A near-synonym for content pillar, often used to describe a recurring content format (e.g. "Tip Tuesday", "Case Study Friday") rather than topic.
Content buckets and content pillars overlap, but pillars usually mean topics and buckets usually mean formats or recurring slots. A "Q&A Wednesday" series is a bucket. A "deal breakdown" pillar is a topic. Many accounts use both — pillars for what they talk about, buckets for the recurring structures.
The framework helps with planning: "Tomorrow is Tuesday, which means tip-Tuesday bucket, which I'll fill with a pillar-2 topic." Two layers of constraint make content generation almost mechanical, which is what consistent creators want.
Inside Kompozy, the "buckets" word also refers to the 5 output-type categories (Video, Image, Text, Blog, Newsletter) — a separate meaning, context dependent. Topic pools handle the "content bucket as recurring slot" concept.
