I have a Facebook yoga page. I find it is ok for students who know they want to look at my weekly schedule, or follow my blog posts, or message me to see when I am teaching, but I have not found it ideal for promotion.
Facebook is now offering promotional services. You pay and they send your posts to a wider audience. I am not convinced that this is the best usage of advertising budget.
I would say more people I know use linked in for professional networking. I do not, but that is because I am in the dark ages vis a vis technology, and it was a big step for me to take a class at my library to figure out Facebook.
What seems to work for a lot of people I know to some degree is linking a Facebook to a web page, and a twitter account, and an IDEAfit profile…. Kind of like building a series of interconnecting roads to let traffic flow in from as many places as possible.
It also helps to post often (which energy could maybe be spent elsewhere… but that is always a balance, isn’t it)
You could also join local fitness pro Facebook groups and repost from those groups. I belong to two yoga groups and one philosophical discussion group. Both yoga Facebook groups are heavily used by people posting various classes and workshops, …. I am part time so don’t do that much, but if you have a place like that to repost you will get a wider audience.
This is a question I have pondered for a while, and I think if I were to go full time again I would build a web site and use that more than the other.
I hope you get lots of good tips, and will check back myself. 🙂 Good luck.
