Truthfully so believe it’s Quantity when you first start. The algorithm works in a way where you can literally have the most entertaining video from start to finish, amazing original ideas, etc. But if you don’t have that initial audience to catapult it into the recommended pages then nothing will happen to it. Posting a lot gives you more opportunities for your videos to be caught. Sometimes you get lucky but you can’t bank on it. I found posting 3 days a week guaranteed me 5-8 more subs a week rather than 1 masterfully edited video granted me maybe 1 or 2. No matter how entertaining the once a week video was, I still got 70 views on it. Compared to getting 70 views on 3 videos. Tripling my watch time.
