I got this in my inbox the other morning, ""I believe FB is much easier and most used by consumers than websites. People will check out the website only once and not bother to go back... it is a waste of money and time... almost everyone is on FB now... and people can get instant updates from there as well. FB is free... who do you work for???
Brief advice version - google is the biggest search engine, market research shows that youtube is now the worlds second biggest search engine, billions of people use those two search engines, versus only millions using FB. You couldn't even put half as much information on FB as you could on a web site due to FB policies, therefore limiting "business details". Most people on FB in groups think when you're sending them messages, that you are spamming them and don't even know why you're sending them a message (personal experiences - that happens to me a lot). You maintain full control on your own web site, where here we have to abide by what FB says we can and can not do. Most people on FB are using it to socialize with family and friends and tell us what they're doing, they could care less about "other stuff" - this is from a few exp, not only my own, but I do know some people have had great success with FB promo's - so that could vary, but generally I think my results are accurate.
I've got more advice but anyone care to add? And I'm going to point her to this thread
