If you’ve been blogging for any length of time, but especially if you’re new to blogging, then you’ll probably be familiar with the term ‘content cluster’. But what exactly is that, and why are content clusters important for your blog?

I’m going to share some reasons why I think they are, and also why people are talking about them a lot more these days than perhaps they have in the past, but just a few things to note before we get started.

👉🏻 Want to jump straight to the importance of content clusters? I get it. Click here.

What are content clusters?

A content cluster is a group of blog posts that all revolve around the same topic.

“Well, Anjali, isn’t that what a niche is?”

Yes. And no.

Your niche might be solo travel for women, but you might have a content cluster around a specific city or place. They’re maybe 5 – 10 blog posts around a certain singular idea.

Rather than putting everything there is to know about one topic into one blog post, you’d create more detailed blog posts around different aspects of that topic.

Here’s a really quick example of a content cluster. 

Let’s say Jane is a travel blogger specifically for women, solo travelling. She herself is a solo woman travelling, and one of the places she visits is London, England.

Here are some of the blog posts she might write about London:

1. My two-week Trip to London as a solo traveller
2. Safety tips for exploring London as a solo woman
3. The best cafes to spend the morning at in London
4. Things to do in London for solo women
5. Where to stay in London as a solo female traveller
6. 3 day trips you can take from London
7. I went to 5 West End shows by myself in London and here’s what I learnt
8. Top underrated places to check out in London

I could keep going. But hopefully you get the picture.

It’s not just one blog post about Jane’s 2-week-long trip to London (although she could write about that in a more summary sort of way); it’s 8 (or more!) blog posts that point at different mini-topics within that larger topic, that all interconnect and link to each other.

‘My two-week trip to London as a solo traveller’ might be her anchor blog post, a really beefy, hearty blog post where she outlines all the things she did. Then all the other blog posts are linked in that big one, expanding on the points she makes in it.

It creates this beautiful ecosystem of content around Solo Travel for Women in London.

So, if content clusters are ‘in’ … is SEO dead?

Absolutely not. I keep seeing this type of rhetoric online at the moment, and also when it comes to keywords (more on that below). SEO (Search Engine Optimisation) is not dead, despite the world really jumping on AI and AEO (Answer Engine Optimisation).

We still very much need our blogs to be able to be found on search engines like Google, Bing, wherever else, but we also want them to be found AI platforms. People are searching these days differently, so we need to adapt. 

So, are keywords dead?

Also no. It’s still a really good idea to do your keyword research when it comes to writing blog posts. I did my keyword research for this very blog post.

However, the way keywords are bringing people into our blogs is a bit different these days. People are using both AI and search engines like Google to not just put in words like ‘vanilla cupcake recipe’, but they’re searching for ‘what is the best vanilla cupcake recipe for a beginner baker?’ or ‘can I substitute XYZ for ABC in a vanilla cupcake recipe?.

The way we’re finding our answers these days, and the words that we’re using, is a little different. But we still want to be finding the best keywords for our blogs, knowing that our blogs are going to be found via multiple different channels.

And that has changed a lot over the years.

Blogging looked a bit different back in ‘the day’

One blog post, one keyword, repeat for the next one

I hate to say it, but times way back when I started blogging were easier.

You could write a blog post about ‘Auckland Zoo’ and as long as you had those words throughout your blog posts often, chances were pretty high that people were going to be finding your blog post.

Over the 16+ years I’ve been blogging, I’ve seen that change.

It’s no longer an option to just keyword stuff. We can’t just choose one keyword, write one blog post on the topic, and move on to the next one. It doesn’t work like that anymore. 

And while I did say it was a bit easier … I don’t think I want to go back to those times.

Why? Because I don’t really want to be landing on a blog where there is only one blog post about a certain topic. I want to linger a while; I want to see the writer’s expertise come through; I want to know that, along with their big blog post on everything they thought about XYZ, they have also answered my lingering questions around the topic.

That worked well for a while, but then the cracks began to show

Back in the day, Google rewarded more for keywords and things like backlinks. (Those things are still good, but there’s just more to think about now.)

There was less emphasis on things like topic authority – you could write one blog post about puffins in the North of England and rank for it.

These days, it looks at things like topical authority, brand authority and audience authority. And all those work together to show both Google, other search engines like Bing, and your readers that you actually know what you’re talking about.

And they should stick around and read more of your blog posts.

Now, instead of just one blog post about puffins, Google wants to see that you also share about accommodation near the puffins that people could book. Or the other puffin colonies in the United Kingdom. Or the tours that you went to see the puffins. Or about a puffin event you went to. Whatever it is.

There is more emphasis on a mini-ecosystem of content than there used to be.

Why are content clusters important for your blog?

There are a bunch of reasons why having some really good content clusters for your blog is really important, especially these days.

1. They build topical authority and expertise
2. You get repeat readers
3. AI pulls from more than one source
4. Better longevity
5. Rank for more keywords
6. You’re not starting from zero

They build topical authority and expertise

I think this is one of my favourite reasons having content clusters on your blog is a great idea. You’re building topical authority.

Which is what, exactly? Basically, what it says on the box: authority in a particular topic.

If you only have one or two blog posts on a certain topic, for example, the one time you made sourdough, then it’s hard to become the go-to person in sourdough making. But if you had blog posts that were more along the lines of: 

• I made sourdough for the first time and here’s what happened
• The best flour to use for sourdough
• Tips for making sourdough
• How to get started with sourdough art
• How to create your own flavour of sourdough

Then you’re building a better picture of you and your sourdough – you have more than just one or two blog posts, giving your knowledge on sourdough to the people and to the search engines.

You’re growing that topical authority … on sourdough.

This is especially good for sharing your expertise if you’re blogging for business. If you’re a copywriter, for example, then you can showcase your expertise with a cluster of blog posts that are around copywriting. Or a particular aspect of copywriting. That’s going to build up your topical authority on copywriting but also show that you know what you’re talking about and people should hire you.

You are, in fact, the bee’s knees. 🐝

You get repeat readers

If I land on a blog post about something I’m interested in or need to know information about, and I see that there are a bunch of other related blog posts linked up in that around the same topic … I’m going to be reading them.

I’m going to be clicking through to that blog post about how to create art on my sourdough, and then I wanna know how to make it taste delicious with different flavours.

I’m clicking through, reading more, sticking around.

And so the next time I’m looking for sourdough advice, I’m going to go straight to your blog because I know you have that good content that’s going to help me out.

AI pulls from more than one source

You’ll notice when you’re doing a Google search, or you’re spending time on ChatGPT, Claude, Perplexity … any AI site, that they draw from multiple websites. They’re not just getting from one blog post or one webpage.

Which means if you can create a content cluster around a topic, then AI is going to see that you know your stuff (about sourdough or whatever 😂) and is more likely to recommend your content or pull info from your content because you know what you’re talking about.

Better longevity

One point I heard recently was that if you have one blog post that is about everything you can think of when it comes to making sourdough, and, to make our maths easy, let’s say you get 100 views from that blog post … if the algorithms change or something happens that’s out of your control, there go 100 views.

But if you had 10 blog posts that all only got 10 views, and just one of those blog posts flops or suddenly doesn’t get traffic anymore… you still have 9 other blog posts, bringing in 90 views.

Now, let’s hope that our numbers are bigger than that, but you get what I mean.

A cluster of content around a blog post has more longevity simply because there are blog posts to get traffic from.

Rank for more keywords

Similarly, if you have one blog post that is ranking for one or two keywords, that’s awesome. But if you have a cluster of content that is ranking for 50 – 100 variations of keywords across different blog posts … even.the.flip.better.

And if you get one person in with one keyword, then they’re going to see all those interconnected blog posts and stick around. Another person might get in another way, but they’ll also see the content cluster.

Stunning.

You’re not starting from zero

This idea hit me recently, too. If you have a bit of a plan for your content cluster (whether structured like a Brand, Topic, Audience authority, or less structured), then you never really have to start from scratch.

Going back to our London example with Jane, perhaps every time Jane visits a new city, she knows she’s going to write these four types of blog posts:

1. Everything I did in [city] as a solo female traveller
2. Things to do as a solo female traveller in [city]
3. Safety tips for visiting [city]
4. Where to stay in [city] as a solo woman

That way, every single time she visits somewhere new, she’s already got four blog posts at the ready. Then she might supplement those blog posts with other more specific things about that city (see the list we wrote before to get some more of those ideas).

She (read: you) are never starting from scratch when it comes to content.

Hopefully you can see why content clusters are important

At the end of the day, yes, SEO and keywords are still really important. But so are content clusters. We’re all going to be better off as bloggers going forward if we start thinking in collections of blog posts rather than just one or two on a similar topic.

And yes, I’m still totally working on this myself, and I’m going back to older blog posts and figuring out how I can add to them in new ways and create better content and clusters for my readers (that’s you!).

I’d love to know what you think about this! Are you going to start creating content clusters for your blog? Do you already?
