I have tried FB advertising for several opportunities and yes it does work but it is important you have a fanpage to direct your advertising to. FB much prefers if you keep traffic on FB so having a fanpage does this for you. You can have more than one fanpage so you can set one up especially for SFI and have lots of information there for people. FB gives you the name of your fans so you can always message them about SFI and Tripleclicks etc. Hope that helps.
