I have a set base of keywords that I pulled from some other random YouTuber that posted about Make.com. Then I add another 100 characters or so myself specific to this video. I mark the clip as "English", go through the monetization steps, and then click "Publish". I don't take YouTube's recommended advice to leave it as "Unlisted" until they're done checking it, doesn't matter to me if a video isn't monetized.
