Buying a very small number of subscribers can increase the popularity of your page on Facebook. As a rule, when a user views a page on Facebook, they see the entire audience, all the subscribers who are currently subscribed to this page. The higher the number, the more likely it is that the current user will be interested in the project and subscribe to the Facebook profile or page update.
If your page has very few subscribers, the user will simply leave and may never return to your page again, and this will have a bad effect on the popularity of your page. Buy 100 worldwide followers all over your Facebook page and your popularity will increase! All new users of your page will see a lot of subscribers and will be added to you independently!
