Use relevant hashtags in the description of the post. Make sure you are posting at the right time of day for your fans. Make sure you have LOTS Of fans on your page to view it, if not run FB ads to the content to increase the reach. Ask an enticing question in the description that is only answered in the video. Embed directly onto FB, do not post a Youtube link, you get way less reach with that. Grow social proof but getting people to like, comment and share the content regularly, create a brigade of supporters who will help spread the message. Use ads to grow your page with targeted people and then use ads to promote the video's. I'm happy to get a call with you if you have more questions.
