Look at who you are competing with, there are barely any views above a thousand with that topic. You may have gotten lucky with view/watch time as well since you being on the 3-4th list down with 370 views already proved my point of how no one is really competing for this keyword. No big name YouTuber have covered that either. I wouldn't be taking any SEO advice from someone who didn't at least read the SEO facts or discussions on this forum. "Tag efficiently"...alright man, be uneducated about SEO all you want, I'm done here.
