I haven't done a lot of research into Facebook. But most of the products I see are either graphics-related, get customers to like pages before accessing some content and also app creation. I feel that the graphics and getting the likes can help businesses increase customers, but not that much and not that dramatically. App creation can do more if done well I think. The thing about FB is to tap on the viral. The best way I can think of is through some app or quiz competition or whatever that attracts people to be part of it and gives exposure to the business.
I may be wrong, but I haven't found a really good system to really help offline businesses through FB (maybe creating some apps that do that). There's been a lot of hype over the latest changes and you can get some money with a one off creation of some graphic-related service or whatever. But I'm thinking long term. How can we really serve businesses continuously with FB? Something that really increases their customers and is not just the latest hype going on.
Do share how that can be done. If there are any really good FB WSOs that do that, also do let me know. Like I said, I've been focusing on SEO and GP and so I've not been really up to date with all this FB stuff. So I'd appreciate input.
