A topic cluster is a group of interrelated content pieces or web pages that cover a particular topic comprehensively. In content marketing and search engine optimization (SEO), topic clusters are used to create a framework for organizing content around a core topic, with subtopics and related topics branching out from it.
The idea behind a topic cluster is to improve the user experience and help search engines understand the content by providing a more comprehensive and connected coverage of a particular subject. By linking the content within a topic cluster, it allows search engines to recognize the context of the content and the authority of the website.
For example, a topic cluster for a website about fitness could include a core page on "Fitness for Beginners," with supporting pages on subtopics like "How to Create a Workout Plan," "The Benefits of Cardio Exercise," and "Strength Training for Beginners." These pages are all linked to each other, creating a web of related content that demonstrates the website's expertise on the subject of fitness.
