using widgets (Appearance > Widgets) or by editing your theme—though that’s an advanced topic.

Every post needs at least one category. If you delete a post’s only category, WordPress assigns it to your default category (usually “Uncategorized”). Assign those posts to a proper category, then go to Settings > Writing and change your default category to something more meaningful.

You can’t delete it if it’s your default category. Change the default to something else under Settings > Writing, then you can delete “Uncategorized.” Or just rename it to something more useful—click Edit next to Uncategorized and change the name to match one of your actual topics.

WordPress allows it, but we wouldn’t recommend it. It creates confusion. If “Travel” is a category, don’t also use “travel” as a tag. Find a more specific tag instead, like “travel tips” or “budget travel.”

Go to Posts > Tags. The list shows all your tags with post counts. Click the Count column header to sort by usage. This helps you spot your most popular tags and identify single-use tags to clean up.

The URL for that category archive changes. If anyone’s linked to the old URL or you’ve shared it on social media, those links break. Usually not a huge deal for small blogs, but be aware. You can set up redirects if needed, though that’s more advanced.

What You’ve Accomplished

You now know how to organize posts using categories and tags effectively. You understand the difference between them, how to plan a logical structure, and how to implement it on your Badass Network blog. You’ve also got strategies for cleaning up messy organization and avoiding common mistakes.

Next step: Actually apply this to your blog. Take 20 minutes to review your categories and tags. Delete the junk, consolidate duplicates, and make sure every post is properly organized. Your future self (and your readers) will appreciate it.
