Are Topic Clusters The Next Big SEO Revolution of 21st Century?

Topic clusters are the future of SEO since they turn a website into an expert on a particular subject. According to SEO experts, Google recently modified its algorithm to favor topic-based content.

SEO and marketing experts are now looking for new ways to connect linked information into “topic clusters”.

SEO is increasingly moving toward a topic cluster paradigm, in which a single “pillar” page serves as the main center of material for a broad topic, and several content pages connected to that topic link back to the pillar page and each other. This linking action informs search engines that the pillar page is an expert on the subject, and the page may rank higher and higher for the subject it addresses over time. At its most basic level, the topic cluster model organizes a site’s content pages through a cleaner and more purposeful site architecture.

What are Topic Clusters?

“A topic cluster is mostly a collection of interconnected web pages centred on a single pillar page.”

Three components of topic clusters

A Topic Cluster is a type of material arrangement that is based on changes in how people conduct online searches and how search engines respond to these queries.

The words “topic” and “cluster” literally mean “subject” and “group,” respectively. As a result, Topic Clusters are collections of structured content in groups around a central theme and are linked together.

The evolution of SEO in 2021 necessitates that websites become “true experts” in their primary topic, as defined by Google. This entails becoming an authority on a particular subject.

A Short History

Keywords reigned supreme in the early 1990s. Find an up-and-coming hot keyword and build a complete web page around it to achieve high search engine rankings. That worked for over a decade.

The Challenge:

Web developers in the 1990s designed a home page based on numerous keywords. People discovered a thousand long-tail variations of the keyword after adding content to target the core keywords. As a result, people continued to write large amounts of blog posts and website material to attract search traffic. Sites become clogged, repetitious, and chaotic as a result.

Keywords were devalued in 2018 in favor of topic-based content. Today’s search engine questions (queries) focus on a topic clusters rather than a keyword. However, high-quality content is significantly important for any website.

When answering search queries, a Search Engine Results Page (SERP) looks for the most authoritative and reputable sources of information.

Google now favors authoritative material written by “genuine topic experts” over content mills that mass produce content for websites and blogs. Quality material must cite good sources and references, according to the Google Quality Guidelines.

“Content reigns supreme. It’s absolutely correct. The content of a website, more than its items, is what draws visitors.”

According to TechKnowSys, an industry leader in SEO and content marketing.

What’s the Difference between Keywords and a Topic cluster?

For long years, keywords reigned supreme since they were made up of only one word or a brief phrase that search engines could quickly find. The difference between Keywords and topic clusters are as the following:-

  • Keywords serve as quick summaries of entire web pages. KEYWORDS do not assist in the organization of information; TOPIC CLUSTERS do. Keywords can display distinct search keywords used to find the same result, but they don’t capture the semantic relationship like topic clusters do.
  • Search engines have evolved to the point where they can now index a complete web page’s content to answer a question (query) or search an entire field (topic). As a result, keywords are no longer as important as topic clusters have become for SEO.

What do Topic Clusters have to do with SEO?

As technology changes the way that people use the internet, so must a successful marketing strategy adapt to meet needs and behaviors. Search engines are getting smarter, and the people using them are getting better at finding the content they want, and so long-tail keyword content production is kind of in the stone age of SEO.

To throw a wide net over search engine users, the current SEO strategy involves inbound marketing teams loading their company’s website with the blog after blog with material that employs different combinations of essentially the same long-tail keyword searches. This method worked… for a while. However, now that Google’s web crawlers and content ranking system use new algorithms and software, many websites are left with an unstructured graveyard of underperforming information, which has a detrimental influence on their search engine trustworthiness.

How do Topic Clusters affect SEO strategies?

SEO teams used to isolate 10 to 20 major keywords relevant to their sector and aim to monopolize them just a few years ago. However, thousands of long-tail variations of nearly every keyword configuration are being searched every minute from all over the world.

Filling your website with blogs in an attempt to keep up with keyword popularity is no longer enough to maintain your site operating well. While some of the greatest classic SEO methods are still worthwhile (particularly those connected to local, video search, and voice search), it’s time to start planning forward. The culture of SEO has shifted from keyword to topic cluster as a result of technological advancements.

What is the mechanism behind Topic Clusters?

Because Topic Clusters are a structured structure, they must be implemented systematically so that it is possible to comprehend what is being done, have a broad view of the strategy, and, of course, track the results. A Topic Cluster contains three key aspects, to put it simply:

This network of ordered material will show search engines the relevancy of your pages, improving your search engine results, and playing a key role in your SEO strategy.

Putting Together a Topic Cluster

1. The Post Pillar

The Post Pillar is the focal point of the collection of materials. It serves as a key support structure for this group’s activities, as its name implies.

But how do you specify what a content group’s pillar post will be?

The usual rule is that the pillar’s material must completely cover a topic.

In practice, this means that the pillar post will be based on a keyword that is usually linked to a broader problem. Although these keywords tend to wind up being head tails and funnel top in the majority of situations, it’s vital not to get the definition mixed up and think that a Post Pillar will always follow this pattern.

Furthermore, Post Pillar must be highly relevant to your ranking and conversion strategy, addressing critical concerns for your business that are directly tied to business goals. Thus, Post Pillar refers to how important an issue is for your company and how much you intend to work. It may be that the pillar is relevant to you, but not for other strategies.

Remember to conduct this prior analysis of the most significant topics and should receive more attention from your content efforts and improvements.

More precise topics, which typically deal with long-tail keywords, are not posts pillars, according to a reasonable proposal. Even though they are critical to your plan, they cannot serve as a pillar since they lack the breadth of concerns and support that other posts require.

2. Clusters

After you’ve defined your pillar, it’s time to consider the contents that will surround it or the collection of materials that will work together to turn your pillar into a page that is relevant to the search engine and thus appear among the first SERP results.

Clusters can (and often should) be more specific than pillars because they deal with bigger topics. But, once again, caution is advised. Even if this propensity occurs, do not assume that this signifies exactly what they are half or funnel bottom contents.

When defining your clusters, they must be addressed in a precise manner, rather than relying on other factors, as the pillar does. The cluster must dedicate itself to a single problem and address it as comprehensively as feasible. Furthermore, it is critical that the pillar’s contents refer to and explore all of the clusters, even if only briefly.

In general, each pillar should have between 10 and 30 clusters, though there is no set number.

For illustration, if the Post Pillar is the keyword “content marketing”, we can think of various alternative clusters, such as:

  • Copywriting;
  • Content marketing tactics;
  • Corporate blogs;
  • Optimization of content;
  • how to get started with content marketing;
  • Books on content marketing;
  • Platform for content marketing, etc

To find your clusters, it is recommended to conduct a keyword search and identify those that can be incorporated into your content. This entire content on keywords and tools will teach you how to achieve it.

3. Keyword Dossier

Ready, now you know how to define a pillar and how to choose the clusters. But the work does not end there!

The pillar and its clusters must be connected to show the seeker that you are affiliated with a company and that you are an expert on the topic. This interconnection must be formed from the linkages, which brings us to the next topic, Internal Links.

 4. Internal Linking

Backlinks are one of the most essential ranking criteria for Google; thus, getting them is one of the most crucial aims of a solid SEO plan. Many professionals, however, overlook the importance of the internal link in the strategy’s success. Internal links operate to demonstrate the search engine, the organization of your more significant pages, and the authority of your company in a matter; however, they do not have the same ranking value as an external link.

Internal linkages are therefore essential in the structure of Topic Clusters. It should not, however, be done in any way. These connections must be planned in the following manner:

  • The cluster must be connected to its pillar at all times. Although it is not required, it is preferred that the first link is to the pillar page. It’s also crucial to use the correct anchor.
  • The pillar must reconnect with the cluster. You won’t be able to (or should not) devote the same amount of attention to the cluster in the pillar’s topic as you would to the topic’s exclusive content. As a result, add a “learn more” button or a simple anchor to the cluster.

As a result, you establish a content network around your main material, which connects it and emphasizes its overall relevance to the search engine.

SEO Strategy for Topic Clusters

Here’s a quick rundown of how SEO Strategy for topic clusters works.

  • Focuses on subjects rather than keywords.                    
  • The major issue is outlined on the Pillar Page.
  • Clusters are formed by web pages that are focused on specific long tail keywords.
  • Each cluster page has a connection to the Pillar Page’s main page and vice versa.
  • Because there is a semantic relationship between the primary topic and the cluster sub-topics, Google web crawlers notice the topic clusters referring to the Pillar Page. Because of its excellent quality material, the Pillar Page is now considered a “authority” on the subject. This should improve the overall search ranking of the website.

As a result, each grouping focuses on a specific topic. The Pillar gives a general overview of the subject. The Pillar then links to a collection of clusters, each focusing on a single long-tail search term and linking back to the Pillar page. Because of these links, web crawlers rate them higher as an “authority” site, indicating that they are a trustworthy and respected source of information based on their high-quality content.

Tactical Advice on How to Begin Using Topic Clusters

Choosing a topic to focus on and developing cluster content plans can be difficult, and reviewing historical material, especially if your firm has a large archive, can be excruciating. Today, we have a few ideas for how to organize and create topic clusters.

  • Make a list of five to ten major issues that your buyer persona faces. To collect data, use surveys, conduct interviews, and conduct secondary research within online communities as needed.
  • Assemble each problem into large topic groups.
  • Using keyword research, flesh out each of the primary subjects with subtopics.
  • Make a list of content ideas that correspond to each of the main subjects and corresponding subtopics topics.
  • Conduct industry and competitor research to back up each notion.
  • Generate content, track its effectiveness, and improve it.

Teams can use a sheet like the one below to keep track of content and links inside a topic cluster. Some of the categories may not be essential depending on the topic’s complexity and the number of sites you’re linking to.


Creating content that your ideal customers want to view is the future of SEO and inbound marketing. In the end, this shift in how search engines interpret and rank information gives people more control over their search results. As a result, previous techniques such as producing information that can be read by web crawlers would no longer be effective. Instead of looking at the amount or distinctiveness of keywords, search engines now look at the intent of your website.

When you’re writing material, keep in mind that you’re writing for humans. Don’t be concerned about cramming long-tail keywords in. Simply ensure that your content is useful, that your knowledge is unique, and that it addresses specific “buyer problems” that consumers may love to see.

This shift from keyword-focused content to topic clusters will result in you producing more meaningful content, which will help your website rank higher in search engines, provide better service to your customers, and help your website’s organization push your content creation forward in a way that benefits your business.
