this is the way i see it. it's very simple and based on many recents tests i made (some of them even posted here on BHW)
Unlisted = not indexed yet on youtube
when you upload a video straight up as unlisted (this is the most important factor, it MUST NOT get to be public at any point)
this way you have a video that didn't get indexed yet, you can take your time now to send as much traffic as you want (the more is the better)
after a few days (2-4 usually) you go public, and youtube is going to index the video and credit the boosting as a "trending" video,
as if ALL the views came along on the public hour at once...
so unlisted video that got 100K in 3 days when it will go public it will seem to youtube as it got all that traffic at once (just like a real viral video...)
with that comes a boosting effect that's called the "unlisted method"
NOTE: very important for those who says it's not working for them
the boosting effect will work only on locals where your traffic VPH is over the average VPH at that day
example: if my public video gets traffic that contain 10K per day from india (that's average of 400 VPH = not enough)
but if unlisted for 5 days and then go public - the effect will be similar to 50K per day and 2000 VPH, and my video will have a great chance to rank and trend on INDIA
(this will work only if 2000 VPH is faster than other top videos getting)
again, this is the way i see it and different traffic will lead to different results.
Yes I figured that our but everyone says it doesn't work . I haven't tried exactly this method yet so idk, but I will try it. Only problem is that I get about 50-200 views per hour . Are you sure about what you're saying is true or are you just using logic ?
