There is no specific way to accumulate millions of followers on Facebook but instead overtime and through testing content strategies it's possible to get there. You are right in assuming that a lot of this is not organic. Facebook as a platform is becoming more PAY-TO-PLAY, so creating a huge following without paid initiatives is very difficult. It starts with content when looking for strategies to reach these levels. By identifying low effort, high reward content types and testing their validity through short term paid promotions, you can get immediate feedback from your target audience around if they found value from it. From there you should begin to double down on what's working and find ways to enable this content machine to keep running. I wouldn't overlook the monetization of this audience though. Building an audience for maybe "1 day" monetizing it is foolish. If you want discuss in more detail specific strategies for building a following for your idea, feel free to schedule a call.

Discounts or free service incentives are just part of the equation. You first need to capture your prospects attention with a value driven initiative. Ideally you want to build a level of trust and authority with that prospect through multiple touch points. By focusing on adding value first, you increase the likelihood that your prospect will care at all about your free discount or free service incentive. I'm not sure what type of business you are in (B2B, B2C, Online, Offline etc.) but this determines the types of mediums that would fair best in delivering that value.
