Video Completion Rate (VCR)
The primary creative quality metric that dictates CPM and algorithm distribution
In Simple Words (Zero Jargon):
The percentage of viewers who watched your video all the way to the final second without swiping away.
Official Mathematical Equation
VCR% = (Videos Watched to 100% Completion ÷ Total Video Views) × 100
Why It Is Critical
VCR is the #1 metric evaluated by the FYP algorithm. A high VCR rewards the ad with cheaper CPMs and viral distribution. A low VCR triggers ad suppression and expensive CPMs.
Calculation Example & Benchmark Matrix
| VCR Range | Performance Rating & Action |
|---|---|
| Below 20% | Poor - Video is being skipped immediately. Rewrite the opening 1-2s hook. |
| 20-40% | Average - Acceptable for longer videos (30s+), but weak for 15s formats. |
| 40-60% | Good - Creative is resonating with audience. Scale budget before fatigue sets in. |
| 60-80% | Strong - Top-performing creative. Maximize spend behind this video immediately. |
| 80%+ | Exceptional - Rare for paid ads. Analyze the hook structure and replicate for future assets. |
