Topic Clusters – a Road to Better Content Architecture

Google changes their algorithm hundreds of times per year. Most of these changes are only small, however every so often they release a much larger and more impactful change. One of the most recent is changing their algorithm to work in favour of topic-based content to serve the users intent. To keep up with the change, we need to think of our content strategies differently and work using a topic cluster model.

Topic clusters and pillar pages

A pillar page is a page consisting of a core topic. This page should be thought of as a “main hub” of content for a certain topic and is typically a service or sales page. Content cluster pages related to this core topic should link back to this page, as well as linking to each other. Content cluster pages go into more depth of the different areas mentioned on a pillar page. These can be thought of as subtopics.

The linking between the pages helps indicate to search engines like Google that a pillar page has more authority, helping to rank it higher over time. Think of this model as a way of structuring and organising your websites content.


Topic Clusters Model


Let’s look at an example of how topic clusters can be achieved. An online protein and supplements store has a popular line of protein powder. To help build authority and ranking power around the protein powder page, content cluster pages are built around it focusing on topics such as “Benefits of Protein Powder” and “Protein Powder Recipes”. The below example visualises how this would look.

Cluster content topics

There are many online resources available to you if you’re struggling to come up with topic ideas.

  • Keyword research
    Conducting keyword research is a great way to find search terms people are actually searching for in Google, in turn helping you figure out what sort of information your potential customers are looking for and want answers to. A great tool for keyword research is Moz’s Keyword Explorer, (available to Moz Pro users).Below is an example of suggested keywords for “Protein Powder”.

Google’s Keyword Planner is another efficient tool to help with topic ideas. Working in a similar way to the Moz Keyword Explorer, the keyword planner gives you the monthly search volume along with suggested keywords.

  • Google and the searcher’s intent
    When typing a search query into Google, the results will appear based on what Google determines will serve you the most relevant answer. Google now also presents you with related search terms. Based on what you may search for next. This can be an extremely helpful way to find new content ideas for future articles, helping you to build out your topic clusters.Below is an example of “related searches” Google presents you when you scroll to the bottom of the search results page for protein powder recipes.
