So far I have upload around 20 videos. Most of them are street fight videos that I found on yt and other sites. I have a few of me playing SC2 and I have one video that is a review of a binary options site that I made. I have noticed that the earnings I get from the review video are at least 5 times higher than the other videos. ( 20 in some cases). All this with about a third of the views of my biggest video. Some of the reasons I thought that could make this happen are: this video is unique and 100% original, the niche is more serious than the others, or the niche has a higher cpc/payout. I have made the conclusion that I will only post video that I have made, but I am curious as to what I should make video about. Should I only make videos for one good niche. Or should I make a few videos per niche. Any suggestions?
