Over the past few months, we have utilized YouTube's Promotion feature. We found that often it did help with subscribers and views. We don't use it often and only spend $50 per campaign. This past week we did boost a video on 12/26. While YouTube showed our subscribers jumped from 50 in 28 days to over 700, we actually LOST 200 subscribers. What's even stranger is, for the first time, the video we boosted got over 20 comments from obvious "paid watchers"....most had handles with a number in it and they all said the exact same thing. What is everyone's thoughts and feedback on this?
