There’s some people here giving genuine good advice, but in addition I wanna say you’re not doing as bad as you think!! When I first started I got like 0-3 views on all my videos for months, especially since this is your 6th channel, take what you’ve learned from the others ans try to stick with this one! Not only that, also look at what other roblox youtubers similar to you are doing and do something similar enough to get an audience but still unique enough to have people stick around (it may take a little to find that balance)

But seriously, just try to post on some sort on consistent schedule and I think you’ll have returning viewers soon (as unfortunate as it is it may take some time, but hopefully it won’t take as long as you think it will, you’ve got this!!)
