How to Use Keyword Clustering To Optimize Your Content For SEO

We all know that keywords are essential in optimizing your site for higher results on search engines. It was once common to select a single keyword to optimize every content. However, with more advanced techniques for optimizing search engines, designing for keyword clusters have become a standard SEO procedure.

Google has become more adept in understanding content, and your keyword strategy needs to be more sophisticated. Utilizing a cluster model for keywords to help guide your overall content strategy could improve your search engine rankings and aid in gaining a competitive edge over your competition.

What is Keyword Clustering? How Does Keyword Clustering Work?

Clustering will give you an idea of how you can arrange and group the relevant keywords for each page you’d like to build for your site based on the top SERPs. It is straightforward to determine ways to improve your website’s performance in its depth, comprehensiveness, and more search-engine-friendly in just four steps. Bots create and send multiple automated queries to chosen search engines, gather data, and matches webpages analyzed from SERPs to each search term. If the search engine you select examines the same web pages with various keywords and has multiple matches, the bot will put these keywords together. You can set the level of clustering to trigger clustering of keywords. If there is no match for the search terms at the top of SERPs, they are divided.

Why should you bother using keyword groups?

A single web page could rank for a variety of keywords. Why aren’t we focusing on creating and optimizing content to target hundreds of related and similar keywords?

Why should you target just one keyword in one piece of text when you could focus on 20? The power of clustering keywords to get more organic traffic is not just not widely recognized; it’s also neglected. In this article, I’ll discuss with you the exclusive method we’ve invented to group keywords so that you don’t have to do the task yourself. But can increase the number of keywords your incredible content will be ranked for.

Step 1. Keyword collection

Before we can begin putting Keywords into Clusters first, we require a database of keywords to sort from.

Our job during this first phase is to search for each possible word. While doing so, we’ll get inadvertently apprehensive about several unrelated keywords (thank you, Keyword Planner!). It’s much better to have a wide range of pertinent and lengthy-tail keywords (and the ability to eliminate the irrelevant ones) rather than having only a small number of keywords to choose from. We suggest taking keywords from 8-12 sources. These sources include:

  • Your competition
  • Tools for Third-Party Data (Moz, Ahrefs, SEMrush AnswerThePublic, Moz, etc.)
  • Your existing data in Google Search Console/Google Analytics
  • Thinking of your ideas and testing them against your ideas

·      Combining keywords

Autocomplete suggestions and “Searches related to” from Google There are plenty of resources for collecting keywords, and research tools are available now than they did in the past. The goal is to become so vast that we will never need to return and “find more keywords” shortly unless, of course, there’s a new subject we’re looking at. The guide’s prequel will go over keyword collection in greater detail. Let’s say for now that you’ve spent the last few hours gathering an extensive list of keywords. You’ve removed duplicates and now have some reliable data on search volume.

Step 2.  Keyword Analysis

Now that you’ve got an inexplicably extensive list of 1000+ keywords, let’s transform it into something useful. The first step is the Keyword. What exactly does that mean?

Each keyword is separated into its components terms that make up the keyword to determine which words are most frequently used. For instance, the keyword: “best natural protein powder” is composed of four words: “best,” “natural,” “protein,” and “powder.” Once we separate each term into individual components, we can better analyze and comprehend what words (as subcomponents of keywords) are the most frequently used in our database of keywords.

·      Here’s an example of 3 keywords:

  • the best protein powder made from natural sources
  • most powerful natural anti-inflammatory
  • How to create natural deodorant.

Have a closer look, and you’ll see that the word “natural” occurs in all three of these keywords. If this word often occurs throughout our lengthy collection of key terms, it will be essential when we begin to group our keywords.

Methods of Keyword Clustering

·      Soft Clustering

The tool chooses the query with the highest number of searches in the search results. All other queries are compared to the one that is selected. The tool explicitly examines the top 10 effects for each of the keywords. If the amount of matches URLs is greater than the precision of the keyword grouping set (from one to nine), The keywords are placed in one group. This method is suggested for niches with the low competition since it lets you make a bigger cluster of queries. However, it does not eliminate the possibility of adding unrelated questions to your cluster.

·      Hard Clustering

The service chooses one of the queries from the database and then compares all other queries against it. If the total number of matches URLs is greater than the accuracy of the keyword grouping set (from 1-9), The keywords are put into a group. The next queries will be checked against the ones already in the group, and after that, all questions within the group have the appropriate URLs. This method is suggested for niches with high competition. It offers the highest degree of accuracy and eliminates adding a non-relevant query in the group.

·      Manual Vs. Automated Clustering

There are many methods to automatize the process of grouping, but some prefer to do it manually, with the help of Excel or similar programs. It’s fine if you have a hundred words but when your research for the project results in many thousands of words, consider how much time it will take to manage them all manually. Manual clustering requires you to divide each keyword into terms, determine their meaning, and then create lists of phrases based on the criteria you want to use.

With the right tools you’ll be able to see the keywords you’ve chosen and how you can organize them into useful groups and without looking through every query you’ve gathered.


With some effort, time, and knowledge, using keywords clustering models can improve any overall marketing plan for digital. Understanding what keywords and content resonate with potential customers and returning ones is vital to stay relevant and relevant within your field. It’s also crucial to earning those organic visits and sales you need to increase your sales.
