Content clusters make content pruning easier because they show which articles still support the main topic and which ones no longer fit well. A content cluster means a group of articles that all explain one big topic from different angles, while the pillar page is the main page that links to all of them. When some articles stop getting traffic or no longer match the main topic, they can be updated, merged, or removed. This keeps the site focused and useful. Does this approach make sense for long term planning?
