If you are wanting to maximize your Youtube views then you need to ask yourself one question...are you looking to provide education or entertainment? After you have answered this question you can begin to optimize for either category. Although education for many different topics on Youtube is in sort of short supply, so it might be a pretty easy sell these days. It all depends on the niche.
If you want to have a lot of views on your videos than go with either an educational or entertainment slant. After that you need only optimize and do some promoting.
have you tried linking your youtube channel to your facebook page youtube has so many videos that coming up in the first general serch is unlikely but this way you can advertise it on your facebook page, which is much easier to advertise to a large audience hope this helps
