I have an update on this... and it looks worse than I thought.
I went through hundreds of shorts that I uploaded on multiple channels.
The fact that none of probably around 900 shorts went viral is statistically impossible, not with the quality of shorts that I make.
Reminder: I had 10 million views short on my gaming channel. 10kk views short metrics: 23s long 110% retention 85% view rate.
I found this short (see the atachment) on one of my channels - 82.8% view rate and 116% retention on 27s short. This is 5-10 million views metrics. It got 1.3k views and it completely stopped getting impressions.
I found more shorts with 91-92% view rate and 110-120% retention that got 1-3k views. There were some that landed in the 10-16k views zone.
I've viral shorts data from my gaming channel, I've seen about a dozen of other people's viral shorts metrics. Mine are much better and it's not even close. If you go to the 1st page of this thread, there's someone who got 7 million views with 57% view rate and 106.9% retention on 10s long short. There's Segaru's thread on this forum, he had a lot of success with shorts. My metrics beats his too.
It feels like all my channels perhaps excluding my gaming channel are just not allowed to go viral. No matter how good my metrics are (91% view rate and 110% retention are objectively viral shorts metrics) and no matter how many shorts I upload (around 900 shorts on 5 channels).
It feels like there's some sort of artificial limitation that I can't explain. Other people get 0 views or their shorts don't get views cause their metrics are objectively bad, and this is not the case here. I've tried different niches, I've tried everything... Improving the quality or uploading more shorts is clearly not the answer.
I'm open to suggestions. If someone wants to share their viral shorts metrics that would be cool too.
edit: another example of someone who went viral. His viral short metrics : 13s long – 76.4% viewed - 133.8% retention - 10.6m views
