Content Audit
A content audit is where you evaluate the content you've already cataloged and determine its worth. Where a content inventory is mechanical, counting what exists, an audit is editorial. You judge whether each piece is accurate, useful, on-brand, and worth keeping.
The outcome is a set of decisions: keep, revise, consolidate, or delete. An audit is often where you identify ROT — content that's redundant, outdated, or trivial — and mark it for removal. The inventory tells you what you have; the audit tells you what to do about it.
