Cause I'm really curious how they are ranked and why are they ranked like this. Stars, Views, Likes/Dislikes, Reviews, On reading list, Chapters, Release frequency Or something else or all together?
AFAIK for popularity month its more on activity of the novel (more weighted on how many people use the link to novel chapter) altho it count the other thing too.
I am guessing you are asking on what basis the activity/popularity is calculated? popularity is most likely based on how many people have it in their list+the ratings activity depends on how many of its releases gets clicked on in certain period of time. I am guessing this.
