Pillar pages serve as the foundation for a particular topic cluster. They provide an overview of a given subject area and provide links to deeper resources on specific subtopics within that area. Pillar pages should provide detailed information on their respective topics without going too far down into any single subtopic - this is where the related articles come in! A good pillar page should provide enough general information that readers can get a good understanding of what they need without having to go elsewhere for more information. The goal here is to provide readers with an easy-to-navigate source of information on whatever subject matter you choose to write about.
