What is the purpose of YouTube Subscribers?

Simply put, YouTube subscribers refer to those who are subscribed to your channel. If you upload a new video, your viewers will see it in their feeds. This will increase the likelihood that your subscribers will view the videos you upload. In theory you could get as many views as your subscriber count, (or more).

But this isn't always how it actually works. There are many factors that can affect how accurate these numbers are. https://youtubemarket.net/en/buy-youtube-subscribers
