YouTube pays based on views, not subscribers.
You may be wondering why YouTubers are constantly asking viewers to subscribe if they aren’t getting paid per subscriber. First of all, subscribers get your videos directly on their homepage, making it easier for them to click on your new content and raise your viewer numbers. A large number of subscribers is also a sign to potential viewers that your content is worth checking out. YouTubers can also use a large subscriber number to pitch themselves to brands for sponsorships.
