Keyword Clustering – All You Need to Know

Keyword Clustering

Keywords are an integral part of any search engine optimization (SEO) strategy for businesses online. As keywords are one of the major ranking factors of Google, it would help businesses to know which keywords would grab the attention of search engines and ultimately improve their ranking on search engine result pages (SERPs).

Keyword clustering becomes a part of this journey. But what is it and how can it assist you in leveling up your SEO? Let us find out.

What Are Keyword Clusters? 

The process of grouping hundreds or thousands of keywords into small segments or clusters after identifying which ones go together is termed as keyword clustering. Keyword clusters are a collection of keywords that carry similar intent, and which help search engine algorithms connect the dots and envision a complete picture of a website.

For instance, “SEO strategy” and “SEO content marketing strategy” are two keywords with similar intent. They can be put into one keyword cluster and grouped on a Web page with “SEO content strategy” as its primary content. This page could then be linked to a pillar page with “SEO benefits” which can have its own keyword cluster related to this one.

Why is keyword clustering important? 

Some of the many benefits of keyword clustering include:

  • Increasing search traffic
  • Building topical and domain authority
  • Organizing website structure
  • Streamlining crawling of bots on the website through better internal linking
  • Improving SERP rankings

Creating Topic and Keyword Clusters


1.Create Keyword List

The process of keyword clustering starts with intensive keyword research. You must start off by finding all the primary keywords you want your website to rank for. After you have a collection of primary keywords, for each primary keyword, you should find variations that users search for. These can be topical, related, long-tail keywords, queries, subtopics, and phrases.

As you collect hundreds of keywords, you have begun the keyword clustering process. Make sure that the search intent of the keywords under each group is similar. You should only include keywords in your cluster that will bring in the right type of organic traffic to your website.

2.Group Your Keywords 

Once you have collected the required keywords, you will start seeing which ones relate to the others. You might see the same words within long-tail phrases, synonyms, intent, subtopics, and so on. These patterns will help you recognize which keywords can be clustered together into keyword groups.

If you choose to use one keyword group for a page and it has keywords that are unrelated to each other, it will confuse search engine bots trying to determine your page’s intent. Hence, each keyword group should have a collection of keywords with similar search intent, and semantic relevance. 

3.Create and Optimize Pillar Pages

Once you have created keyword groups, they will provide you with a clear vision of how to put them into use for individual pages on your website. Keyword clusters will generally represent a core topic or the main subject for your Web pages. These pages are called pillar pages.

Creating landing and pillar pages is how you can properly start using the keyword clusters. Each pillar page on your website should implement one or more of your keyword groups, and enhance it with the best practices for on-page SEO. Using content optimization tools and internal linking, you can optimize your pillar pages and reap the rewards of keyword clusters more efficiently.

4.Strengthen Keyword Clusters With Blog Content

As you build your pillar pages, you also need to improve the content and domain authority. To do this, you can build a blog that reinforces and highlights the keyword clusters on your website to the search engine algorithms. As you keep developing more and more blogs, they will start forming “topic clusters”, which can further help your website rankings.

Is Keyword Clustering Really Worth it?

Google’s indexing and Natural Language Processing (NLP) are responsible for determining which websites should rank high on SERPs. Google does the arduous task of understanding millions of different keywords and identifying the search intent of the users.

Keyword clustering is an advanced process in SEO, which can be very effective if implemented properly. It can help Google properly understand your content and its intent along with determining its authority. So, yes, keyword clustering is a worthwhile process for websites.
