How Topic Clusters Make Content Marketing More Effective in 2019

SEO is evolving, and consumers of content are directly contributing to this change. Clearly, not breaking news but something to be aware of as it impacts your content strategy.

Search engines are perpetually making changes to their algorithms to focus on providing the most relevant content to today’s more “intent” focused searches, rather than just blindly rank content on a simple keyword basis. But what does this mean for you as a marketer and/or content creator? How does it affect you?


There are 3 main areas in which you will need to focus:

  1. You will now need to focus on what your audience is actually looking for. In other words, what is their "intent" for performing a search. Your content will need to provide answers and value to address this intent. This in turn will generate higher quality traffic and leads.
  2. You will have to place greater emphasis on interlinking (creating content clusters.) This will allow your content to be organized in a fashion that is easy to find by your audience, and easy to crawl by Google.
  3. You will have to change the way you monitor content marketing performance. The increasing importance of SEO and intent driven content, you will need to be able to monitor your performance at a glance, quickly pinpoint what is not working, find out why, and solve quickly. 


The Emergence of Topic-Based Content.


In simple terms, Google has begun favoring topic-based content. This has led to the emergence of topic cluster models in content marketing, where marketers and content creators can leverage internal and relevant linking to boost certain topic SERPs.


What is a Topic Cluster? 

For those who are not aware of what a topic cluster model is, we’ll briefly explain. The model focuses on 2 main things, the first being a central topic known as the “content pillar.”

This is oftentimes a page that acts as a central hub that explains a core topic in more detail. For example, let’s say that our content pillar is SEO. 

The second piece of the puzzle is a subtopic. These are basically content pieces that are related to the pillar. For instance, “10 SEO Strategies,” “How to measure ROI from SEO,” “SEO vs PPC” are all subtopics to the content pillar.

These subtopics link back to the main page, essentially creating a cluster that focuses on all you need to know about a specific topic.

If you still need some explaining, HubSpot has a great and simple video underlining how the cluster methodology works.

Why Is This Important?

This linking action is not only to guide your audience to and from relevant content pieces, it also helps you keep your site clean and organized, making navigation an easy and pleasant experience for visitors.

More importantly, the internal linking structure of a cluster model is a strong indication that the central page or “pillar” is an authority on the topic.

This is something search engines take into consideration, and might even increase the page’s rankings over time. If a continuous strong signal is sent to search engines that the pillar page is an authority on the topic, over time, the page may start to rank higher and higher for the topic.


A Visual Representation

Before content marketers started to adapt to topic clusters, it would be safe to assume that most websites looked a bit like this:

  • The main URL hosts the blog
  • The blog hosts every single piece of content in no organized manner (like papers thrown into a drawer instead of them being organized in files and folders.)

HubSpot does a great job explaining this. (Image below)

While this is (somewhat) acceptable for a site with very few posts, as more content is created, it just becomes “chaos” with no actual organization. This not only takes away from the user experience, it also makes it much harder for search engines to sift through, and quickly crawl your pages, which can lead to potentially reduced SERPs.

Another important thing to note is that, as you create content around a similar topic, on a pure keyword model, these posts will eventually begin to compete with themselves to get found by your audience, and search engines; ultimately leading to a form of cannibalization.

With topic clusters, everything is organized, and arranged in a way that lets search engines know which posts should be prioritized and displayed for the main topic, and organizes all the pages related to that pillar in one interlinked cluster like seen below.

The above illustration shows search engines that there is true breadth and depth surrounding a central topic, which in turn can also do wonders for your authority.

Search engines take everything into consideration. Shifting to topic cluster model can be beneficial for your content marketing efforts and can reward you with healthier SERPs.


How Do You Create A Topic Cluster?

The first and most important thing to do when creating a topic cluster is determining your pillar. Typically, most of us probably immediately go do some keyword research.

While this is in fact needed (and important), it is not the whole story. You'll also need to start thinking about topics. This could be either from longtail keywords, trending subjects in your niche, or something that is evergreen and always evolving. Whichever the case, your pillar needs to focus on the main topic.

On the subject of pillars, note that it will need to cover a core topic that is broad enough to have the subtopics link back to it.

Another good determinant of a content acting as a pillar is its ability to answer all possible questions for a specific topic. This is what will make it suitable for tying all other related content. 

Remember: The pillar needs to be broad, so if you see a post/page is focused on a specific longtail keyword then it is not suitable to be a pillar. 

Using the example from before, let’s say that our pillar page is on SEO. From there you would perform normal research for related topics or long-tail keywords. (Let's say “how to create an SEO ready post.”)

The next step would be to create content on those subtopics, and ultimately link back to the pillar page to finalize your cluster. If you already have relevant content, be sure to update it by including an internal link back to the core pillar.

Note: When linking content together, each piece of the cluster needs to be linked at least once with the same anchor text in order to let search engines know that they are all part of the same topic cluster.


How To Get Started 

If your company has fairly few content pieces, creating content pillars can be a quick and easy way of organizing your posts. If however, you have a massive inventory of hundreds of pieces, this process can be downright painful. So, what can you do?


Step 1: Map out the core problems you aim to solve for your personas.

Step 2:  Extract your existing posts to an MS Excel file

Step 3: Sort by either keyword, tags, or anything else that can signify the core topic of the post (ideally these topics should align with your persona’s pain points)

Step 4: If you don’t have one already, create a pillar post that encompasses all potential answers for the core interests of your audience.

Step 5: Copy the link of the pillar post and incorporate it in each corresponding subtopic article. (Remember to use the same hyperlinked text each time to make it easier for crawlers to identify and understand)

Step 6: Monitor, make necessary adjustments, and manage weekly (adding new relevant posts to the cluster before more pile on)


The above steps are in fact all manual and might take some time to finalize. If you want to shed some time off the process, you can consider using a tool to make linking, searching, and visualizing everything much faster (and easier).

One of our personal favorites (and one we are using at the moment) is HubSpot’s Content Strategy tool. While this will boost the efficiency of the process significantly, it will still require some time on your part. However, creating clusters is a very worthwhile investment that will not only boost your SERPs, it will also make for a much better user experience on your site.


How To Monitor Everything At A Glance

There are 2 excellent ways of monitoring the performance of your newly built content clusters. The first method is by using HubSpot’s Content Strategy tool we just mentioned, and the second is by using a Google Analytics Dashboard.


Let's start with Hubspot. After logging-in, navigate to the Marketing Tab, Select Planning and Strategy, and click on SEO.

Hubspot Content Strategy 1

From there, you will be directed to a content dashboard where you can monitor the performance of each cluster at a glance. Here you can edit the columns based on the information you would like to see, the date range, and make edits or add additional topics.

If you wish for more analytical insight you can click on View Topic Analytics which will take you to the screen below.

Similarly to the previous screen, you can sort all information as you please. If you want to look at a specific topic cluster, all you have to do is click on the topic of interest. This will allow you to see the performance of  each specific content piece related to that topic, along with its performance based on the date and columns you've set previously. 


Google Analytics

Let's move on to Google Analytics. In digital marketing, this is an essential tool for analyzing content, but unless you know what you are doing, it might get a bit jarring, and even time consuming. That's where analytical dashboards come in.

With a Google Analytics dashboard you can essentially monitor all your linked content from one place. In the example above, we can see:

  • Which search engines are driving use the most traffic
  • Total visits from SEO
  • Specific pages that generate organic traffic (this can be grouped with only your clusters)
  • Overview of all traffic coming in


The dashboard above is only the tip of the iceberg. There are dozens of highly customizable dashboards that can fit your every need. These dashboards, at a glance, can help measure your key performance indicators such as: total traffic, traffic sources, time on site, bounce rates, performance over time, organic vs. paid performance and so much more.
