So I am much more concerned with my ranking on Google and what happens when people get online to search for a cake decorator in my town. People who stick strictly to Face book to find vendors tend to be on the lower end of the budget and rarely ever order. They want to message about a cake, they want to text, they want to order on my wall....nah. Don't ask me how to explain why I think all that is true, it just is from my experience in my area.
That is true, I don't think it should be the only business tool, but it could be a good for advertising as a link from your main site, twitter too. And who doesn't want their bakery to pop up in the top 10 searches on Google,lol.
