Most bloggers spend hours agonizing over their writing and almost no time thinking about their categories. That’s understandable. Categories feel like a housekeeping task — the kind of thing you set up on day one and never revisit. But that instinct is exactly what causes the problem.
Poorly chosen categories are one of the quietest ways a blog undermines itself. They confuse readers, fragment your content in ways that hurt search visibility, and — perhaps most importantly — signal to anyone browsing your archive that you haven’t thought seriously about what your site is actually for.
The good news is that category structure is fixable. And fixing it is one of those rare improvements that pays dividends across every post you’ve ever written.
What bad categories actually look like
Here’s a list of categories someone was genuinely using on their blog:
- I’ve Been Thinking
- Some Blog Stuff
- More Blog Stuff
- My Thoughts
- About My Car
- Dreams and Wishes
- Useless Information
- Left Over Junk
It’s easy to laugh at this list. But before you do, consider how many professional or semi-professional blogs have categories like “Miscellaneous,” “Random,” “Updates,” or “General” sitting there quietly doing the same damage.
The underlying problem isn’t laziness. It’s that most bloggers create categories in the moment — post by post, as the need arises — rather than designing them with any intention. A category called “My Thoughts” tells a reader nothing about what they’ll find there. It tells a search engine even less.
Why categories matter more now than they did in 2007
When the original article was published, category taxonomy was mostly a UX consideration. Today, it intersects directly with how search engines understand your site’s topical authority.
Google’s approach to evaluating content quality has shifted meaningfully over the past decade. The concept of topical authority — the idea that a site becomes more trustworthy in Google’s eyes when it covers a topic with depth and coherence — is now a core part of how rankings work. Your category structure is, in effect, a map of your topical coverage. A fragmented or incoherent map sends the wrong signal.
Bloggers who see strong results from their content are far more likely to take a strategic approach to structure and organization. Categories aren’t just navigation — they’re part of the architecture that determines whether your content compounds over time or just accumulates.
How to invent categories that actually work
The core challenge people face — and the one that prompted the original article — is that they can’t figure out what their categories should be. They sit down, come up with three or four obvious ones, and then get stuck. This is the point where most people either create vague catch-all categories or give up and leave everything uncategorized.
There’s a more reliable way to approach it. Instead of asking “what categories do I need?”, ask three different questions.
What does my reader come here to accomplish? Categories should map to reader intent, not to your internal filing system. A personal finance blog might have categories like “Getting out of debt,” “Building savings,” and “Investing basics” — not “Finance,” “Money,” and “Budgeting.” The first set tells a reader immediately whether a section is relevant to them. The second set doesn’t.
What topics do I consistently have something to say about? This is the question that weeds out aspirational categories. If you’ve never actually written about a topic, don’t create a category for it. Categories that contain one or two posts (or zero) create dead ends and suggest an abandoned or unfocused blog.
What would I want someone to read before they leave? If a reader lands on one of your posts and wants to go deeper, where should they go? Your categories should answer that question. They’re not just for navigation — they’re for retention.
The common mistakes worth avoiding
A few patterns reliably cause problems, and they’re worth naming directly.
Too many categories. There’s no universal rule, but most focused blogs function well with somewhere between five and twelve categories. More than that, and you’re usually either being too granular or covering too many unrelated topics. Both create dilution — either of reader attention or of topical authority.
Categories that overlap. If a post could reasonably sit in three different categories, your taxonomy needs work. Overlapping categories create confusion about where content lives and can result in the same topics being split across multiple sections, which weakens all of them.
Using categories as tags. WordPress has both categories and tags for a reason. Categories are for broad topic buckets — the main subjects your blog covers. Tags are for more specific, granular descriptors. Many bloggers either ignore tags entirely or use them interchangeably with categories, which muddies the structure.
Never auditing what you have. Categories set in 2018 may not reflect what your blog has become by 2025. If your content has evolved, your taxonomy should too. A periodic review — even just once a year — catches drift before it compounds.
Where to go from here
If you’re reading this because you suspect your categories need work, the next step is simple: pull up your category list and ask honestly whether each one would mean something to a reader who had never visited your site before. If the answer is no — if it’s vague, redundant, or aspirational — note it for revision.
Changing categories in WordPress is straightforward. You can rename them, merge them, and reassign posts in bulk from the Posts screen. It takes less time than you’d expect, and the clarity it creates tends to have a downstream effect on how you think about new content as you write it.
Good categories don’t just organize what you’ve already written. They give you a clearer sense of what you should be writing next — and that clarity, over time, is worth more than most content tactics people spend time chasing.
