To get your video on google, its a good idea to have some backlinks of your video. This should help with onpage.
Get lots of views, subscribers, and favorites. You don't really need likes and comments. I mean, u may find yourself disabling likes and comments for some reason.
Most important!!!
Put your title in your description, and tags. Use youtube keyword research and google keyword research. Be sure to google the keyword to see what you are up against. If you only see one video onpage, you have a good shot. If you see 2, you need to overtake 1. If they don't have many views, go for it.
