How would you measure the success of YouTube Shorts?

What They’re Really Asking

Do you understand the difference between vanity metrics and value-driving metrics for short-form video?

Strong Sample Answer

For YouTube Shorts, the North Star Metric should be 'Total Time Spent Watching by Returning Users,' balancing consumption with retention. However, success isn't just watching; it's creation and ecosystem health. I'd use a framework of Input and Output metrics. Primary Output: Daily Active Creators and Viewer Retention Rate (did they come back tomorrow?). Secondary Output: Share rate and Subscription conversion (does Shorts drive long-form growth?). Guardrail metrics are crucial: Cost per Stream (bandwidth) and negative feedback (clicking 'Not Interested'). We must avoid optimizing solely for 'Views' as it encourages clickbait. Instead, we track 'Satisfied Views' via surveys or implicit signals like re-watches. If time spent goes up but creator count drops, the ecosystem is unhealthy. Therefore, a composite score weighting consumption, creation, and satisfaction gives the truest picture. This ensures we aren't just addicting users but building a sustainable creator economy that feeds the wider YouTube platform.
