A content audit is a comprehensive review of your existing content library — inventorying every piece, evaluating its current performance (traffic, rankings, engagement), and making a clear recommendation for each: keep as-is, update, consolidate with similar content, or remove entirely.

It answers questions a single-post view can't: which topics are covered multiple times in competing, overlapping posts, which pieces have decayed and need attention, which are quietly strong and worth building on, and which are taking up space without contributing anything.
