How to Use ChatGPT to Make an SEO Keyword Cluster (Prompt)

In the world of SEO, good keyword research helps your website show up better on search engines. Even though many people use regular keyword tools, adding ChatGPT can make a big difference.
Today, we’ll show you how to use ChatGPT for keyword research by creating a keyword cluster. This is essential when trying to cover a large range of topics on your blog to rank.
Keyword Cluster ChatGPT Prompt
Now, let’s make a keyword cluster using ChatGPT.
Using the prompt:
This will get ChatGPT to make a keyword list that’s well-organized.

For example we can use the prompt to replace [TOPIC] with photography. If you use this prompt, ChatGPT might group keywords under labels like “Types of Photography”, “Photography Tools”, “Taking Photos”, “Types of Photos”, and more. This helps you plan and write your content in a better way.
Conclusion
Adding ChatGPT to your keyword research can help a lot. It’s great for getting new keyword ideas, learning about related topics, and making a full keyword cluster. But remember, ChatGPT doesn’t replace your usual keyword tools (like RightBlogger’s keyword research tool). It’s just an extra helper in the keyword research process. By using ChatGPT and your other tools together, you can find new ways to make your website show up better on search engines.

What is a keyword cluster, and why does it help SEO?
A keyword cluster is a group of related keywords that fit under one main topic. You use the main keyword for a “pillar” page, then write supporting posts for the related keywords.
This helps SEO because search engines can see you cover a topic in a full, organized way. It also helps you avoid writing random posts that do not connect.
Clusters can improve internal linking and make it easier for readers to find what they need. Over time, this can help more pages rank, not just one.

What prompt should I use in ChatGPT to create a keyword cluster?
Use a simple prompt that tells ChatGPT the parent keyword and asks it to group related keywords. The post’s prompt works well: “Create a keyword cluster for the parent keyword: [TOPIC]. Cluster the keywords into groups based on their relevance.”
Replace [TOPIC] with your main keyword, like “photography” or “meal prep.” Then ask for 5 to 10 groups with 5 to 15 keywords per group if you want more detail.
For cleaner results, add a format request like “Return as a table with Group Name and Keywords.” You can also ask for search intent labels like informational, commercial, or transactional.
After you get the list, pick one group to build your next content plan. This keeps your blog focused and makes it easier to map keywords to real articles.
How do I check if ChatGPT’s keyword ideas are worth targeting?
Treat ChatGPT’s list as ideas, not final choices. You still need to confirm search demand and ranking difficulty with a keyword tool.
A fast workflow is to copy the cluster into a research tool and check volume, competition, and related queries. RightBlogger’s Keyword Research Tool is built for this step.
Also check intent. Make sure the keyword matches what your post will actually answer, like “how to” for guides or “best” for comparisons.
Finally, pick a mix of easier long tail keywords and a few bigger terms. That mix helps you get earlier wins while you build authority.
How many keywords should be in one cluster, and how do I turn it into content?
A good starter cluster is 20 to 50 keywords grouped into 5 to 10 categories. That is usually enough to plan several weeks of content without getting overwhelmed.
Start with one pillar post targeting the parent keyword. Then write supporting posts for each group and link them back to the pillar.
Keep each article focused on one main keyword and a few close variations. This reduces keyword cannibalization, which is when multiple posts compete for the same term.
If you want to expand faster, you can pull more question style keywords using a tool like People Also Ask.
Is there a faster way to create keyword clusters without using ChatGPT manually?
Yes. If you want the cluster done for you, RightBlogger has a dedicated Keyword Cluster Tool that builds clusters quickly.
This saves time because you do not have to keep rewriting prompts or cleaning up messy output. It is also easier to reuse the same process across different topics.
A simple workflow is: generate a cluster, validate the best terms, then outline and write your posts. Once you have your target keywords, you can draft content with the RightBlogger AI Article Writer and keep the tone consistent.
Using tools for clustering and writing helps you publish more often without losing structure. That structure is what helps SEO over the long run.
