Why don't my youtube videos have as many views as the other youtube videos?

I uploaded 6 dry ice bomb vids onto youtube. I noticed after a few days that I only had 5 views on each. I then searched for other more recent dry ice bomb videos and they had over 8 views within a few hours. Also my videos are a lot better than theirs in quality and the size and loudness of the explosion. I also put as many popular tags as i could use and named each one Dry ice bomb...
