We studied 2.6 Billion views to decode the YouTube Shorts algorithm. • What metrics make a short viral? • What’s the most you can make with shorts? • Are shorts better than long in 2025? Here's our findings:

For this study I downloaded the data from my YT Shorts channel with: • 316 Shorts posted • 2,637,646,780 views • 1,200,000 followers • $170,000 made from AdSense (all achieved in the last 6 months, so the data is the most relevant)

Let’s start with a question: “What metrics make a short viral?” We found two. Only two metrics ACTUALLY make your videos go viral. Let’s start with the 2nd most important one: Swipe Rate

How Swipe Rate affects views Correlation between Stayed to Watch % and Views = +0.13. When we plotted Views vs Stayed to Watch %, the big 10M+ hits (green dots) almost all sat above 80% Stayed to Watch. Below 70%, videos rarely cross into the 1M+ tier.

So what’s the most important metric? Average View Duration. Correlation between AVD% and Views = +0.31. That’s the strongest relationship we found in our study (stronger than video length, swipe rate, likes, comments, etc.). Meaning: the deeper people watch your video, the

You can notice a solid trend that I marked with blue lines. Only 3 videos with less than 100% AVD got more than 10M views. Which means that high AVD almost guarantees your videos are going to go viral. I aim at 115%+, however this metric is only valid for 20–25 second Shorts.
