2. Cluster Pages: Specific, in-depth articles that address subtopics or long-tail queries related to the pillar (e.g., "Best Nutrition for Marathon Runners" or "How to Choose Marathon Shoes").
3. Internal Links: The "connective tissue" that links cluster pages back to the pillar and, ideally, to each other Content clusters: What are they and do you need them?.
