I won't name the site here because the owner is here also but they ask to buy 5000 CTR views worth $75 to even rank low comp keywords..
I bought 500 views worth $7.5 & even though the CTR was boosted, the video & none of the keywords got ranked...Means YouTube can detect the fake CTR views too now, so no use of boosting CTR from these panels by paying such high prices... They charge anywhere from $20 to $100 per thousand CTR views & they say they can't give any ranking guarantee...No stay away from these...
I am yet to find a good panel for YT too...You will ask thousand people here & all those people will tell you the names of 1000 different panels as some are the affiliates/owners of those panels & some people will just randomly write any panel name without even testing them personally so you will never find the panel unless you test all the panels yourself by wasting a lot of money just to find out that 99% of them are crap.
