Hence, it can be seen that when clustering is used, the main thing which it is meant to focus on is the different aspects so the writer can select a broad topic for writing. “Cluster” or supporting pages that cover related topics in more depth. A cluster page tends to have a narrower focus on a specific user intent. This approach isn’t just “find a long-tail keyword and write about it.” It’s about going deep on a particular topic. Internal linking between all of the pages. Links from the cluster pages ...Rearrangement should be done as if the correlation coefficient of the individual's liking and the cluster centroids is higher than 0.6, then it should be placed in that given cluster. If there is no cluster where the individual can be placed ( e.g., there are no clusters that have an r > 0.6 with the individual), then the individual should be clustered as “other”.clustering should be flexible w.r.t. the underlying cluster-ing model. General processing schemes, data structures, and dissimilarity models are desired.

In Clustering the objective is to assign labels to objects (or observations, or data points). A set of objects that have the same label (or labels) is said to be a “group” or a “cluster”. The aim of clustering algorithms and heuristics is to achieve the best possible grouping. For this strategy to work, the topics on your pillar pages need to be well-defined.
