Youtube Ranking Factors Question

Hey guys, regarding youtube ranking factors, I pretty much know which ones are important (title, tags, likes, comments etc.) but does anyone know the order of importance? For instance, are favorites more important than comments, which are more important than likes?

I found only 1 source that had this information, but am not sure if it is outdated or still true:

Edit: I cant post links yet apparently

Anyways, According to this source, order of importance from highest to lowest is:

Keywords in title
Membership age
# of Favorites
# of Subscribers
# of Comments
# of Likes
Total Channel Views


I appreciate the feedback!

Views and subscriber are more part of it.

The most important thing is on page SEO (title, description and tags)! Then it's reterntion views (50+% retention), likes and comments! Favourites and subs doesn't matter in my opinion. Subs just increase your convertion rate.
