I created a group on Facebook that got over 1million members in 28 days. I then sold the group on sitepoint for $10,000. I was offered $15,000 but had already signed for 10k My point is, there are plenty of people who would love to have a group with 1,000,000+ members and who will pay big money to take yours. The "message all members" feature goes away at 5,000 members, or else the groups would be worth much more. Here is my advice to creating 1,000,000+ member facebook groups: 1. Follow pop culture and if a big event happens, create a group around it. Try and be the first to do so and people will join like mad. Example: When Heath Ledger died and "The Dark Knight" came out, someone created a group entitled "Heath Ledger Deserves a Post Humous Academy Award for his Role in the Dark Knight." Not the shortest title but it gained more than 1,000,000 members within the month. 2. Play off of Nastalgia. A group called "If you remember this you grew up in the 90's" has almost 2 million members. It is all about discussing things about the 90's that people loved. 3. Experiments like 6 degrees of separation where the only point of joining the group is to participate in an experiment. These groups ask you to inivite all of your friends and usually go viral. This is the kind of group I sold (now has more than 2million members). My advice if you are planning on partaking in the Facebook group journey is to create a fake account and get a lot of fake friends. This way you don't have to spam your real friends when inviting them to join your group and they don't get pissed at you. Good luck!
