Good content, good quality; great!
Make sure you have good tags, keywords and metadata. Incorporate your videos in responses, forums, e-mails, etc. Create backlinks to your channel; engage with other partners in similar industry and keep on producing. The more you have the better shot at being discovered. I get most of my views from Google; the algorithm mixed with positive reviews and shares boosted my "SEO" organically for example; again its the content quality and proper tagging which helps organic view gaining.
My friend does something else; I may try. Google "Google Alerts" and create a Google alert for a keyword your video is about; Google will send you every night an alert containing any blogs, forums, discussions that mention your keyword; you can than comment and look for distribution sources on those sites; its really clever way of "white spam" but he has over 1,000,000 views because he's spamming good content. Just a thought for you.
You never want to use dirty spam tricks; you can lose credit and gain even less views. Engage your audience properly to keep them coming, ask them to share, thank them, etc. Most of all keep on producing great content and be patient, and you'll be good.
