How many core topics (content pillars) should a business typically identify for their content strategy?

A business should typically identify 3-5 core topics (content pillars) for their content strategy. This range is optimal because it allows for sufficient breadth to cover key aspects of the business and its audience's interests without becoming too diluted or unmanageable. Fewer than 3 topics might limit content opportunities and audience engagement, while more than 5 can lead to a scattered focus, making it difficult to establish authority and consistently produce high-quality content for each pillar. "As many as possible" is impractical and unsustainable for most businesses.
