I have been doing a lot of reading on building a Facebook landing page. Im in the process of building my Facebook landing page with a video review and an opt in for email. Im probably going to be doing PPC to get people to my page. My question is though, once they "like" my page or enter their email address, whats the best way to capitilize on this? I know Facebook wont let me directly put CPA offers on the wall or anything. So what are some other ideas on how to monetize this.
