The 15-minute weekly Shorts review that actually changes output

Don't drown in dashboards. Run this same loop every Monday.
— Sort last week's Shorts by average view % (not views) — your real quality signal
— Take the top one: write down the single thing it did right, do it again next week
— Take the bottom one: find its retention cliff, name the mistake, ban it
— Check which hook style (text/spoken/visual) the winners shared
— Note publish-time of the top 3, nudge your schedule toward it
— Write 3 next-week hooks based on what won — close the loop immediately
Tool: YouTube Studio, free. No third-party analytics needed at this stage.
Verdict: review by retention %, act on exactly two videos, ignore the rest. Skip paid analytics suites until you're past 10k subs. Not for data-hoarders who analyze and never adjust.
