SEO Landscape Evolves with the Growing Influence of Content Clusters

Content clusters are changing how websites rank and thrive in search results. But what is SEO and what are content clusters?

SEO is the process of optimising a website for search engines so that it ranks well when someone enters a search term. Content is the on-page stuff that people read or watch or interact with. Think product descriptions or blogs, for example. Content is the cornerstone of digital marketing.

What Are Content Clusters?

By organising content into structured groups around a central topic, you can give your SEO a boost and provide better user experiences. And better user experiences is something that search engines like.

Think of it as creating a hub of knowledge—your pillar page acts as the hub, while supporting pages cover related subtopics.

Clusters are an SEO strategy that organises related content around a central pillar page. The pillar page covers the main topic comprehensively, while the supporting content explores subtopics in greater detail.

Unlike traditional blog structures, where posts often stand alone, clusters link everything together. This signals to search engines that your website is a trusted authority on a specific subject.

For example, if your main topic is “SEO” your pillar page might be “A Complete Guide to SEO.” Supporting pages could include posts like “What is on-page SEO?” “Technical SEO,” or “What is Local SEO?” Tie these in with well-researched keywords and you’ll be onto a content winner.

When search engines crawl pages – that is when they send out bots to scan the page content – having main pillar pages clustered around sub topics allows the bots to crawl the main pillar page and any content connected to it.

So How Do Content Clusters Improve SEO?

• Boosts Topic Authority: When you thoroughly cover a topic, search engines recognize your expertise. This can help you rank higher for competitive keywords.
• Enhances Internal Linking: Clusters create a strong internal linking structure, making it easier for search engines to crawl and index your site.
• Improves Keyword Targeting: Supporting content allows you to target long-tail keywords and related search terms, expanding your visibility.
• Increases Dwell Time: Clusters encourage visitors to explore multiple pages, increasing the time they spend on your site—a key ranking factor.

Step-by-Step Guide to Creating Content Clusters

Choose a Core Topic

Use keyword research tools like SEMrush or Google Keyword Planner to identify high-traffic topics that align with your niche. Select a topic broad enough to support multiple subtopics. But don’t make it too competitive. Some topics are hard to rank for because there is so much information already online.

Create a Pillar Page

Write a comprehensive guide on your chosen topic. This page should answer broad questions, provide in-depth insights, and importantly link to your supporting pages.

Develop Supporting Content

Write blog posts focused on specific subtopics. For example, if a highly-searched, non-competitive keyword is ‘SEO Essex’, your supporting page might be “How to take advantage of local SEO”.

Implement Internal Linking

Link your supporting pages to the pillar page and vice versa. This creates a web of interconnected content, improving navigation and SEO signals. Effectively it prevents a dead-end page scenario with no links for bots to crawl and move forward. Doing this tells search engines which page you want to be known as the pillar pages and therefore show search engine users your expertise.

Update and Expand Regularly

Keep your cluster fresh by adding new supporting content and updating existing posts with the latest information. This helps maintain your rankings over time.

Clustering in this way not only improves your search rankings but also provides a seamless experience for users looking for related information.

• SEMrush: For keyword research and identifying content gaps.
