Has anyone had any luck with paid Youtube views/comments/ratings/subscribers providers? It seems everyone promises "real" people to do these things, with the prices increasing based on how "natural" the promotion is, but I rarely see any benefit in the campaigns I've tried. I've tested with new videos and videos good on their own (meaning videos that acquire attention naturally), but no Youtube service provider has shown noticeable conversions.
If you have a favorite Youtube provider, please share here and explain your experience with them. Thank you.
