Be careful. The issue here is watch time. “Blasting” over Reddit with friends upvoting your posts definitely leads to views. But if the subject isn’t what they’re interested in and they click away 30 seconds or 1 minute later, then you’re actually doing your channel a disservice. Racking up lots of viewers that click away seconds or minutes after pushing play is a signal to the YouTub algo that the video stinks, thereby cutting yourself off at the knees when it comes to YT promoting your video organically.
This is basically the new version of Sub4Sub, where you get lots of hits but no one sticks around to watch. Do you have an eye on your total video watch time minutes and view duration?
Now obviously, posting links in subreddits that relate to your niche (travel, cooking, etc) is a great idea. But “blasting” videos to general subreddits like “/videos” and “/newtubers” and “/YouTube” tends to lead to viewers “doing their duty” and clicking play only to immediately dump and move to the next one, hoping someone does the same for them. That’s literally the definition of channel-killing material.
TL;DR: 10 viewers that genuinely watch your entire video and engage in the comments is much more important than 100 viewers that watch 45 seconds of your video and dump to the next one in the latest “sub4sub” scheme. Just be careful out there!
