I've Got It
Last year, I uploaded a video and it did pretty good, was getting 500 vph ( that was good for me ) and a few days later I realized it had no tags or description, and for some reason it did as good as all my other recent uploads, so really tags and description likely have no input on a videoyou are right,
I got some info but it is not proven. They think that manual human raters rated lots of channels and videos and chose what's good and what is not. All this data was fed to AI. Then they trained the AI to learn what is good and what is bad. And of course youtube launched a raw version of AI creating all this mess. So now it is not just tags and watchtime it's the computer that decides if your video is bad or not right after you uploaded it.
