I don't know if there is any guaranteed way to rank a youtube video Google or make it appear there.
if you have some tutorial video on yt, and if it gets traffic, and has the right keywords, then if you have luck, it could sometimes appear on Google search and could rank there for a while.
I think some smm panels could help your video appear there, but I'm not sure yet.
i mostly focus on internal traffic from yt.
I have not focused much on ranking yt videos on Google search.
In that case you can just isolate your new channels on a VPS, by using a new phone number and ip address, or even use the 'dolphin anty browser' if you don't want to get a VPS. dolphin anty is an anti-detect/anti fingerprinting browser.
if you manage your new channels via this method, then it won't get linked.
Dolphin anty is a closed source software, the problem with anti-detect browsers is you are entering your credentials on some black box and trusting them with it. Not a good idea imo.
How reliable is it to think VPS IP addresses are and will remain fresh?
It's all tied to the same AdSense accounts at the end of the day anyway, and they are going hard on this, that's how related demonetizations are probably happening now. Even accessing through manager accounts are putting channels in trouble. So you would need to buy AdSense accounts from some dodgy source or trust someone you know with their address, revealing you are into making content online which sucks.
Also im pretty sure their next step is to do verifications every X months where you will need to prove you are the owner, so if you own AdSense accounts not under your real identity you will be locked out of them. And this is all under the constant threat of unfair AI demonetizations.
I don't know a single person that has proven to monetize a channel recently while having another demonetized channel using the same AdSense, they get demonetized due related channel policy. And worst case, they can delete all of your channels if they feel like it. Also most people are going to be making content on similar subniches because it's a skillset you develop for years (i've heard some people theorizing that they may not be as lenient if you change the niche), but I doubt they don't consider it circumvention if the niche is different, assuming you manage to learn a brand new niche and do content that isn't trash and ranks well.
As far as uploading a number of videos and deleting your channel and trying again until the algorithm picks it up, you would need to be careful that you don't get your content stolen. Some people go around stealing videos from good new channels, so if you delete the channel you'll no longer be the oldest uploader when you reupload it. If you sightly tweak it the AI will detect it and compare it with the oldest reupload from the thief and they will consider the stolen video as the original video potentially shadowbaning yours.
Finally, making a new channel and not enabling "Advanced features" is probably a waste of time, wouldn't be surprised if they shadowban views unless you enable it, and to enable it without doxing yourself with your ID or video recording you are going to need an unknown amount of "channel authority" which means posting videos in a suboptimal state, which means wasting potentially good videos, but if you enable it with the verification methods, you dox yourself and they probably use this to check against other channels you may own. And even if you managed to get "Advanced features" without doxing yourself somehow, you are going to need to dox yourself anyway for when they apply the random age verification check, risking termination if they figure out the data isn't real.
