Hello. I always do on page optimization of the video perfectly. (title, desc, subtitles, tags). With that usually my vid gets indexed in seconds, and most of times in first 3 pages if its not too much saturated. I checked in ahrefs (Site to check backlinks/social shares) that the first position videos even for saturated things most of times have 0 backlinks and barely any social share. Here is what I tried to rank in youtube with different videos: - High retention views. - HQ social bookmarks. - 500 HQ backlinks (The vid shown up in Google, still at same position in Youtube). - 100 social shares in a traffix exchange private service (so 100% natural, not from same IP or anything). I even tried to mix them, or try 2 of them and 2 not and so on. All toghetar with on page optimizazion. I can rank anything I want to in Google, but I can't rank a youtube vid. Can someone explain me that? Youtube ranks randomly?
