I really don't know what works anymore. HR views dont work for me , normal views don't work for me either. In both cases my videos either dont get ranked for high search volume at all ( unless I buy 50K + ) or they do and 1 day later they get lost in the ocean as someone said above . The only reason why I still buy HR views is to keep the good rep of my channel .
As for fast views , i dont think they work either. My views provider accidentally gave me 60K in just a day a few weeks ago when I ordered 10K , guess what , I got ranked for med comp keywrods , I don't really care about that , I only care about high comp , med comp, let alone low-comp is completely useless. I did get ranked for one or two high comp but it only lasted a day once again.
I did try buying more comments on top of the legit ones I get and a lot more likes, still no change.
YouTube is basically catering only to already established and news channels ATM. ( why news , it's cuz a lot of times there is barely any competition if you post something new first and a lot of people will be searching for it )
YouTube needs a change in algorithm , promoting newly posted videos for ALL cattegories , rather than videos that got a millions of views. If a video is older than a month , it loses it's rank , it is no longer on top of search results. The problem with youtube is that a lot of categories are completely dominated by huge channels who got millions of views on their video and those videos stay there for months/years . THIS IS THE PROBLEM. A newly posted video with lets say 30K views should have double the power of a 3 month old video with 3 million views .
