I'll pretty much just be reiterating what has been said.
-your views should be high retention. Also, drip feeding seems to be the most legitimate way to use view boosting. I personally don't boost, but I've read this over and over.
-as mentioned already, upload your own transcript/closed caption.
-sounds like you're over optimizing your keywords. Chose a few KWs to go after, and when using meta tags don't over do it as well(like 10 tags max). Likes, comments, and channel subscribers help along side with views. Be sure that your Keywords are within the first 60 characters of your title.
-make sure you are using a HQ/HD video.
Keep in mind rank a largely based off of competition.
