You’ve probably heard a lot about keywords and how to use them in your online business. But did you know that keyword clusters are a powerful way to take your keyword strategy to the next level? I only learned of them about a year ago but once I did, it just made perfect sense to use them.
In this post, I’ll explain what keyword clusters are, why they matter, and how you can create and use them to drive more organic traffic to your site.
What Are Keyword Clusters?
At its simplest, a keyword cluster is a group of related keywords that revolve around a central, main keyword (often called the “pillar keyword”). Instead of focusing on just one keyword for each blog post or page, you target a group of related keywords that all contribute to the same overall topic.
For example, let’s say your main keyword is “fitness equipment.” Your cluster keywords might include:
- Best fitness equipment for home workouts
- Affordable fitness equipment for beginners
- Top-rated gym equipment for small spaces
- Fitness equipment for strength training
These keywords are all related to the main topic (fitness equipment) but are more specific and help you rank for multiple variations of the topic.
The goal with keyword clusters is to create a hub-and-spoke model (another concept I learned about just before keyword clusters.) You write one comprehensive “pillar” page or post that covers a broad topic, with several related blog posts (“spokes”) that dive deeper into specific aspects of that topic.
Why Keyword Clusters Matter
Keyword clusters aren’t just a nice-to-have—they’re a must for improving your SEO strategy. Here’s why:
1. Better Rankings on Google
By grouping related keywords together and covering them in-depth, you’re providing Google with more relevant content. Google loves comprehensive content that covers a topic thoroughly, and keyword clusters help signal to search engines that your site is an authority on that topic. The more related content you have, the better your chances of ranking for various variations of the same search query.
2. Increased Organic Traffic
When you target related keywords and create multiple pieces of content around them, you increase the chances that people will find your site. Instead of relying on just one keyword to bring in traffic, keyword clusters let you target multiple related searches, which expands your reach.
3. Improved User Experience
Having a well-organized cluster of content makes it easier for your readers to find exactly what they’re looking for. For example, if someone finds your blog post on “Best Fitness Equipment for Small Spaces,” they might also be interested in “Top Home Gym Equipment for Strength Training” or “Affordable Fitness Equipment for Beginners.” With keyword clusters, you can link all this content together, improving your site’s overall navigation and user experience.
How to Create Keyword Clusters
Now that you know why keyword clusters are important, let’s talk about how to create them. It’s easier than you think!
Step 1: Start with a Core Topic
The first step is to identify your core topic or pillar keyword. This is the broad subject that will anchor your cluster. It should be something relevant to your niche and something that people frequently search for.
Example: If your affiliate site is focused on fitness products, your core topic could be something like:
- “Best Fitness Equipment”
- “Home Gym Essentials”
- “Top Workout Gear for Beginners”
This is your main keyword or pillar topic that will serve as the central page of your cluster.
Step 2: Find Related Keywords (Cluster Keywords)
Next, you’ll need to find a bunch of related keywords that you can target in your cluster. These are the long-tail keywords or variations of your main topic.
There are a few ways to find these related keywords:
- Keyword Research Tools: Use tools like Google Keyword Planner, Ahrefs, Ubersuggest, or SEMrush to get keyword suggestions related to your core topic.
- Google Search: Type your main keyword into Google and look at the “related searches” at the bottom of the page. These are often good ideas for cluster keywords.
- Competitor Research: See what your competitors are ranking for and check out their keyword strategy.
- Answer the Public: This is a great tool for finding questions people are asking around your topic. You can target those as cluster keywords.
For example, if your core topic is “Best Fitness Equipment,” some cluster keywords could be:
- Best fitness equipment for home gyms
- Affordable fitness equipment for small apartments
- Best dumbbells for home workouts
- Best exercise bikes for cardio
These keywords all relate to your core topic, but they focus on specific aspects, such as types of equipment or different fitness needs.
Step 3: Create Your Content
Now that you have your core topic and cluster keywords, it’s time to create your content. Here’s how you can structure it:
- Pillar Content (Main Topic): Write a comprehensive, in-depth post that covers your core topic in detail. For example, if your pillar topic is “Best Fitness Equipment for Home Workouts,” your post should be long and cover a wide variety of fitness equipment options, benefits, and tips.
- Cluster Content (Supporting Posts): For each of your cluster keywords, create a more focused piece of content. These should be standalone blog posts that go deeper into specific aspects of the main topic. For example:
- “Top 10 Affordable Fitness Equipment for Small Spaces”
- “How to Choose the Best Dumbbells for Your Home Gym”
- “Best Exercise Bikes for Home Use: A Complete Guide”
Step 4: Link Your Content Together
Once your pillar and cluster content is ready, you need to link them together. This is where the magic happens!
- Link from the cluster posts to the pillar post: In each of your supporting posts, link to the main pillar post so readers can access the broader content.
- Link from the pillar post to the cluster posts: Similarly, in your main pillar post, link to the supporting cluster posts to help users navigate through more specific content on your site.
This internal linking structure shows Google that your content is related and helps search engines understand the context and hierarchy of your pages.
Step 5: Monitor and Optimize
Once your content is live, don’t just leave it there. You need to monitor its performance and make sure your keyword clusters are driving the traffic you want.
- Use Google Search Console to track which keywords are bringing traffic to your cluster pages.
- Check your rankings: Are your pillar posts ranking for the main keyword? Are your cluster posts ranking for their respective keywords?
- Update and refresh your content: SEO is an ongoing process. Over time, make sure to update your posts with new information and optimize them for additional keywords.
Keyword clusters are a powerful strategy that can take your SEO game to the next level. When you organize your content around a central topic and group related keywords together, you increase your chances of ranking higher on Google, driving more traffic to your site, and improving the overall user experience. It’s a smart, scalable strategy that can help you build a strong, organized content structure while targeting multiple search queries.
So, think beyond just one keyword and start thinking in clusters. With a little planning and strategy, keyword clusters can be the key to smarter, more effective SEO.
