01 / THE DEFINITION
CTR (Click-Through Rate), explained.
Click-through rate is impressions that turned into clicks, shown as a percentage in YouTube Analytics. It's driven almost entirely by your title and thumbnail (your 'packaging').
02 / THE CONTEXT
Why it matters for growth
Low CTR means the algorithm stops showing your video — even great content dies behind a weak thumbnail. Scanning your channel surfaces which videos are bleeding clicks.
