In one day, a Facebook page of ours went from 11 fans to 3,440.
How did we do it?
Well it's another benefit you have access to if you're willing to spend some money that earns you a relationship with the Facebook team.
From there, all you need is an existing fan created page. Unless it's already being well managed (see how Soap approached the Bubble O'Bill page) a dead community on an inactive page is a waste. As it stands, these fan create pages are technically not allowed and are a breach of copyright/trademark/legal stuff.
Facebook will delete the page and migrate the fans across to yours.
You can expect a small drop off from fans who haven't heard from the page in potentially years, but also a fantastic response from a now ignited community who have been otherwise dead.
And that's the quickest way to grow your fan page....
