You say you're dominating the search, and that's great, so most of the views are coming from search? Oh, and how is your retention on those videos? If you figure out a way to get ahead of the curve, like you did this time, just rinse and repeat and hope for the same results, continuing to do whatever you can to improve your content. People searching specifically for what you're pushing plus quality content should equal high retention and longer viewing sessions, which should help those videos where it really counts which is getting ranked highly by the suggested video algorithm on some higher profile videos.
Great job. good luck.
