Content clusters, also known as topic clusters, are a strategic approach to organizing and linking related content on a website to improve search engine visibility and user experience. Content clusters consist of a pillar page, which serves as a comprehensive guide or overview of a broad topic, and multiple cluster pages, which delve into specific subtopics related to the pillar page. By interlinking these pages within the same thematic cluster, website owners can establish topical relevance and authority, signal to search engines the importance of the topic, and improve the overall ranking and visibility of the cluster in search results.

Implementing content clusters involves conducting keyword research to identify relevant topics and subtopics within a specific niche or industry. Website owners then create pillar pages that provide comprehensive coverage of broad topics and cluster pages that address specific aspects or subtopics in more detail. Interlinking these pages within the same cluster and optimizing them for relevant keywords and search intent helps establish topical relevance and authority, leading to improved search engine rankings and organic traffic. By leveraging content clusters, website owners can enhance their content strategy, improve user engagement, and increase visibility in search results.
