What Are Topic Clusters? Why (& How) They Help With SEO

Topic clusters are a content strategy and SEO approach that involves organizing your website's content around a central pillar topic and related subtopics. This strategy can help improve your website's search engine optimization (SEO) by providing a more organized, user-friendly, and authoritative structure for your content.

Improved Content Relevance  

Topic clusters allow you to create content closely related to a central pillar topic. That increases the relevance of your content, making it more attractive to search engines.

Search engines provide the most relevant results to users, and organizing content this way signals to them that you are providing comprehensive information on a particular subject. 

Better User Experience

Organizing your content into clusters makes it easier for users to find information on your website. When users find your content valuable and easy to findout, they are more likely to spend time on your site, reducing bounce rates and increasing the chances of them converting or returning.

Avoiding jargon is needed by SEO experts as users are not comfortable with difficult words and Google algorithms to identify and display to users.

Authority Building

Creating comprehensive content around a central topic and interlinking it demonstrates to search engines that you are an authoritative source. Google rewards traditional websites with higher search rankings, leading to improved visibility and increased organic traffic.

Since the beginning, Google has stood on authoritative content, and SEO marketers must follow Google's guidelines to rank their pages.

Long-Tail Keyword Targeting

Topic clusters often include long-tail keywords (more specific, less competitive keywords) as subtopics. Creating content around these long-tail keywords can capture a more targeted audience interested in those particular topics. That can increase organic traffic from users searching for these niche subjects.

As new technology has emerged and different tools have come into the picture, voice search tools are identifying long-tail keywords. So, SEO professionals should include long-tail keywords in the content.


Topic clusters involve interlinking the pillar content with related subtopic articles. This internal linking strategy helps search engines understand the relationships between your content pieces and can improve your website's overall SEO.

It also keeps users engaged by guiding them to other relevant content on your site.

How to Create Topic Clusters for SEO

Identify Your Pillar Topic 

Choose a central topic or theme that is broad and relevant to your website or business. This topic should serve as the primary focus of your content strategy.

Research Subtopics

Research and identify subtopics related to your pillar topic. These subtopics should be more specific and cover various aspects of the central theme.

Create Quality Content

Develop high-quality content for both the pillar topic and subtopics. Ensure that your content is informative, well-structured, and provides value to your audience.

Interlink Your Content

Link your subtopic articles to the pillar content and vice versa. This internal linking helps to navigate your site and help signals to search engines that your content is interconnected and authoritative.

Optimize for SEO

Optimize each piece of content for SEO by including relevant keywords, meta descriptions, and other on-page SEO elements. SEO agencies in the UK should follow these steps and optimize to get the expected results.

Promote Your Content

Share your content on social media, email newsletters, and other channels to increase its visibility and attract backlinks from other websites.

Monitor and Update

Regularly review your content and update it as necessary to keep it current and relevant. This demonstrates your commitment to providing accurate and up-to-date information.
