Cluster cohesion means all articles in the cluster must connect to the main topic, while content variety means the articles should not all sound the same or repeat the same ideas. This balance can be achieved by covering different angles of the same topic, such as guides, tips, mistakes, case studies, and simple explanations. The topic stays the same, but the way it is explained changes. This keeps readers interested while still keeping the structure clear. What is a good way to plan these angles before writing?
