Between SS captures variability between clusters. When it increases, it indicates better clustering because within cluster variability will come down. Elements within a cluster should be closer to each other whereas elements between clusters should be further away for a good cluster formation.

You can increase or decrease number of clusters and see which one improves between cluster distance.

This video explains exactly that. Different rows in the data used are different companies and the idea is to try and group them into clusters based on the quantitative variables.

When you look at cluster means for each cluster and each variables, large differences in means for a variable will indicate that the variable has contributed significantly to cluster formation. It helps to characterize clusters.
