What defines a topic cluster?

A topic cluster is best defined as a targeted cluster of relevant content covering a specific topic. This content strategy involves a core piece of content, known as the pillar page, that provides a comprehensive overview of a particular topic, along with several related subtopics that are linked to the pillar. These subtopics, often in the form of blog posts or articles, delve into more specific aspects related to the main topic, helping to create a structured and interconnected content framework.

This approach enhances SEO by signaling to search engines that your site contains extensive and relevant information about a subject, thus helping improve visibility and ranking. It also provides value to users by organizing information logically, making it easier for them to explore and find the details they are seeking.

In contrast, the other options do not accurately represent the concept of a topic cluster. A series of emails covering specific topics lacks the structured interlinking of content that defines topic clusters. A comprehensive page covering a topic in detail might describe a single aspect but doesn’t encompass the broader strategy of interconnected content. Lastly, a collection of unrelated blog posts fails to meet the essential criteria of relevance and targeted focus that defines a topic cluster.
