Click-through rate
Shows how attractive your title and thumbnail are to people who see them. Compare it between your own videos rather than with other channels.
Retention
Shows where viewers stop watching. Big drops in the first 30 seconds point to the hook; drops in the middle point to slow sections.
What to change first
Low click-through rate: work on titles and thumbnails. Good clicks but low retention: work on hooks and pacing. Both good: make more videos like it.
Monthly review
Once a month, list your best and weakest videos, note the patterns and decide two experiments for the next month.
Example
Reading the data
Video A: high clicks, retention drops at 0:20 → the hook did not match the title. Video B: lower clicks, strong retention → better topic, weaker packaging; retest the title.
