It seems that almost everyone is on Facebook today. This guide takes you through setting up a personal profile, taking care of a few things to protect yourself and then setting up a business PAGE which you can market or grow on and off line. It is clear and easy to understand and explains everything along the way.
Here is another facebook business page guide specifically for photographers, but as I look through it, it has lots of good tips that any business could use. This one is 24 pages with good illustrations and samples throughout, but require that you LIKE their facebook page to download the free e-book. http://blog.photoshelter.com/2011/05/new-free-guide-facebook-fan-pages-for-photographer.html
