Probably it's 1 page = 1 view. So if your chapter has 20 pages it's 20 views.
Personally I don't believe in Webnovel views. I don't read my story (only in Inkstone when I edit chapters) and still I have about 100 views everyday... with no comments, no collections, no rewievs or any human-like activity.
It's either some bots dropping those views or I write such boring novel that almost everyone who ran across it gives a try and then drops it.
But this view system gives some impressive numbers. 20 million on a novel that would gain 100k on other platform. It looks amazing.
