I'm starting a fan page soon, and I plan on spending quite a bit on ads to build up a solid fan base. I also plan on creating a custom landing tab and capturing as many emails as possible. I've read that it's best to pick a niche with adults 18+ because they're going to be more willing to spend money. Also, to pick a fairly specific niche. I've thought along the lines of Cooking (Targeting moms), fishing, or getting fit... What niche do you guys think would be the best?
