I post videos through this service in my VK, OK, and FB groups. The main thing to consider is that if you have few followers (preferably real people, at least fakes, but not bots), you shouldn't even try to contact Vibum. Even if they don't refuse you (which is unlikely), you'll earn just a pittance. After all, the profit comes not from the placement itself, but from user clicks on the videos. Views are counted even with accidental clicks on the video, both on computers and smartphones (it's just super easy to accidentally tap on a video, and that counts). A view is also counted if someone reposts the video on their wall and someone watches it. In the Vibum personal account, it's convenient to track the advertising campaign: how many views on each platform, how much profit per day, and there's an immediate list of videos for placement. Overall, earning is quite simple if you have a promoted platform. I earn the most from my VK group – about 13 thousand a month, a little less from the American equivalent – 10, and classmates bring almost nothing – a maximum of 5-6, although that's not bad either. In general, the total income pleases both the heart and the wallet.
