First analyse the perfect time when your vedio got reach. and start uploading short in that time. then you should upload 4/5 shorts Daily .and then use trending hash tag.
open your yt studio app. go to analytics then go to audience you will find which time people watch Your video.Wow... 4 to 5 shorts per day for every day?
Isn't it too much?
It took me 3 hours to create a 1-minute short video when I first started it, but now it's taking 90 minutes per video.
Also, where in YT Studio analytics that I need to check to see the perfect time of my video getting reach?
