Get more traffic so more people and can watch your video. The higher the number of views your video is receiving, the higher the number of likes it will be getting so far as the video is a pleasant, entertaining, or informative one.
What I would do is join Facebook groups, g+ groups, LinkedIn groups that are all relevant to your video topic. Become active in the group and share your content and videos in that group.
You could also do the same in relevant forums.
