They have more than 100 subscribers because they consistently crank out good, quality content that more than 100 people want to see.ok, but from my experience, u guys r deadly wrong.
I made several tests in the past. Every time u search something on yoiutube videos from channels with from 100subs up only will show up. That's just the reality. U wont find any videos of tiny channels. Unless u filter last few hours or somehting,
Youtube likewise algorithmically promotes them because their videos consistently get high click-through rate and long watch time because they are good videos.
See the connection, here? Making good content will give you both subscribers and algorithmic promotion, but those two rewards are totally independent of one another.
Also, reddit is a great way to get eyes on your videos when the youtube algorithm doesn't trust you enough yet to promote you.
