Basically you want a balanced approach of all the above. Lots of YouTube video views, comments, likes, favorites, etc. If you have a good balance of those your video will rank higher on YouTube's search results and, also, this is a bonus, Google's. If you can get a YouTube video to rank at the top of Google, it's major traffic. Major. And I've found the videos hold those positions for a long, long time. It's a consistent traffic source.
