We live in the age of search engines.

Anytime a potential customer wants to know about your products or services, they are invariably going to search on a search engine like Google.

From finding a product to buying it, search engines are a key way for customers keyword clusters

to connect with businesses and vice versa.

But you already knew that.

And chances are you have already hopped on the content creation bandwagon, creating content, but are lacking the awesome results you thought you’d get once you started targeting keywords one by one.

Finding profitable keywords that can help you rank at the top is the first step to making a good content strategy. But the traditional methods of focusing on one keyword with each piece won't work in the hyper-competitive internet landscape.

To improve your chances of ranking, it's better to focus on related groups of keywords. This approach can enhance how search engines index your content, increasing its visibility for different variations of the same keyword.

In this blog, we will help you understand the concept of keyword clusters and how they can help you build a topic cluster strategy for your company.

What is keyword clustering, and why is it important?

Keyword clustering is the act of grouping similar and related keywords. It is an essential part of any SEO strategy as it enables you to create high-quality content that targets multiple keywords and satisfies the user's intent. By using advanced SEO strategies like keyword clustering, you can stay ahead of the competition and drive more traffic to your web page. For example, let’s say you want to create a keyword cluster for the topic “website development.”

Keyword clusters for website development would look something like this:

All of these keywords are related to each other in the sense that they ask for information about different aspects of website development.

Keyphrase clustering helps you target all the keywords related to a broad topic. Now, a marketer who wants to write content about "website development" can increase their chances of ranking as a website development company by focusing on the above keywords.

Creating such keyword clusters will help you:

  • Find ranking opportunities with a mix of short-tail and long-tail keywords.
  • Establish topical authority in your industry niche.
  • Enhance on-page SEO by including groups of keywords.
  • Improve search engine indexing of content with a solid interlinking strategy.
  • Generate more organic traffic to your website.
  • Produce measurable results from your content planning and creation  efforts.

Keyword clustering is a crucial step in the process of content and search engine optimization. Whether you are a content strategist, writer, editor, or SEO professional, creating keyword clusters will help you get value for your efforts. Overall, keyword clustering is a valuable strategy that can help businesses enhance their online visibility, attract more traffic, and improve conversion rates.

What is a group of keywords called?

A group of keywords is called a keyword set. Keyword sets are used in search engine optimization to help improve the visibility and ranking of a website in search results. Grouping related keywords can help businesses target specific queries and increase traffic to their site.

Glossary: Key terms you need to know

Before you get started with creating keyword clusters, there are a few important terms that you need to know —

  • Topic cluster: A topic cluster is a group of keywords that are related to each other and can be targeted as a single keyword campaign. It allows you to broaden your reach by targeting multiple keywords at once.
  • For a deep dive into topic clusters, refer to this Scalenut blog, “What are Topic Clusters & How to Use it to Improve SEO?
  • Pillar page or Content Hub: A pillar page is a unique and well-written piece of content that specifically targets ranking for a keyword cluster. It provides the visitors with a comprehensive overview of the broad topic with links to get in-depth knowledge via individual cluster blog posts.
  • Want to know more about pillar pages? Refer to this comprehensive Scalenut blog on what is a pillar page and how it can help boost SEO rankings.
  • Cluster blogs or spoke content: Cluster blogs are content pieces that target a specific keyword cluster. They can be long-form, multipart articles with lots of information and links to related content.
  • Anchor text: Anchor text is the keyword phrase that links back from your website to a particular cluster blog post on your topic of interest. It’s important for linking to other related keywords so they show up as search results when people search for those topics.
  • 10X content: 10X content is any piece of content that can help improve your website’s ranking for a keyword cluster by 10 times or more.
  • This means that if you have a cluster targeted towards “content marketing,” the 10X content could include blog posts with insights on SEO best practices and articles on how to drive traffic to your site from social media channels.

Check out this detailed Scalenut blog, “10X Content Pillar Page: What is it and How to Create One,” for more information.

  • Parent topic: The parent topic is the central subject of your keyword cluster and the resultant topic cluster.

Creating a keyword cluster by doing manual research is a time-consuming task.

Marketers need to streamline the process, and that's where keyword clustering tools come in. They use advanced technologies such as AI, NLP, and machine learning to find keyword variations and group them based on their relevance to the main keyword.

However, selecting the right keyword tool can be confusing.
